French Onion Soup Recipe

Soup Preparation

1. 1

   Cook the Onions

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

2. 2

   Deglaze the Pot

   Add the dry white wine to the pot to deglaze it, scraping up any browned bits from the bottom. Let it simmer for about 5 minutes.

3. 3

   Add Broth and Seasonings

   Pour in the beef broth, and add the thyme, bay leaf, salt, and black pepper. Bring the mixture to a simmer.

4. 4

   Simmer the Soup

   Reduce the heat to low and let the soup simmer for at least 30 minutes to allow the flavors to meld.

5. 5

   Prepare the Croutons

   While the soup is simmering, preheat the oven to 400°F (200°C). Cut a baguette into slices, place them on a baking sheet, and toast in the oven for about 10 minutes until golden.

6. 6

   Assemble and Serve

   Ladle the soup into oven-safe bowls, top with toasted baguette slices, and generously sprinkle with grated Gruyère cheese. Broil for 2-3 minutes until the cheese is bubbly and golden.
