Sausage and peppers is one of those Italian-American classics that has been feeding crowds at street fairs, sandwich shops and Sunday tables for generations — and the sheet pan version might be the easiest way ever invented to make it. Everything roasts together on a single pan: the sausages brown and baste the peppers, onions and potatoes with their savory juices, the vegetables soften and caramelize at the edges, and the whole kitchen smells like you have been cooking all afternoon instead of for fifteen minutes.
What we love most is how the pan adapts to the night. Pile the sausage and vegetables into toasted hoagie rolls with a slice of provolone for proper sandwiches, spoon them over creamy polenta or buttered rice for a sit-down dinner, or eat them straight off the pan with a green salad when you are keeping things lighter. However it lands on the table, there is exactly one pan to wash, and that pan does most of the work while you are free to do anything else.
Use sweet Italian sausage for a mild, fennel-scented pan, hot sausage if your house likes a little fire, or a mix of both so everyone can pick a favorite. The vegetables are flexible too — the peppers and onions are non-negotiable, but the little potatoes can give way to chunks of zucchini in summer or wedges of sweet potato in the fall.
Cut for even roasting
A sheet pan dinner is only as good as its knife work. The potatoes are the slowpokes of the pan, so cut them small — halves for baby potatoes, three-quarter-inch chunks for larger ones — and give them a ten-minute head start in the oven while you slice the peppers and onions. Peppers cut into strips about half an inch wide soften and char at the edges in the same time the sausage needs; onion wedges, cut through the root so they hold together, turn sweet and jammy instead of scattering and burning. When everything is roughly the same size, everything finishes together.
Roasting, not steaming
The one way to spoil this dinner is a crowded pan. Piled-up vegetables steam in their own juices and come out soft and pale instead of caramelized, so use the biggest rimmed sheet pan you own — a half-sheet pan is ideal — and spread everything into a single layer with a little breathing room, splitting the batch across two pans if you need to. High heat matters too: 425°F (220°C) is what gives you the browned sausage, the blistered pepper skins and those crisp potato edges that make people pick at the pan before dinner is even served.
Ingredients
- 1 1/2 lb Italian sausage links, sweet or hot (680 g)
- 3 bell peppers, mixed colors, seeded and cut into 1/2-inch strips (about 450 g)
- 1 large red onion, cut into wedges through the root (about 200 g)
- 1 lb baby potatoes, halved (450 g)
- 3 tablespoons olive oil (45 ml), divided
- 3 garlic cloves, minced (about 9 g)
- 1 teaspoon Italian seasoning (2 g)
- 1 teaspoon kosher salt (6 g)
- 1/2 teaspoon black pepper (1.5 g)
- 1/2 teaspoon smoked paprika (1.5 g)
- Pinch of red pepper flakes (optional)
- Chopped fresh parsley, to serve
- Toasted hoagie rolls and provolone, for sandwiches (optional)

Step-by-step instructions
- Heat the oven. Preheat the oven to 425°F (220°C). Line a large rimmed sheet pan with parchment paper or foil for the easiest cleanup, or leave it bare and lightly oiled if you want maximum browning on the potatoes.
- Start the potatoes. Toss the potato pieces with 1 tablespoon of the olive oil, half the salt and a few grinds of pepper, and spread them on the pan cut-side down. Roast for 10 minutes while you prepare everything else — this head start is what guarantees tender potatoes later.
- Season the peppers and onions. In a large bowl, toss the pepper strips and onion wedges with the remaining 2 tablespoons of olive oil, the garlic, Italian seasoning, paprika, red pepper flakes if using, and the rest of the salt and pepper, until everything is glossy and evenly coated.
- Load the pan. Take the pan out of the oven and push the potatoes to one side. Add the peppers and onions in an even layer and nestle the sausage links among the vegetables, turning each sausage once in the oily juices so it browns evenly.
- Roast, turning once. Return the pan to the oven and roast for 25 to 30 minutes, turning the sausages and stirring the vegetables halfway through, until the sausages are browned and cooked through to 160°F (71°C), the peppers are soft with charred edges, and the potatoes are crisp outside and fluffy inside.
- Rest and serve. Rest the pan for 5 minutes — the sausages reabsorb their juices and the vegetables settle into them. Scatter with parsley and serve straight from the pan, in toasted rolls, or over polenta, rice or pasta.

Storage & reheating
Leftovers keep for up to 4 days in an airtight container in the refrigerator. Reheat on a sheet pan in a 375°F (190°C) oven for about 10 minutes, or in a skillet over medium heat, to bring back the caramelized edges; the microwave works but softens everything. Cooked sausage and vegetables freeze for up to 2 months, though the potatoes will be a little softer after thawing — undercook them slightly if you know the batch is headed for the freezer.
