Why You Should Can Pumpkin Puree at Home

There are so many reasons to can pumpkin puree at home instead of buying it from the store.
 
When you can pumpkin puree yourself, you control exactly what goes into it.
 
No mystery additives, no preservatives, and no unnecessary sugars.
 
Plus, if you’re growing pumpkins in your garden, canning pumpkin puree is a fantastic way to preserve your harvest without wasting a single thing.
 
Home-canned pumpkin puree also tastes fresher and richer than most store-bought versions.
 
And honestly, there’s something really satisfying about pulling a jar of your own pumpkin puree off the shelf in the middle of winter.
 

Choosing the Right Pumpkins for Canning Pumpkin Puree

Not all pumpkins are created equal when it comes to canning pumpkin puree.
 
You want to use sugar pumpkins or pie pumpkins, which are smaller, sweeter, and less stringy than the big carving pumpkins.
 
Carving pumpkins are watery and bland, so they don’t make great pumpkin puree for canning.
 
Look for pumpkins that are firm, heavy for their size, and free of soft spots or bruises.
 
Smaller pumpkins, usually around 4 to 8 pounds, are ideal because they have denser flesh and better flavor.
 
If you’re buying from a store, ask if they have pie pumpkins specifically for cooking and canning pumpkin puree.
 

How to Prepare Pumpkin Puree for Canning

Before you can pumpkin puree, you first need to make the puree itself.
 
Start by washing your pumpkins thoroughly to remove any dirt or debris.
 
Then cut each pumpkin in half and scoop out the seeds and stringy pulp.
 
Save those seeds if you want to roast them later.
 
Place the pumpkin halves cut-side down on a baking sheet lined with parchment paper.
 
Roast them at 350°F for about 45 to 60 minutes, or until the flesh is tender and easily pierced with a fork.
 
Once they’re cool enough to handle, scoop the flesh out of the skin and blend it until smooth.
 
You can use a food processor, blender, or even a potato masher if you like a chunkier texture, though smooth is better for canning pumpkin puree.
 
Now your pumpkin puree is ready for the canning process.
 

Steps for Canning Pumpkin Puree Safely

Canning pumpkin puree requires a pressure canner because pumpkin is a low-acid food.
 
A water bath canner simply won’t get hot enough to kill harmful bacteria like botulism spores.
 
Start by sterilizing your jars and lids in boiling water.
 
While the jars are heating, keep your pumpkin puree hot in a saucepan over low heat.
 
Fill each hot jar with pumpkin puree, leaving about 1 inch of headspace at the top.
 
Use a plastic spatula or bubble remover to remove air bubbles from the puree.
 
Wipe the rims of the jars with a clean, damp cloth to ensure a good seal.
 
Place the lids and rings on the jars, tightening them finger-tight.
 
Load the jars into your pressure canner according to the manufacturer’s instructions.
 
For pint jars, process at 10 pounds of pressure for 65 minutes, and for quart jars, process for 90 minutes.
 
Adjust pressure based on your altitude if you live above 1,000 feet.
 
Once the processing time is up, let the pressure canner cool down naturally before opening it.
 
Remove the jars and let them cool undisturbed for 12 to 24 hours.
 
Check that each lid has sealed by pressing down on the center, it should be firm and not pop up and down.
 

Tips for Storing and Using Home-Canned Pumpkin Puree

Store your sealed jars of pumpkin puree in a cool, dark place like a pantry or cellar.
 
Properly canned pumpkin puree will keep for up to a year, sometimes longer.
 
Once you open a jar, use it within a week and keep it in the fridge.
 
You can use your home-canned pumpkin puree in pies, muffins, pancakes, soups, curries, and even smoothies.
 
It’s also great for making pumpkin butter or adding moisture to baked goods.
 
If you notice any off smells, discoloration, or bubbling when you open a jar, toss it out, never risk it.
