What makes this casserole so irresistible? The combination of spicy Italian sausage with sweet and colorful bell peppers creates a perfect balance of flavors. The dish is not only filling but also versatile and easy to prepare. Plus, casseroles are inherently comforting, making them a go-to choice for family dinners.

Ingredients You’ll Need

Before you start, gather the following fresh and pantry staples:

1 pound Italian sausage (mild or spicy, depending on preference)
3 bell peppers (red, yellow, and green for color)
1 large onion, sliced
3 cloves garlic, minced
1 can (14 oz) crushed tomatoes
1 teaspoon dried oregano
1 teaspoon dried basil
1/2 teaspoon red pepper flakes (optional for extra heat)
2 cups cooked pasta (penne or rigatoni work great)
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
Salt and black pepper to taste
2 tablespoons olive oil

Step-by-Step Instructions

Step 1: Prepare the Ingredients

Slice the bell peppers and onion into thin strips. Mince the garlic. If your Italian sausage is in casings, remove it from the casing for easy crumbling during cooking.

Step 2: Cook the Sausage

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Add the sausage and cook until browned, breaking it into smaller pieces as it cooks. Once fully browned, remove the sausage from the skillet and set aside.

Step 3: Sauté the Vegetables

In the same skillet, add the onions and bell peppers. Cook for 5–7 minutes until softened. Add the garlic and sauté for another 1–2 minutes until fragrant.

Step 4: Combine Sauce and Seasonings

Add the crushed tomatoes, oregano, basil, red pepper flakes (if using), salt, and black pepper. Stir well and let the sauce simmer for 10 minutes to allow the flavors to meld.

Step 5: Assemble the Casserole

Preheat your oven to 375°F (190°C). In a large baking dish, combine the cooked sausage, sautéed vegetables, and tomato sauce. Mix in the cooked pasta, then top with shredded mozzarella and Parmesan cheese.

Step 6: Bake to Perfection

Bake uncovered for 20–25 minutes, or until the cheese is melted, bubbly, and slightly golden. Let the casserole cool for a few minutes before serving.

Tips for the Best Italian Sausage and Pepper Casserole

Choose high-quality sausage: Using fresh, flavorful Italian sausage makes a huge difference in taste.
Use a mix of peppers: Red, yellow, and green peppers not only add color but also a balance of sweetness and texture.
Don’t overcook pasta: Cook pasta just until al dente as it will continue cooking in the oven.
Add fresh herbs: Fresh basil or parsley added before serving can elevate the flavor.
Make it ahead: Prepare the casserole the day before, cover, and refrigerate. Bake it the next day for a convenient, ready-to-eat meal.

Variations You Can Try

Spicy Sausage Casserole: Use hot Italian sausage and add extra red pepper flakes.
Cheese Lovers: Mix in ricotta or provolone for a richer, creamier casserole.
Low-Carb Version: Substitute pasta with zucchini noodles or cauliflower rice.
Vegetarian Option: Replace sausage with plant-based sausage or extra mushrooms and zucchini.
