The best pressure canner for large batches is the All American 941, a 41.5-quart gasket-free unit that holds about 19 quart jars or 32 pint jars per run. For most households, a 22 to 23-quart model such as the Presto 01781 or the T-fal 22-quart is the sweet spot, holding 7 quart jars or 18 to 20 pints.
Most people buy a canner with the wrong size. They fill half the pot, run four loads instead of one, and spend an entire Saturday watching steam instead of actually preserving food. Capacity is the only variable that changes how long a harvest afternoon takes, and it is the one variable the spec sheet does not explain clearly.
Our team worked through eight large-batch canners side by side and compared them on the things that decide a long canning day: real jar counts, empty weight, how pressure is controlled, whether a gasket has to be replaced, and what stovetop the pot actually fits on. Two of these units are not USDA-style canning vessels, and we flag both clearly below.
If you are new to the hobby, our large-batch gear picks cover the supporting tools that decide how many jars you finish in a session. And if you are already preserving water, stock or broth in bulk, the storage side matters as much as the canner, which is why we keep a separate guide to pressure tank sizing for off-grid households.

1. All American 941 Pressure Cooker and Canner, 41.5 Qt
All American 1930: 41.5qt Pressure Cooker/Canner (The 941) – Exclusive Metal-to-Metal Sealing System – Easy to Open & Close – Suitable for Gas or Electric Stoves – Made in the USA
41.5 quart capacity
Holds 19 quart or 32 pint jars
33 pounds empty
Metal-to-metal seal
Pros
- No gasket to replace or ever fail
- Largest jar load here at 19 quarts or 32 pints
- Precision machined regulator weight
- Made in the USA by a family-owned maker
Cons
- 33 pounds empty so it stays on the stove
- Slow heat-up and cool-down from the mass
- Vapor lock can catch the lid at zero pressure
This is the canner to buy if your harvest arrives faster than one 23-quart pot can swallow. Nearly 9,800 owners rate it 4.9 stars, and the number that comes up most often in reviews is the load itself: roughly 19 quart jars or 32 pint jars in a single batch, which no other unit in this roundup approaches.
The 941 works as a pressure cooker and a pressure canner in one vessel, and the metal-to-metal sealing system removes the single most common failure point in aluminum canners. There is no rubber gasket to stretch, harden or replace, so a decade-old unit still builds pressure as long as you keep the sealing ridge lightly oiled.
What you accept for that capacity is weight. The empty pot is 33 pounds, and the body measures 15.25 by 15.25 by 19 inches, so it is not something you carry to a countertop store. Reviewers are consistent on this point, and one warns specifically against sliding it across a glass cooktop.
Heat-up and cool-down are slower than a 23-quart pot because of that mass. The trade works in your favor during a long afternoon, because the pot stays on the burner, holding pressure, while you fill the next set of jars.
Who the 941 suits best
It suits households that put up 60 or more jars of low-acid food in a season, and homesteaders canning meat in bulk. One owner on r/Canning describes canning more than 100 pounds of ground beef across two days with a pair of All American units, which is exactly the workload this pot is sized for.
It also suits anyone tired of buying gaskets. The machined regulator weight gives repeatable pressure control, and the parts are interchangeable with smaller All American models, so one lid serves several pots in a two-canner setup.
Where the 941 falls short
It falls short for households canning fewer than about 20 jars a year, because the weight alone makes it a poor fit for a small kitchen. A second drawback is the lid: occasional vapor lock at zero pressure leaves it stuck, and owners resolve it by gently prying with a cloth-wrapped flat screwdriver.
The manual is also a genuine annoyance, spreading key instructions across many pages in a way reviewers describe as tedious to work through. Read it once fully before your first batch rather than during it.
