French Onion Soup Recipe

Soup Preparation

1. 1

   Caramelize the Onions

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

2. 2

   Add Garlic and Deglaze

   Stir in the minced garlic and cook for an additional 2 minutes. Then, add the white wine to deglaze the pot, scraping up any browned bits from the bottom.

3. 3

   Simmer the Soup

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

4. 4

   Prepare the Crostini

   While the soup is simmering, preheat the oven to 400°F (200°C). Slice a baguette into 1/2-inch slices, brush with olive oil, and bake for 5-7 minutes until golden.

5. 5

   Assemble and Serve

   Ladle the soup into oven-safe bowls, top with grated Gruyère cheese, and broil until the cheese is melted and bubbly. Serve with the garlic crostini on the side.
