Ingredients
Scale
Main Ingredients:
- 4 large yellow onions, peeled and sliced into 1/4-inch rounds
- 1 cup heavy cream
- 1/2 cup Asiago cheese, grated
Herbs and Seasonings:
- 1/2 teaspoon fresh thyme, chopped
- Salt, to taste
- Black pepper, to taste
Finishing Ingredient:
- Olive oil, for drizzling
- 2 teaspoons Dijon mustard
Instructions
- Preheat oven to 450F (230C) and prepare a baking dish by lightly greasing its surface.
- Arrange onion slices in a uniform, single layer across the bottom of the prepared dish.
- Drizzle olive oil over the onion slices and sprinkle chopped thyme, salt, and pepper for seasoning.
- Roast onions for 20 minutes until they transform into soft, golden-edged caramelized rounds.
- Meanwhile, warm heavy cream in a saucepan over medium heat until it reaches a gentle simmer.
- Incorporate Dijon mustard into the cream, stirring consistently to create a smooth base.
- Blend half of the grated Asiago cheese into the cream sauce, allowing it to melt completely and create a rich, velvety texture.
- Remove roasted onions from the oven and carefully pour the creamy Asiago mixture evenly across the surface.
- Sprinkle remaining Asiago cheese over the top to create a golden, melting layer.
- Cover the baking dish with aluminum foil and return to the oven for an additional 20 minutes.
- Verify doneness by ensuring onions are tender, cheese is fully melted, and sauce bubbles around the edges.
Notes
- Select sweet onions like Vidalia for a milder, more delicate flavor that caramelizes beautifully and reduces potential sharpness.
- Slice onions uniformly to ensure even cooking and consistent texture throughout the dish, using a sharp knife for clean, precise cuts.
- Adjust cream sauce thickness by adding more cheese or reducing cream slightly, creating a personalized consistency that suits individual preferences.
- Transform this side dish into a vegetarian main course by adding roasted garlic, fresh herbs like rosemary, or incorporating vegetable broth for extra depth.
