Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish.

Boil ziti in salted water for 2 minutes less than package directions (very al dente). Drain and toss with a little oil.

In a large skillet, brown ground beef and sausage over medium-high heat. Add onion and cook until soft. Stir in garlic, tomato paste, and spices.

Add marinara sauce to the meat, bring to a simmer, then reduce heat and cook for 10 minutes.

In a bowl, mix ricotta, egg, 1/2 cup Parmesan, and parsley until smooth.

Combine cooked pasta with the meat sauce. Pour half into the baking dish.

Dollop the ricotta mixture over the pasta layer and sprinkle with 1 cup mozzarella.

Top with remaining pasta mixture. Cover with remaining mozzarella and Parmesan.

Bake covered with foil for 20 minutes. Remove foil and bake 15-20 minutes more until bubbly and golden.

Let rest for 15 minutes before serving to allow sauce to set.
