A canning pot has one job: keep jars covered with boiling water for the full processing time. That makes depth the spec that matters most. The National Center for Home Food Preservation (NCHFP) says a boiling water canner must keep at least 1 inch of vigorously boiling water over the jars, and 2 inches if the process runs longer than 30 minutes. It also needs a rack and a fitted lid.
After depth, it's about your stove. Classic enamel canners are cheap and light but are designed for gas and coil burners. Glass tops and induction ranges need a flat-bottomed stainless pot.
A canning pot is for acid foods only: fruit, jam, jelly, pickles and acidified tomatoes. Vegetables, beans and meat must be pressure canned, as our pressure canning vs water bath canning guide explains. Below are six pots worth buying, with specs from the makers' own pages and listings.

The Best Canning Pots, Reviewed
1. Granite Ware 21.5-Quart Canner with Jar Rack (Best Budget)
Who it's for: anyone with a gas or coil-electric stove who wants the classic canner at the lowest cost.
This is the speckled black enamel pot most people picture when they think of canning. It holds 7 quart jars, 9 pints or 12 half-pints in the included jar rack. Granite Ware's maker, Cinsa, lists it as enameled steel, made in Mexico, with a two-year warranty.
The catch is the bottom. Granite Ware's usage guide says not to use its enamel canners on glass cooktops; they're for gas and electric stoves. Enamel can also chip if you knock it, so handle it gently and dry it after use.
Pros
- Lowest cost of entry for a full-size canner
- 7-quart, 9-pint or 12-half-pint rack included
- Simple, proven design
Cons
- Not for glass cooktops or induction
- Enamel can chip
- Short two-year warranty

2. McSunley Prep-N-Cook 21.5-Quart Stainless Steel Water Bath Canner (Best Stainless Steel)
Who it's for: glass-top and induction cooks who want a dedicated stainless steel canning pot.
McSunley says its water bath canner works on all cooktops, including induction and glass-top ranges, thanks to a flat, encapsulated base. It's heavy-duty stainless steel, and the stainless jar rack rests on the pot's sides and holds 7 quarts, 9 pints or 12 half-pints, the same counts as the Granite Ware. McSunley lists the pot at 9.5 inches tall and 8.9 lb.
That height is worth checking against your jars. The NCHFP's 1- to 2-inch water rule means you need to measure your quart jars on the rack before committing to long processes. McSunley doesn't publish a warranty on its product page; one retailer lists a 10-year warranty, but we couldn't confirm it with the maker.
Pros
- Works on glass tops and induction, per McSunley
- Stainless body and rack won't chip or rust like enamel
- Same 7/9/12 capacity as the classic canners
Cons
- Costs more than enamel
- Weighs 8.9 lb empty
- Warranty not stated by the maker

3. Kitchen Crop Harvest Stainless Steel Multi-Use Canner VKP1130 (Best 2-in-1)
Who it's for: people who want the option of steam canning without buying a second pot.
This 20-quart pot comes with a double-sided stainless rack. Flip it one way for water bath canning and the other for steam canning. Kitchen Crop (the VKP/Victorio brand) says it holds 8 pints or 7 quarts and has an 18/8 stainless pot with a flat clad bottom for any cooktop, including induction. The tempered glass lid has a built-in temperature indicator, and Kitchen Crop backs it with a five-year warranty. The pot is 15½ inches across and 9½ inches tall.
Steam canning saves water and heat-up time, but it has strict limits: acid foods only and a total process of 45 minutes or less, per University of Wisconsin research the NCHFP endorses. Our steam canner guide covers those rules and which steam canner designs were actually tested.
Pros
- Steam or water bath in one pot
- Works on induction and glass tops
- Temperature indicator in the lid
- Five-year warranty
Cons
- Only 8 pints per load
- Steam method has a 45-minute cap
- Steam-mode rules take some learning

