Ingredients
- 1 pound ground beef
- 1 medium yellow onion, finely diced
- 4 cloves garlic, minced
- One 24-ounce jar marinara sauce
- One 8-ounce can tomato sauce
- 2 teaspoons Italian seasoning
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon red pepper flakes
- 1 pound spaghetti
- 8 ounces cream cheese, softened to room temperature
- 1/2 cup sour cream
- 1/2 cup whole milk
- 1/2 cup grated Parmesan cheese
- 2 cups shredded mozzarella cheese, divided
- 2 tablespoons fresh parsley, chopped (optional)
- 2 tablespoons butter, for greasing the baking dish
Instructions
- Preheat your oven to 350°F. Grease a 9×13-inch baking dish with butter and set aside.
- In a large skillet over medium-high heat, brown the ground beef, breaking it apart as it cooks, about 5-7 minutes until no pink remains. Drain excess fat if necessary.
- Add the diced onion to the beef and cook for 3-4 minutes until softened and fragrant.
- Stir in the minced garlic and cook for another minute until very fragrant.
- Pour in the marinara sauce and tomato sauce, then add Italian seasoning, salt, black pepper, and red pepper flakes. Stir well to combine.
- Reduce heat to low and let the sauce simmer for 10 minutes, stirring occasionally. Taste and adjust seasonings as needed.
- While the sauce simmers, bring a large pot of salted water to a boil. Add the spaghetti and cook according to package directions until al dente, about 9-11 minutes.
- Drain the pasta and set aside, reserving 1/2 cup of pasta water.
- In a medium bowl, combine the softened cream cheese, sour cream, whole milk, and grated Parmesan cheese. Beat with an electric mixer or whisk until smooth and creamy.
- Stir in 1 cup of the shredded mozzarella cheese into the cream cheese mixture until fully incorporated.
- In the prepared baking dish, layer half of the cooked spaghetti in an even layer on the bottom.
- Spread half of the cream cheese mixture over the spaghetti layer, using a spatula to distribute it evenly.
- Top with half of the meat sauce, spreading it gently over the cheese layer.
- Create a second layer by topping with the remaining spaghetti.
- Spread the remaining cream cheese mixture over the second layer of spaghetti.
- Top with the remaining meat sauce, spreading it to cover the cream cheese layer.
- Sprinkle the remaining 1 cup of mozzarella cheese evenly over the top of the casserole.
- Cover the baking dish with aluminum foil and bake for 25 minutes.
- Remove the foil and continue baking for another 10-15 minutes until the cheese is melted, bubbly, and slightly golden on top.
- Remove from the oven and let rest for 5 minutes before serving. Garnish with fresh parsley if desired.
Pro Tips
Freezing Instructions: You can freeze the unbaked casserole for up to 3 months. Wrap it well in plastic wrap and aluminum foil. Thaw overnight in the refrigerator before baking, or bake directly from frozen, adding 20-30 minutes to the cooking time.
Cream Cheese Tips: Make sure your cream cheese is completely softened to room temperature before mixing. This ensures a smooth, lump-free mixture that distributes evenly throughout the casserole. If you forget to soften it, cut it into small cubes and let it sit for 15 minutes.
Meat Sauce Variations: Feel free to customize the meat sauce with ground Italian sausage, ground veal, or a combination of meats. You can also add sautéed mushrooms, bell peppers, or fresh spinach to the sauce for extra vegetables and nutrition.
Cheese Choices: While mozzarella is traditional, you can experiment with other cheeses. Try a mixture of mozzarella and fontina, or add some sharp cheddar for extra flavor depth. Just avoid pre-shredded cheese with anti-caking agents if possible, as fresh-shredded melts more smoothly.
Pasta Texture: Cook your spaghetti just shy of al dente since it will continue cooking in the oven. Overcooked pasta can become mushy in the casserole.
Layering Technique: The key to an evenly cooked casserole is careful, even layering. Use a spatula to spread the cream cheese mixture gently without breaking the pasta underneath.
Serving Suggestions: Pair with a simple green salad dressed with lemon vinaigrette and crusty garlic bread. A glass of red wine complements this dish beautifully. Consider serving with Serious Eats’ side dish ideas for a complete meal.
Leftovers: Store covered in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the entire casserole in a 325°F oven until heated through, about 15-20 minutes.
Baking Dish Size: If using a different size baking dish, adjust the baking time accordingly. A shallower dish will bake faster; a deeper dish will take longer.
