Ingredients
  

Equipment

  • Rimmed sheet pan: allows high-heat roasting without juices spilling
  • Parchment paper or foil: for easy cleanup and better browning
  • Sharp knife: ensures even slicing so everything roasts at the same rate
  • Large mixing bowl for evenly coating the sausage and vegetables

Method
 

  1. Preheat oven to 425°F. Line a rimmed sheet pan with parchment paper or foil.
  2. Slice sausage into 2-inch pieces. Slice peppers into thick strips and onions into wedges.
  3. Add sausage, peppers, and onions to a large bowl. Drizzle with olive oil and sprinkle with Italian seasoning, garlic powder, and black pepper. Toss until evenly coated.
  4. Spread everything evenly on the prepared sheet pan. Make sure the sausage and vegetables are in a single layer with space between them.
  5. Roast on the middle rack in the oven for 15 minutes, then flip sausage pieces and stir vegetables.
  6. Return to the oven and roast for another 12–15 minutes, until the sausage is fully cooked and the vegetables are tender with caramelized edges.
  7. Remove from the oven and finish with red pepper flakes or a light drizzle of balsamic glaze if desired. Serve hot.

Notes

  • No salt? This recipe does not call for added salt because the sausage already contains enough seasoning. Taste after roasting and add salt only if needed to taste.
  • Spacing matters. Overcrowding the pan will steam the vegetables instead of roasting them. Use two pans if needed.
  • Thicker onion slices hold their shape and caramelize without burning.
  • Chicken sausage works well in this recipe. If using pre-cooked sausage, reduce cook time by about 5 minutes.
  • Meal prep friendly: Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • Serving ideas: Serve over rice, polenta, or mashed potatoes, or pile into hoagie rolls for sausage and pepper sandwiches.
  • Make it low-carb: Serve as is or over cauliflower rice.
