Step 3: Assemble the Casserole
- Preheat your oven to 350°F (175°C).
- Grease a 9×13-inch baking dish with cooking spray.
- Place half of the cooked spaghetti in an even layer at the bottom of the dish. Spread half of the butter slices over the spaghetti.
- Spread the creamy cheese mixture over the layer of pasta.
- Add the remaining spaghetti on top of the cheese layer and dot with the remaining butter slices.
- Pour the meat sauce evenly over the top of the pasta layers.
Step 4: Add Cheese Topping and Bake
- Sprinkle shredded mozzarella and Parmesan cheese evenly over the meat sauce.
- Cover the baking dish with aluminum foil and bake for 30 minutes.
- Remove the foil and bake for an additional 10–15 minutes, or until the cheese on top is melted and bubbly, and the casserole is heated through.
Step 5: Serve and Enjoy
- Allow the casserole to cool for about 5–10 minutes before serving. This will help it set and make it easier to slice into portions.
- Serve with a fresh green salad, garlic bread, or steamed vegetables on the side.
Tips for Making the Best Million Dollar Spaghetti Casserole
- Use a Combination of Meats: Using a mix of ground beef and Italian sausage can add more depth to the flavor of the meat sauce.
- Choose Your Cheese Wisely: Cottage cheese provides a lighter texture, while ricotta cheese gives a creamier, slightly richer taste. Use whichever you prefer, or a mix of both!
- Cook Spaghetti to Al Dente: Cooking the spaghetti just until it’s al dente ensures it won’t become mushy during baking.
- Make It Ahead: This casserole can be made ahead of time, which is perfect for meal prep. Assemble it, cover with foil, and store in the refrigerator for up to 2 days. Bake as directed when ready.
- Freeze for Later: Million Dollar Spaghetti Casserole freezes well. Assemble it in a freezer-safe dish, cover tightly with plastic wrap and aluminum foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking.
- Customize with Extra Veggies: Add sautéed bell peppers, mushrooms, or spinach to the meat sauce for extra nutrition and flavor.
