  • 16 ounces mostaccioli pasta
  • 1 lb bulk Italian sausage
  • 1 large green pepper, seeded, veined, and chopped
  • 1 medium onion, chopped
  • 3 cloves garlic, minced
  • 4-5 cups marinara sauce or tomato sauce
  • 2 cups shredded mozzarella
  • 1/2 cup grated parmesan cheese
  • Kosher salt and fresh ground black pepper, to taste


  1. Preheat the Oven:
    • Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish and set aside.
  2. Cook the Pasta:
    • Bring a large pot of salted water to a boil. Cook the mostaccioli pasta according to the package instructions until al dente. Drain and set aside.
  3. Prepare the Sausage and Vegetables:
    • In a large skillet, cook the Italian sausage over medium heat until browned and cooked through, breaking it apart with a wooden spoon as it cooks. Once cooked, transfer the sausage to a plate lined with paper towels to drain excess grease.
    • In the same skillet, add the chopped green pepper, onion, and minced garlic. Cook until the vegetables are softened, about 5-7 minutes.
  4. Combine Pasta, Sauce, and Ingredients:
    • In the prepared baking dish, combine the cooked mostaccioli pasta, cooked Italian sausage, sautéed vegetables, and marinara sauce. Mix until everything is well combined.
  5. Add Cheese:
    • Sprinkle the shredded mozzarella cheese evenly over the top of the pasta mixture. Then, sprinkle the grated parmesan cheese on top.
  6. Bake to Perfection:
    • Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.
  7. Serve and Enjoy:
    • Remove the foil and bake for an additional 5-10 minutes, until the cheese is golden brown and bubbly. Remove from the oven and let it cool for a few minutes before serving. Serve hot and enjoy!

Cook’s Notes and Variations:

  • Customize the Meat:
    • Substitute Italian sausage with ground beef, ground turkey, or ground chicken for a different flavor profile.
  • Add More Veggies:
    • Incorporate additional vegetables such as mushrooms, zucchini, or spinach for added texture and nutrition.
  • Spice it Up:
    • Add crushed red pepper flakes or Italian seasoning to the pasta mixture for a kick of heat and extra flavor.
  • Make it Vegetarian:
    • Omit the Italian sausage and add extra vegetables or meatless sausage crumbles for a vegetarian version of this dish.
