Ingredients
Scale
- 3 sweet onions, thinly sliced
- 1 cup (240 ml/8 fl oz) heavy whipping cream
- ½ cup (50 g/1.75 oz) parmesan cheese, grated
- 4 tbsps (56 g/2 oz) butter
- 3 tbsps (45 ml/1.5 fl oz) olive oil
- ¼ cup (60 ml/2 fl oz) white cooking wine
- 1 tsp garlic powder
- ¼ tsp cayenne pepper
- salt and pepper to taste
Instructions
- Preparation: Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper for easy cooking and clean-up.
- Onion Layering: Spread thin onion slices across the sheet, ensuring minimal overlapping to promote even roasting and caramelization.
- Initial Seasoning: Drizzle extra virgin olive oil over onions, then season with kosher salt and black pepper to amplify natural flavors and create a robust foundation.
- First Roasting Phase: Place onions in the oven for 15 minutes, allowing them to soften and develop delicate caramelized edges.
- Cream Sauce Creation: Simultaneously, combine white cooking wine, unsalted butter, garlic powder, heavy whipping cream, and cayenne pepper in a saucepan over medium heat.
- Sauce Development: Whisk the cream mixture continuously until it transforms into a smooth, thickened sauce with a luxurious consistency, approximately 5-7 minutes.
- Temperature Adjustment: Increase oven temperature to 450°F (230°C) and remove partially roasted onions for the next stage of preparation.
- Cream Integration: Pour the velvety cream sauce evenly over the roasted onions, ensuring complete coverage and flavor distribution.
- Cheese Topping: Generously sprinkle freshly grated Parmesan cheese across the surface, creating a rich and nutty flavor layer.
- Final Baking: Cover the baking sheet with aluminum foil and return to the oven for 20 minutes, allowing flavors to meld and intensify, then uncover and bake an additional 10 minutes until the top achieves a golden, crispy finish.
Notes
- Slice Evenly: Use a sharp knife or mandoline to create uniform, thin onion slices for consistent cooking and elegant presentation.
- Oil Distribution: Ensure every onion slice is lightly coated with olive oil to prevent burning and promote even caramelization.
- Cream Sauce Technique: Stir constantly while simmering to prevent sauce separation and achieve a smooth, velvety texture.
- Cheese Coating: Grate Parmesan fresh for maximum flavor intensity and melt-ability, avoiding pre-packaged grated cheese.
