What is Summer Squash?

First off, let’s talk about squash and the differences between summer squash and winter squash.

Summer squash is planted in the spring and can be planted throughout the summer for a continuous harvest. The plants are more compact and take up less room than winter squash.

Summer squash varieties include yellow squash, crookneck, zucchini, bush marrow, patty pan, and zephyr squash. Summer squash has a higher water content and a shorter shelf life than winter squash, which means you need to preserve it if you want to enjoy it after the garden is finished for the season.

When talking about preserving squash in this article, I am talking about SUMMER squash, not winter squashes such as butternut, hubbard, or pumpkins. (but here’s how to preserve winter squash!)

Before jumping in to  how to preserve summer squash, let me just mention that summer squash tends to get rather mushy no matter how you preserve it.  So when you are using canned or frozen squash, chances are it will just fall apart in whatever meal you are using it in.

It’s still full of nutrition and taste, but you won’t be able to saute zucchini from frozen quite like you can fresh!


Freezing Summer Squash

My favorite way of preserving summer squash is to freeze it.  To me, freezing is the simplest method and it retains more of the taste that I want in my squash.

I also prefer to freeze my squash without blanching. Blanching supposedly stops the enzymes that can degrade your squash over time, but I haven’t really noticed a difference in taste and blanching makes the squash even more mushy when defrosted.

I simply slice, grate, or dice my squash and stick it in a freezer bag. Remove as much air as possible and put it in the freezer. Try to use it in about a year.

Here’s how I do frozen zucchini- for easy measured portions.

Pressure Canning Squash

If you want to can squash, you will need to use a pressure canner. It can’t be canned on their own using a water bath canner.

Pressure canning can seem a little scary if you aren’t used to it, but it’s really not that hard! You can pick up a copy of the Quick Start Guide to Pressure Canning if you need help getting started.

Usually you will either can sliced or diced summer squash. Here’s a couple tutorials to get you started:

Water Bath Canning Squash

If you don’t own a pressure canner, or you just aren’t comfortable pressure canning, there are someways to preserve summer squash using a water bath canner. While, it can’t be canned PLAIN in a water bath, if you add in some acids, you can safely can summer squash using this method.

This means either adding in something like vinegar- and pickling. Or adding in sugar.

For example, you can make my cucumber relish recipe and exchange zucchini or other summer squash in for the cucumbers.

Here are some other ways to preserve summer squash using a water bath canner:

Dehydrating Squash

Dehydrating is another great option for preserving your summer squash. I have an Excalibur 9 Tray Food Dehydrator that I LOVE and use all summer long, but you can also check out my Dehydrator Buying Guide for other options.

To dehydrate squash you can either slice it or dice it- you don’t have to peel it first.

Dehydrate at 125F until leathery and dry. This may take between 10-14 hours depending on thickness and humidity.

One of my favorite ways of dehydrating summer squash is sliced thin, seasoned, and dried into chips.  I use the same method as described in my Cucumber Chips article.

We also love to make dried Zucchini Pineapple Candy. It’s super easy and a  healthy, dessert-like treat!

You can even dry your squash and grind it into a powder to add to smoothies, soups, sauces, or baked goods. 

Here’s more on dehydrating zucchini.

Freeze Drying Squash

Now, not everyone has a freeze dryer, but it’s still a great option for preserving summer squash!

Freeze drying allows you to preserve squash that retains most of its nutritional value and lasts much longer than any other preservation method- up to 25 years in some cases.

You can even make freeze dried squash in slices, grated, or chunks and use it just as you would other preserved squash- in baked goods, soups, stews, smoothies, and more.

HarvestRight makes a line of Home Freeze Dryers that work quite well for preserving all kinds of foods. Here’s their guide on Freeze Drying Zucchini to check out more about it.



Fermenting Squash

I am not a huge fermented foods fan, but that doesn’t mean it’s not a super healthy way of preserving your fresh homegrown produce!

You can preserve zucchini and other summer squash by fermenting too! They will turn out similarly to the pickled squash we’ve already talked about.

Here are a couple fermented squash recipes to try out:
