Step-by-Step Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
- Cook the pasta: Bring a large pot of salted water to a boil. Add the mostaccioli and cook according to package directions until al dente. Drain the pasta, reserving about 1/2 cup of the pasta water, and set aside.
- Brown the meat and aromatics: While the pasta is cooking, heat a large skillet over medium-high heat. Add the ground beef or Italian sausage and cook, breaking it up with a spoon, until browned. Drain off any excess grease. Add the chopped onion to the skillet and cook until softened, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.
- Make the tomato sauce: Pour the crushed tomatoes and tomato sauce into the skillet with the meat and onions. Add the dried oregano, dried basil, salt, black pepper, and red pepper flakes (if using). Stir to combine. Bring the sauce to a simmer, then reduce the heat and let it cook for at least 10 minutes, allowing the flavors to meld.
- Prepare the ricotta mixture: In a medium bowl, combine the ricotta cheese, lightly beaten egg, and 1/4 cup grated Parmesan cheese. Mix well until smooth and creamy.
- Assemble the bake: In the same pot you used to cook the pasta (or a large mixing bowl), combine the drained mostaccioli with about half of the tomato meat sauce. Stir gently to coat the pasta evenly.
- Layer the dish: Spread half of the saucy pasta mixture evenly into the prepared baking dish. Dollop spoonfuls of the ricotta mixture evenly over the pasta layer. Sprinkle about half of the shredded mozzarella cheese over the ricotta.
- Add the remaining pasta: Top with the remaining saucy pasta mixture, spreading it evenly. Pour the remaining tomato meat sauce over the top layer of pasta, ensuring complete coverage.
- Finish with cheese: Sprinkle the remaining mozzarella cheese and a little extra grated Parmesan cheese evenly over the top.
- Bake: Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 20 minutes.
- Brown the cheese: Remove the foil and bake for another 10-15 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
- Rest and serve: Let the Oven Baked Mostaccioli rest for 5-10 minutes before serving. This allows the pasta to set slightly, making it easier to serve and preventing it from being too watery. Serve hot.

Storing and Reheating Tips
Leftover Oven Baked Mostaccioli can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, you can freeze the baked pasta. Allow the dish to cool completely before transferring it to freezer-safe containers or wrapping it tightly in plastic wrap and then aluminum foil. Frozen mostaccioli will keep for 2-3 months.
To reheat, you have a few options. For a single serving, scoop out a portion and microwave it on medium power, covered, until heated through. For larger portions, place the refrigerated or thawed casserole in a baking dish, cover with foil, and reheat in a 350°F (175°C) oven for 20-25 minutes, or until hot and bubbly. If reheating from frozen, allow extra baking time, likely 45-60 minutes, and remove the foil for the last 10-15 minutes to ensure the cheese is nicely melted. You can also add a splash of water or broth before reheating to help keep the pasta moist.
