Caramelized Onion Soup Recipe

Soup Preparation

1. 1

   Caramelize Onions

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

2. 2

   Add Broth and Seasonings

   Stir in minced garlic, thyme, bay leaf, salt, and pepper. Pour in the beef broth and bring to a simmer. Cook for an additional 20 minutes to allow flavors to meld.

3. 3

   Prepare Croutons

   While the soup is simmering, preheat the oven to 375°F (190°C). Toast the slices of French bread in the oven for about 5-7 minutes until lightly golden. Remove from the oven, sprinkle with Parmesan cheese, and return to the oven until the cheese is melted and bubbly.

4. 4

   Serve

   Ladle the soup into bowls, top with Parmesan croutons, and serve hot.
