Ingredients & Their Importance

Each ingredient is carefully chosen to elevate the humble onion into a gourmet side dish:

• 4 large sweet onions, peeled and sliced: Sweet onions like Vidalia or Walla Walla are perfect for roasting because their natural sugars intensify and soften during cooking.
• 3 tablespoons extra virgin olive oil: Helps the onions roast evenly, adds a subtle fruity flavor, and prevents sticking.
• 1 cup heavy cream: Creates a rich, velvety sauce that envelops the roasted onions, adding indulgent texture and depth.
• ¼ cup white wine: Adds acidity to balance the cream and enhance the onions’ natural sweetness. It also adds subtle aromatic complexity.
• ¼ cup grated Parmesan cheese: Melts and forms a golden, nutty crust, adding texture and a savory flavor that contrasts beautifully with the sweetness of the onions.
• Salt and pepper, to taste: Enhances all flavors and ensures a perfectly balanced dish.

Step-by-Step Instructions

Step 1: Preheat the Oven and Prepare Onions

Preheat your oven to 375°F (190°C). Peel the onions and slice them into even rings, keeping the layers intact. Uniform slices ensure even roasting and maintain their beautiful structure. Arrange onions in a parchment-lined baking dish, drizzle with olive oil, and season generously with salt and pepper. This simple preparation lays the foundation for caramelization and flavor infusion.

Step 2: Roast the Onions

Roast the onions for 20–25 minutes until they start to soften and caramelize. Halfway through, gently toss or rotate them to ensure even browning. Proper roasting brings out natural sweetness while maintaining tender layers.

Step 3: Make the Cream Sauce

While the onions roast, prepare the cream sauce. In a small saucepan, combine heavy cream and white wine over medium heat. Simmer gently for 2–3 minutes until slightly thickened. Season with salt and pepper. The sauce should coat the onions beautifully and enhance their natural sweetness.

Step 4: Combine Onions and Cream

Pour the cream sauce evenly over the roasted onions, ensuring all layers are coated. Stir gently to blend flavors without breaking up the onion layers. This step transforms simple roasted onions into a luxurious, velvety side dish.

Step 5: Add Parmesan and Finish Roasting

Sprinkle Parmesan over the cream-coated onions and return the dish to the oven. Bake for 10–15 minutes until the cheese melts and forms a lightly golden crust. Watch closely to avoid over-browning. The result is a perfect balance of creamy, sweet, and savory flavors.
