Always requested: Just 5 ingredients. Grandma swears by this one.

 Sheet pan sausage and peppers is one of those quietly brilliant dishes that shows up in Italian-American home kitchens, street fairs, and sandwich shops alike. At its core, it’s just good sausage, sweet bell peppers, and onions roasted together until everything is caramelized and deeply savory. Traditionally, you’d see this piled into a crusty roll, but here we’re keeping things low carb and streamlined—just five main ingredients and a tin foil–lined tray for easy cleanup. It’s the kind of recipe you pull out on a busy weeknight when you still want real flavor: minimal prep, one pan, and a dinner that tastes like it took much more effort than it did.

To keep this dish low carb, I like to serve the sausage and peppers over a bed of sautéed greens (spinach, kale, or Swiss chard) or simple roasted cauliflower. A crisp green salad with a tangy vinaigrette also works beautifully, cutting through the richness of the sausage. If you’re cooking for a mixed crowd, you can set out a bowl of cooked quinoa, farro, or even toasted hoagie rolls on the side so everyone can customize their own plate. A spoonful of pesto or a drizzle of good extra-virgin olive oil at the table adds a nice finishing touch without complicating the cooking process.

Low Carb 5-Ingredient Sheet Pan Sausage and Peppers

Servings: 4 servings

Ingredients

1 1/2 pounds Italian sausage links (about 4–5 links; mild or hot)

3 large bell peppers, mixed colors, sliced into 1/2-inch strips

1 large yellow onion, sliced into 1/2-inch wedges or strips

2 tablespoons olive oil

1 teaspoon kosher salt

1/2 teaspoon freshly ground black pepper

Directions

1. Preheat your oven to 400°F (200°C). Line a sheet pan or shallow tin foil tray completely with heavy-duty aluminum foil, folding the edges up to catch any juices and make cleanup easy.

2. Prepare the vegetables: Slice the bell peppers into 1/2-inch strips and the onion into 1/2-inch wedges or strips. Spread them evenly on the foil-lined tray.

3. Season the vegetables: Drizzle the peppers and onions with the olive oil, then sprinkle with the kosher salt and black pepper. Toss directly on the tray with your hands or tongs until everything is well coated, then spread into an even layer.

4. Add the sausage: Nestle the sausage links on top of the pepper and onion mixture, spacing them out so they roast rather than steam.

5. Roast: Place the tray in the preheated oven and roast for 20 minutes. After 20 minutes, carefully remove the tray, turn the sausages with tongs, and give the vegetables a quick stir to promote even browning.

6. Finish roasting: Return the tray to the oven and roast for another 15–20 minutes, or until the sausages are cooked through (an internal temperature of 160°F/71°C for pork) and the peppers and onions are tender with caramelized edges.

7. Rest and serve: Let the sausages rest on the tray for 5 minutes. Slice the sausages into thick pieces if you like, then toss them back with the peppers and onions so everything mingles. Taste a pepper and adjust seasoning with a bit more salt and pepper if needed, then serve hot.

Variations & Tips

You can take this basic pan of sausage and peppers in several directions without losing its low-carb simplicity. For a spicier version, use hot Italian sausage and add a pinch of red pepper flakes to the vegetables before roasting. If you prefer poultry, swap in chicken Italian sausage; just keep an eye on cooking time, as some chicken sausages cook a bit faster. Smoked sausage or kielbasa also works well and adds a different flavor profile. To incorporate more vegetables while staying low carb, add sliced zucchini or halved mushrooms to the tray—just cut them in similar sizes so they roast evenly. A splash of balsamic vinegar or a squeeze of lemon over the finished dish brightens the flavors without adding fuss. For meal prep, roast a double batch and store in the refrigerator for up to 4 days; it reheats nicely in a skillet with a little olive oil. Finally, if you miss the sandwich-shop experience but want to stay lower carb, serve the sausage and peppers in lettuce wraps or over a bed of riced cauliflower for that same satisfying combination of juicy sausage and sweet, roasted vegetables.
