Onions

Method

Onion Preparation

  1. 1

    Melt Butter and Oil

    Melt the butter and olive oil in a large skillet over medium heat.

  2. 2

    Add Onions

    Add the sliced yellow onions to the skillet and stir to coat them in the butter and oil mixture.

  3. 3

    Caramelize Onions

    Cook the onions slowly, stirring frequently, until they are caramelized and golden brown, about 30-40 minutes.

Broth Preparation

  1. 4

    Combine Ingredients

    Once the onions are caramelized, add the beef broth, dry white wine, thyme, bay leaf, salt, and black pepper to the skillet.

  2. 5

    Simmer Broth

    Bring the mixture to a simmer, then reduce the heat to low and let it cook for an additional 20 minutes to allow the flavors to meld.

Serving Preparation

  1. 6

    Preheat Oven

    Preheat your oven to 400°F (200°C).

  2. 7

    Prepare Bowls

    Ladle the soup into oven-safe bowls and top each bowl with slices of baguette.

  3. 8

    Add Cheese

    Sprinkle Gruyère cheese and Parmesan cheese generously over the baguette slices.

  4. 9

    Bake Soup

    Place the bowls on a baking sheet and bake for about 10-15 minutes, or until the cheese is melted and bubbly.

  5. 10

    Cool and Serve

    Remove from the oven and let cool slightly before serving.
