Cheesy Spaghetti Squash Casserole

Cheesy Spaghetti Squash Casserole is an Italian dish not because of the "spaghetti," but because of the flavors. There's no spaghetti in this dish at all. Spaghetti squash is what takes center stage. This easy squash casserole is great for fall. Mozzarella, Parmesan, marinara sauce, mushrooms, peppers, onion, and garlic make this a healthy, vegetarian Italian dish. This lightened-up casserole isn't as heavy as traditional pasta dishes, so you won't feel weighed down. This recipe has all the flavor of a baked pasta casserole but is loaded with good-for-you vegetables.
