Before you start

Before beginning, ensure all ingredients are measured and ready to go. Preheat your oven to 375°F (190°C) so that it reaches the correct temperature by the time the assembly is complete.

Have your large pot for boiling the pasta, a colander for draining, and a skillet for the meat sauce ready on your workspace. Clearing the counter space will help you assemble the dish efficiently once the pasta and sauce are ready for the oven.

Ingredients at a glance (5)
  • 1 lb rigatoni pasta
  • 1 lb ground beef
  • 24 oz marinara sauce
  • 3 cups shredded mozzarella cheese
  • 4 oz pepperoni slices

Instructions

Cooking the base components

  1. Prepare the pasta and sauce
    Bring a large pot of salted water to a boil and cook the rigatoni until al dente. In a large skillet, brown the ground beef over medium heat until cooked through to 160°F (71°C). Drain excess fat if necessary and stir in the marinara sauce, simmering for 5 minutes.
    Look for The sauce should be simmering and fragrant.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Ensure the pasta is slightly firm as it will continue cooking in the oven.

The sauce should be thick, rich, and aromatic, with the ground beef fully browned and integrated into the tomato base. The rigatoni should be cooked to an al dente texture, meaning it is tender but still offers a slight resistance when bitten. Once the pasta is drained and the sauce is simmering, everything is ready for the final assembly stage.

Assembling the casserole

  1. Assemble the bake
    Preheat your oven to 375°F (190°C). Combine the cooked pasta with the meat sauce in the skillet or a large mixing bowl. Transfer the mixture into a 9x13 inch baking dish, spreading it out evenly. Top the pasta with the shredded mozzarella cheese and arrange the pepperoni slices across the surface.
    Look for The surface should be completely covered with cheese and pepperoni.
    Tip Distribute the cheese evenly to ensure every bite is perfectly gooey.

The pasta and meat sauce should be thoroughly combined so that each rigatoni tube is coated in the savory mixture. The mixture should be spread evenly across the baking dish to ensure uniform cooking. The top layer of mozzarella and pepperoni should be distributed to cover the entire surface, providing a consistent cheesy and flavorful crust for the bake.

Baking to golden perfection

  1. Bake until golden
    Place the baking dish in the preheated oven and bake for 15 to 20 minutes, or until the cheese is melted, bubbly, and slightly golden brown. Remove the dish from the oven and allow it to rest for 5 minutes before serving to let the sauce set slightly.
    Look for The cheese should be bubbly and golden brown.
    Tip Keep an eye on the pepperoni to ensure it reaches a crisp texture.

The final result should feature a bubbly, molten cheese layer with crispy pepperoni edges. The pasta should be tender and hot, with the sauce having thickened slightly to bind the dish together.

Once the cheese has turned a light, appetizing golden brown, remove the dish from the oven and allow it to rest briefly before serving to ensure the best possible texture.

Common mistakes

Avoid overcooking the pasta in the boiling water, as it will continue to cook in the oven; aim for al dente so it maintains a pleasant bite. Do not crowd the baking dish too much, as this can lead to uneven heating and can prevent the cheese from browning correctly.

Additionally, be sure to brown the ground beef thoroughly at the start, as this is the primary source of savory flavor in the sauce, and drain any excess fat to prevent the final dish from feeling greasy.

How to tell it’s done

The pasta bake is done when the cheese is completely melted, bubbling across the entire surface of the dish, and showing light golden-brown spots in areas where the heat has been most intense. The pepperoni should look slightly curled and crisp.

Ensure the internal temperature of the dish is hot throughout, and let it rest for 5 minutes to allow the sauce to thicken slightly, which makes serving much easier and ensures the layers stay together.
