Creamy, cheesy jumbo pasta shells filled with a ricotta and sun-dried tomato mixture, baked in marinara sauce and topped with melted mozzarella and Parmesan cheese. A comforting Italian-American main dish perfect for weeknights or entertaining.
Use whole-milk ricotta cheese for the creamiest filling., Do not overcook pasta shells; al dente works best to prevent mushiness when stuffing., This dish can be assembled ahead of time and refrigerated for up to 24 hours before baking., Unbaked stuffed shells freeze well for up to 3 months; thaw overnight in fridge before baking., Reheat leftovers in the oven at 350°F (175°C) for 15-20 minutes until heated through and bubbly., Mix-ins such as cooked Italian sausage, ground beef, shredded chicken, or sautéed spinach can be added for variation., For a dairy-free option, use cashew ricotta or store-bought dairy-free cheeses.
