Ingredients

Method

Directions

  1. 1

    Prepare the Onions

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

  2. 2

    Add Garlic

    Stir in the minced garlic and cook for an additional 2-3 minutes until fragrant.

  3. 3

    Deglaze the Pot

    Pour in the white wine and scrape the bottom of the pot to deglaze. Let it simmer for about 5 minutes.

  4. 4

    Add Broth and Seasonings

    Add the beef broth, bay leaves, thyme, salt, and black pepper. Bring the soup to a boil, then reduce the heat and let it simmer for 30 minutes.

  5. 5

    Prepare the Bread

    While the soup is simmering, preheat your oven to 350°F (175°C). Place the sliced French bread on a baking sheet and toast in the oven until golden brown, about 10 minutes.

  6. 6

    Serve the Soup

    Ladle the hot soup into bowls, place a slice of toasted bread on top of each serving, and sprinkle generously with shredded Gruyère cheese. You may place the bowls under the broiler for a few minutes to melt the cheese if desired.
