No-Boil Pasta Casserole with Ricotta and Mozzarella

This convenient pasta casserole skips the boiling step by cooking uncooked pasta directly in marinara sauce and water in the oven. Layers of creamy ricotta and melted mozzarella create a satisfying comfort food perfect for busy weeknight dinners or feeding a crowd. The pasta absorbs the seasoned sauce as it bakes, resulting in tender noodles and rich flavors in one dish with minimal prep work.
