Recipe: Boil spaghetti according to package instructions, drain and put them in a greased baking dish. Pour the meat sauce over the spaghetti and mix. Cover with the cheese and dot with butter. Cover the baking dish with tin foil and bake at medium temperature for about 30 minutes. Remove the tin foil and bake for 5 minutes more. Let the spaghetti casserole sit at room temperature for 10 minutes after it is done, and serve. Any left-over spaghetti casserole can be refrigerated and re-heated later to 165 F before serving again.
