These oven-baked bratwursts paired with roasted onions are a delightful and easy meal that elevates any dinner occasion. The combination of caramelized onions and savory sausages cooked to perfection makes this dish a family favorite.
Begin by preheating your oven to 425°F and adjusting the rack to the top position.
In a large bowl or directly in a cast iron skillet, combine the onion wedges with the brown sugar, olive oil, salt, pepper, and vinegar. Toss until the onions are thoroughly coated.
Spread the onion mixture in a single layer in the skillet. Place the bratwursts on top of the onions.
Transfer the skillet to the preheated oven. Roast for 15 minutes, then stir the onions and flip the sausages. Continue roasting for another 15 to 25 minutes, until the onions are caramelized and the sausages reach an internal temperature of 165°F.
