Ingredients
- 4 links (about 1 lb) Italian sausage links
- 1 large, sliced into 1/2-inch strips red bell pepper
- 1 large, sliced into 1/2-inch strips yellow bell pepper
- 1 medium, sliced into 1/2-inch strips yellow onion
- 3 cloves, thinly sliced garlic cloves
- 2 tbsp olive oil
- 1 tsp dried oregano
- 1/2 tsp dried thyme
- 1 tsp salt
- 1/2 tsp black pepper
- 1/4 tsp (optional) red pepper flakes
Instructions
- 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.
- 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.
- 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.
