FAQs
Can I use ground beef instead of Italian sausage?
Yes, ground beef or turkey can be substituted for Italian sausage. For extra flavor, add Italian seasoning and a bit of fennel seed to mimic sausage spices.
How do I know when the mostaccioli pasta is al dente?
Al dente means the pasta is cooked but still firm to the bite. Start checking the pasta for doneness a minute or two before the package’s recommended cooking time by tasting a piece.

Ingredients
Pasta
- 16 oz mostaccioli pasta
Meat
- 1 lb Italian sausage
Vegetables
- 1 large green bell pepper, chopped
- 1 medium onion, chopped
- 3 cloves garlic, minced
Sauce & Cheese
- 4–5 cups marinara sauce
- 2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
Seasonings & Garnish
- Kosher salt, to taste
- Freshly ground black pepper, to taste
- Fresh parsley, chopped (optional garnish)
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it’s ready for baking the assembled dish.
- Cook Pasta: Boil a large pot of salted water and cook the mostaccioli pasta until al dente. Drain well and set aside to prevent overcooking during baking.
- Brown Sausage: In a large skillet over medium heat, cook the Italian sausage until browned, breaking it into crumbles for even cooking. Drain excess grease and transfer the sausage to a plate.
- Sauté Vegetables: In the same skillet, sauté chopped green bell pepper and onion until they soften, enhancing their sweetness and flavor. Add minced garlic and cook for an additional minute until fragrant, but not burnt.
- Combine Ingredients: In a large baking dish, mix the cooked pasta, browned sausage, sautéed vegetables, and marinara sauce. Season with kosher salt and freshly ground black pepper to taste. Gently combine everything to evenly distribute flavors without breaking pasta.
- Add Cheese Topping: Evenly sprinkle shredded mozzarella cheese and grated Parmesan cheese over the top of the mixture to create a deliciously cheesy crust after baking.
- Bake: Place the baking dish in the preheated oven and bake for 25 to 30 minutes, until the cheese topping is melted, bubbly, and lightly golden brown.
- Rest and Garnish: Remove from the oven and let the baked mostaccioli rest for 5 minutes to set. Garnish with freshly chopped parsley if desired before serving.
Notes
- Cooking the pasta al dente is key to avoid a mushy texture after baking.
- Drain excess grease from sausage to keep the dish healthy and prevent it from being oily.
- You can use turkey sausage for a leaner option.
- If marinara sauce is too thick, thin with a splash of water or broth to your desired consistency.
- Garnish with fresh parsley for a burst of color and mild herbal flavor.