4. Ball EasyCanner Electric Water Bath Canner, 21 Qt (Best Electric)
Who it's for: people who'd rather not tie up a burner or babysit a boil, and anyone whose cooktop can't handle a canner.
Ball's electric canner holds up to 7 quart jars or 8 pint jars and runs at 1,400 watts. Its "Press & Forget" programming automates preheating and processing, with heat sensors to hold temperature. An exterior drain spout lets you empty the water into the sink instead of lifting a full pot. It also works as a multi-cooker for pasta, soups and steaming. The stainless pot is hand wash only, but the lid, rack and steam tray are dishwasher safe. It measures about 16.85 inches square and 14.88 inches tall.
You still need tested recipes and their times. Read the manual for how it handles altitude adjustments before you use it above 1,000 feet. And like every canner on this list, it's for acid foods only.
Pros
- Frees up the stovetop
- Automated heat-up and timing
- Drain spout for easy emptying
- Doubles as a multi-cooker
Cons
- Takes counter and storage space
- Pot is hand wash only
- Premium price for a water bath canner

5. Presto 01781 23-Quart Pressure Canner and Cooker (Best Pot That Also Pressure Cans)
Who it's for: anyone who expects to can vegetables, beans or meat eventually and only wants to store one big pot.
The 01781 is a pressure canner first, but Presto designs it to double as a boiling water canner, and it's tall enough for quart jars. In water bath mode, you follow Presto's boiling water directions, which keep the canner from building pressure. When you're ready for green beans or chicken, it holds 7 quarts or 20 stacked pints under pressure. Our best pressure canner guide covers the pressure side in depth.
It isn't the obvious pick if you'll only ever make jam. It costs more than a basic enamel canner and has a gasket that Presto says to replace every two to three years.
Pros
- One pot for water bath and pressure canning
- Tall enough for quart jars in boiling water mode
- 12-year limited warranty from Presto
Cons
- Costs more than a water-bath-only pot
- Sealing ring needs periodic replacement
- Not induction compatible (the 01784 version is)

6. Norpro 658 Krona Stainless Steel 20-Quart Stockpot (Best Everyday Stockpot)
Who it's for: cooks who want one big pot for stock, corn and pasta that can also run a canning batch.
Norpro sells this 20-quart stainless stockpot as a water bath canner as well as a stockpot, with a tri-ply encapsulated base (aluminum between two stainless layers), a solid stainless lid and stay-cool handles. It doesn't come with a rack, so pair it with a Norpro rack. Norpro says its 646 small rack fits, and its 604 full-size rack lists the 658 among the pots it fits. Our canning rack guide compares both. Norpro sells the 658 through kitchen retailers, and we couldn't find a current Amazon listing for it. If you're shopping on Amazon, the McSunley 21.5-quart stainless canner above is the closest stainless alternative, and it comes with a rack.
Norpro doesn't state cooktop compatibility for this pot, so check with Norpro before using it on induction. It also weighs 9.35 lb empty and should be hand washed.
Pros
- A pot you'll use all year, not just in canning season
- Tri-ply encapsulated base
- Pairs with Norpro's canning racks
Cons
- Rack sold separately
- Induction compatibility not stated
- Weighs 9.35 lb empty
- No Amazon listing found

