Why You’ll Love This Eight-Layer Casserole:

Hearty and Filling: This dish combines pasta, beef, cheese, and vegetables for a complete, satisfying meal that’s ideal for family dinners.
Layered with Flavor: With eight delicious layers, each ingredient adds a unique texture and taste, from the meaty tomato sauce to the creamy cottage cheese and the crispy bacon.
Perfect for Make-Ahead Meals: This casserole is great for prepping in advance and reheats well, making it a convenient option for busy weeknights.
Customizable: Swap ingredients, add veggies, or use different cheeses to tailor this dish to your liking.

Key Ingredients:

Ground Beef: For the best flavor, use lean ground beef to avoid excessive grease. If you prefer, you can substitute ground turkey or chicken for a lighter option.
Tomato Sauce and Paste: The combination of tomato sauce, diced tomatoes, and tomato paste gives the casserole a rich, hearty tomato flavor. You could use Italian-seasoned diced tomatoes for added flavor.
Rotini Pasta: Rotini’s spiral shape holds onto the sauce and cheese well, but you can use other short pasta like penne or fusilli if you prefer.
Cottage Cheese: Cottage cheese adds a creamy layer with a slightly tangy flavor. Ricotta can be used as a substitute if you prefer a smoother texture.
Mozzarella Cheese: Shredded mozzarella melts beautifully, creating a gooey, cheesy layer. Feel free to mix in some shredded cheddar for added flavor.
Spinach: Using frozen, chopped spinach is convenient; just make sure to thaw and squeeze out excess water to prevent a watery casserole.
Bacon: Crumbled bacon adds a delicious smoky, savory crunch. Turkey bacon or a sprinkle of smoky paprika can be used as a substitute.
