Soup Base

Method

Preparing the Soup Base

  1. 1

    Caramelizing the Onions

    In a large pot, melt the butter and olive oil over medium heat. Add the sliced yellow onions and a pinch of salt. Cook, stirring frequently, until the onions are deeply caramelized and golden brown, about 30-40 minutes.

  2. 2

    Adding Garlic and Broth

    Once the onions are caramelized, add the minced garlic and cook for another 1-2 minutes until fragrant. Pour in the white wine to deglaze the pot, scraping any browned bits from the bottom. Let it simmer for 5 minutes.

  3. 3

    Simmering the Soup

    Add the beef broth, thyme leaves, bay leaf, salt, and black pepper. Bring the mixture to a boil, then reduce the heat and let it simmer for 20-25 minutes.

Serving the Soup

  1. 4

    Preparing the Bread

    While the soup is simmering, preheat your oven to 400°F (200°C). Place the sliced baguette on a baking sheet and toast in the oven for about 5-7 minutes until golden and crispy.

  2. 5

    Assembling the Soup

    Remove the bay leaf from the soup and ladle the soup into oven-safe bowls. Top each bowl with a slice of toasted baguette and sprinkle generously with Gruyère and Parmesan cheese.

  3. 6

    Melting the Cheese

    Place the bowls under the broiler in the oven for 3-5 minutes, or until the cheese is bubbly and golden brown. Keep a close watch to prevent burning.

  4. 7

    Serving

    Carefully remove the bowls from the oven and let them cool slightly before serving. Enjoy your classic French onion soup!
