Ingredients

Method

Directions

  1. 1

    Caramelize the Onions

    In a large pot, melt the butter over medium heat. Add the sweet onions, shallots, and leeks. Cook, stirring frequently, until the onions are caramelized and golden brown, about 25-30 minutes.

  2. 2

    Add Garlic and Deglaze

    Stir in the minced garlic and cook for an additional 2 minutes. Pour in the white wine to deglaze the pot, scraping up any browned bits from the bottom. Allow the wine to reduce for about 5 minutes.

  3. 3

    Simmer the Soup

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

  4. 4

    Prepare for Baking

    Preheat your oven to 350°F (175°C). Remove the bay leaves from the soup. Ladle the soup into oven-safe bowls and top each with a slice of baguette.

  5. 5

    Add Cheese and Bake

    Sprinkle the grated Fontina and Gruyere cheese generously over the baguette slices. Place the bowls on a baking sheet and bake in the preheated oven for 15-20 minutes, or until the cheese is bubbling and golden.

  6. 6

    Serve

    Carefully remove the bowls from the oven and let cool slightly before serving. Enjoy your delicious French Onion Soup!
