If you’ve been wondering how to preserve summer squash so your garden haul doesn’t go to waste, you’re in the right place.
Summer squash is versatile, and there are several ways you can preserve summer squash to enjoy it long after the season ends.
In this post, we’ll walk through the best methods to preserve summer squash, plus tips to keep it tasting fresh.
Let’s dive in.
Why You Should Preserve Summer Squash
You should preserve summer squash because it spoils quickly and you don’t want all that hard work in the garden to go to waste.
Summer squash has a high water content, which means it can go bad within a week or two if you just leave it on the counter.
By learning how to preserve summer squash, you can stretch your harvest across months instead of days.
Another reason to preserve summer squash is that it’s incredibly abundant.
If you’ve ever grown zucchini or yellow squash, you know one plant can produce more than you can eat fresh.
Preserving summer squash lets you enjoy your favorite recipes year-round.
Plus, you can preserve summer squash in ways that suit your cooking style.
Whether you love soups, casseroles, or baked goods, there’s a preservation method for you.
The key is to pick the method that works best for your kitchen and your time.
How to Freeze Summer Squash
Freezing is one of the easiest ways to preserve summer squash, and it works well for most recipes.
Here’s how to freeze summer squash properly so it doesn’t turn to mush.
1. Choose and Wash Your Summer Squash
Start by picking firm, young summer squash for the best results.
If you want to preserve summer squash that’s tender, avoid overgrown ones with big seeds.
Wash the summer squash under cool running water and pat it dry.
2. Slice or Cube the Squash
Slice or cube your summer squash into pieces that are about half an inch thick.
When you preserve summer squash this way, uniform pieces freeze and thaw evenly.
You can also shred summer squash if you plan to use it in breads or fritters.
3. Blanch for Best Results
Blanching helps preserve summer squash by stopping enzymes that cause mushiness.
Drop the squash pieces into boiling water for about three minutes, then transfer them to an ice bath.
Once you preserve summer squash with blanching, the texture holds up much better.
4. Freeze on a Tray Before Bagging
Spread the blanched and dried squash on a baking sheet and freeze it for a couple of hours.
This step keeps the pieces from clumping together when you preserve summer squash in bags.
Then transfer the frozen pieces into freezer bags and squeeze out the air.
Label the bags with the date, and your preserved summer squash will keep for up to a year.
Canning and Pickling Summer Squash
Canning and pickling are two more ways to preserve summer squash that add flavor and shelf stability.
These methods work best if you enjoy tangy, seasoned squash in salads or on sandwiches.
1. Pickling Summer Squash
Pickling is a fantastic way to preserve summer squash with a bold, briny taste.
You can preserve summer squash in a simple brine of vinegar, water, salt, and sugar.
Pack sliced summer squash into jars with garlic, dill, and peppercorns for extra flavor.
Refrigerator pickles are the easiest option if you want to preserve summer squash without a pressure canner.
2. Water Bath Canning
If you want to preserve summer squash on the shelf, water bath canning with added acid works well.
Summer squash is a low-acid food, so you must add lemon juice or vinegar to make it safe.
Follow a tested recipe when you preserve summer squash this way to avoid any risks.
Properly canned summer squash lasts about a year in a cool, dark pantry.
3. Pressure Canning for Safety
For plain canned summer squash without acid, a pressure canner is the only safe option.
When you preserve summer squash in a pressure canner, you eliminate harmful bacteria.
Always check your canner’s instructions and process at the correct pressure for your altitude.
This method takes more effort, but it’s a reliable way to preserve summer squash.
Dehydrating Summer Squash
Dehydrating is another smart way to preserve summer squash if you’re short on freezer space.
Dried summer squash is lightweight and perfect for soups, stews, and backpacking meals.
1. Slice Thinly and Evenly
To preserve summer squash by drying, slice it into thin, even rounds or chips.
Aim for about an eighth of an inch so everything dries at the same rate.
2. Dry at the Right Temperature
Spread the slices on your dehydrator trays and dry them at around 125°F.
It usually takes six to ten hours to preserve summer squash this way.
The pieces are ready when they’re leathery and brittle, with no moisture left.
3. Store in Airtight Containers
Once dried, let the slices cool and then store them in airtight jars.
When you preserve summer squash in this form, it keeps for up to a year in a dark cabinet.
You can rehydrate the slices in warm water before tossing them into your favorite dish.
So, How Do You Preserve Summer Squash?
You preserve summer squash by freezing, canning, pickling, or dehydrating it, depending on your needs.
If you want the simplest route, freezing is the way to preserve summer squash without much fuss.
For shelf-stable options, canning and pickling let you preserve summer squash for a year or more.
And if you’re tight on space, dehydrating is a great way to preserve summer squash too.
No matter which method you choose, you can preserve summer squash and enjoy your harvest all year.
