Start with a firm, mature Hubbard squash with no soft spots.

2. Cook the Squash

You can bake, steam, or pressure cook the squash until the flesh is tender.
 
Once it’s soft, scoop the flesh out and mash it or cut it into cubes.
 

3. Get Your Jars Ready

Wash your jars, lids, and rings in hot soapy water, then keep them hot until you’re ready to fill them.

Add boiling water to cover the squash, then remove air bubbles with a plastic spatula.
 

5. Pressure Can It

Process pint jars at 11 pounds of pressure for 55 minutes, and quart jars for 90 minutes, adjusting for your altitude.

Overripe Hubbard squash can be mushy and may not hold up well during canning.
 

3. Not Venting the Canner

Always let your pressure canner vent steam for 10 minutes before building pressure to ensure safety.
