Method
- Preheat your oven to 425 degrees F. Line a large rimmed sheet pan with parchment paper or foil for easier cleanup.
- Slice the sausage links into rounds about 1 inch thick. Slice the bell peppers into 1/2-inch strips and slice the onion the same way. Place everything on the sheet pan.
- Drizzle the olive oil over the sausage and vegetables. Add the minced garlic, Italian seasoning, salt, pepper, and red pepper flakes if using. Toss everything together right on the pan until each piece is coated in oil and seasoning.
- Spread everything out into a single, even layer. This is important: if pieces are stacked or too close together, they will steam instead of roast and you will miss the caramelized edges that make this dish worth making. Use two pans if your pan feels crowded.
- Roast on the center rack for 20 to 25 minutes, flipping everything once at the 15-minute mark. The sausage should be browned and cooked through, and the peppers and onions should have some char at the edges. If anything looks pale at 25 minutes, give it another 3 to 5 minutes.
- Remove the pan from the oven. If using balsamic vinegar, drizzle it over the hot vegetables now and toss quickly. It adds a subtle sweetness that pulls everything together. Taste and adjust salt.
- Serve right from the pan in hoagie rolls, over creamy polenta, on top of cooked pasta, or alongside crusty bread to soak up the pan juices.
Notes
Giving each piece of sausage and vegetable space on the pan is the most important technique here. Overcrowding is the single reason sheet pan dinners come out soft instead of roasted. If your pan looks full, split onto two pans rather than piling everything in.
