While it cooks, let the baguette slices toast either in the toaster or in the oven until golden brown. Sprinkle grated cheese on each slice of bread then grill in the oven until it melts and goes golden.  

5. To serve: 

Ladle the soup into heatproof bowls. Place the cheesy bread slices on top of the soup and, if desired, place the entire bowl in the oven for a few minutes to further grill the cheese.
