Ingredients

Scale

Main Ingredients:

  • 3 Sweet onions, thinly sliced
  • 1 cup (240 milliliters) Heavy whipping cream
  • ½ cup (50 grams) Parmesan cheese, grated

Fats and Oils:

  • 4 tablespoons (56 grams) Butter
  • 3 tablespoons (45 milliliters) Olive oil

Seasonings and Liquids:

  • ¼ cup (60 milliliters) White cooking wine
  • 1 teaspoon Garlic powder
  • ¼ teaspoon Cayenne pepper
  • Salt and pepper to taste

Instructions

  1. Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius) and prepare a baking sheet with parchment paper for optimal non-stick cooking.
  2. Arrange thin, translucent onion slices evenly across the prepared baking sheet, ensuring minimal overlap.
  3. Generously drizzle extra virgin olive oil over the onion layers, then season with kosher salt and freshly ground black pepper to enhance natural flavors.
  4. Roast the onions in the preheated oven for 15 minutes until they begin to soften and develop subtle caramelization.
  5. Meanwhile, craft the luxurious cream sauce by combining white cooking wine, unsalted butter, garlic powder, heavy whipping cream, and a pinch of cayenne pepper in a medium saucepan.
  6. Simmer the cream mixture over medium heat, stirring continuously until it thickens and develops a velvety consistency, approximately 5-7 minutes.
  7. Remove the partially roasted onions from the oven and increase the temperature to 450 degrees Fahrenheit (230 degrees Celsius) for final browning.
  8. Carefully pour the enriched cream sauce over the roasted onions, ensuring even distribution.
  9. Generously sprinkle freshly grated Parmesan cheese across the surface for a rich, nutty flavor profile.
  10. Cover the baking sheet with aluminum foil and return to the oven for 20 minutes to allow flavors to meld.
  11. Uncover and continue baking for an additional 10 minutes until the top turns golden brown and the edges become crispy and bubbly.

Notes

  • Achieve perfectly caramelized onions by slicing them thinly and evenly for consistent roasting.
  • Create a rich, velvety sauce by simmering cream mixture until it thickens, enhancing the overall flavor profile.
  • Elevate the dish’s taste with a strategic two-stage baking process: first roasting, then creaming and browning.
  • Use high-quality Parmesan cheese for a nutty, robust finish that complements the sweet roasted onions.
  • Control heat levels carefully to prevent burning while ensuring golden, bubbly texture on top.
  • Select fresh, firm onions for the best taste and texture in this luxurious side dish.
