This Sheet Pan Sausage and Vegetables is an easy, flavor-packed dinner made with smoked sausage, bell peppers, zucchini, and red onion, all roasted together on one pan. Ready in about 40 minutes, it’s perfect for busy weeknights, meal prep, and minimal cleanup.
Preheat your oven to 400°F. Line a large sheet pan with parchment paper or foil.
Slice the sausage into ½-inch rounds. Chop the bell peppers, slice the zucchini, and cut the onion into wedges.
Spread the vegetables in a single layer on the sheet pan. Drizzle with olive oil and sprinkle with Italian seasoning, garlic powder, salt, and pepper. Toss everything right on the pan.
Add the sliced sausage, tucking it in between the vegetables.
Bake for 30–35 minutes, stirring halfway through, until everything is tender and slightly browned.
Optional: Sprinkle with Parmesan and parsley before serving.
