Roasted sausages and potatoes with rosemary are an easy, crowd-pleasing Italian sheet pan meal. This high protein mediterranean dinner is family-friendly and requires minimal preparation.
Preheat the oven to 425°F and position a rack in the top third for best browning.
Cut the Yukon Gold potatoes into 1-inch chunks and slice the red onion into thick wedges.
On a large sheet pan, combine potatoes, onion, whole garlic cloves, and drizzle with olive oil, tossing to coat evenly; season with salt, pepper, and rosemary sprigs.
Scatter sausage links (leave whole) evenly among the vegetables; avoid overcrowding to promote crispness.
Roast for 35–40 minutes, flipping sausages and stirring potatoes halfway through, until the sausages are golden and fully cooked and potatoes are brown and tender.
Rest 5 minutes out of the oven, then slice sausage if desired and serve hot.
