Step-by-Step Instructions

Cook the pasta: Boil 12 oz of penne or rigatoni in salted water until al dente, about 9 minutes. Drain and set aside. The pasta should have a slight bite, not mushy.
Brown the sausage: In a large skillet over medium heat, cook 1 lb of Italian sausage (casings removed) until browned and crumbly, approximately 7 minutes. Drain excess fat.
Sauté vegetables: Add 1 diced onion and 2 minced garlic cloves to the skillet. Cook until softened and fragrant, about 3 minutes.
Add sauce: Stir in 2 cups marinara sauce and 1 tsp Italian seasoning. Simmer for 5 minutes to meld flavors and slightly thicken.
Combine pasta and sauce: Mix the cooked pasta into the skillet with sausage sauce mixture, ensuring every piece is coated.
Layer cheese: Transfer pasta mixture to a greased 9×13 baking dish. Sprinkle evenly with 1½ cups shredded mozzarella and ½ cup grated Parmesan.
Bake: Preheat the oven to 375°F (190°C) and bake uncovered for 20 minutes or until cheese is melted and bubbly with light golden spots.
Rest and serve: Let rest for 5 minutes before serving. The bake will firm up and be easier to slice.
