Method

Cooking Instructions

  1. 1

    Caramelize the Onions

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

  2. 2

    Add Wine and Broth

    Pour in the dry white wine and cook for an additional 5 minutes, scraping up any bits from the bottom of the pot. Then add the beef broth, fresh thyme, bay leaf, salt, and black pepper.

  3. 3

    Simmer the Soup

    Bring the soup to a boil, then reduce the heat and let it simmer for 30-40 minutes to allow the flavors to meld.

  4. 4

    Prepare the Croutons

    While the soup is simmering, prepare croutons. Cut bread into cubes, toss with olive oil, salt, and pepper, and bake at 375°F (190°C) for about 10-15 minutes until golden brown.

  5. 5

    Serve the Soup

    Preheat your oven to broil. Ladle the soup into oven-safe crocks, top each with croutons and a generous layer of Swiss cheese. Place under the broiler for 2-3 minutes until the cheese is melted and bubbly. Serve immediately.
