The Recipe:

While there are countless variations of French onion soup, the basic recipe remains relatively unchanged. Here’s a simple yet delicious rendition to try at home:


  • 4 large onions, thinly sliced
  • 4 tablespoons butter
  • 2 cloves garlic, minced
  • 1 tablespoon all-purpose flour
  • 6 cups beef broth
  • 1 cup dry white wine
  • Salt and pepper to taste
  • Baguette slices
  • Gruyère cheese, grated


  1. In a large pot, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, until caramelized and golden brown, about 30-40 minutes.
  2. Add the minced garlic and cook for an additional 2-3 minutes.
  3. Sprinkle the flour over the onions and garlic, stirring constantly for 1-2 minutes to cook out the raw flour taste.
  4. Gradually pour in the beef broth and white wine, stirring to combine. Bring the soup to a simmer and let it cook for 20-30 minutes to allow the flavors to meld.
  5. Season the soup with salt and pepper to taste.
  6. Preheat the broiler. Ladle the soup into oven-safe bowls and top each with a slice of baguette and a generous amount of grated Gruyère cheese.
  7. Place the bowls under the broiler until the cheese is melted and bubbly, about 2-3 minutes.
  8. Serve hot and enjoy!

Tips for Success:

  • Be patient when caramelizing the onions; slow and steady cooking is key to achieving that deep, sweet flavor.
  • Use a good quality beef broth for the base of the soup, or make your own for an extra special touch.
  • Don’t skimp on the cheese! Gruyère is traditional for French onion soup, but you can also experiment with other varieties like Swiss or Mozzarella.
