Preheat your oven to 375°F. Cook the rigatoni pasta according to package directions until al dente. Drain and set aside. The pasta will finish cooking in the oven, so don't overcook it now.

In a large oven-safe skillet over medium-high heat, brown the ground beef with the chopped onion. Season with salt, pepper, paprika, Italian seasoning, and red pepper flakes while cooking, breaking up the meat as it browns.

Once the beef is fully cooked, drain any excess grease. Add the minced garlic and cook for 30 seconds until fragrant, then stir in the entire jar of marinara sauce. Let it simmer for 2-3 minutes.

Add the cooked rigatoni to the skillet and stir well to coat all the pasta with the meat sauce. Make sure everything is evenly distributed throughout the pan.

Drop spoonfuls of ricotta cheese evenly throughout the skillet, spreading them out so every bite gets some creamy cheese. Don't stir it in - just let the dollops sit on top.

Sprinkle the mozzarella cheese evenly over the entire skillet. Bake for 10-15 minutes until the cheese is melted and bubbly. Remove from oven, top with Parmesan cheese and dried parsley, then serve hot.
