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
- Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius) and prepare a baking sheet with parchment paper for optimal non-stick cooking.
- Arrange thin, translucent onion slices evenly across the prepared baking sheet, ensuring minimal overlap.
- Generously drizzle extra virgin olive oil over the onion layers, then season with kosher salt and freshly ground black pepper to enhance natural flavors.
- Roast the onions in the preheated oven for 15 minutes until they begin to soften and develop subtle caramelization.
- 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.
- Simmer the cream mixture over medium heat, stirring continuously until it thickens and develops a velvety consistency, approximately 5-7 minutes.
- Remove the partially roasted onions from the oven and increase the temperature to 450 degrees Fahrenheit (230 degrees Celsius) for final browning.
- Carefully pour the enriched cream sauce over the roasted onions, ensuring even distribution.
- Generously sprinkle freshly grated Parmesan cheese across the surface for a rich, nutty flavor profile.
- Cover the baking sheet with aluminum foil and return to the oven for 20 minutes to allow flavors to meld.
- 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.
