French onion soup is a classic soup that is perfect for a cold day. It is made with onions, beef broth, and bread. The onions are caramelized until they are sweet and tender. The beef broth is added to the onions and simmered until the flavors are blended. The soup is then topped with a slice of bread and melted cheese. This soup is easy to make and can be made in under an hour. It is a great way to warm up on a cold day.
