  • 3 tablespoons butter
  • 1 small yellow onion , halved lengthwise, then thinly sliced
  • 1 clove garlic , chopped
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon kosher salt
  • 1/8 teaspoon freshly ground black pepper
  • 1/4 cup red wine
  • 1 tablespoon all-purpose flour
  • 2 cups chicken broth
  • 1 thick slice French bread
  • 1/4 cup shredded Gruyere cheese


  • Melt the butter in a 2-quart saucepan over medium heat. Add the onions, garlic, thyme, salt and pepper and cook until the onions are very soft and caramelized, about 25 minutes.
  • Add the wine, bring to a boil, reduce the heat and simmer until the wine has evaporated, about 5 minutes.
  • Sprinkle the flour over the onions and stir. Reduce the heat to medium-low and cook for 10 minutes, stirring occasionally so that the flour doesn't burn.
  • Stir in the chicken broth and bring the soup back to a simmer, cook for 10 minutes.
  • Taste and add additional salt, if necessary.
  • Heat the broiler. Place the slice of French bread on a baking sheet. Sprinkle the Gruyere cheese over the top and broil until bubbly and golden brown, 3-4 minutes.
  • Place the bread in a soup bowl and pour the soup over the top.
