Soup Base

Method

Soup Preparation

  1. 1

    Sauté Onions

    In a large pot, heat 2 tablespoons of olive oil over medium heat. Add the sliced yellow onions and a pinch of salt. Cook, stirring frequently, until the onions are deeply caramelized, about 20-25 minutes.

  2. 2

    Add Garlic

    Once the onions are caramelized, add the minced garlic and cook for an additional 2-3 minutes until fragrant.

  3. 3

    Deglaze with Wine

    Pour in 1 cup of dry white wine and scrape the bottom of the pot to release any flavorful bits. Let it simmer for about 5 minutes.

  4. 4

    Add Stock and Herbs

    Stir in the veal stock, fresh thyme leaves, bay leaf, salt, and black pepper. Bring to a simmer and let it cook for 30 minutes to meld the flavors.

Crostini Preparation

  1. 5

    Prepare Baguette

    While the soup is simmering, preheat your oven to 400°F (200°C). Slice the baguette into 1/2 inch thick slices.

  2. 6

    Toast Crostini

    Arrange the baguette slices on a baking sheet, brush both sides with 2 tablespoons of olive oil, and bake for 8-10 minutes or until golden and crispy.

  3. 7

    Add Garlic Flavor

    Remove the crostini from the oven and while still warm, rub the halved garlic cloves over the top of each slice.

Final Assembly

  1. 8

    Serve the Soup

    Remove the bay leaf from the soup. Ladle the hot caramelized onion soup into bowls.

  2. 9

    Add Cheese

    Top each bowl with a generous amount of grated aged Swiss cheese.

  3. 10

    Garnish with Crostini

    Serve each bowl with a few pieces of toasted crostini on the side for dipping.
