French Onion Soup Recipe

Instructions for French Onion Soup

1. 1

   Prepare the Onions

   Slice the yellow onions thinly. In a large pot, melt the butter and olive oil over medium heat. Add the onions and stir to coat them in the fat.

2. 2

   Caramelize the Onions

   Cook the onions, stirring frequently, for about 30-40 minutes until they are deeply caramelized and golden brown. Reduce heat if they start to burn.

3. 3

   Add Liquids and Seasonings

   Pour in the dry white wine and scrape the bottom of the pot to deglaze. Add the beef broth, thyme, bay leaf, salt, and pepper. Bring to a simmer.

4. 4

   Simmer the Soup

   Let the soup simmer for at least 30 minutes to meld the flavors. Adjust seasoning to taste.

5. 5

   Prepare the Croutons

   While the soup simmers, slice the French baguette into thick rounds. Toast the slices in the oven until golden brown.

6. 6

   Assemble the Soup

   Ladle the soup into oven-safe bowls. Place a toasted crouton on top of each bowl and sprinkle generously with Gruyère and Parmesan cheese.

7. 7

   Broil the Soup

   Place the bowls under the broiler for about 3-5 minutes until the cheese is melted and bubbly. Be careful not to burn.
