Can You Freeze Spaghetti Squash?

You can freeze spaghetti squash to save leftovers or make meal prep even simpler.

Spaghetti squash is one of our favorite types of winter squash. It has the most unique texture! Instead of becoming soft and mushy like other winter squash, cooked spaghetti squash shreds and turns into skinny squash noodles. It tastes delicious in casseroles and stir-fry dishes, and it’s an excellent low-carb, high-fiber substitute for pasta.

If you’re like me, you probably load up on spaghetti squash when it’s in season at the farmers market or on sale at the store. It’s easy to buy too many, but we have good news: Not only can you freeze spaghetti squash, it’s also an easy way to prep spaghetti squash recipes.

Can You Freeze Cooked Spaghetti Squash?

Yes—and it freezes exceptionally well.

It’s easy to cook spaghetti squash—about 40 to 60 minutes in a 350°F oven, depending on the vegetable’s size—but that’s too long for a quick weeknight dinner. Even Instant Pot spaghetti squash takes a while; the squash cooks in seven minutes, but that doesn’t account for all the time to build and release pressure. Having frozen spaghetti squash on hand speeds things up!

Every pound of spaghetti squash makes about 1-1/4 cups of spaghetti squash strands, so a four-pound squash should make about five cups of cooked squash. Freeze the cooked squash in 2-1/2 cup bags to make portion sizing easy upon reheating.

How to Freeze Spaghetti Squash

There are two factors to remember to keep the right texture. For starters, spaghetti squash must be cooked first to prevent the cell walls from breaking down in the freezer, leading to a pile of mush when it’s thawed. The second secret is to drain the cooked squash before popping it in the freezer. This removes excess moisture and ensures the texture will be perfect.

After cooking, run a fork through the squash to release the strands. Place the squash in a colander and set it over a bowl in the refrigerator. Let the squash sit overnight before packing the strands into freezer-safe bags. Frozen spaghetti squash will retain its best quality in the freezer for about six months.

How to Thaw Frozen Spaghetti Squash

For most recipes, you don’t even need to thaw the spaghetti squash! Since it’s been previously cooked, you can add it to a simmering sauce (like this delicious meat sauce) and let the heat of the sauce do the work for you. You can also take it out of the freezer the night before you plan to use it, and the squash will thaw in about 12 hours in the refrigerator.
