Soup Base

Toppings

Method

Preparing the Soup Base

  1. 1

    Sauté the Onions

    In a large pot, melt the butter over medium heat. Add the sliced red and yellow onions. Cook, stirring frequently, for about 15-20 minutes until the onions are caramelized and golden brown.

  2. 2

    Add Garlic and Wine

    Minced the garlic and add it to the pot with the caramelized onions. Stir in the red wine and cook for an additional 5 minutes, allowing the alcohol to evaporate.

  3. 3

    Add Broth and Seasonings

    Pour in the vegetable broth, then add thyme, bay leaf, salt, and black pepper. Bring the mixture to a boil, then reduce heat to low and let simmer for about 30 minutes.

Preparing the Toppings

  1. 4

    Prepare the Baguette

    While the soup is simmering, preheat the oven to 350°F (175°C). Slice the French baguette into thick slices and place them on a baking sheet.

  2. 5

    Toast the Baguette

    Toast the sliced baguette in the preheated oven for about 10 minutes or until golden brown and slightly crispy.

  3. 6

    Assemble the Soup

    Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls, place the toasted baguette slices on top, and generously sprinkle with Swiss cheese.

  4. 7

    Broil to Melt Cheese

    Place the assembled bowls under the broiler for 2-3 minutes or until the cheese is bubbly and golden.

Garnishing and Serving

  1. 8

    Garnish

    Finely chop the green onions and sprinkle them over the top of the melted cheese for added flavor and color.

  2. 9

    Serve

    Serve the French onion soup hot, ensuring each bowl has a portion of the toasted baguette and melted cheese.
