Step 1: Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
Step 2: Cook the pasta according to package directions until al dente. Drain well and set aside. Remember to cook it slightly less than you normally would, as it will finish cooking in the oven.
Step 3: While the pasta cooks, heat olive oil in a large skillet or Dutch oven over medium-high heat. Add ground beef and Italian sausage, breaking up the meat with a spoon. Cook until no pink remains, then drain off any excess fat. This is a crucial step for a less greasy Meat Lovers Pizza Pasta Bake.
Step 4: Add the chopped onion to the skillet with the cooked meat and sauté until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.
Step 5: Pour in the crushed tomatoes, tomato sauce, and water (or beef broth). Stir in the Italian seasoning, oregano, and red pepper flakes (if using). Season with salt and pepper to taste. Bring the sauce to a simmer, then reduce heat to low and let it cook for 10-15 minutes, allowing the flavors to meld. This simmering time is important for the depth of flavor in your Meat Lovers Pizza Pasta Bake.
Step 6: Add the cooked and drained pasta to the skillet with the meat sauce. Stir well to ensure all the pasta is evenly coated. Add about half of the pepperoni slices and 2 cups of the shredded mozzarella cheese. Mix thoroughly until combined.
Step 7: Transfer the pasta mixture to the prepared 9x13 inch baking dish, spreading it into an even layer. Top with the remaining 2 cups of shredded mozzarella cheese, the remaining pepperoni slices, and the grated Parmesan cheese. Arrange the pepperoni to your liking for that classic pizza look on your Meat Lovers Pizza Pasta Bake.
Step 8: Bake for 25-30 minutes, or until the cheese is bubbly and golden brown. If desired, you can broil for the last 1-2 minutes to get extra browning on the cheese, but watch it closely to prevent burning.
Step 9: Remove the Meat Lovers Pizza Pasta Bake from the oven and let it rest for 5-10 minutes before serving. This allows the cheese to set and makes for easier serving. Garnish with fresh chopped basil or parsley, if desired. Serve hot and enjoy every hearty bite!
