Instructions:
Preheat Oven: Set your oven to 400°F (200°C).
Prepare the Onions: Toss the sliced onions with olive oil ensuring they are well coated. Spread them evenly on a baking sheet.
Roasting:Place the baking sheet in the oven and roast the onions for approximately 15 minutes. They should be tender and have a slight caramelized edge to them.
Adjust Oven Temperature: Increase the oven’s heat to 450º F (230º C) and take out the roasted onions.
Prepare the Cream Sauce: In a saucepan set over medium heat, mix together the heavy cream, white wine, unsalted butter, and garlic powder. Continuously stir the mixture until the butter has fully melted and you can see bubbles forming along the edges of the cream.
Combine and Bake:Drizzle the creamy sauce mixture over the roasted onions, ensuring they are well-coated. Generously sprinkle the grated parmesan cheese on top. Cover the baking sheet with foil and place it back in the oven. Bake for 20 minutes.
Final Touch: After 20 minutes, remove the foil and continue baking for another 5-10 minutes. The goal is to have the onions further caramelize and the cheese turn a beautiful golden hue.
Serve:Take out of the oven and serve hot. The combined flavors of the sweet roasted onions and the rich creamy sauce promise a mouthful of delight with every bite.
Enjoy!
This dish can be paired beautifully with grilled meats or even as a standalone vegetarian option. The creaminess of the sauce, combined with the sweetness of the onions, makes for a harmonious blend of flavors and textures that is sure to impress anyone you serve it to.
