Method

Soup Preparation

  1. 1

    Sauté 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 a deep golden brown, about 20-25 minutes.

  2. 2

    Add Garlic

    Minced the garlic and add it to the pot. Cook for an additional 2 minutes until fragrant.

  3. 3

    Deglaze the Pot

    Pour in the dry white wine, scraping the bottom of the pot to release any browned bits. Allow the wine to simmer for about 5 minutes until it reduces slightly.

  4. 4

    Add Broth and Seasonings

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

  5. 5

    Taste and Adjust Seasoning

    Taste the soup and adjust the seasoning with more salt and pepper if needed. Remove the bay leaf before serving.

Serving

  1. 6

    Prepare the Baguette

    While the soup is simmering, slice the baguette into thick slices and toast them until golden brown.

  2. 7

    Assemble the Soup

    Ladle the hot soup into oven-safe bowls, top each bowl with a slice of toasted baguette, and generously sprinkle with Gruyère cheese.

  3. 8

    Broil the Cheese

    Place the bowls under the broiler in the oven until the cheese is bubbly and golden brown, about 2-3 minutes. Keep a close eye to avoid burning.

  4. 9

    Serve Hot

    Remove the bowls from the oven and let cool slightly before serving. Enjoy your classic French onion soup hot!
