Ingredients

1½ cups green bell peppers seeded and sliced
1½ cups red bell peppers seeded and sliced
1 large yellow onion thinly sliced
4 large cloves garlic smashed
2 tablespoons olive oil
1 cup tomato sauce
1 tablespoon water
1 small bundle fresh basil or 1 teaspoon dried basil
Salt and black pepper to taste
¼ teaspoon red chili flakes optional
1½ –2 pounds fresh Italian sausage links mild or spicy

Instructions

Preheat the oven to 350°F.
Place the sliced bell peppers, onion, and smashed garlic cloves in a large baking dish. Add olive oil, salt, black pepper, and optional red chili flakes. Toss to coat.
Add tomato sauce, water, and basil. Toss until the vegetables are evenly coated.
Arrange the Italian sausage links in a single layer over the vegetables. Cover with parchment paper, then seal tightly with aluminum foil.
Bake covered for 30 minutes.
Remove the parchment and foil. Bake uncovered for 15 minutes, then turn the sausages and bake for another 15 minutes, or until the internal temperature reaches 160°F for pork sausage or 165°F for poultry sausage.
Broil on low for 3–5 minutes to brown the sausage, watching closely.
Serve with the peppers, onions, and tomato sauce.

Notes

Use mild, sweet, or hot Italian sausage according to your preference.
Cooking times may vary depending on the thickness of the sausage.
The peppers and onions release liquid during baking, creating a flavorful sauce.
Serve in toasted Italian rolls or over pasta.
Refrigerate leftovers for up to 4 days.
