Ingredients Method Notes

Ingredients
  

Main Ingredients
  • 2 pounds yellow onions, peeled and sliced into 1/4 inch to 1/2 inch slices About 4 medium or 2 large onions.
  • 1 cup heavy cream
  • 1/2 cup Asiago cheese, grated
  • 1/2 teaspoon thyme, chopped
  • 2 teaspoons dijon mustard
  • Olive oil For drizzling.
  • Salt and pepper to taste

Method
 

Preparation
  1. Preheat your oven to 450°F (230°C). Grease a baking dish to prevent sticking.
  2. Place the sliced onions in a single layer at the bottom of the dish. Drizzle with olive oil and season with thyme, salt, and pepper.
Roasting
  1. Roast the onions in the preheated oven for 20 minutes, until they begin to soften and develop a lovely golden color.
  2. While the onions roast, heat the heavy cream in a small saucepan over medium heat until it starts to simmer.
  3. Stir in the dijon mustard and half of the grated Asiago cheese, allowing it to melt completely.
Finishing
  1. Once the onions are ready, pour the creamy cheese mixture over them. Sprinkle the remaining Asiago cheese on top.
  2. Cover the dish with foil and bake for another 20 minutes. It’s done when the onions are tender, the cheese is melted, and the mixture is bubbling around the edges.

Notes

To store leftovers, let them cool completely, then transfer to an airtight container. They'll keep in the fridge for up to 3 days or can be frozen for up to 2 months. Reheat before serving.
