By

Ingredients

  • 4 medium red onions, peeled, quartered, and separated
  • Olive oil
  • Fresh thyme, leaves picked
  • A few garlic cloves, peeled and sliced
  • 1/2 cup of white wine
  • 4 tablespoons crème fraîche
  • 1.75 ounces gruyère, grated
  • 1.75 ounces parmesan, grated

Preparation

Step 1

Preheat the oven to 400ºF. Toss the onions in a bowl with the olive oil, thyme, and garlic. Season well, and pour into a baking dish (such as a 9″ × 13″ Pyrex). Pour in the wine, and cover tightly with aluminum foil. Bake 45 minutes, remove the foil, and bake 15 more minutes. Turn the oven down to 350ºF. Stir in the crème fraîche, sprinkle on the cheese, and return to the oven until it all looks browned and beautiful.