2. Presto 01781 Pressure Canner and Cooker, 23 Qt
Presto 01781 23-Quart Pressure Canner and Cooker
23 quart capacity
Holds 26 half-pints, 20 pints or 7 quarts
12 pounds empty
Deluxe dial gauge
Pros
- Most reviewed canner here with over 20k ratings
- 12 pounds empty is easy to carry and clean
- Deluxe dial gauge covers the full pressure range
- Also a water bath canner and pressure cooker
- 12-year limited warranty
Cons
- Aluminum reacts with acidic foods on long cooks
- Rubber gasket needs replacing over the years
- No induction compatibility
If you want the safest first purchase, this is it. The Presto 01781 carries more than 20,000 ratings at 4.8 stars, so the failure modes are well documented, and the load is a clean 26 half-pints, 20 pints or 7 quart jars. That is a real batch of food, not a token load.
At 12 pounds empty, it is roughly a third of the weight of the All American 941, which changes how you work. You can pull it off the burner to a cooling surface, carry it to the counter for jar filling and put it back, and a single person can handle a full session without a second set of hands.
The deluxe dial gauge is the part experienced canners care about most here. It registers the complete range of processing pressures, which matters above about 1,000 feet of altitude where water boils cooler and processing times must be adjusted. Reviewers who used to run a dial gauge elsewhere rate this one as accurate and repeatable.
Warp-resistant heavy-gauge aluminum heats fast and evenly, and the pot doubles as a boiling-water canner for fruit, jams, jellies, pickles and salsa. A canning and cooking rack and a 76-page instruction and recipe book are included, which matters if this is your first season.
Who the 01781 suits best
It suits a family of four to six processing 20 to 40 jars a session, and it suits beginners who want the clearest gauge and the most instructions in the box. Owners who switched to it after years with another brand usually cite even heating and simple repeatable operation as the deciding factors.
It also works as a large-capacity pressure cooker, so the purchase covers weekday cooking as well as harvest weekend canning. That dual use is a large part of why this model has accumulated more reviews than anything else we tested.
Where the 01781 falls short
It falls short on induction cooktops, since plain aluminum will not heat on an induction surface. It also falls short for long acid-heavy cooks, because the aluminum body reacts with vinegar and tomatoes, and experienced canners move stainless-lined or smaller canners to short acid runs.
The rubber sealing ring is the other recurring weakness. It needs occasional replacement across the life of the unit, and the sealing rim wants a light coat of olive oil every few uses to keep the seal clean.
3. Presto 01784 Induction Compatible Pressure Canner, 23 Qt
Presto 01784 23-Quart Induction Compatible Pressure Canner
23 quart capacity
Holds 7 quarts, 20 pints or 26 half-pints
Induction compatible base
12.5 pounds empty
Pros
- Works on gas
- electric
- smooth-top and induction
- Stainless clad base heats more evenly than plain aluminum
- Lid arrow and rim arrow alignment makes locking easy
- Cover lock blocks opening until pressure drops
Cons
- Only the 15 lb regulator is included
- Only one rack ships in the box
- Aluminum body reacts with acidic foods
- May need factory gauge recalibration
This is the 23-quart can to buy if your kitchen runs on induction. A stainless steel-clad base layered over heavy-gauge aluminum is the only full-size induction-compatible pressure canner most owners could find, and the evenness of the clad base is the reason reviewers who switched report more consistent processing.
The capacity matches the 01781 exactly at 7 quart jars, 20 pints or 26 half-pints, so nothing is lost to get induction support. Several long-term owners report five years of consistent use and rely on the weighted regulator rather than the dial for pressure control.
The locking mechanism is unusually clear. You line up the lid arrow with the rim arrow, and the air vent and cover lock build pressure only when the lid is properly closed while preventing the lid from opening until pressure is safely reduced. For a first-time canner, that removes a real source of anxiety.
The included 15 pound weight doubles as a safety release if maximum pressure is exceeded. At 12.5 pounds empty, the pot is noticeably easier to handle than an All American of the same class, which matters on the second and third load of a long day.
Who the 01784 suits best
It suits households with an induction range or a smooth-top glass cooktop who have been stuck with the 01781 or an older aluminum pot. It also suits canners who want the weighted regulator approach, since owners commonly run 10 or 15 psi weights and check with a dial.
For anyone who wants a single pot for canning, pressure cooking and boiling-water processing, the dual stovetop compatibility and the 12-year limited warranty make this the most flexible unit in the group.
