A classic French Onion Soup recipe that is rich, savory, and comforting. Caramelized onions simmered in a flavorful broth, topped with toasted baguette slices and melted Gruyere cheese.

Ingredients

Units Scale

For the Soup:

  • 5 large onions, thinly sliced
  • 4 tablespoons butter
  • 2 tablespoons olive oil
  • 2 cloves garlic, minced
  • 6 cups beef broth
  • 1 cup dry white wine
  • 2 bay leaves
  • Salt and pepper to taste

For the Toasted Baguette and Cheese:

  • 1 French baguette, sliced
  • 1 cup Gruyere cheese, grated
  • Fresh thyme for garnish

Instructions

  1. Caramelize the Onions: In a large pot, melt butter and olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until deeply golden brown and caramelized, about 45 minutes to 1 hour.
  2. Simmer the Soup: Add garlic to the caramelized onions and cook for another minute. Pour in the beef broth, white wine, bay leaves, salt, and pepper. Bring to a simmer and cook for an additional 20-30 minutes.
  3. Prepare the Cheesy Toast: Preheat the broiler. Ladle the soup into oven-safe bowls, top each with a slice of toasted baguette and a generous amount of Gruyere cheese. Place the bowls under the broiler until the cheese is melted and bubbly.
  4. Serve: Garnish with fresh thyme and serve hot.

Notes

  • This soup is best served immediately to enjoy the gooey cheese and crispy baguette.
  • For a deeper flavor, you can add a splash of brandy or sherry when simmering the soup.
