Prep Time 15 minutes
Cook Time 1 hour 10 minutes

Ingredients

  • 4 large yellow onions thinly sliced
  • 4 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • 1 teaspoon sugar
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 4 cups beef broth
  • 2 cups chicken broth
  • 1/2 cup dry white wine optional
  • 2 tablespoons all-purpose flour
  • 1 baguette sliced
  • 2 cups grated Gruyère cheese

Instructions

Caramelize the Onions:

  • In a large pot, melt the butter with the olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook, stirring frequently, until the onions are caramelized and golden brown, about 30-40 minutes.

Deglaze the Pot:

  • Sprinkle the flour over the caramelized onions and stir to coat. Cook for another 2-3 minutes. If using, pour in the white wine to deglaze the pot, scraping up any browned bits from the bottom.

Simmer the Soup:

  • Add the beef and chicken broths to the pot. Bring the mixture to a boil, then reduce the heat and let it simmer for 30 minutes. Season with salt and pepper to taste.

Prepare the Bread and Cheese:

  • Preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven until golden brown. Remove from the oven and set aside.

Assemble and Serve:

  • Ladle the soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl, then sprinkle with grated Gruyère cheese. Place the bowls under the broiler until the cheese is melted and bubbly. Serve hot.
