Ingredients You’ll Need

16 ounces (450 g) spaghetti
1 pound (450 g) lean ground beef
1 small onion, finely diced
3 cloves garlic, minced
24 ounces (680 g) marinara or pasta sauce
8 ounces (225 g) cream cheese, softened
1 cup sour cream
1 cup cottage cheese or ricotta cheese
4 tablespoons unsalted butter, sliced
2 cups shredded mozzarella cheese
½ cup grated Parmesan cheese
1 teaspoon Italian seasoning
½ teaspoon garlic powder
Salt and freshly ground black pepper, to taste
Fresh parsley, chopped, for garnish

Ingredient Notes

Spaghetti: Cook until just al dente so it doesn’t become overcooked while baking.

Ground Beef: Lean ground beef provides rich flavor, but ground turkey or Italian sausage also work well.

Marinara Sauce: Choose a high-quality marinara sauce or use your favorite homemade version for the best flavor.

Cream Cheese: Softened cream cheese creates the signature rich and creamy layer that gives this casserole its “million dollar” texture.

Sour Cream: Adds a subtle tang and makes the cheese filling extra smooth.

Cottage Cheese or Ricotta: Either works beautifully. Cottage cheese creates a lighter texture, while ricotta is richer and creamier.

Mozzarella: Freshly shredded mozzarella melts beautifully into a bubbly, golden topping.

Parmesan: Adds a savory, nutty finish and enhances the overall flavor of the casserole.

How to Make Million Dollar Spaghetti Casserole

1. Prepare the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

2. Cook the Spaghetti
Bring a large pot of salted water to a boil and cook the spaghetti until just al dente. Drain well and set aside.

3. Make the Meat Sauce
Heat a large skillet over medium heat. Cook the ground beef and onion until the beef is browned and the onion is softened. Drain any excess grease, then stir in the garlic and cook for 30 seconds. Add the marinara sauce, Italian seasoning, garlic powder, salt, and pepper. Simmer for 5–10 minutes.

4. Prepare the Creamy Cheese Layer
In a medium bowl, combine the softened cream cheese, sour cream, and cottage cheese (or ricotta). Mix until smooth and well blended.

5. Assemble the Casserole
Place half of the butter slices in the bottom of the prepared baking dish. Add half of the cooked spaghetti, then spread the creamy cheese mixture evenly over the pasta. Top with the remaining spaghetti and distribute the remaining butter slices over the top.

6. Add the Sauce and Cheese
Spread the meat sauce evenly over the spaghetti. Sprinkle with the mozzarella and Parmesan cheese, making sure the entire casserole is covered.

7. Bake
Bake uncovered for 35–40 minutes, or until the cheese is melted, bubbly, and lightly golden. If desired, broil for 2–3 minutes for an extra golden top.

8. Rest and Serve
Let the casserole rest for 10 minutes before slicing. Garnish with freshly chopped parsley and serve with garlic bread or a crisp green salad.

Expert Tips

Cook the spaghetti just until al dente to prevent it from becoming soft after baking.
Allow the cream cheese to soften before mixing for a perfectly smooth filling.
Simmer the meat sauce for a few extra minutes to deepen its flavor.
Freshly shred the mozzarella for the best melt and golden finish.
Let the casserole rest before serving so the layers hold together beautifully.
Add a pinch of crushed red pepper flakes for a subtle spicy kick.
Prepare the casserole up to a day in advance and refrigerate until ready to bake.
Leftovers reheat beautifully and often taste even better the next day.
Variations
Swap the Protein: Replace the ground beef with Italian sausage, ground turkey, or ground chicken for a different flavor.
Add Vegetables: Stir sautéed mushrooms, spinach, zucchini, or bell peppers into the meat sauce for extra nutrition.
Make It Extra Cheesy: Add layers of provolone, Monterey Jack, or cheddar cheese along with the mozzarella.
Use Ricotta: Substitute cottage cheese with ricotta for an even richer, creamier filling.
Spice It Up: Add crushed red pepper flakes or diced jalapeños for a little heat.
Try Different Pasta: Penne, rigatoni, or rotini can be used if you don’t have spaghetti.
Add Bacon: Mix crispy bacon crumbles into the cheese filling for a smoky twist.
Lighten It Up: Use lean ground turkey, reduced-fat cream cheese, and light sour cream for a lighter version.
Storage & Reheating
To Store:
Allow the casserole to cool completely before covering or transferring it to an airtight container. Refrigerate for up to 4 days.
To Freeze:
Wrap the casserole tightly with plastic wrap and aluminum foil or store it in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
To Reheat:
Cover with foil and bake at 350°F (175°C) for 20–25 minutes, or microwave individual portions until heated through. Add a spoonful of marinara sauce if needed to keep the pasta moist.
