French Onion Soup is a savory, comforting dish made by simmering caramelized onions in a rich beef stock and white wine broth. The soup is topped with a crusty baguette slice and melted Gruyere cheese, creating a delightfully gooey and satisfying texture. The slow-cooked onions impart a deep, sweet, and slightly sulfurous flavor to this classic soup.

French Onion Soup, a simmered dish featuring caramelized onions, savory beef stock, and melted Gruyere cheese, pairs well with a full-bodied white wine like Malvasia. The wine's rich texture and subtle sweetness complement the soup's deep, complex flavors, while its acidity cuts through the richness of the cheese. Alternatively, a light-bodied, fruity red like Aglianico can also work, as its bright acidity and subtle tannins balance the soup's richness.
