Summer Squash - How to Preserve the Harvest
Here are some ways to preserve extra summer squash.
Nashville, Ark. – Do you have extra summer squash? If you’re like most home gardeners, you probably do. These vegetables grow abundantly, and it’s easy to find yourself with more than you know what to do with. If you’re eating a lot of it fresh, you may even get tired of it before long. The good news is there are several ways to preserve it.
Some people like to can their summer squash; however, that is no longer recommended. Squash is a low-acid vegetable which requires pressure canning for a unknown period to destroy the bacteria that causes botulism. While there used to be USDA-provided instructions for pressure-canning summer squash, they have been withdrawn. The reason is when they retested the old directions during a complete revision of the USDA guides, the results were not coming up consistently safe.
Basically, the problem is slices or cubes of cooked summer squash get too soft and pack tightly into the jars. The amount of squash filled into a jar then may affect the heating pattern and result in inadequate processing and an unsafe product.
So, what can you do to preserve your harvest? Try freezing or pickling.
Freezing or “putting up” vegetables as we often say here in the South is one of the easiest, most convenient, and least time-consuming ways to preserve foods.
Here are instructions for freezing summer squash:
- Wash, trim, and cut into ¼ inch slices.
- Blanch by boiling or steaming for about 3 to 5 minutes. This destroys the enzymes and bacteria that would over time, remove nutrients and flavor from the squash.
- Cool in ice water for at least 3 minutes. Moving quickly from heat to cold ensures the squash won’t be overcooked.
- Drain. This will remove excess moisture and prepare the squash for freezing.
- Spread the slices in single layer on cookie sheet and freeze just until firm.
- Package into freezer bags or freezer containers, leaving ½-inch headspace. Then seal, label and freeze.
To freeze squash for frying, just follow the instructions above, but before packaging, dredge in seasoned flour or cornmeal, spread in single layer on cookie sheet, and freeze until firm.
If you’re interested in pickling, try this recipe that has been tested and approved for safety. This is a favorite with my family.

If you have an abundance of squash in the garden, try an approved food preservation method. Just remember, food safety is always evolving so it’s important to use recipes that have been scientifically tested and are up to date. There’s a ton of information on canning out there, but if you want to do it safely, the sites you should refer to are So Easy to Preserve and the National Center for Home Food Preservation.
