Ingredients

Scale

For the Pasta:

  • 16 oz spaghetti noodles

  • 3 tablespoons butter, sliced

For the Meat Sauce:

  • ½ lb ground beef

  • ½ lb Italian sausage

  • 1 small onion, chopped

  • 2 cloves garlic, minced

  • 24 oz marinara sauce (reserve ½ cup for layering)

  • Salt and pepper, to taste

For the Cheese Layer:

  • 8 oz cream cheese, softened

  • ¼ cup sour cream

  • 1 cup cottage cheese (or ricotta)

Toppings:

  • 2 cups shredded mozzarella cheese

  • ⅔ cup grated Parmesan cheese

Instructions

  1. Cook the Pasta:
    Boil spaghetti in salted water until al dente. Drain and set aside.

  2. Make the Meat Sauce:
    In a large skillet, cook ground beef and sausage until browned. Drain excess grease.
    Add chopped onion and garlic, cook until softened. Stir in marinara (reserve ½ cup for later). Simmer for 5–10 minutes.

  3. Make the Cheese Layer:
    In a medium bowl, mix cream cheese, sour cream, and cottage cheese until smooth.

  4. Assemble the Casserole:

    • Preheat oven to 350°F (175°C).

    • Place half the butter slices in a greased 9×13” baking dish.

    • Add half the spaghetti noodles.

    • Spread the cheese mixture evenly over noodles.

    • Layer remaining noodles on top, followed by remaining butter slices.

    • Pour meat sauce over everything and spread evenly.

    • Drizzle reserved marinara sauce over the top if desired.

    • Sprinkle mozzarella and Parmesan cheeses on top.

  5. Bake:
    Bake uncovered for 30–40 minutes, until hot and bubbly. If cheese starts browning too quickly, loosely cover with foil.

  6. Cool & Serve:
    Let sit for 10–15 minutes before serving for cleaner slices.

Notes

  • Want extra creaminess? Add more sour cream or a bit of heavy cream to the cheese mixture.

  • Swap cottage cheese with ricotta for a smoother texture.

  • Great make-ahead meal! Assemble, cover, and refrigerate up to 24 hours before baking.
