Wash it, cut it in half, and scoop out the seeds.
Roast the halves face down on a baking sheet at 400°F for about 45 minutes until fork-tender.
Once cooled, scoop out the flesh and blend it until smooth.
2. Prepare Your Jars and Canner
Sterilize your jars and lids in boiling water.
Fill your pressure canner with the recommended amount of water and start heating it.
3. Fill the Jars with Puree
Spoon the puree into hot jars, leaving about 1 inch of headspace.
Remove air bubbles with a plastic spatula and wipe the rims clean.
Seal with lids and rings, but don’t overtighten.
4. Process in a Pressure Canner
Place jars in the pressure canner and process at 11 PSI for 55 minutes for pint jars or 90 minutes for quarts, adjusting for altitude.
Never use a water bath canner to can fresh pumpkin puree because it won’t reach the temperature needed to kill harmful bacteria.
5. Cool and Store
After processing, let the canner depressurize naturally.
Remove jars and let them cool for 12-24 hours.
Check seals, label, and store in a cool, dark place.

Check your local extension office for exact guidelines.