Canning Pot Buying Guide
Depth comes first
Use the NCHFP rule: at least 1 inch of boiling water over the jars, 2 inches for processes longer than 30 minutes, plus extra room so the pot doesn't boil over. A quart jar on a rack needs a deep pot. If you mostly can pints and half-pints, a shallower pot will do.
A rack is not optional
The NCHFP says a boiling water canner needs a removable, perforated rack. The rack keeps jars off the hot bottom and lets water circulate. A canning pot with a rack is the simplest option. If you're converting a stockpot, see our canning rack picks.
Match the pot to your cooktop
- Gas: flat or ridged bottoms both work, per the NCHFP.
- Electric coil or smooth top: the NCHFP says to use a flat-bottomed canner, no more than 4 inches wider than the burner.
- Glass top: use a flat-bottomed stainless pot and confirm with your range manual. Granite Ware says its enamel canners shouldn't be used on glass.
- Induction: you need a magnetic stainless base. McSunley and Kitchen Crop say their stainless canners work on induction.
Enamel vs stainless steel
Enamel-on-steel is the budget option. It can chip, and the classic designs aren't for glass tops. Stainless costs more and weighs more, but a flat, clad or encapsulated base gives you glass-top and induction options and a pot that lasts.
Capacity
The standard is 20 to 21.5 quarts, enough for 7 quart jars, the usual full load. Bigger isn't better here. A larger pot takes longer to boil and is harder to lift.
Stovetop, electric or steam
An electric water bath canner frees up the stove. A steam canner uses far less water but is limited to acid foods with processes of 45 minutes or less. A pressure canner that doubles as a water bath canner saves storage space if you'll pressure can too.
How to Use a Canning Pot (NCHFP Basics)
- Put the rack in the pot and add water. Preheat it to about 140°F (60°C) for raw-packed foods or 180°F (82°C) for hot-packed foods.
- Load filled jars upright with a jar lifter. Add boiling water if needed to cover the jars by 1 inch (2 inches for processes over 30 minutes).
- Turn the heat to high, cover and bring to a vigorous boil.
- Start timing at a full boil and keep it boiling the whole time. If the boil stops, bring it back and restart the full time.
- When time is up, turn off the heat and wait 5 minutes.
- Lift the jars out upright and cool them undisturbed for 12 to 24 hours.
Times come from tested recipes and go up with elevation above 1,000 feet. Our canning supplies guide lists the tools you'll want alongside the pot.
How We Chose
We didn't test these pots in a kitchen. We chose them by research: product pages and specs from Granite Ware's maker Cinsa, McSunley, Kitchen Crop, Ball, Presto and Norpro, plus retailer listings where a maker's page left gaps. We weighed them against NCHFP guidance on canner depth, racks and cooktop fit. We also considered university extension advice and patterns in owner feedback. We left out pots whose jar capacity we couldn't confirm.
FAQ
How deep does a water bath canning pot need to be?
Deep enough to keep at least 1 inch of vigorously boiling water over the jar tops, per the NCHFP, and 2 inches if the process runs longer than 30 minutes. Measure your tallest jar on the rack and add that water depth plus room to boil without spilling over.
Can I use a regular stockpot as a canning pot?
Yes, if it is deep enough and you add a rack. The NCHFP says a boiling water canner needs a rack and a fitted lid, plus enough depth for 1 to 2 inches of water over the jars. Jars should never sit directly on the pot bottom.
Can you water bath can on a glass-top stove?
Often, with the right pot. Use a flat-bottomed canner, and on electric ranges the NCHFP says its diameter should be no more than 4 inches wider than the burner. Granite Ware says not to use its enamel canners on glass cooktops. Check your range manual too.
Is stainless steel or enamel better for a canning pot?
Enamel-on-steel canners are inexpensive but usually have ridged bottoms meant for gas and coil burners. Stainless canners with flat, clad or encapsulated bases cost more and work on glass tops and, in many cases, induction.
Can I use a canning pot for low-acid foods like green beans?
No. A boiling water canner can't get above 212°F. The USDA Complete Guide to Home Canning says low-acid foods such as vegetables, meat and beans must be processed in a pressure canner.
What size canning pot do I need?
A 20- to 21.5-quart pot with a rack is the standard size. It holds 7 quart jars, the usual full canner load, plus 8 or 9 pints depending on the rack.
Verdict
On a gas or coil stove, the Granite Ware 21.5-quart is still the best canning pot for the money. On a glass top or induction range, get the McSunley Prep-N-Cook stainless canner. If you want the option of steam canning, the Kitchen Crop Harvest does both, and if you'll pressure can later, the Presto 01781 covers both methods in one pot.
