A pressure canner is the one piece of canning gear you can't improvise. Green beans, corn, potatoes, meat, stock: anything low in acid has to be processed at 240 to 250°F to deal with botulism spores, and boiling water tops out at 212°F at sea level. The only way to get there at home is steam under pressure, per the National Center for Home Food Preservation (NCHFP).
So the question isn't whether you need one if you want to can vegetables. It's which one fits your kitchen, your batch size and how much fiddling you're willing to do.
What actually matters
- Capacity. NCHFP's processes were developed for canners that hold at least 4 quart jars upright with the lid on. Anything smaller is a pressure cooker, not a canner, and USDA has no tested times for it. Most of the stovetop canners below hold 7 quarts.
- Dial gauge or weighted gauge. A dial gauge lets you use the finer pressure steps in USDA's altitude tables, but NCHFP says to have it checked for accuracy every year (many county Extension offices do this). A weighted gauge rocks or jiggles and never needs checking, but above 1,000 feet it runs at the next step up: 15 pounds instead of 10.
- Gasket or no gasket. Most modern canners seal with a gasket, which NCHFP says should be kept clean and checked for nicks or drying. All American's canners use a metal-to-metal seal with clamping locks instead, per the listing.
- Your cooktop. Check the listing. Presto says the 01781 works on regular and smooth-top ranges. T-fal lists gas and electric coil cooktops.
Presto 01781: the straightforward 23-quart
This one keeps things simple. It's big enough for 7 quarts or 20 pints per load, it reads pressure on a dial, and it doubles as a boiling-water canner for jams and pickles, per Presto. It also carries a 12-year limited warranty. The trade-off is the dial gauge: plan on getting it tested each season.
Presto 01781 23-Quart Pressure Canner and Cooker
- Holds 26 half-pints, 20 pints or 7 quarts, per the listing
- Dial pressure gauge
- Heavy-gauge aluminum; works on regular and smooth-top ranges
- Doubles as a boiling-water canner; rack and 76-page instruction and recipe book included; 12-year limited warranty
Cooking on induction? Presto makes an induction-compatible version, the 01784, a 23-quart heavy-gauge aluminum canner with a stainless-clad induction base. The listing says it works on induction, gas, electric and smooth-top ranges, and it carries the same 12-year limited warranty.
Presto 01784 23-Quart Induction-Compatible Pressure Canner
- Works on induction, gas, electric and smooth-top ranges, per the listing
- Heavy-gauge aluminum with a stainless-clad induction base
- Pressure gauge; air vent/cover lock
- Doubles as a boiling-water canner; 12-year limited warranty
All American 1930 canners: no gasket, made in the USA
All American's canners are built around one idea: no gasket to wear out. Clamping locks squeeze a metal-to-metal seal, and each model has both a steam gauge and a regulator weight, per the listing. They come in several sizes. The 921 is the one to pick if you want the same 7-quart capacity as the big Presto, with room for about 19 pints.
All American 1930 921 Pressure Cooker/Canner, 21.5 Quart
- Holds about 19 pint jars or 7 quart jars, per the listing
- Metal-to-metal seal with clamping locks; no gasket
- Steam gauge plus a machined regulator weight
- Made in the USA
Smaller kitchen or smaller batches? The 915 holds about 7 quarts or 10 pints, and the 910 holds about 4 quarts, per All American. Remember NCHFP's 4-quart minimum: the 910 sits right at it.
All American 1930 915 Pressure Cooker/Canner, 15.5 Quart
- Holds about 10 pint jars or 7 quart jars, per the listing
- Metal-to-metal seal with clamping locks; no gasket
- Steam gauge plus a machined regulator weight
- Made in the USA
All American 1930 910 Pressure Cooker/Canner, 10.5 Quart
- Holds about 7 pint jars or 4 quart jars, per the listing
- Metal-to-metal seal with clamping locks; no gasket
- Steam gauge plus a machined regulator weight
- Made in the USA
Granite Ware 20-Quart: a three-step pressure regulator
Granite Ware's canner uses an adjustable 3-piece regulator calibrated at 5, 10 and 15 psi, per the listing, and it's made of hard-anodized aluminum. That lines up with how USDA tables are written for weighted-gauge canners (10 pounds at low altitude, 15 above 1,000 feet), but check the manual for how its regulator should be used, and check the listing that it holds at least 4 quart jars, NCHFP's minimum for USDA processes.
Granite Ware 20-Quart Pressure Canner/Cooker/Steamer
- Hard-anodized aluminum, per the listing
- Adjustable 3-piece pressure regulator calibrated at 5, 10 and 15 psi, per the listing
T-fal 22-Quart: two racks for stacking pints
T-fal's canner comes with two racks, so you can double-stack smaller jars. The listing puts it at 24 half-pints, 18 regular pints, 16 wide-mouth pints or 7 quarts, with three pressure settings. It's listed for gas and electric coil cooktops, so check before buying if you have glass.
T-fal 22-Quart Aluminum Pressure Canner
- Holds up to 24 half-pints, 18 pints, 16 wide-mouth pints or 7 quarts, per the listing
- Three pressure (PSI) settings, per the title
- Two canning racks and a step-by-step canning guide included
- For gas and electric coil cooktops; one-year warranty
Presto digital canners: push-button, with a caveat
Presto's digital canners automate pressure canning and water bath canning on the countertop, and Presto says they need no adjustment for altitude, and the listing says a sensor holds the processing temperature. That's genuinely convenient. The caveat: in a 2021 statement relayed by Kansas State Extension, NCHFP said the University of Georgia hadn't independently verified Presto's marketing claims, that Presto did its own research, and that you should follow Presto's manual and recipes with these units rather than USDA/NCHFP directions.
Presto 02144 12-Quart Digital Pressure Canner
- Electric canner that automates pressure canning and water bath canning, per Presto
- Presto says no adjustments are needed for high altitude
- Sensor holds the processing temperature; ten built-in safety features, per the listing
- LED display walks through each stage
Presto 02152 17-Quart Digital Pressure Canner
- Extra-tall version that holds quart jars, per the listing
- Pressure canning and boiling-water canning
- Presto says no altitude adjustments are required
- Control knob for method and time; LED display

Using any stovetop canner safely
The canner is only half of it. These steps come straight from NCHFP and apply to every brand:
- Vent first. Once steam pours out of the open vent, let it go for a full 10 minutes before you close the petcock or put the weight on. Trapped air means the temperature inside is lower than the gauge suggests.
- Time from pressure. Start the clock when the dial reads the target pressure or the weight starts to jiggle. If pressure drops below target, bring it back up and start the time over.
- Let it come down on its own. No cold water, no opening the vent early. NCHFP warns forced cooling can lead to unsafe food and seal failures.
- Wait 10 more minutes. After it's depressurized, remove the weight or open the petcock, wait 10 minutes, then lift the lid away from your face.
- Use tested times for your altitude. Every USDA recipe lists times and pressures by elevation.
FAQ
Can I use an Instant Pot as a pressure canner?
No. NCHFP doesn't support using USDA canning processes in electric multicookers, even with a canning button. The tested processes were developed for stovetop canners that hold at least 4 quart jars.
Do I need a pressure canner for green beans?
Yes. They're low-acid, and NCHFP says flatly that there's no safe boiling-water option for green beans. See our green bean guide.
How often should a dial gauge be checked?
Every year before canning season, per NCHFP. If it reads more than 2 pounds off, replace it.
