Ingredients

  • 50 g butter
  • 1 tbs olive oil
  • 1 kg onion
  • 1 tsp sugar
  • 4 clove garlic
  • 2 tbs all-purpose flour
  • 250 ml dry white wine
  • 1 L beef broth
  • 4 slice crusty bread
  • 140 g Gruyère cheese

Steps

  1. Melt butter and olive oil in a large heavy-based pot over medium heat. Add sliced onions and cook, covered, for 10 minutes until softened.
  2. Uncover, sprinkle in sugar, and continue to cook for 20-30 minutes, stirring frequently, until onions are deeply caramelized and golden brown. Add minced garlic during the last few minutes of cooking.
  3. Sprinkle flour over the caramelized onions and stir well. Gradually whisk in the dry white wine, then slowly add the hot beef broth.
  4. Bring the soup to a simmer, then cover and cook for 15-20 minutes to allow flavors to meld.
  5. Preheat your oven broiler. Ladle the hot soup into oven-safe bowls.
  6. Place one or two slices of toasted bread on top of each bowl of soup, then generously cover with shredded Gruyère cheese.
  7. Broil for 2-4 minutes, or until the cheese is melted and bubbly and golden brown. Serve immediately.
