  • 1 cup shredded Gruyere cheese
  1. Peel and cut onions in half and then finely slice the halves lengthwise.

  7. Ladle the soup in four oven safe bowls, leaving space on top for slice of bread. Place the bread slice on top with broiled side down and top with cheese. Place soup bowls on a baking sheet and broil it for a minute or until cheese is melted. Serve immediately.
