Step 1

Preheat your oven to 375° Fahrenheit.

Step 2

While the pasta is cooking, brown the ground beef in a large skillet over medium heat. Cook until it's no longer pink, then drain any excess fat.

Step 3

Mix the marinara sauce with the cooked ground beef. Let it simmer for about 5 minutes.

Step 4

In a large baking dish, layer half of the cooked spaghetti, then top it with half of the marinara and beef mixture.

Step 5

Pour half of the Alfredo sauce evenly over the marinara layer.

Step 6

Sprinkle half of the shredded mozzarella cheese and half of the grated Parmesan cheese over the top of the Alfredo sauce.

Step 7

Repeat the layers with the remaining spaghetti, marinara-beef mixture, Alfredo sauce, and cheeses.

Step 8

Bake the dish in the preheated oven for about 20-25 minutes, or until the cheese on top is melted and golden.
