Servings: 4


  • 4 large yellow onions peeled and sliced into ½" slices
  • ½ tsp thyme chopped
  • salt & pepper to taste
  • 1 cup heavy cream
  • 2 tsp dijon mustard
  • ½ cup Asiago cheese grated


  • Place the slices of onion in a single layer on the bottom of a greased baking dish, drizzle with oil and season with thyme, salt and pepper before roasting in a preheated 450° oven for 20 minutes.
  • Meanwhile, heat the heavy cream in a small saucepan until it starts to simmer, mix in the mustard and half of the cheese, let the cheese melt pour it over the onions before sprinkling on the remaining cheese.
