Ingredients

For the Pasta & Sausage

• 12 ounces (340g) rigatoni pasta – Rigatoni's ridges and wide tubes hold onto the rich marinara sauce and melted cheese, making it the perfect pasta for this hearty bake.

• 1 pound (450g) Italian sausage (mild or hot), casings removed – Mild sausage creates a classic family-friendly flavor, while hot Italian sausage adds a spicy kick.

• 1 tablespoon olive oil – Helps sauté the vegetables and prevents the sausage from sticking if it's on the leaner side.

• 1 medium onion, thinly sliced – Adds natural sweetness and savory depth as it cooks.

• 1 red bell pepper, sliced – Brings a sweet, colorful flavor that pairs perfectly with the sausage.

• 1 yellow bell pepper, sliced – Adds another layer of sweetness and bright color to the casserole.

• 3 garlic cloves, minced – Fresh garlic enhances the Italian-inspired flavor throughout the sauce.

For the Sauce

• 1 jar (24 ounces / 680g) marinara sauce – A good-quality marinara creates a rich, flavorful base. Homemade marinara works beautifully as well.

• ½ cup (120ml) chicken broth or water – Loosens the sauce slightly so it coats every piece of pasta while baking.

• 1 teaspoon Italian seasoning – Adds classic herb flavor with oregano, basil, and other Italian herbs.

• ½ teaspoon crushed red pepper flakes (optional) – Adds gentle heat without overpowering the dish.

• Salt and freshly ground black pepper, to taste – Adjust the seasoning after tasting, since sausage and Parmesan already add saltiness.

For the Topping

• 2 cups (225g) shredded mozzarella cheese – Melts into a bubbly, golden topping that makes the casserole irresistibly cheesy.

• ½ cup (50g) grated Parmesan cheese – Adds a rich, nutty finish and helps create a beautifully browned top.

• Fresh basil, chopped (optional, for garnish) – Adds a fresh burst of color and bright flavor just before serving.

Ingredient Note: Use a good-quality Italian sausage since it's the main source of flavor in this casserole. Mild sausage keeps the dish family-friendly, while hot Italian sausage adds a pleasant kick. Freshly shredded mozzarella also melts more smoothly than pre-shredded cheese for the best cheesy topping.

Instructions

1. Cook the pasta. Preheat your oven to 375°F (190°C). Bring a large pot of generously salted water to a boil and cook the rigatoni until just shy of al dente, about 1–2 minutes less than the package directions. The pasta will continue cooking in the oven. Drain and set aside.

2. Brown the sausage. While the pasta cooks, heat the olive oil in a large skillet over medium-high heat. Add the Italian sausage and cook for 6–8 minutes, breaking it into bite-sized pieces, until browned and fully cooked.

3. Sauté the vegetables. Add the sliced onion, red bell pepper, and yellow bell pepper to the skillet. Cook for 6–7 minutes, stirring occasionally, until the vegetables begin to soften. Stir in the minced garlic and cook for another 30–60 seconds, just until fragrant.

4. Make the sauce. Stir the marinara sauce, chicken broth, Italian seasoning, crushed red pepper flakes (if using), salt, and black pepper into the skillet. Bring the sauce to a gentle simmer and cook for about 5 minutes so the flavors can blend.

5. Combine the pasta and sauce. Add the cooked rigatoni to the skillet and gently toss until every piece of pasta is evenly coated with the sausage, peppers, and marinara sauce.

6. Assemble the casserole. Spread half of the pasta mixture into a lightly greased 9×13-inch baking dish. Sprinkle with half of the mozzarella and half of the Parmesan cheese. Add the remaining pasta mixture, then top evenly with the remaining mozzarella and Parmesan.

7. Bake until bubbly. Cover the baking dish with aluminum foil and bake for 20 minutes. Remove the foil and continue baking for 10–12 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.

8. Rest and serve. Let the casserole rest for 5–10 minutes before serving to help it set. Garnish with fresh basil, if desired, and serve warm with garlic bread, a crisp green salad, or your favorite Italian-inspired side dish.

Troubleshooting

My pasta turned mushy.

The pasta was likely overcooked before baking. Cook it just shy of al dente so it finishes cooking in the oven.

My casserole looks dry.

Add a splash of chicken broth or marinara before baking if the mixture seems dry.

My cheese browned too quickly.

Keep the casserole covered for most of the baking time and uncover only during the last 10–12 minutes.

My casserole won't hold together.

Let it rest for at least 5 minutes before serving.

Tips & Variations

Tips

• Slightly undercook the pasta.

• Brown the sausage well.

• Let the casserole rest before serving.

• Use freshly shredded mozzarella.

Variations

• Use hot Italian sausage for extra heat.

• Add sliced mushrooms for more savory flavor.

• Stir fresh spinach into the sauce before baking.

• Make it extra cheesy with provolone or fontina.

• Swap in turkey or chicken sausage for a lighter version.

Make-Ahead & Storage

Sausage & Peppers Rigatoni Bake is an excellent make-ahead meal. Assemble the casserole up to 24 hours in advance, cover, and refrigerate until ready to bake. Leftovers keep well in an airtight container in the refrigerator for up to 4 days and reheat beautifully in the microwave or oven. You can also freeze the baked or unbaked casserole for up to 3 months. Thaw overnight in the refrigerator before reheating or baking for the best texture.

FAQ

Can I use a different type of pasta?

Yes! Penne, ziti, or rotini all work well. Just make sure to slightly undercook the pasta since it finishes baking in the oven.

Should I use mild or hot Italian sausage?

Either works. Mild gives a classic flavor, while hot adds a little kick. You can also mix the two for a balanced heat.

What vegetables work well besides peppers?

Mushrooms, zucchini, spinach, or cherry tomatoes make great additions or swaps. Just sauté them with the peppers.

How do I make this recipe spicier?

Use hot Italian sausage and add extra crushed red pepper flakes to the sauce.

Can I use turkey or chicken sausage instead?

Yes—swap in any ground poultry sausage. It’s lighter but still flavorful.
