Soup Base

Method

Prepare the Soup

  1. 1

    Cook the Onions

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

  2. 2

    Add Garlic and Broth

    Add the minced garlic and cook for an additional 2 minutes. Then, pour in the white wine, scraping the bottom of the pot to release any browned bits. Allow it to simmer for 5 minutes.

  3. 3

    Combine Ingredients

    Add in the beef broth, thyme, bay leaf, salt, and pepper. Bring the soup to a gentle boil and then reduce the heat to low. Let it simmer for 30 minutes.

  4. 4

    Prepare for Serving

    Remove the bay leaf from the soup. Adjust seasoning if necessary.

Assemble and Broil

  1. 5

    Toast the Bread

    Preheat your broiler. Place the sourdough bread slices on a baking sheet and toast them under the broiler until golden brown on both sides.

  2. 6

    Serve the Soup

    Ladle the hot soup into oven-safe bowls. Place a toasted slice of sourdough on top of each bowl, then generously sprinkle with shredded gruyere cheese.

  3. 7

    Melt the Cheese

    Place the bowls under the broiler for about 3-5 minutes, or until the cheese is bubbly and golden brown. Be careful not to burn.
