French onion soup is a rich and flavorful soup that is made with caramelized onions, beef broth, and melted cheese. It starts with thinly slicing onions and sautéing them in butter until they are golden brown and caramelized. The onions are then simmered in beef broth until the flavors meld together. The soup is served in individual bowls, topped with toasted bread and melted cheese, and broiled until the cheese is bubbly and golden. It's a classic and delicious soup that is perfect for a cozy dinner.
