Ingredients
For the Casserole

- ¼ cup tomato paste
- ¼ cup water
- 2 teaspoons Italian seasoning
- 4 large bell peppers (various colors; seeds removed, sliced into ½-inch-long pieces)

How to Make Cheesy Italian Sausage and Bell Pepper Casserole
Step 1: Preheat the Oven
Preheat your oven to 375° Fahrenheit. Spray a 9×13 baking dish with cooking spray and set it aside. Cut the sausage into 1-inch pieces.
Step 2: Brown the Sausage
Heat a large skillet over medium heat. Add the cut sausage pieces and cook for about 10 minutes, stirring occasionally until they are browned but not fully cooked through. Drain any liquid from the skillet.
Step 3: Prepare the Sauce
In a small bowl, whisk together the tomato paste, water, and Italian seasoning until well combined. Set this mixture aside.
Step 4: Combine Ingredients
In a large bowl (or in the skillet if there’s enough space), mix together the browned sausage, sliced bell peppers, and onions. Pour the tomato sauce over this mixture and stir well to coat everything evenly.
Step 5: Layer in Baking Dish
Transfer half of the sausage mixture to your greased baking dish. Top this layer with 1 cup of shredded mozzarella cheese. Spread the remaining sausage mixture on top of the cheese and cover the baking dish with foil.
Step 6: Bake Covered
Place the covered baking dish in your preheated oven and bake for 30 minutes. After this time, remove the foil and stir the casserole well. Top with the remaining 1 cup of mozzarella cheese and return it to the oven uncovered.
Step 7: Final Bake
Bake uncovered for an additional 10 minutes or until the sausage is no longer pink and peppers are tender. Remove from oven and serve hot.

Common Mistakes to Avoid

- Skipping the seasonings: Not adding enough Italian seasoning can result in bland flavors. Be sure to mix in the right amount for a rich taste.
- Overcooking the sausage: Cooking the sausage too long before baking can lead to dryness. Aim for it to be browned but not fully cooked through.
- Ignoring vegetable sizes: Cutting bell peppers and onions into uneven sizes can lead to uneven cooking. Try to slice them all consistently for even tenderness.
- Not draining excess liquid: Allowing extra liquid from the sausage to remain can make your casserole watery. Drain any excess before mixing with veggies.
