Instructions

1. Step 1: Preheat oven to 400°F. In a large bowl, toss 1 lb Italian sausage links, 1 sliced red bell pepper, 1 sliced green bell pepper, and 1 sliced yellow onion with 3 tbsp olive oil, 4 minced garlic cloves, 1 tsp dried oregano, 1 tsp dried basil, 1 tsp salt, and 1/2 tsp black pepper until evenly coated.
2. Step 2: Arrange the sausage and vegetables on a rimmed baking sheet in a single layer. Roast in the oven for 20 minutes until the sausage starts to brown and vegetables soften.
3. Step 3: Remove the pan from oven and pour 1 cup canned crushed tomatoes evenly over the sausage and peppers. Sprinkle 1 cup shredded mozzarella cheese and 1/4 cup grated Parmesan cheese on top.
4. Step 4: Return to the oven and bake for another 10-12 minutes until cheese melts and bubbles and sausage is cooked through (internal temperature 160°F).
5. Step 5: Let it rest 5 minutes before serving to allow the sauce to thicken and flavors to meld.
