Roasted Italian Sausage Peppers

Featured in: Weeknight Dinners

This dish features Italian sausages roasted to perfection alongside sweet bell peppers and onions, all cooked together on a single sheet pan. Olive oil and herbs like oregano and basil enhance the flavors, while garlic powder and optional red pepper flakes add subtle heat. Roasting at high heat caramelizes the vegetables and crisps the sausages, making cleanup easy. Garnishing with fresh parsley or basil lifts the fresh, vibrant colors and adds a final aromatic touch. Ideal for an easy, gluten-free main course.
