Ingredients

For the Spaghetti

1 pound spaghetti noodles
2 tablespoons olive oil
1 teaspoon salt for pasta water

For the Meat Sauce

2 pounds ground beef
1 medium onion, finely chopped
4 cloves garlic, minced
1 can (28 ounces) crushed tomatoes
2 tablespoons tomato paste
1 cup marinara sauce
1 teaspoon Italian seasoning
1 teaspoon dried oregano
1 teaspoon paprika
½ teaspoon black pepper
Salt to taste
½ teaspoon red pepper flakes (optional)
Fresh basil or parsley

For the Cheese Layer

2 cups mozzarella cheese, shredded
1 cup Parmesan cheese, grated
1 cup ricotta cheese or cream cheese (optional)
2 tablespoons chopped parsley

Step-by-Step Instructions

Step 1: Prepare the Pasta

Bring a large pot of salted water to a boil.

Add spaghetti noodles and cook until slightly less than fully done according to package instructions.

The pasta will continue cooking in the oven, so keeping it slightly firm prevents it from becoming too soft.

Drain the spaghetti and toss lightly with olive oil to prevent sticking.

Set aside while preparing the sauce.

Step 2: Prepare the Meat Sauce

Heat a large skillet over medium heat.

Add ground beef and cook until browned, breaking it apart with a spoon as it cooks.

Once the beef is browned, drain any excess grease if needed.

Add chopped onions and cook until softened and slightly golden.

Add minced garlic and cook for about 30 seconds until fragrant.

Stir in tomato paste and cook briefly. This helps deepen the tomato flavor.

Add crushed tomatoes, marinara sauce, Italian seasoning, oregano, paprika, salt, black pepper, and red pepper flakes if using.

Allow the sauce to simmer for 15–20 minutes.

Slow cooking the sauce helps the flavors combine and creates a richer taste.

Step 3: Combine the Spaghetti and Sauce

Add the cooked spaghetti into the meat sauce.

Gently toss until every strand of pasta is coated with the flavorful sauce.

This ensures the pasta absorbs the sauce instead of having it only on top.

For extra creaminess, mix in ricotta cheese or cream cheese before baking.

Step 4: Assemble the Casserole

Preheat the oven to 375°F (190°C).

Lightly grease a baking dish.

Add half of the spaghetti mixture into the dish.

Sprinkle a layer of mozzarella and Parmesan cheese.

Add the remaining spaghetti mixture.

Top generously with the remaining cheese.

The layered approach creates a delicious cheesy texture throughout the casserole.

Step 5: Bake Until Golden and Delicious

Cover the baking dish with foil and bake for approximately 20 minutes.

Remove the foil and continue baking for another 10–15 minutes until the cheese becomes melted, bubbly, and lightly golden.

For an extra browned cheese topping, place it under the broiler for 1–2 minutes, watching carefully.

Allow the baked spaghetti to rest for 5–10 minutes before serving.

This helps the layers set and makes serving easier.

Step 6: Garnish and Serve

Finish with freshly chopped parsley or basil.

Serve warm with extra Parmesan cheese if desired.

The melted cheese, savory meat sauce, and tender spaghetti create the perfect comfort food experience.
