How To Preserve Squash And Zucchini

You can preserve squash and zucchini by freezing, canning, dehydrating, or simply storing them properly for short-term use.
 
Whether you’ve got a bumper crop from your garden or grabbed too many at the farmers market, learning how to preserve squash and zucchini is the key to enjoying them all year long.
 
The good news is that preserving squash and zucchini is easier than you might think.
 
In this post, we’ll walk through the best ways to preserve squash and zucchini so nothing goes to waste.
 

Why You Should Preserve Squash and Zucchini

Squash and zucchini are notorious for producing more than you can eat in a single season.
 
If you’ve ever grown zucchini, you know exactly what I mean.
 
One day they’re tiny, and the next day they’re the size of a baseball bat.
 
Preserving squash and zucchini lets you capture that summer freshness and enjoy it in soups, casseroles, and baked goods during the colder months.
 
It also saves you money because you’re not buying out-of-season produce at premium prices.
 
Plus, home-preserved squash and zucchini taste way better than anything from a can at the grocery store.
 

1. Freezing Squash and Zucchini

Freezing is one of the easiest ways to preserve squash and zucchini.
 
Start by washing your squash and zucchini thoroughly and cutting off the ends.
 
If you’re freezing zucchini, you can slice, dice, or shred it depending on how you plan to use it later.
 
Shredded zucchini is perfect for baking bread and muffins.
 
Sliced zucchini works great in stir-fries and casseroles.
 
For squash, peel it, remove the seeds, and cut it into cubes or slices.
 
The key step when you freeze squash and zucchini is blanching.
 
Blanching stops enzyme activity that causes texture and flavor loss during freezing.
 
Drop your squash or zucchini pieces into boiling water for about three minutes.
 
Then transfer them immediately to an ice bath to stop the cooking process.
 
Drain them well and pat them dry.
 
Spread the pieces on a baking sheet and freeze them individually before transferring to freezer bags.
 
This method keeps your preserved squash and zucchini from clumping together.
 
They’ll stay good in the freezer for up to ten months.
 

2. Canning Squash and Zucchini

Canning is another popular way to preserve squash and zucchini, but there’s an important caveat.
 
You should never water-bath can squash or zucchini because they’re low-acid foods.
 
That means they need a pressure canner to be safely preserved.
 
The USDA recommends pressure canning squash and zucchini in cubes or slices.
 
Pack the pieces into hot jars, leaving about an inch of headspace.
 
Add boiling water or broth to cover the pieces, then process the jars according to your pressure canner’s instructions.
 
This usually takes around 30 to 40 minutes at the proper pressure.
 
When you preserve squash and zucchini this way, they’ll last on your shelf for up to a year.
 
You can also make zucchini relish or pickled zucchini using a water-bath canner because the added acid makes them safe.
 

3. Dehydrating Squash and Zucchini

Dehydrating is a fantastic option if you’re short on freezer space.
 
To preserve squash and zucchini by drying, start by washing and slicing them thinly and evenly.
 
A mandoline slicer makes this job much faster.
 
You can leave the skin on zucchini for extra nutrients and color.
 
For squash, peel it first if the skin is tough.
 
Spread the slices in a single layer on your dehydrator trays.
 
Set the temperature to around 125°F and let them dry for six to ten hours.
 
They’re done when they’re brittle and snap easily.
 
Store your dried squash and zucchini in airtight containers or vacuum-sealed bags.
 
They’ll keep for at least a year in a cool, dark place.
 
Rehydrate them in warm water or toss them straight into soups and stews.
 

4. Pickling and Fermenting

Pickling is a delicious way to preserve squash and zucchini.
 
You can make refrigerator pickles or shelf-stable pickles using a water-bath canner.
 
The vinegar and salt in pickling brine create an environment where harmful bacteria can’t survive.
 
Slice your zucchini into spears or rounds and pack them into jars.
 
Add garlic, dill, and peppercorns for flavor.
 
Pour hot brine over the top and seal the jars.
 
Fermenting is another traditional method to preserve squash and zucchini.
 
Lacto-fermentation uses salt to encourage beneficial bacteria that preserve the vegetables naturally.
 
Fermented zucchini has a tangy, slightly sour flavor that’s great for gut health.
 

5. Short-Term Storage Tips

If you’re planning to use your squash and zucchini within a week or two, simple storage works fine.
 
Don’t wash them until you’re ready to use them.
 
Moisture speeds up spoilage.
 
Store zucchini in a perforated plastic bag in the crisper drawer of your fridge.
 
Squash likes slightly cooler temperatures and good airflow.
 
Keep winter squash in a cool, dark spot like a pantry or basement.
 
Check on them regularly and remove any that show signs of soft spots or mold.
 
This way you preserve squash and zucchini for weeks without any special equipment.
 

So, How Do You Preserve Squash and Zucchini?

You can preserve squash and zucchini by freezing, pressure canning, dehydrating, pickling, or fermenting them.
