Ingredients

  • 4 large onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon sugar
  • 8 cups beef stock (or a combination of beef and chicken stock)
  • 1/2 cup dry white wine (optional)
  • 1 bay leaf
  • 1 teaspoon fresh thyme or 1/2 teaspoon dried thyme
  • 1 French baguette, sliced
  • 2 cups grated Gruyère cheese
  • Freshly ground black pepper to taste

Instructions

  1. Caramelize the Onions: In a large pot, melt the butter and olive oil over medium heat. Add the sliced onions, salt, and sugar. Cook for about 30-40 minutes, stirring frequently, until the onions are a deep golden brown.
  2. Add Stock and Season: Pour in the beef stock and white wine (if using). Add the bay leaf and thyme. Bring to a boil, then reduce heat and simmer for 30 minutes. Season with black pepper.
  3. Prepare Bread: While the soup is simmering, preheat the broiler. Toast the baguette slices until golden brown on both sides.
  4. Serve: Ladle the hot soup into oven-safe bowls, place a slice of toasted baguette on top of each bowl, and sprinkle with grated Gruyère cheese. Broil until the cheese is bubbly and golden.
  5. Enjoy: Let the soup cool slightly before serving, ensuring a warm and melty cheese topping awaits.
