Ingredients
Scale
Onions and Seasoning
- 4 large yellow onions, peeled and sliced into ¼-inch rounds
- Olive oil, for drizzling
- ½ teaspoon fresh thyme, chopped
- Salt and pepper, to taste
Cream Sauce
- 1 cup heavy cream
- 2 teaspoons Dijon mustard
- ½ cup Asiago cheese, grated (divided into two ¼ cup portions)
Instructions
- Roast the Onions: Preheat your oven to 450°F (230°C). Lightly grease a baking dish. Arrange the sliced onions in a single layer at the bottom of the dish. Drizzle with olive oil and sprinkle with chopped thyme, salt, and pepper. Roast uncovered for 20 minutes until the onions begin to soften and caramelize.
- Prepare the Cream Sauce: While the onions roast, pour the heavy cream into a small saucepan and heat over medium heat until it starts to simmer. Stir in the Dijon mustard and half of the grated Asiago cheese. Allow the cheese to melt completely, stirring frequently, to create a smooth, creamy sauce.
- Assemble and Bake: Remove the onions from the oven and pour the warm cream sauce evenly over them. Sprinkle the remaining Asiago cheese on top. Cover the baking dish with foil and return it to the oven. Bake for an additional 20 minutes until the onions are tender, the cheese melts thoroughly, and the sauce bubbles around the edges.
Notes
- For a stronger herb flavor, add a sprinkle of fresh thyme after baking.
- Substitute Asiago cheese with Parmesan for a different but equally delicious flavor.
- To make this dish vegetarian, ensure the cheese used is free from animal rennet.
- Use a sharp knife to slice onions evenly for uniform cooking.
- Allow the dish to rest for five minutes after baking to thicken the sauce slightly before serving.
