Method

Preparation

  1. 1

    Slice the Onions

    Peel and thinly slice the yellow onions. Aim for uniform thickness for even cooking.

  2. 2

    Prepare the Garlic

    Mince the garlic cloves and set aside.

  3. 3

    Prepare the Broth

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

Cooking the Soup

  1. 4

    Add Garlic and Broth

    Once the onions are caramelized, add the minced garlic and cook for an additional 2 minutes. Pour in the beef broth, add thyme, bay leaf, salt, and pepper. Bring to a simmer.

  2. 5

    Simmer the Soup

    Allow the soup to simmer uncovered for 20 minutes to let the flavors meld. Remove the bay leaf before serving.

Preparing the Toppings

  1. 6

    Toast the Baguette

    Preheat the oven to 400°F (200°C). Slice the baguette into 1-inch thick pieces and arrange them on a baking sheet. Toast in the oven for about 5-7 minutes until golden brown.

  2. 7

    Prepare Cheese Topping

    In a bowl, mix the Gruyere and Parmesan cheese together.

Final Assembly

  1. 8

    Combine Soup and Cheese

    Ladle the hot soup into oven-safe bowls. Top each bowl with 1-2 toasted baguette slices and sprinkle generously with the cheese mixture.

  2. 9

    Bake the Soup

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

  3. 10

    Serve

    Remove from the oven and let cool for a few minutes before serving. Enjoy your delicious baked onion soup!