Where the 01784 falls short
The box is the weakness. It includes only the single 15 pound regulator, so processing at 5 or 10 psi means buying the Presto regulator 50332 separately, and only one rack is included, which caps your pint count unless you add a second canner plate.
Its aluminum body still reacts with highly acidic foods during long cooks, and depending on your region the gauge may need to be shipped back to the manufacturer for recalibration. Check that before you commit at a higher elevation.
4. T-fal 22-Quart Aluminum Pressure Canner
T-fal 22-Quart Aluminum Pressure Canner, 3 PSI Settings, Home Canning, Includes Racks & Canning Guide, Large Capacity, Pressure & Water Bath Canning for Vegetables, Meats, Seafood & Fruits, Silver
22 quart capacity
Holds 24 half-pints, 18 pints or 7 quarts
14.8 pounds empty
Three PSI regulator dial
Pros
- Two canning racks included for stacking jars
- Built-in dial with three PSI settings and no separate weight
- Locking lid with a beginner friendly release valve
- Handles both pressure and boiling-water canning
Cons
- Lowest star rating in the group at 4.4 out of 5
- Some owners report the gauge auto-vents before 15 psi
- Steam has leaked around the handle for some units
The T-fal 22-quart is the most polarizing canner here, and the split is useful information rather than a disqualification. It holds 24 half-pint jars, 18 pint jars, 16 wide-mouth pints or 7 quart jars per batch, and it is one of the few units that includes two racks so you can stack jars without buying anything extra.
Its regulator is a built-in dial with three PSI settings, which removes the whole category of weighted gauge mistakes. You turn to the pressure you need instead of fitting a weight and reading a needle, and the gauge is large and easy to read from standing height.
Most owners bought it as a first canner, followed the included step-by-step canning guide, and report that it is easy to learn and sealed every jar. The locking lid, steam release valve and sturdy handles all point the same way, toward a unit that teaches you the process instead of hiding it.
The negative cluster is narrow and specific. About 9 percent of ratings are one star, and those reviews concentrate on slow pressure build times, a gauge that sometimes does not move, and steam escaping around the handle that requires the gasket to be reseated and cleaned.
Who the T-fal suits best
It suits first-time canners who want racks and a regulator in the box, since both are the parts most competitors charge extra for. It also suits canners working in half-pints or wide-mouth pints, since 24 half-pints and 16 wide-mouth pints is the best stacking figure in this roundup.
For a household that wants one vessel to do pressure canning and boiling-water canning of high-acid fruit, the dual certification and the locking lid make it a straightforward all-rounder.
Where the T-fal falls short
The gauge is the weak point, and it is a safety-relevant one. Some owners report it auto-venting before reaching 15 psi, and a few units arrived with a defective gauge or a gasket too large for the lid, which is why we would test pressure with a separate gauge before trusting a full load of low-acid vegetables.
The one-year warranty is also the shortest in the group, and the aluminum body discolors with use and can etch from acidic cooks. If you can in tomatoes heavily, this is not the pot for you.
5. MIRRO 22 Qt Pressure Canner with 5, 10 and 15 PSI Regulators
MIRRO 22 Qt Aluminum Pressure Canner with 3 Regulators, 5, 10 & 15 PSI
22 quart capacity
Regulators for 5 10 and 15 psi included
13.7 pounds empty
Weighted gauge design
Pros
- All three regulators included in the box
- No dial to watch while you work
- Dual cool-touch handles on a loaded pot
- Heats quickly and holds temperature steadily
Cons
- No dial gauge to confirm pressure
- Regulator needs a firm two click push to seat
- Rust colored stain around the steam vent
The Mirro 22-quart is the cleanest weighted-gauge option in the lineup, and the reason is the box contents. All three regulators, calibrated at 5, 10 and 15 psi, are included, along with racks for stacked jar loading, so you are not hunting for parts during your first session.
With no dial to read, the whole pressure question reduces to watching a weight. Experienced canners on the Mirro tend to be the people who already decided they do not want an annual gauge test appointment, and a commenter on a canning forum told us a weighted gauge ended that anxiety entirely after their extension service closed.
