Can you eat the outside of a spaghetti squash?

Yes, you can eat the outside of a spaghetti squash, but it is typically tough and not very palatable. Most people prefer to cook the squash and eat the flesh inside, which has a stringy texture resembling spaghetti. If you choose to eat the skin, make sure to wash it thoroughly to remove any dirt or pesticides. However, it's generally recommended to focus on the inner flesh for the best flavor and texture.
