This one-pan Italian sausage with roasted peppers is the weeknight dinner I lean on when I want bold, classic Italian-American flavor without a sink full of dishes. Everything roasts together on a single pan for caramelized peppers, juicy sausage, and a quick pan sauce.
Why you’ll love this one-pan dinner
- Minimal cleanup: one sheet pan does the work.
- Big flavor: peppers and onions caramelize while the sausage browns.
- Flexible: serve it in hoagie rolls, over rice, with pasta, or alongside a salad.
- Great for meal prep: leftovers reheat beautifully.
Ingredients
- 1 1/2 to 2 lb Italian sausage links (sweet or hot)
- 3 bell peppers (mix of red, yellow, orange), sliced into strips
- 1 large yellow onion, sliced
- 3 cloves garlic, thinly sliced
- 2 tbsp olive oil
- 1 tsp kosher salt (plus more to taste)
- 1/2 tsp black pepper
- 1 1/2 tsp Italian seasoning
- 1/2 tsp crushed red pepper flakes (optional)
- 2 tbsp balsamic vinegar (or red wine vinegar)
- Optional to finish: chopped parsley or basil, grated Parmesan
- For serving (optional): toasted hoagie rolls, rice, mashed potatoes, or cooked pasta
How to make one-pan Italian sausage with roasted peppers
1) Heat the oven. Preheat to 425°F. Line a rimmed sheet pan with foil or parchment for easier cleanup.
2) Season the vegetables. Add sliced peppers, onion, and garlic to the pan. Drizzle with olive oil and toss with salt, pepper, Italian seasoning, and red pepper flakes (if using). Spread into an even layer.
3) Add sausage and roast. Nestle the sausage links among the veggies. Roast for 20 minutes.
4) Flip and finish roasting. Flip the sausages and stir the peppers/onions. Roast 10–15 minutes more, or until sausages are browned and cooked through (160°F for pork; 165°F for chicken/turkey).
5) Add vinegar and serve. Drizzle balsamic vinegar over the hot pan and toss everything to coat. Taste and add a pinch more salt if needed. Serve immediately.
Tips for the best results
- Slice evenly: keep pepper and onion strips similar thickness so they roast at the same pace.
- Don’t overcrowd: if your pan is packed, use two pans so the vegetables roast instead of steam.
- Use a thermometer: it’s the easiest way to prevent dry sausage.
- Want extra browning? Broil for 1–2 minutes at the end, watching closely.
Serving ideas
- Sausage and pepper sandwiches: pile into toasted hoagie rolls; add provolone if you like.
- Over pasta: toss with marinara or a splash of pasta water and olive oil.
- Low-carb: serve over cauliflower rice or with a big Italian salad.
- Breakfast remix: reheat and top with a fried egg.
Storage and reheating
- Refrigerate: store in an airtight container up to 4 days.
- Reheat: warm in a skillet over medium heat or in the microwave until hot.
- Freeze: freeze portions up to 2 months; thaw overnight in the fridge before reheating.