Heat performance is the quiet strength. Owners report fast heat-up and steady temperature with very little burner adjustment, and long-time owners who bought it a second time describe even heating and a lid that locks correctly. At 13.7 pounds empty it is light enough to move from burner to counter once the vent is closed.
The dual cool-touch handles matter more than they sound. A 22-quart pot loaded with 7 quart jars is genuinely heavy and hot, and handles you can grip at full load are a real safety improvement during harvest weekend.
Who the Mirro suits best
It suits experienced canners who already know pressure canning and want a simple weighted system, and it suits anyone living above 1,000 feet who prefers a specific weight over dial reading. The 5 and 10 psi regulators cover the lower processing pressures that altitude-corrected times depend on.
It also suits a household that wants to can large batches of meat, poultry and seafood over long processing runs, since the supplied regulator set covers every pressure level those loads need without hunting for extra weights.
Where the Mirro falls short
You have no independent confirmation of pressure. With no dial gauge, a regulator that is out of calibration gives you no warning, so this is a design choice rather than a free upgrade, and it is a poor match for a nervous beginner.
Two smaller issues come up repeatedly. The regulator must be pushed firmly onto the stem with two distinct clicks to seat properly, and it leaves a rust-colored stain around the steam vent from first use onward. Some owners also report poor performance on glass cooktops and switched to gas.
6. Granite Ware Pressure Canner, Cooker and Steamer, 20 Quart
Granite Ware Pressure Canner/Cooker/Steamer, 20-Quart
20 quart capacity
Regulator set for 5 10 and 15 psi
10.5 pounds empty
Hard anodized body
Pros
- Hard anodized body resists rust and staining better than plain aluminum
- Lightest 20 quart canner here at 10.5 pounds
- Adjustable three piece regulator set
- Non-stick interior simplifies sticky stocks and beans
Cons
- 20 quarts is the smallest capacity in this roundup
- Anodized aluminum still etches with highly acidic foods
- Less review history than Presto or All American
The Granite Ware 20-quart is the one to look at if your canning year is tomato-heavy. Its hard-anodized body resists the rust, staining and pitting that plain aluminum suffers, and owners who preserve acidic vegetables specifically point to that interior finish as the reason they bought it.
At 10.5 pounds empty, it is the lightest canner of real size in this roundup, and the adjustable three-piece regulator set is calibrated at 5, 10 and 15 psi. The same vessel works as a pressure cooker and a steamer, so a single purchase covers three jobs.
The non-stick interior is more useful than it sounds for pressure canning. Stocks, beans and rendered meat leave a sticky residue that plain aluminum holds onto, and owners running broth batches report that clean-up is noticeably easier on the coated surface.
Capacity is where it loses. Twenty quarts is the smallest figure in this lineup, and that puts a real ceiling on a large-batch session. Where a 23-quart unit holds 20 pints, the geometry here gives you fewer jars per load and more batches per afternoon.
Who the Granite Ware suits best
It suits canners who work with acidic vegetables and fruit and want an interior that tolerates them, and it suits anyone who wants one pot to also handle pressure cooking and steaming. The light weight makes it a good fit for cooks who load and unload frequently.
It also suits a household of two or three that wants pressure canning capability without a 23-quart pot of dead weight, since this unit still processes a meaningful batch in a single load.
Where the Granite Ware falls short
It falls short for the exact use case in our title. If your goal is large batches, 20 quarts is the smallest capacity we tested, and the difference between 20 and 23 quarts shows up as extra batches and extra burn time over a season.
Hard anodized aluminum is more resistant than plain aluminum but not immune, and owners still note etching from tomato and vinegar. Its review base of about 800 ratings is also thinner than the Presto and All American units, so there is less long-term field history behind it.
