Method

Soup Preparation

  1. 1

    Slice the Onions

    Thinly slice the onions and set aside.

  2. 2

    Cook the Onions

    In a large pot, melt the butter and olive oil over medium heat. Add the sliced onions and cook, stirring frequently, until they are caramelized and golden brown, about 30-40 minutes.

  3. 3

    Add Garlic

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

  4. 4

    Deglaze with Wine

    Pour in the dry white wine and scrape the bottom of the pot to deglaze. Allow the wine to cook down slightly, about 5 minutes.

  5. 5

    Add Broth and Herbs

    Add the beef broth, thyme, bay leaf, salt, and pepper. Bring the mixture to a simmer and cook for 20-30 minutes to let the flavors meld.

  6. 6

    Remove Bay Leaf

    After simmering, remove the bay leaf from the soup.

Cheese Toast Preparation

  1. 7

    Prepare Baguette

    Slice the baguette into 1-inch thick slices and arrange them on a baking sheet.

  2. 8

    Toast Baguette

    Broil the baguette slices in the oven for 2-3 minutes until golden brown on top.

  3. 9

    Add Cheese

    Remove the toasted baguette from the oven and sprinkle Gruyere and Parmesan cheese generously on top of each slice.

  4. 10

    Melt Cheese

    Return the baguette slices to the oven and broil for an additional 2-3 minutes until the cheese is melted and bubbly.

Serving

  1. 11

    Serve Soup

    Ladle the hot onion soup into bowls and place a few cheese-topped baguette slices on top of each bowl.

  2. 12

    Garnish

    Optional: Garnish with additional thyme leaves or a sprinkle of black pepper before serving.
