How to Can Patty Pan Squash Step by Step
Learning how to can patty pan squash takes a few simple steps.
Follow this method, and you’ll have jars ready in about two hours.
1. Pick and Prep the Squash
Start with fresh, firm patty pan squash that are small to medium in size.
Wash them well, then cut off the stem and blossom ends.
You can leave the skin on or peel it, but leaving it on holds more nutrients.
Cut the squash into 1-inch cubes or slices, depending on how you plan to use them later.
2. Blanch the Squash
Blanching is a step many people skip, but it helps you can patty pan squash with better texture and color.
Drop the cubes into boiling water for 3 minutes, then transfer them straight into ice water.
This stops the cooking and keeps the squash from turning mushy.
Drain the cooled squash well before packing.
3. Pack the Jars
Fill clean, hot pint or quart jars with the blanched patty pan squash.
Leave 1 inch of headspace at the top.
Add ½ teaspoon of canning salt per pint or 1 teaspoon per quart if you like, but salt is optional.
Then pour boiling water over the squash, still keeping that 1-inch headspace.
Run a plastic knife around the inside to remove air bubbles.
4. Pressure Can the Jars
This is the most important part of how to can patty pan squash safely.
Wipe the jar rims, place the lids and rings on, and load the jars into your pressure canner.
Process pints for 30 minutes and quarts for 40 minutes at 10 pounds of pressure, adjusting for your altitude.
Let the canner cool naturally, then remove the jars and check the seals.
5. Store and Label
Once the jars cool, press the center of each lid.
If it doesn’t pop, the jar is sealed and you’ve successfully canned patty pan squash.
Label with the date and store in a cool, dark place for up to 12 months.
Common Mistakes When You Can Patty Pan Squash
Even easy projects go wrong, so avoid these pitfalls when you can patty pan squash:
1. Using a Water Bath Instead of a Pressure Canner
Never can patty pan squash in a boiling water bath.
Low-acid vegetables need the higher temperature of a pressure canner to be safe.
2. Overpacking the Jars
Crowding the squash too tightly prevents proper heat penetration.
Leave that full inch of headspace so liquid can circulate.
3. Skipping the Blanching Step
If you skip blanching, you can patty pan squash that turns dark and mushy.
Blanching sets the color and firms the flesh.
4. Ignoring Altitude Adjustments
Pressure changes with elevation, so check your local guidelines.
Above 1,000 feet, you’ll need more pounds of pressure to can patty pan squash safely.
