Ive often seen it on cooking shows with a large crouton on top of the soup with cheese on the crouton. French onion soup is also often served in individual crocks (crocks meaning a small pot not the footwear).
Of course. That is the original French Onion Soup. It is a pain to make. I have only ever eaten it at Simchos when they use puff pastry dough as the top instead of cheese.
