Ingredients

Scale

Meat

  • 1 pound Italian sausage

Vegetables

  • 2 bell peppers (red and green), sliced
  • 1 onion, chopped
  • 3 cloves garlic, minced

Tomato Base

  • 1 can (14.5 oz) diced tomatoes
  • 1 can (8 oz) tomato sauce

Seasonings & Cheese

  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste
  • 1 cup shredded mozzarella cheese

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to get it ready for baking the casserole.
  2. Cook Sausage: In a large skillet over medium heat, cook the Italian sausage until it browns evenly, breaking it up as it cooks to ensure thorough cooking.
  3. Sauté Vegetables: Add the sliced bell peppers, chopped onion, and minced garlic to the skillet with the sausage. Sauté until the vegetables become tender and fragrant, about 5-7 minutes.
  4. Add Tomato Ingredients: Stir in the diced tomatoes, tomato sauce, Italian seasoning, salt, and pepper into the skillet. Mix well to combine all flavors evenly.
  5. Transfer to Casserole: Pour the sausage and vegetable mixture into a casserole dish, spreading it evenly.
  6. Add Cheese and Bake: Sprinkle the shredded mozzarella cheese on top of the mixture. Bake in the preheated oven for 25-30 minutes or until the cheese is bubbly and golden brown.
  7. Cool and Serve: Remove the casserole from the oven and allow it to cool a few minutes before serving to let the flavors settle and to avoid burning yourself.

Notes

  • You can use spicy or mild Italian sausage depending on your heat preference.
  • For a lower-fat option, substitute turkey sausage or lean sausage varieties.
  • Add extra vegetables like mushrooms or zucchini for added nutrition and flavor.
  • If you like a stronger cheese flavor, mix mozzarella with Parmesan or provolone cheese.
  • Serve with crusty bread or over cooked pasta for a more filling meal.
