Canning Pot vs Stock Pot: Can You Use a Stock Pot?
You do not necessarily need to buy a dedicated canner to start water-bath canning, a big stock pot can work. But there are two requirements a pot must meet, and understanding them helps you decide whether to buy a canner or use what you have.
How they differ
A canning pot is purpose-built: it includes a rack and has the depth to cover jars with an inch or more of boiling water. A stock pot can substitute if it meets the same two needs, tall enough to submerge the jars, and fitted with a rack so jars sit off the bottom. Many kitchens already own a suitable large stock pot.
| Canning pot | Stock pot | |
|---|---|---|
| Rack included | Yes | Add your own |
| Depth for jars | Designed for it | Must be tall enough |
| Best for | Regular canning | Occasional, if suitable |
When a stock pot works
Use a stock pot if it is deep enough to cover your jars by an inch-plus and you add a rack (a canning rack, or even extra jar rings or a folded towel in a pinch) to lift jars off the bottom. For occasional small-batch canning of jams or pickles, this is a perfectly good start. See how to make jam for canning.
When to buy a canner
Buy a dedicated canner if you can regularly or in larger batches, the built-in rack, correct depth and jar capacity make the job easier and more reliable. See the best water-bath canning kit and, for size, 21 vs 33 quart.
The verdict
Occasional canning with a tall stock pot? Add a rack and it works for high-acid foods. Canning regularly? A dedicated canner is more convenient and reliable. Learn the method in how to water-bath can.

Frequently asked questions
Can I use a stock pot for water-bath canning?
Yes, if it is deep enough to cover the jars by at least an inch of water and you add a rack to keep jars off the direct heat of the bottom. A dedicated canner just makes it easier.
What makes a pot suitable for canning?
Enough depth to submerge jars with headroom for a rolling boil, and a rack so jars do not sit on the bottom. Canning pots include both; a tall stock pot needs a rack added.
Do I need a canning rack?
Yes, jars must not sit directly on the pot bottom, where heat is uneven and jars can crack. A canning rack (or even a folded towel or extra rings in a pinch) keeps them lifted.
