Canning pumpkin in the pressure canner makes it safe to store and quick to use later in pumpkin butter, pies, muffins, or other pumpkin recipes.
I get questions on how to can pumpkin puree or pumpkin butter. My best advice is to can it in cubes. Puree it when you want to use it in your recipes. Easy! And more importantly, it’s safe too.

The procedure for canning pumpkin is actually very straightforward. Seed it, skin it, cube it up, and place the cubes in jars. Honestly, the cutting up and prep is the hardest part. Watch those fingers and sharp knives? Pumpkins tend to roll.
How to Peel a Pumpkin (without chopping off your fingers!)
The first step is seeding the pumpkin. Your best bet is to chop off the top of your pumpkin, removing the stem and top portion. Slice down the center to cut the pumpkin in half. This gives you better access to the seeds and strings. You are not carving this for your step so just open it up and get to the seeds. Then use a large spoon to scoop out the seeds. Save them for roasting or replanting in the spring if you have heirloom pumpkins.
Next, you need topeel the pumpkin. This is where it gets tricky. I tried several things. A regular vegetable peeler was useless, as the rind is far too tough. I tried using a knife to peel the rind of each half. This was awkward. I had sharp knives slipping, and I was destined to chop off a finger. I knew I had to find a better way or I’d be there for HOURS (not to mention ending up fingertipless)!
Finally, I found the best way was to slice my pumpkin into strips.
Then use a knife to slice off the rind. This was much more manageable. The pumpkin did not roll around on me. I was able to slice down into my butcher block and my fingers were safe!
I was still there quite a while slicing and peeling pumpkin, but it worked.

Peeling pumpkin tips from readers.
Al suggests: There is only one thing I would suggest. For those who have bad wrists, I would use an electric knife for cutting the rind.
Michele adds: I found if I put the pumpkin cut in half in the oven for 1 hour on 350 it softens them enough so I can peel them. I have carpal tunnel & had to learn a new way to deal with heavy rind squashes… I do this with the huge pumpkins & add just enough water to fill the bottom of the pot & then put foil over the top so the steam helps soften them.
They are then cooled a bit & I can cut them up & put in the jars adding more hot water to fill the canning jar, no extra cooking/blanching needed. They will be a bit softer in the jars but don’t turn to mush so this might help someone who has troubles with bad wrist.
Sharon’s reply: I did try this too, but I didn’t care for the pumpkin being so soft to start out. But it is most certainly an option.
Fill your canning jars:
Next you need to cut your pumpkin into about 1-inch cubes. (Remember, no pureeing!)
Place in a large stock pot. Add water and bring to a boil. Boil 2 minutes. You don’t need to cook thoroughly, just 2 minutes. This will warm the pumpkin up. Pumpkin must be a hot pack. Do not put raw cubes in your jar. Next fill your hot jars leaving a 1 inch headspace.
Using a slotted spoon, I scooped out the pumpkin and placed in jars. If you want salt, add 1 teaspoon per quart or 1/2 tsp per pint. Then fill each jar with the cooking water, leaving 1-inch headspace.
Using a plastic spatula or other small tool, release any air bubbles. There is a tool you can buy for this step, but I find my orange peeler works perfectly.
Wipe the rims of your jar clean so there are no food particles to interfere with the seal. Place your canning lids. Here I was using traditional metal lids that I needed to use up.
Place your jars in your preheated canner and process as directed below. For more information on how to use your pressure canner, click here.

Tips and Frequently Asked Questions.
Canning Winter Squash?
Winter squash is canned the same as pumpkin, so you’re also in the right place if you’re learning how to can winter squash!
Can you can pumpkin puree?
When you are canning pumpkin or any other winter squash you must can it in cubes. You should not puree it, then try to preserve it in jars. The concern with pureeing it is that the density of the puree will be thick. The heat achieved in the pressure canner must reach all the way to the center of your jars. If your pumpkin is cubed, the heat will penetrate much better. Cubed is safer and is the only way this process has been tested. I recommend that you do NOT follow online instruction you may find for how to can pumpkin puree.
Pureeing Pumpkin when You Open the Jar.
If you need a pumpkin puree, mash it up when you open the jar. You will need to drain the pumpkin very well. I’ve found even then it will be thinner than commercially canned pumpkin. If you are using it for a soup base, you can just puree it with the liquid from your jar. It all depends on what you are making. It will not get thick like fresh pumpkin, but it works.
Should You Can Pumpkin in a Water Bath Canner?
Pumpkin is a low-acid food, so it MUST be processed in a pressure canner. There is no way around those recommendations. (Except, of course, to ignore them…which I don’t suggest.) I do not teach how to can pumpkin in a water bath.
Can I use my fall decoration pumpkin for canning?
Yes, you can as long as you have not carved them and left them on your step for a few weeks. If these are your carved pumpkins do not preserve them. (they make great chicken or goat treats!) These pumpkins may not have as sweet a flavor as say a small pie pumpkin, but they work just great. I’ve canned them before. Just be sure you are using a fresh pumpkin.
