Instructions
Preheat and prep your gear: Set the oven to 375°F (190°C) and grease a 9x13-inch baking dish.
Boil your pasta: In a large pot of very salty boiling water, cook penne until just barely al dente. Drain and set aside.
Brown the meats: In a large skillet over medium-high heat, cook ground beef and Italian sausage until no longer pink. Break up any large chunks with a spoon.
Add vegetables: Stir in the onion, garlic, and green bell pepper. Sauté about 5 minutes, until softened and fragrant.
Season: Add Italian seasoning, red pepper flakes, salt, and black pepper.
Add sauce: Stir in the tomato sauce and diced tomatoes (with juices). Bring to a simmer and cook for 10 minutes.
Layer the casserole: Spread half the cooked penne into the bottom of the baking dish. Sprinkle with 1 cup mozzarella. Top with half the meat sauce.
Add the remaining pasta, 1 cup more mozzarella, and remaining meat sauce.
Cover and bake: Wrap tightly with foil and bake for 30 minutes.
Add final cheese and finish baking: Remove foil, sprinkle remaining 1/2 cup mozzarella and all the cheddar cheese on top. Bake uncovered 10–15 minutes, until cheese is bubbling and golden.
Rest before serving: Let casserole cool for 10 minutes before scooping and serving.
Notes
Storage: Store cooled leftovers in an airtight container in the fridge for up to 5 days or freeze up to 3 months. Reheat individual servings in the microwave or bake the entire casserole at 350°F (175°C) until warmed through.Variations: Use mushrooms or plant-based crumbles for a meatless option. Substitute other hearty pasta shapes like rotini or rigatoni. Vary the cheese with provolone, Monterey Jack, or fontina.
