What to Serve with Baked Spaghetti Casserole

I love to serve this baked spaghetti casserole with a simple crunchy green salad like my house salad recipe with a basic vinaigrette dressing or a creamy ranch dressing and a crusty loaf garlic bread. Perfection!

Recipe Tips and Variations

Cheese Swap: Try cottage cheese in place of the ricotta for added protein or use provolone in place of the mozzarella for a smokier flavor.

Meat Options: Substitute ground beef with ground chicken or ground turkey, Italian sausage, or use a mix of ground pork and ground beef for extra depth of flavor.

Veggie Boost: Stir in one cup of sauteed spinach, bell peppers, along with the onions in the meat sauce.

Time Saving Tip: Use your favorite high-quality store-bought marinara to save time or if you prefer homemade, make a large batch in advance and freeze to use in recipes such as these!

Kid-Friendly Tip: Break the spaghetti into smaller pieces before cooking for easier scooping and eating, especially for little ones.

Vegetarian: Use sauteed mushrooms, zucchini, or lentils in place of meat.

Gluten-Free: Use your favorite gluten-free spaghetti and certified gluten-free ingredients to make this dish gluten-free friendly.

Storage and Make-Ahead Instructions

Refrigerator: Store leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave (1-2 minutes, stirring halfway through cooking until warmed throughout). OR Cover with foil and warm in the oven at 350ºF for 15 – 20 minutes until heated through.

Freezer: This casserole freezes beautifully. Assemble the dish up to the baking step, wrap tightly in plastic wrap and then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed. If baking from frozen, cover with foil and add 15-20 minutes to the initial baking time, then uncover top with final cheese topping and bake until bubbly.

Reheating Tip: To keep leftovers moist, add a splash of water or marinara sauce before reheating, and cover to trap the steam.
