Ome of the first soups that I ever learned how to make was French onion.
Although it contains few ingredients, French onion is one of the most complex and satisfying soups out there.
The combination of a rich onion soup paired with crunchy bread and melted, gooey cheese creates a dish that is better than the sum of its parts.
The ratio of soup to cheese to bread is a very important concept in a good French onion.
The earthenware crocks that French onion soup is commonly served in helps keep this ratio in check.
