Preheat the oven to 350°F. Grease a deep dish pie plate. Cook 6 ounces of spaghetti according to the package directions, then drain. Toss the spaghetti with 2 tablespoons melted butter, 2 eggs, and ½ cup parmesan. Press it into a crust in the pie plate.
In a medium bowl, mix 1 cup ricotta cheese, 1 teaspoon parsley, ½ teaspoon oregano, and ½ teaspoon basil.
Spread the ricotta mixture over the spaghetti in the pie plate.
In a large skillet, cook ½ pound ground beef and ½ pound Italian sausage, breaking it into small pieces as it cooks.
When the meat is cooked through, drain the grease. Add 1 (14-ounce) can of diced tomatoes and 2 cups marinara sauce to the skillet and stir to combine.
Pour the meat sauce over the ricotta layer, spreading evenly.
Sprinkle 1 cup mozzarella cheese over the top of the meat sauce. Bake 20-25 minutes, until the cheese is melted and the sauce is bubbly.
If the top browns too quickly, tent a piece of foil over the top of the pie to keep it from burning.
Let sit for ten minutes, then cut into wedges and serve.
