Ingredients

• 1 pound Italian sausage (mild or spicy)
• 2 tablespoons Olive oil
• 1 large Red bell pepper
• 1 large Green bell pepper
• 1 large Yellow bell pepper
• 1 large Onion
• 3 cloves Garlic cloves
• 1 14-ounce can Crushed tomatoes
• 2 tablespoons Tomato paste
• 2 teaspoons Italian seasoning
• 0.5 teaspoons Red pepper flakes (optional)
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 1.5 cups Shredded mozzarella cheese
• 0.5 cups Grated Parmesan cheese
• 2 tablespoons Fresh parsley (for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Slice the red, green, and yellow bell peppers into thin strips. Peel the onion, cut it in half, and slice it into thin strips. Mince the garlic cloves finely.

Step 3

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the Italian sausage and cook until browned, breaking it into small pieces with a spoon, about 5-7 minutes. Remove the cooked sausage from the skillet and set it aside.

Step 4

In the same skillet, add the remaining tablespoon of olive oil. Add the sliced bell peppers and onions, and cook for 5-6 minutes until they soften slightly.

Step 5

Stir in the minced garlic, crushed tomatoes, tomato paste, Italian seasoning, red pepper flakes (if using), salt, and black pepper. Simmer the mixture for 5 minutes, stirring occasionally.

Step 6

Return the cooked sausage to the skillet and mix it into the sauce until everything is well combined.

Step 7

Lightly grease a 9x13-inch baking dish. Transfer the sausage and pepper mixture to the dish, spreading it out evenly.

Step 8

Sprinkle the shredded mozzarella cheese evenly over the top, followed by the grated Parmesan cheese.

Step 9

Bake the casserole in the preheated oven for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden on top.

Step 10

Remove the casserole from the oven and let it cool for 5 minutes. Sprinkle fresh parsley on top for garnish before serving.

Step 11

Serve warm and enjoy this delicious Italian Sausage and Pepper Casserole with crusty bread or a side salad.
