A rich soup of slowly browned onions in beef stock, topped with toasted bread and melted cheese and browned under the grill.

Serves 4 1 h 30 min

Ingredients

  • 1 kg onions, thinly sliced
  • 50 g butter
  • 1 tablespoon flour
  • 150 ml dry white wine

  • 8 slices of baguette
  • 150 g Gruyère or Comté cheese, grated

  1. Melt the butter in a large pot and cook the onions over low heat for about 40 minutes, stirring often, until soft and deep golden brown.
  2. Sprinkle over the flour and stir for a minute.
  3. Pour in the wine, let it bubble for a minute, then add the stock. Simmer for 20 minutes and season.
  4. Toast the baguette slices.
  5. Ladle the soup into ovenproof bowls, float two slices of toast in each and cover with cheese.
  6. Grill until the cheese is melted and golden. Take care: the bowls will be very hot.
