Creating Baked Rigatoni is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C). Grease a large baking dish with cooking spray or oil.
2. Cook the Pasta: In a large pot, cook the rigatoni according to package instructions until al dente. Drain and set aside.
3. Sauté the Aromatics: In a skillet, heat olive oil over medium heat. Add the chopped onion and sauté until translucent. Stir in the minced garlic and cook for 1-2 minutes.
4. Brown the Meat: Add the ground beef (or sausage) to the skillet. Cook until browned and fully cooked through. Drain any excess fat.
5. Make the Sauce: Stir in the crushed tomatoes, basil, oregano, salt, and pepper. Simmer for 10 minutes, allowing the flavors to meld.
6. Mix Cheese Filling: In a bowl, combine the ricotta cheese, 1 cup of mozzarella cheese, Parmesan cheese, egg, and a pinch of salt. Mix until smooth.
7. Combine Pasta and Sauce: In a large bowl, mix the cooked rigatoni with the sauce, ensuring all pasta is well-coated.
8. Layer the Casserole: In the greased baking dish, spread half of the pasta mixture. Spoon half of the cheese mixture on top. Repeat with remaining pasta and cheese.
9. Top with Mozzarella: Sprinkle the remaining mozzarella cheese over the top layer. Cover with aluminum foil.
10. Bake: Bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes until the cheese is golden and bubbly.
11. Rest: Remove the dish from the oven. Let it rest for 10-15 minutes before serving to allow the flavors to settle.
