Wash your summer squash, then trim off the ends.
 
Cut the squash into cubes or slices, depending on how you plan to use it later.
 
If you’re canning summer squash in jars for soups, cubes work great.
 
For casseroles, slices are easier to work with.

This step matters when you can summer squash in jars because temperature shocks can crack jars.
 

4. Pack the Jars

Fill each hot jar with squash, leaving about an inch of headspace.
 
Then pour boiling water over the squash, still keeping that inch of headspace.
 
When you can summer squash in jars, you can add a little salt for flavor if you like.
 

5. Remove Air Bubbles

Slide a bubble remover or plastic spatula down the sides of the jar.
 
This releases trapped air so the squash settles properly.
 
Then wipe the rims clean and place the lids on top.
 

6. Process in a Pressure Canner

Load your jars into the pressure canner and process pints for 30 minutes and quarts for 40 minutes at 10 pounds of pressure.
 
Always adjust for your altitude if you live above 1,000 feet.
 
This step is what makes it safe to can summer squash in jars.
