French onion soup is a classic dish originating from France, celebrated for its rich and savory flavor. Traditionally, it is made with caramelized onions simmered in a beef or chicken broth, often infused with wine or brandy, which adds depth to its taste. The soup is typically topped with a slice of toasted baguette and a generous layer of melted Gruyère cheese, then broiled until bubbly and golden. This comforting, aromatic soup is a favorite in French cuisine and is enjoyed worldwide, especially as a warm and hearty meal during the colder months.
