French Onion Soup Recipe

Soup Preparation

1. 1

   Caramelize 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 (about 30-40 minutes). Add minced garlic during the last 5 minutes of cooking.

2. 2

   Add Liquids

   Pour in the white wine, scraping the bottom of the pot to deglaze. Allow it to simmer for 5 minutes, then add the beef broth, thyme, bay leaves, salt, and black pepper.

3. 3

   Simmer the Soup

   Bring the soup to a boil, then reduce the heat and let it simmer for 30 minutes. Remove bay leaves before serving.

4. 4

   Prepare the Croutons

   While the soup is simmering, prepare garlic croutons. Cut bread into cubes, toss with olive oil, minced garlic, salt, and bake at 375°F (190°C) until golden brown.

5. 5

   Serve the Soup

   Ladle the soup into bowls, top with croutons, and sprinkle generously with gruyere and provolone cheese. Place under the broiler until the cheese is melted and bubbly.