7. WantJoin 23 Qt Aluminum Pressure Canner with Gauge
Wantjoin Aluminum Pressure Cooker 23Qt Pressure Canner, Pressure Pot with Pressure Control for Home Kitchen or Restraurant, Commercial Pressure Cooker with Gauge
23 quart capacity
Induction compatible composite base
13.3 pounds empty
Six safety valves
Pros
- 23 quart capacity at the lowest price in the group
- Thickened composite base works on gas and induction
- Six safety systems including a pressure limiting valve
- Uncoated food grade contact surface with no coating to flake
Cons
- No canning guide or USDA documentation in the listing
- Rack and jar accessories are not listed as included
- Listing copy focuses on cooking rather than canning
On raw size and price, the WantJoin 23-quart is hard to argue with. It is 23 quarts, it weighs roughly 13.3 pounds empty, and its thickened composite base works on both gas and induction, which normally costs a premium at this size. A storage bag is included, which is unusual for a pot this large.
The safety package is unusually extensive for the category. Six independent systems are listed, including an automatic lock, a check valve, a pressure limiting valve, a safety valve, an alarm valve and an anti-blocking cover, and the contact surface is uncoated food-grade aluminum that will not flake a coating into your jars.
Here is the honest problem. The listing describes steaming, stewing and faster cooking, and it does not present the unit as a USDA-recommended home canning vessel. There is no canning guide in the box, no canning racks listed as included, and no documentation of the processing times and pressure schedules that pressure canning requires.
That is a documentation gap rather than a proof of a defect, and it is exactly why this pick sits where it does in the ranking. A 4.3 star average with about 9 percent one-star ratings reflects a unit that is widely liked as a large pressure cooker and unproven as a canning vessel.
Who the WantJoin suits best
It suits a cook who wants a large induction-capable pressure pot for batch cooking, stocks and meal prep on a budget, and it suits a household that will follow an external USDA-tested processing guide rather than one shipped in the box. At 13.3 pounds it stays manageable for one person.
It also suits anyone who wants to can as a secondary activity on a large existing pot, since the 23-quart volume and the induction base cover the mechanical requirements, provided you source your own racks and follow tested process times.
Where the WantJoin falls short
It falls short on everything that makes a canner trustworthy, which is process documentation and included accessories. You supply the rack, the guide and the confidence, and that shifts risk onto you rather than the manufacturer.
It is also the second most polarizing unit here by one-star share, at about 9 percent. If pressure canning is the reason you are buying rather than a side benefit, a purpose-built canner with a USDA-documented procedure is the better spend.
8. HAWKINS Bigboy Aluminum Pressure Cooker, 22 Litres
Hawkins Bigboy Aluminum Pressure Cooker, 22 Litres
22 liter capacity
Marketed for 22 to 30 servings
21.3 pounds empty
Weighted regulators
Pros
- Marketed for 22 to 30 servings
- Elliptical lid tucks under the pot lip so it cannot blow off
- Reinforced fibreglass handles plus two lifting handles
- Five year warranty for material and workmanship
Cons
- The manufacturer states it does not make a pressure canner
- One reviewer measured the 15 psi weight releasing near 10 psi
- Not induction compatible
This unit is included because it appears constantly in large-batch searches, and you should know why we would not use it for canning. At least one buyer reports being told directly by the manufacturer that Hawkins does not make a pressure canner, which makes this a high-volume pressure cooker rather than a USDA canning vessel.
The engineering around the lid is genuinely clever. The elliptical lid sits underneath the upper lip of the pot, and owners credit that geometry with eliminating the chance of the lid blowing off, which is a failure mode that ruins a batch and burns a forearm.
Volume is the draw. It is marketed for 22 to 30 servings for hotels, restaurants, large families or caterers, and the tall narrow body fits four quart jars plus two rows of smaller jars, which is a different geometry from the wide 22-quart pots elsewhere in this roundup.
Build quality gets consistent praise, with owners reporting consistent function over years and a base thickness of 4.06 to 4.88 mm. The extra-strong reinforced fibreglass handles plus two lifting handles are sized for a genuinely full load.
Who the Hawkins suits best
It suits a household cooking for a large gathering, a community kitchen or a caterer who needs 22 to 30 servings of pressure-cooked food and is not preserving it. The five-year warranty for material and workmanship defects is also the second strongest here.
It suits anyone who wants a big pot that simply cannot blow its lid off, since the elliptical lid design is a real mechanical advantage over conventional clamped lids.
