    Cook stirring at regular intervals until the onions have caramelised and become sticky. This will take at least 30 minutes (see cook 's note).

    Return to the heat and continue to cook stirring until slightly thickened.

    Brush the melted butter on both sides of the French bread pieces.
  • 12
    Place on a baking tray and cook either in the oven, or under a medium heat grill, turning once until lightly browned.
  • 13
    To finish the dish:
  • 14
    Pour the hot soup equally between the two casseroles and arrange 3 croÛtes on top of each.
