To properly store squash, you need to create the right environment based on the type you’re dealing with.
Winter varieties like butternut, acorn, and spaghetti squash store beautifully for months when kept in a cool, dark, and dry spot.
Summer squash like zucchini and yellow crookneck, on the other hand, need a completely different approach since they’re harvested while still tender.
If you’ve ever wondered how to properly store squash so it stays fresh instead of turning mushy or moldy, you’re in the right place.
The way you store squash depends heavily on whether you’re working with a thick-skinned winter type or a thin-skinned summer variety.
Get the conditions right, and you’ll be enjoying your harvest for weeks or even months.
Get them wrong, and you’ll be tossing sad, wrinkled squash into the compost before you know it.
In this post, we’ll walk through exactly how to properly store squash, covering everything from curing to temperature to common mistakes.
Let’s dive in.
How to Properly Store Squash: The Basics
Learning how to properly store squash starts with understanding that not all squash are created equal.
Treating a butternut the same way you’d treat a zucchini is a recipe for disappointment.
The good news is that once you know a few simple rules, storing squash becomes second nature.
Here’s what matters most.
1. Cure Winter Squash Before Storing
Curing is the secret step many people skip, and it makes a huge difference.
To properly store squash that’s a winter variety, you first need to cure it for about 7 to 14 days.
Curing means keeping the squash in a warm, well-ventilated spot around 80 to 85°F with decent humidity.
This process hardens the skin and heals any small nicks or scratches.
A tougher skin means the squash can sit in storage for months without rotting.
Skip curing, and your squash may only last a few weeks before it starts to soften.
2. Keep the Temperature Cool and Consistent
Once cured, winter squash likes a cool, steady temperature between 50 and 55°F.
That’s cooler than your average room but warmer than a fridge.
A root cellar, a cool basement, or an unheated pantry works beautifully.
Avoid spots where temperatures swing wildly, like a garage that freezes at night and warms up during the day.
Big temperature changes cause condensation, and moisture is the enemy of stored squash.
3. Choose a Dark, Dry Space
Light and dampness both shorten the shelf life of squash.
Store your squash somewhere dark, dry, and away from direct sunlight.
Humidity should stay around 50 to 60 percent.
Too much moisture invites mold, while too little causes the squash to shrivel.
A dark closet or a shelf in a cool pantry is often all you need to properly store squash.
4. Give Them Space to Breathe
Never pile squash on top of each other or stack them in a tight bin.
Air needs to circulate around each one to prevent rot from spreading.
Set them in a single layer on a shelf, leaving a little gap between each squash.
If you’re short on space, you can hang them in mesh bags or use a slatted crate.
And check on them every couple of weeks, removing any that show soft spots right away.
One bad squash can spoil the whole batch.
How to Properly Store Summer Squash
Summer squash is a different story, and storing it takes a bit more care.
These thin-skinned varieties don’t cure well and won’t last for months.
Your best bet is the refrigerator.
Here’s how to properly store squash like zucchini and yellow squash.
1. Don’t Wash Until You’re Ready to Use It
Washing summer squash adds surface moisture, which speeds up spoilage.
Instead, gently wipe off any dirt with a dry cloth or paper towel.
Wash it right before cooking, not before storing.
2. Store in the Crisper Drawer
Place your summer squash in a perforated plastic bag or a container lined with a paper towel.
Put it in the crisper drawer, which has the right humidity level.
The paper towel absorbs extra moisture, and the bag keeps the squash from drying out.
Stored this way, summer squash stays fresh for about one to two weeks.
3. Freeze It for Longer Storage
If you have more summer squash than you can eat, freezing is a great option.
Slice or cube it, blanch for a few minutes, then plunge it into ice water.
Drain well, pat dry, and freeze in airtight bags.
Frozen summer squash keeps for up to a year, though it’s best used in cooked dishes.
So, How Do You Properly Store Squash?
To properly store squash, you simply match the method to the type you’re working with.
Winter squash needs curing, a cool dark spot, and room to breathe so it can last for months.
Summer squash belongs in the fridge, unwashed and tucked into the crisper.
And when you’re overwhelmed with a bumper crop, freezing is always a reliable backup.
Follow these tips, and you’ll be able to properly store squash all season long without losing a single one.