Where the Hawkins falls short
It falls short on the only thing that matters for this article. The 4.2 star average is the lowest in the group, and the most serious review we found installed a test gauge and measured the 15 PSI weight releasing at roughly 10 PSI and not reseating until 5 PSI, with the manufacturer reported as unresponsive.
There is also a capacity discrepancy worth knowing, since the 22-litre listing corresponds to an 18-litre actual capacity for at least one size variant, the pressure cap can leak and pop if left unattended, and the pot is not induction compatible. Cook in it with confidence. Do not can low-acid food in it.
Stovetop vs Electric Pressure Canners for Big Batches
A stovetop canner wins for large batches, and the reason is heat-up and cool-down time. Electric units with digital controls heat slowly, hold a fixed pressure that cannot be adjusted, and then take a long time to depressurize naturally. Over a session of six or more loads, that overhead adds up to hours.
The altitude problem is worse than the speed problem. A r/CanningRebels user reported that a digital electric canner ran a fixed 10 PSI that could not be adjusted, so at their elevation everything came out overcooked, with green beans turning soft and mushy. Above about 1,000 feet, processing times must be extended, and a unit that will not let you change pressure or hold a longer time is working against safe results.
Electric units do have real advantages indoors. You load the jars on a counter, press one button and walk away, which is easier on your back than standing over a burner, and a commenter on a canning forum shortened preheat time by filling the unit with hot water first. For a beginner canning 10 jars a year, that convenience is worth more than throughput.
For a harvest weekend, the arithmetic favors the stove. A 23-quart stovetop canner heats and pressurizes faster, runs a tested pressure schedule, and cools down on its own while you fill the next batch of jars, and that pipeline is why serious large-batch canners choose stovetop units even when an electric model is on the shelf.
Pressure Canner Buying Guide: What Actually Matters
Choose capacity by harvest size, not by wishful thinking
Count the jars you expect to process in a single session and match the canner to that number, not to the biggest number available. Households canning 20 to 40 jars a session are served by a 22 to 23-quart canner holding 7 quart jars or 18 to 20 pints per load.
Households putting up 60 or more jars a season should look at the 41.5-quart class, which handles roughly 19 quart jars or 32 pint jars at once. Households canning 10 or fewer jars a year will get the same food out of a smaller, cheaper pot and will thank themselves for not lifting 33 pounds of aluminum.
Experienced canners who hit their ceiling run two canners rather than one enormous pot. On survivalist forums, owners running a 21.5-quart and a 30-quart canner together report a combined 21 quarts or 38 pints, and the second pot lets one batch process while the other is being loaded.
Gasket or gasket-free
A gasket is a rubber or fiber sealing ring, and gasket-free designs use a machined metal-to-metal seal instead. The All American 941 in this roundup is gasket-free, which removes replacement cost and the most common reason a canner stops holding pressure.
Every other unit here uses a gasket that will eventually need replacing, and the reviews are consistent about the maintenance: grease the sealing rim lightly with olive oil every few uses, clean the ring, and store it flat so it does not take a set.
How to load a canner for the maximum number of jars
Start with the rack and set it in the center of the pot, then place quart jars around the outside with a jar of water in the middle so the center glass is not exposed to direct heat. Fill the gaps rather than guessing, because a loose layout is what leaves a quart of unused volume at the bottom of the pot.
For pints and half-pints, buy the second rack. Two rows of pint jars is the difference between 7 pints and 20 pints in the same 23-quart canner, and that is the single highest-value accessory in this entire roundup. One owner described loading a non-standard canner with 7 quarts on the bottom and 3 more on their side, which shows how much geometry matters and why you should not copy a jar count from a different pot.
Do you need a second canner?
If your harvest regularly outruns a single pot, a second canner beats a bigger pot for most people. Two units mean one load is processing while the other is being filled, which removes the dead time where a single large pot sits sealed and doing nothing but holding heat.
Two owners on r/Canning describe running a pair of All American units through more than 100 pounds of ground beef in two days, and survivalist forums report a 21.5-quart plus a 30-quart setup reaching 21 quarts or 38 pints in a combined session. Those are the throughput numbers a 100-jar day actually requires.
