Method

Cooking Instructions

  1. 1

    Prepare the Onions

    Thinly slice the yellow onions. In a large pot, heat the butter and olive oil over medium heat until melted.

  2. 2

    Cook the Onions

    Add the sliced onions to the pot and stir to coat with the butter and oil. Cook the onions, stirring occasionally, for about 30-40 minutes until they are deep golden brown and caramelized.

  3. 3

    Add Garlic and Deglaze

    Minced the garlic and add it to the pot. Cook for another 2 minutes. Then pour in the white wine, scraping up any browned bits from the bottom of the pot, and let it simmer for 5 minutes.

  4. 4

    Add Broth and Seasonings

    Pour in the beef broth, add the thyme, bay leaf, salt, and pepper. Bring the soup to a boil, then reduce the heat to low and let it simmer for 20-30 minutes.

  5. 5

    Prepare the Baguette

    While the soup simmers, preheat the oven to 350°F (175°C). Slice the French baguette into thick slices and place them on a baking sheet. Toast in the oven for about 10 minutes until golden.

  6. 6

    Serve the Soup

    Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls, place a slice of toasted baguette on top, and sprinkle generously with Gruyère cheese. Place the bowls under the broiler until the cheese is bubbly and golden, about 3-5 minutes.
