Step 1

Preheat the oven to 350 degrees Fahrenheit. Grease a 9x13-inch baking dish with non-stick spray.

Step 2

In a large skillet over medium-high heat, cook the onion and garlic for 5 minutes or until the onion is translucent. Then, add the ground beef and Italian sausage. Break apart the meat as it cooks. Cook until it's browned and crumbled, about 10 minutes. Drain excess fat.

Step 3

Add the marinara sauce, Italian seasoning, salt, and pepper. Simmer it for 10-15 minutes or until the sauce is thick.

Step 4

Meanwhile, cook the rigatoni pasta according to the package instructions until al dente. Drain the pasta and toss it with meat sauce.

Step 5

Transfer the pasta mixture to the greased baking dish and top it with mozzarella cheese. Cover it with foil and bake it for 20 minutes.

Step 6

Remove the foil and bake it for 10-15 minutes more or until the cheese is melted and bubbly. Let it stand for 5 minutes before serving.

Step 7

Enjoy!
