A simple and quick sheet pan recipe featuring Italian sausage roasted alongside sweet bell peppers and onions, perfect for busy weeknights.

Ingredients

Scale
  • 4 Italian sausage links (about 1 pound), mild or spicy
  • 3 medium bell peppers (red, yellow, green), sliced into strips
  • 1 large yellow onion, sliced into thick rings or half moons
  • 2 tablespoons olive oil
  • 3 cloves garlic, minced or thinly sliced
  • 1 teaspoon Italian seasoning
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • Pinch of red pepper flakes (optional)
  • Handful of fresh parsley, chopped (optional)

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Slice the bell peppers into 1/2-inch wide strips and the onion into thick half moons. Mince or thinly slice the garlic cloves.
  3. In a large mixing bowl, combine the sliced peppers, onions, garlic, olive oil, Italian seasoning, salt, and pepper. Toss well to coat evenly.
  4. Spread the veggie mixture in an even layer on a rimmed 18×13-inch sheet pan, leaving space for the sausage links.
  5. Nestle the Italian sausage links alongside the peppers and onions, spacing them out for even cooking.
  6. Roast in the preheated oven for 20 minutes.
  7. After 20 minutes, use tongs to turn the sausage links and toss the veggies for even browning. Return to the oven for another 10-15 minutes or until the sausage reaches an internal temperature of 160°F (71°C) and the veggies are tender and caramelized.
  8. Remove from the oven and let rest for 5 minutes.
  9. Garnish with fresh parsley if desired and serve hot.

Notes

Do not overcrowd the pan to ensure proper roasting and caramelization. Use room temperature sausage for even cooking. Flip sausage and toss veggies halfway through cooking. Tent with foil if sausage browns too quickly before veggies are tender. Variations include swapping sausage for chicken, turkey, or plant-based options, adding cherry tomatoes or mushrooms, or sprinkling cheese during the last 5 minutes of roasting.
