Transform humble onions into a gourmet side dish with this rich, savory recipe. Roasting brings out their natural sweetness, while a creamy Parmesan sauce adds luxurious texture and flavor. To make this dish, you’ll need sweet onions, heavy cream, white wine, Parmesan cheese, butter, olive oil, garlic powder, cayenne pepper, salt, and black pepper. Preheat the oven to 375°F and arrange the onion slices in a 9×13″ baking dish. Drizzle them with olive oil, and season with salt and pepper. Roast for 15 minutes until softened, then increase the oven temperature to 450°F. While the onions roast, melt butter in a saucepan over medium heat. Stir in the heavy cream, wine, garlic powder, and cayenne pepper, letting it gently simmer. Pour the sauce over the roasted onions and sprinkle generously with Parmesan cheese. Cover with foil and roast for 20 minutes, then uncover and roast for another 5–10 minutes until the onions are caramelized and the cheese turns golden brown. Serve hot and enjoy this sweet, savory, creamy, and unforgettable dish that pairs perfectly with roasted meats or stands out on its own as a luxurious side
