What is Spaghetti Squash?

Spaghetti squash is a healthy, hearty winter vegetable that grows in the ground. The vegetable is tough and it needs to be softened by baking before eating. Once it bakes, the hearty inside strands easily come apart by scraping a fork back and forth.

How do I find spaghetti squash at the grocery store? Spaghetti squash is creamy white to pale yellow in color. If your grocery store carries this vegetable, they will label it as spaghetti squash. It is not butternut squash, so be sure to check the labels to know what you are buying. Finally, choose a dry, firm squash. It should not have any soft spots. PRO TIP: Weigh the spaghetti squash at the store in order to scale it easier to recipes you find online.

Does spaghetti squash taste like pasta? No, it does not taste the same. It is mostly tasteless, however, it does have a slightly sweet taste. If you add herbs, seasoning, and sauces to the baked spaghetti squash, it balances the taste. Cooked spaghetti squash reminds me the most of thin glass noodles. That’s because once the winter squash is baked, small fibrous strands unravel that look nearly identical to glass noodles.
