Pressure canning is my absolute favorite food preservation method. It’s really easy, and an almost foolproof way to make food shelf stable for years. Living off grid, freezer space is at a premium and while freezing green beans is a great way to preserve them, a single power outage will completely wipe out your stores.
For some reason pressure canning raises eye brows and causes fear in novice canners. Everyone I talk to seems terrified that the thing is going to blow up. At the same time, the instant pot has snuck into just about every suburban kitchen and is all the rage for cooking quick weeknight meals. News flash: it’s a pressure cooker. See, not scary at all.
For pressure canning, you’ll need something a bit more industrial than an instant pot. I use a 30 quart All American Pressure Canner because it’s simple to use, has no disposable parts and has a high capacity. In hindsight, I wish I’d splurged and bought the 41.5 quart model because we do a lot of canning and that added capacity would save a so much time.
Start by preparing your green beans. Wash them, remove the tips and cut into bite sized pieces. Pack into jars, leaving at least 1 inch of headspace. There’s no need to pre-cook the beans, as they’ll be more than cooked in the pressure canner. Skip sterilizing the jars too. Jar sterilization isn’t required for pressure canning, just wash them to make sure they’re clean and you’re golden.
Green Beans Chopped for Canning
Add in 1/2 tsp sea salt for pint jars, or 1 tsp for quarts. Feel free to use less, but I wouldn’t recommend using less than half that amount. While salt is not necessary for preservation, it is necessary for flavor, and without the salt they taste like almost nothing.
Cover the beans with boiling water, leaving 1 inch of headspace. Put on lids and rings, tightening the rings to finger tight. Be sure to use new canning lids each time, but canning rings can be reused. Since new canning lids are needed each time you can, we buy ours by the case and save a lot of money each year. They don’t go bad, so it makes sense to plan ahead.
Add 2-3 inches of water boiling water to the bottom of your pressure canner and add in the canning rack to the bottom (never can directly on the bottom of the canner with a rack). Place your jars in the canner, and make sure to use a dividing rack if you’re canner is a double decker model like the high capacity 30 quart and 41.5 quart models. Seal the canner by tightening down the nuts, and allow the canner to steam off for 10 minutes. This is an important step, because it ensures that the canner is completely full of steam before the weighted valve is added.
Add the pressure weight to the canner, and process at 10 pounds pressure (adjusting for altitude) for 20 minutes for pints and 25 minutes for quarts. Allow the pressure canner to cool and come back to zero pounds of pressure before removing the weight and allowing the last nub of pressure to escape. Loosen the nuts and open the top of the canner, and take out your freshly canned goods. Allow a few hours for the jars to cool, and make sure they’ve all popped and are sealed.
Remove the bands for storage once the jars are cool. Leaving the bands on can cause them to rust shut, which will leave you frustrated and hungry for food that you cant open. The jars are vacuum sealed, so the bands aren’t necessary at this point to hold the lids in place.
JUST GETTING STARTED CANNING?
If you’re just getting started canning, but plan on making canning and preserving food part of your lifestyle long term, try investing in an online canning course. Pioneering today has a canning with confidencecourse that takes you through the ins and outs of canning from basic canning safety all the way through to pressure canning meat at home. The course covers:
- Canning Safety – Safe techniques to for home canning
- Water Bath Canning – Jams, jellies, pickles, tomatoes, and other high acid fruits and vegetables including low sugar, no pectin variations.
- Pressure Canning – How to safely operate a pressure canner at home to can almost any type of food for long term preservation
- Troubleshooting and Storage – Figuring out why a recipe just didn’t work, and maximizing storage of your home canned goods.

I refuse to add any salt although the jars do get a slice of home grown onion on the top. I might lightly salt when heating them up to eat.
Ashley Adamant
That’s always an option, it’s all personal preference. The salt is not required for preservation, so either way is totally fine.

When I first took the beans/jars out of the pressure cooker the beans had risen to the top and there is about an inch of water at the bottom of the jar. Also there were a lot of bubbles. I did slide the tool around prior to sealing to get the air out. What’s up?
Ashley Adamant
With raw pack, the green beans do float to the top of the jar, that’s totally normal. They still have a small amount of air in their tissues after cooking so they float. If you don’t want them to float, they have to be hot packed. Hot pack is trickier to pack the jars, and involves extra cooking for the beans which they don’t really need.

can you add garlic to them?
Ashley Adamant
Whole garlic cloves aren’t approved for canning (other than as pickled garlic). In theory, if you were going to can garlic, I’d guess processing times would be similar to those for onions, which is 40 minutes. That’s much longer than these green beans can handle in a pressure canner.
The short answer, nope.

How many green beans do you get into a quart jar, I have read a few places that people fill the jar with approximately 2 pounds of green beans, but I can only get about 1 pound into the jar. Am I doing something wrong?
Ashley Adamant
You know, I’ll have to measure next time. I don’t think you’re doing anything wrong, I’ve often found that the extension guides on how much produce goes into a jar are a bit off.

You mentioned that you order bulk canning lids – I’ve had marvellous success with the ones from Dutchman’s Store in Iowa (info@dutchmansstore.com). They sell the lids in long sleeves, packed in lots of 345 regular mouth or 288 wide mouth for around $50/lot. If you e-mail or call them (319-397-2322), they’ll ship them through the regular mail within a few days of ordering.

I’m confused with this following sentence in your instructions on how to can green beans:
“”Seal the canner by tightening down the nuts, and allow the canner to steam off for 10 minutes. This is an important step, because it ensures that the canner is completely full of steam before the weighted valve is added.”
How would the canner stay full of steam if I am to “steam off” for ten minutes? Can you clarify, please?
Ashley Adamant
So that’s a normal part of pressure canning, and it’s not just for this recipe. It ensures that the chamber is completely full of steam, as the temp inside sometimes drops when you add the jars. Mine actually usually takes several minutes to start releasing steam after I close it.
The manufacturer of the All American Canner (with a weighted gauge) suggests letting steam escape the valve for 10 minutes before adding the weight and allowing it to come up to pressure. Not doing this step risks uneven heating in the chamber. I’ve never forgotten to do this, so I’ve never actually experienced the consequences…but from what I’ve read it can cause jars to either explode in the canner or fail to seal, depending on how the uneven heating goes in there.
Check your pressure canner manual, and follow the instructions it provides as you may have a different model, but I believe this is standard on all models.

its been maybe 30 years since I’ve done any canning. when we first moved to the country we went all in, then life happens etc etc. Times have changed in the last couple month. Luckily my husband retired recently and started gardening again. A very large garden with the tractor. I dug out my large, trusty, double canner. thank you for such clear instructions and explanations as to how and why canning is done the way it is. awesome refresher course! All the best to you and your family!

Are the newer versions of the Instant Pot acceptable for canning green beans?
Ashley Adamant
To the best of my knowledge, there are no instant pot versions that are approved for canning. Their settings don’t maintain a consistent pressure, at least not consistent enough for canning.
