Spaghetti squash is almost magical: you start with a firm oval squash, in appearance not unlike those sitting next to it in the supermarket. But once roasted, spaghetti squash couldn’t be more different than its fellow squash! The flesh breaks into long firm threads that have a striking resemblance to the pasta it’s named for.

What to Know About Cooking Spaghetti Squash

Spaghetti squash tastes like the slightly sweet nuttiness of summer squash with a hint of the winter squash flavor you’d expect from a pumpkin. The long treads almost pop when you bite into them and maintain an al dente quality when roasted.

Spaghetti squash easily takes on the flavors of the recipe you are using it in, which means that sauces, seasonings, and dressings all work well. It can be served like pasta with marinara or pesto, but it’s also delicious baked into breakfast casseroles or served like a pasta salad with olives and crumbled feta.

Roasting is the Best Way to Cook Spaghetti Squash

There are quite a few ideas out there on how to cook spaghetti squash, but the truth is, it shines best when you roast it. Roasting the squash slightly caramelizes the edges and deepens the flavor.

Roasting also helps dry out the squash so that it easily pulls away from the skin, which is a good thing since spaghetti squash holds a lot of water and you don't want to transfer that liquid to your recipe.

Another important step? Salting spaghetti squash before you roast it! This also works to draw out moisture and keep the squash from being too watery later on.

Of course, each squash is a little different. A vegetable’s water content varies from season to season due to growing conditions. If you find your squash is still too watery even after salting and roasting, let it sit in a strainer to drain excess liquid after it's cooked, kind of like how you’d drain pasta noodles in a colander. You can also squeeze it if you wish, but this tends to crush the threads and take away some of its appealing texture, so do so gently.

  6. Roast until tender, then cool:

    Place the squash in the oven and roast for 30 to 40 minutes. The squash is done when you can pierce through the skin and the flesh is tender. Flip the squash to be cut-side up and allow it to cool until you can handle it, about 10 minutes.
