Million Dollar Spaghetti Casserole


  1. Preheat your oven to 375°F (190°C).
  2. Lightly grease a 9x13-inch baking dish or similar-sized casserole dish.

2. Cook the Spaghetti

  1. Bring a large pot of salted water to a boil. Cook the spaghetti according to package instructions until al dente.
  2. Drain the spaghetti and set aside.

3. Prepare the Meat Sauce

  1. In a skillet over medium heat, cook the ground beef until browned and crumbled, about 6–8 minutes.
  2. Add the diced onion and minced garlic to the skillet and cook for an additional 3–4 minutes, until softened.
  3. Stir in the marinara sauce, Italian seasoning, salt, and black pepper. Simmer for 5 minutes to allow the flavors to meld. Remove from heat.

4. Make the Creamy Layer

  1. In a mixing bowl, combine the softened cream cheese, sour cream, Parmesan cheese, and 1 cup of shredded mozzarella cheese.
  2. Stir until smooth and well combined.

5. Assemble the Casserole

  1. Spread half of the cooked spaghetti evenly on the bottom of the prepared baking dish.
  2. Spoon half of the creamy cheese mixture over the spaghetti and spread it out evenly.
  3. Top with half of the meat sauce, spreading it to cover the creamy layer.
  4. Repeat the layers: remaining spaghetti, creamy cheese mixture, and meat sauce.
  5. Sprinkle the remaining 1 cup of shredded mozzarella cheese evenly over the top.

6. Bake

  1. Cover the casserole with aluminum foil and bake in the preheated oven for 20 minutes.
  2. Remove the foil and bake uncovered for an additional 10–15 minutes, or until the cheese is melted, bubbly, and slightly golden.
  3. Optional: Broil for 2–3 minutes at the end for extra browning (watch closely to avoid burning).

7. Serve and Enjoy

  1. Remove the casserole from the oven and let it cool slightly before serving.
  2. Garnish with fresh parsley or red pepper flakes for added brightness.
  3. Enjoy every bite of this rich, cheesy, and comforting spaghetti casserole!
  4. Perfect as a standalone meal or paired with a side salad or garlic bread for a complete feast.

Tips for Success

  • Use Fresh Ingredients: Fresh garlic, herbs, and high-quality cheese make a noticeable difference in flavor.
  • Switch Proteins: Substitute ground beef with turkey, chicken, pork, or plant-based alternatives for variety.
  • Add Veggies: Stir in spinach, mushrooms, or zucchini for added nutrition.
  • Store Leftovers: Store in an airtight container in the fridge for up to 3 days. Reheat gently in the oven or microwave before serving.
