Ingredients

  • 3 tablespoon unsalted butter
  • 3 large sweet onions about 2 pounds peeled and thinly sliced
  • 2 teaspoons vegetable or canola oil
  • ¾ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • 1 cup white wine
  • 4 cups beef bone broth I used Kettle and Fire
  • 8 sprigs thyme
  • 2 bay leaves
  • 4 slices baguette sliced into 1/2" rounds
  • 1 garlic clove optional
  • 2 teaspoons sherry
  • 4 ounces gruyere cheese grated

Instructions

    Cup of Yum
  1. In a large dutch oven over medium heat, melt the butter and oil together. Add the sliced onions and cook for 15 minutes until softened, stirring occasionally. Stir in the salt and pepper. Place the lid askew on the pot and continue to cook for an additional 45-50 minutes, stirring occasionally until they onions are caramelized. Moderate the heat if the onions are browning too quickly.
  2. Add the wine and simmer until most of the liquid has evaporated, about 10-15 minutes. Tie the thyme with a kitchen string into a tight bundle. Add the thyme, bay leaves and broth. Simmer for 15 minutes.
  3. Meanwhile preheat the oven to 400°. Slice the baguette into rounds and place on a baking sheet. Bake the bread for about 4-5 minutes, then flip the slices and cook for an additional 3-4 minutes, until toasts are crisp and lightly browned. Lightly rub the garlic over one side of the toasts.
  4. Turn up the oven to broil.
  5. Remove the thyme and bay leaves and discard. Add half a teaspoon of sherry each to 4 ovenproof crocks or bowls. Ladle the soup into the bowls and place on a baking sheet. Rest 1-2 toasts on top of each bowl of soup, depending on how large they are (garlic side up) and sprinkle each with the gruyere.
  6. Broil for 2-5 minutes until the cheese is melty and the edges of the bread are crisp. Serve.
