This hearty spaghetti casserole bakes with meat sauce and a creamy layer of ricotta cheese. If you're a fan of crispy edges, you can bake it in a 9 1/2- or 10-inch-wide Bundt pan instead of the casserole dish, and the whole thing will have those wonderful edges! (Allow the same amount of time for baking, about 40 minutes covered and 15 minutes uncovered.) The recipe is a Yummly original created by Sara Mellas.
