Description
A creamy and flavorful dish made with roasted yellow onions and Asiago cheese.
Ingredients
Scale
- 2 pounds yellow onions (about 4 medium or 2 large), peeled and sliced into 1/4 inch to 1/2 inch slices
- Olive oil
- 1/2 teaspoon thyme, chopped
- Salt and pepper to taste
- 1 cup of heavy cream
- 2 teaspoons Dijon mustard
- 1/2 cup of Asiago cheese, grated
Instructions
- Begin by washing and peeling your yellow onions. Slice them into uniform rounds, anywhere between 1/4 inch to 1/2 inch thick. This ensures that they roast evenly and develop that delicious sweetness. Once sliced, lay the onion rounds in a greased baking dish, spreading them out into a single layer. Drizzle with a good amount of olive oil to help caramelize the onions and sprinkle with chopped thyme, salt, and pepper. This step is crucial as it will build the flavor profile right from the start. Pop the baking dish into your preheated oven for 20 minutes to initiate the roasting process.
- While the onions roast, take a small saucepan and pour in the heavy cream over medium heat. Keep stirring it frequently to prevent it from sticking or simmering too vigorously. As the cream heats up, add in the Dijon mustard and half of your grated Asiago cheese. Stir until the cheese is completely melted and you achieve a luscious, creamy consistency. This sauce not only coats the onions but adds a delightful tang from the mustard, enhancing the overall flavor.
- Once the onions are tender after their roasting time, carefully remove them from the oven. Pour the creamy sauce evenly over the roasted onions, ensuring each piece gets a generous amount. Reserve the remaining grated Asiago cheese for the final touch. Sprinkle it over the top of the creamy onions. To maintain moisture and encourage the cheese to melt perfectly, cover the dish with aluminum foil and return it to the oven for an additional 20 minutes. During this time, the flavors will meld beautifully, and you’ll see the sides bubbling away, indicating that your dish is ready.
Notes
Cooking time may vary based on the thickness of onion slices; adjust as necessary. If Asiago cheese is unavailable, Gruyère or Parmesan can serve as substitutes without losing richness.
