  • 3 sweet onions, peeled and thinly sliced
  • 1 cup heavy cream
  • 1/4 cup white wine
  • 1/2 cup parmesan cheese, grated
  • 4 tablespoons unsalted butter
  • 3 tablespoons extra-virgin olive oil
  • 1 teaspoon garlic powder
  • 1/4 teaspoon cayenne, optional
  • Kosher salt and freshly ground pepper, to taste


  1. Preheat and Prepare:
    • Preheat your oven to 400°F (200°C). Grease a baking dish with a little olive oil or cooking spray.
  2. Roast the Onions:
    • Place the thinly sliced onions in the prepared baking dish. Drizzle with olive oil and season with salt, pepper, and garlic powder. Toss to coat the onions evenly.
    • Roast in the preheated oven for 25-30 minutes, or until the onions are tender and golden brown, stirring occasionally to ensure even cooking.
  3. Prepare the Cream Sauce:
    • In a saucepan, heat the butter over medium heat until melted. Add the white wine and simmer for 2-3 minutes to cook off the alcohol.
    • Pour in the heavy cream and bring to a gentle simmer. Cook for another 5-7 minutes, stirring occasionally, until the sauce has thickened slightly.
  4. Add Parmesan Cheese:
    • Stir in the grated parmesan cheese until melted and smooth. Adjust the seasoning with salt, pepper, and cayenne pepper if using, to taste.
  5. Combine Onions and Cream Sauce:
    • Once the onions are roasted, remove them from the oven and transfer them to a serving dish.
    • Pour the creamy parmesan sauce over the roasted onions, ensuring they are well coated.
  6. Garnish and Serve:
    • Garnish the dish with a sprinkle of freshly grated parmesan cheese and chopped parsley, if desired.
    • Serve the Roasted Parmesan Creamed Onions hot as a luxurious side dish alongside your favorite entrees.

Cook’s Notes and Variations:

  • Caramelized Onions: For an even richer flavor, caramelize the onions on the stovetop before roasting them in the oven.
  • Herb Infusion: Add a touch of freshness by infusing the cream sauce with herbs such as thyme, rosemary, or parsley.
  • Breadcrumbs Topping: For added texture, sprinkle breadcrumbs mixed with grated parmesan cheese over the dish before serving.
