French Onion Soup Recipe

Cooking Instructions

1. 1

   Prepare the Onions

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

2. 2

   Add the Liquid Ingredients

   Once the onions are caramelized, add the dry white wine to deglaze the pot, scraping any browned bits from the bottom. Allow the wine to reduce by half, about 5 minutes.

3. 3

   Simmer the Soup

   Add the beef broth, thyme, bay leaf, salt, and black pepper to the pot. Bring the mixture to a gentle simmer and cook for an additional 30 minutes.

4. 4

   Prepare the Crostini

   While the soup is simmering, preheat the oven to 400°F (200°C). Slice the baguette into 1-inch thick slices. Place on a baking sheet and toast in the oven for about 5-7 minutes or until golden brown.

5. 5

   Assemble the Soup

   Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls, top each with a slice of toasted baguette, and sprinkle with Swiss and Parmesan cheese.

6. 6

   Broil and Serve

   Place the bowls under the broiler for 2-3 minutes, or until the cheese is bubbly and golden. Serve hot.
