Method

Preparation

  1. 1

    Slice the Onions

    Thinly slice the yellow onions and set them aside.

  2. 2

    Prepare the Broth

    In a large pot, melt the butter over medium heat. Add the sliced onions and sauté them until they are caramelized, about 25-30 minutes.

Cooking the Soup

  1. 3

    Add Liquid Ingredients

    Once the onions are caramelized, add the dry white wine to deglaze the pot, scraping up any browned bits. Allow the wine to simmer for about 5 minutes.

  2. 4

    Combine the Broth

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

Preparing the Topping

  1. 5

    Toast the Baguette

    Preheat your oven to 400°F (200°C). Slice the baguette into 1-inch thick slices and place them on a baking sheet. Toast in the oven for about 5-7 minutes, or until golden brown.

  2. 6

    Prepare the Cheese

    Grate the Gruyere cheese and set it aside.

Final Assembly

  1. 7

    Assemble the Gratinée

    Remove the bay leaves from the soup. Ladle the onion soup into oven-safe bowls, top each with a few slices of toasted baguette, and sprinkle generously with grated Gruyere cheese.

  2. 8

    Broil the Cheese

    Place the bowls on a baking sheet and broil in the oven for about 3-5 minutes, or until the cheese is bubbly and golden brown. Watch closely to avoid burning.
