Recipe Information
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)
Instructions
Preheat your oven to 375°F (190°C).
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.
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.
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.
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.
Return the cooked sausage to the skillet and mix it into the sauce until everything is well combined.
Lightly grease a 9x13-inch baking dish. Transfer the sausage and pepper mixture to the dish, spreading it out evenly.
Sprinkle the shredded mozzarella cheese evenly over the top, followed by the grated Parmesan cheese.
Bake the casserole in the preheated oven for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden on top.
Remove the casserole from the oven and let it cool for 5 minutes. Sprinkle fresh parsley on top for garnish before serving.
Serve warm and enjoy this delicious Italian Sausage and Pepper Casserole with crusty bread or a side salad.
