French Onion Soup Recipe

Prepare the Onions

In a large pot, melt 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 Garlic and Wine

Once the onions are caramelized, add the minced garlic and cook for an additional 2 minutes. Then pour in the white wine, scraping the bottom of the pot to deglaze.

Add Broth and Seasonings

Add the beef broth, thyme, bay leaf, salt, and black pepper. Bring to a boil, then reduce the heat and let it simmer for 30 minutes.

Prepare the Baguette

While the soup is simmering, slice the baguette into 1-inch thick slices and toast them until golden brown.

Serve the Soup

Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls, top each with a toasted baguette slice, and sprinkle with Gruyère cheese. Place under the broiler until the cheese is bubbly and golden.
