Fabian’s Budget Tip: Stretch the beef without losing flavor: Use 3/4 pound (340 g) ground beef instead of 1 pound (450 g) and add an extra 1 cup (240 ml) marinara sauce. The casserole still tastes hearty because the garlic, sauce, and cheese carry the flavor.
Ingredients (Serves 4)
- 12 ounces (340 g) spaghetti
- 1 pound (450 g) ground beef
- 3 cups (720 ml) marinara sauce
- 3 garlic cloves (about 9 g), minced
- 8 ounces (225 g) cream cheese, softened
- 1 cup (225 g) cottage cheese
- 1/2 cup (120 g) sour cream
- 2 cups (225 g) shredded mozzarella cheese
- 1/2 cup (50 g) grated parmesan cheese
- 1 teaspoon (6 g) fine salt, divided, or to taste
- 1/2 teaspoon (1 g) black pepper
Step-by-Step Instructions
1. Heat the Oven and Cook the Spaghetti
Heat the oven to 375°F (190°C). Bring a large pot of salted water to a rolling boil. Add the spaghetti and cook it 2 minutes less than the package directions. The noodles should bend but still feel firm in the center. Drain well so the casserole does not turn watery.
2. Brown the Beef and Garlic
Set a large skillet over medium heat. Add the ground beef, 1/2 teaspoon salt, and black pepper. Cook until the beef breaks into small crumbles and no pink color remains. Stir in the garlic during the last minute. The kitchen should smell warm and savory, not sharp or burnt. Drain extra fat if the skillet looks greasy.
3. Build the Meat Sauce
Pour the marinara sauce into the skillet with the beef. Stir until the sauce coats every crumble. Let it bubble gently for 3 to 5 minutes, just until it looks glossy and smells rich. Taste and add the remaining salt if needed.
4. Mix the Creamy Cheese Layer
In a medium bowl, stir the softened cream cheese, cottage cheese, and sour cream until thick and creamy. A few small cottage cheese curds are fine. The mixture should spread easily, like a rich pasta filling.
5. Layer the Casserole
Spoon a thin layer of meat sauce into a 9 by 13 inch baking dish. Add half of the cooked spaghetti. Spread half of the creamy cheese mixture over the pasta. Spoon over half of the meat sauce. Repeat with the remaining spaghetti, creamy cheese mixture, and meat sauce.
6. Add Cheese and Bake Until Bubbling
Sprinkle the mozzarella over the top, then finish with parmesan. Bake uncovered for 25 to 30 minutes. Look for bubbling sauce around the edges and melted cheese with light golden spots on top.
7. Rest Before Serving
Let the casserole rest for 10 minutes before slicing. The layers will settle, the cheese will thicken, and each serving will hold together better on the plate.
Expert Troubleshooting & FAQs
Can I make million dollar spaghetti casserole ahead of time?
Yes. Assemble the casserole, cover it, and refrigerate it for up to 24 hours. Bake it straight from the fridge and add about 10 extra minutes, or until the center is hot and the edges bubble.
Why did my casserole turn watery?
The most common cause is wet pasta or thin sauce. Drain the spaghetti well, simmer the meat sauce for a few minutes, and let the baked casserole rest before cutting.
Can I use ricotta instead of cottage cheese?
Yes. Ricotta gives a smoother texture, while cottage cheese gives a lighter, tangier bite. Use the same amount and mix it with the cream cheese and sour cream.
What should I do if the cream cheese looks lumpy?
Let the cream cheese soften at room temperature before mixing. If it still looks lumpy, press it against the side of the bowl with a spoon until it blends into the sour cream.
Can I freeze leftovers?
Yes. Cool the casserole fully, then portion it into freezer-safe containers. Freeze for up to 2 months. Thaw overnight in the fridge and reheat until the sauce bubbles and the cheese softens.
