Ingredients

  • 4 large onions thinly sliced
  • 2 tablespoons butter
  • 2 tablespoons olive oil

  • 2 cups water
  • 1/2 cup dry white wine

Instructions

  • In a large pot, melt the butter with the olive oil over medium heat.

  • Add beef broth, water and salt. Bring to a simmer and cook for an additional 20-30 minutes.
  • Once the soup is ready, preheat the oven to broil.
  • Place bread slices on a baking sheet and top each slice with grated Gruyère cheese.
  • Broil in the oven until the cheese is melted and bubbly.
  • Ladle the hot French Onion Soup into regular soup bowls.
  • Place a cheesy bread slice on top of each bowl.
  • Serve hot and enjoy
