Instructions

1. Step 1: Preheat the oven to 425°F. In a large bowl, combine 4 Italian sausage links, 1 sliced red bell pepper, 1 sliced yellow bell pepper, 1 sliced yellow onion, and 3 thinly sliced garlic cloves. Drizzle with 2 tablespoons olive oil, then sprinkle 1 teaspoon dried oregano, 1/2 teaspoon dried thyme, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1/4 teaspoon red pepper flakes if using. Toss everything together until evenly coated.
2. Step 2: Spread the mixture evenly on a large rimmed baking sheet in a single layer. Roast in the oven for 25-30 minutes, turning the sausage and vegetables halfway through, until the sausage is browned and cooked through and the peppers and onions are tender and slightly caramelized.
3. Step 3: Remove from the oven and let rest for 5 minutes before serving to allow the flavors to meld and the juices to redistribute.
