Step 3: Make the Creamy Layer

  1. In a medium bowl, combine cream cheese, sour cream, mayonnaise, garlic powder, and onion powder.
  2. Mix until smooth and creamy. This layer will add the “million-dollar” richness that sets this casserole apart.

Step 4: Assemble the Casserole

  1. Preheat your oven to 350°F (175°C).
  2. Grease a 9×13-inch baking dish lightly with butter or cooking spray.
  3. Spread a thin layer of meat sauce at the bottom of the dish.
  4. Layer half of the cooked spaghetti over the sauce.
  5. Dollop half of the creamy mixture over the spaghetti and gently spread it with a spatula.
  6. Pour half of the remaining meat sauce on top.
  7. Sprinkle 1 cup of mozzarella and some Parmesan cheese over the layer.
  8. Repeat layers with the remaining spaghetti, creamy mixture, meat sauce, and finish with the remaining mozzarella, Parmesan, and optional cheddar.

Step 5: Bake to Perfection

  1. Cover the casserole with aluminum foil and bake for 20 minutes.
  2. Remove the foil and bake for an additional 10–15 minutes until the top is golden, bubbly, and slightly crispy.
  3. Let it rest for 5 minutes before serving to allow the layers to set.

Step 6: Serve and Enjoy

  • Garnish with fresh parsley or basil for a pop of color and flavor.
  • Serve hot and watch it disappear! This casserole pairs beautifully with a crisp green salad or garlic bread.

Tips for the Perfect Million Dollar Spaghetti Casserole

  • Cheese variations: Feel free to experiment with provolone, Monterey Jack, or even a little blue cheese for a twist.
  • Add vegetables: Bell peppers, mushrooms, or spinach can be added to the meat sauce for extra nutrition.
  • Make ahead: Assemble the casserole a day ahead and refrigerate; bake it the next day for an even richer flavor.
  • Spicy kick: Add red pepper flakes or a splash of hot sauce to the meat sauce for heat.