Dial gauge or weighted gauge
A dial gauge reads pressure on a needle and needs annual testing at a state extension service or an approved gauge test station. A weighted gauge, often called a jiggler, holds a set pressure and needs no test, but you choose the correct weight for your altitude and food.
Both systems are accepted for home canning. Experienced canners split along practical lines: those near an extension service keep a dial gauge and test it yearly, while those whose testing access closed or who want zero maintenance switch to a weighted gauge and stop thinking about calibration. The Mirro suits the second group best, because it ships with the 5, 10 and 15 pound regulators in the box, while the Presto 01784 includes only the 15 pound regulator.
What not to buy
Do not can in a household pressure cooker. USDA guidance is clear that electric pressure cookers are not reliable for canning, because they are designed to cycle and vent rather than to hold steady pressure for the 10 to 15 PSIG and 240 to 250F processing range that low-acid food requires.
Do not buy a canner without a way to confirm pressure, and be cautious with used units. A buyer on a canning forum picked up a used All American that felt like a bargain but warned that the gauge still needed testing, because most used listings say nothing about when the gauge was last verified.
When you inspect a used canner, check for cracks in the casting, any warping of the lid rim, rust pitting around the sealing surface, and a gauge with a test date. Missing gaskets, racks or manuals are minor. An unverified gauge is not, and it is the one thing that ends the conversation.
Frequently Asked Questions
How many jars will a 23 quart pressure canner hold?
A 23 quart pressure canner holds 7 quart jars, about 20 pint jars or about 26 half-pint jars per load. The pint and half-pint figures depend on rack layout, because the higher counts require a second rack and two rows of stacked jars. Jars should sit on a rack and should not touch each other or the canner wall.
What size pressure canner is best for large batch canning?
For most families, a 22 to 23 quart stovetop canner is the right size for large batches, holding 7 quart jars or 18 to 20 pints per load. If you process 60 or more jars of low-acid food a season, step up to a 41.5 quart canner such as the All American 941, which holds roughly 19 quart jars or 32 pint jars in one run.
Is there a pressure canner that does not require a gasket?
Yes. The All American 941 uses a precision machined metal-to-metal sealing system instead of a rubber gasket, so there is no sealing ring to replace, stretch or harden. Every other canner in our roundup uses a gasket that needs occasional replacement and a light coat of oil on the sealing rim every few uses.
Do pressure cookers count as pressure canners?
No. USDA guidance states that household electric pressure cookers are not reliable for canning because they vent and cycle rather than holding a steady 10 to 15 PSIG at 240 to 250F. That is also why some large pressure cookers marketed for batch cooking carry no USDA canning documentation, and why the Hawkins unit in our roundup is excluded from canning recommendations.
What are people saying about the Presto 23 quart pressure canner?
The Presto 01781 has more than 20,000 ratings averaging 4.8 stars, the largest review base in our roundup. Owners praise even heating, an accurate deluxe dial gauge, a 12 pound empty weight and a 12-year limited warranty. Recurring drawbacks are aluminum reacting with acid foods on long cooks, eventual gasket replacement, and no induction compatibility, which is why the induction-compatible 01784 exists.
Our Final Verdict for Large-Batch Canning in 2026
The All American 941 is our pick for the best pressure canner for large batches, because nothing else here processes 19 quart jars or 32 pint jars in one run, it needs no gasket, and it holds a 4.9 star average across nearly 9,800 ratings. The 33 pound empty weight is the trade you make, and it only makes sense if you actually have that many jars to put up.
For everyone else, the Presto 01781 is the safest first purchase and the one most people should end up with. It holds 7 quart jars or 20 pints, weighs 12 pounds empty, has the most reviews in the group and carries a 12-year limited warranty. Switch to the Presto 01784 if you cook on induction, and pick the Mirro 22-quart if you want a weighted system with no gauge to test.
Whichever you choose, match the capacity to the harvest, keep a tested processing schedule for your altitude, and never try to save time with a household pressure cooker. Those three habits are what make a large batch safe rather than merely fast.
