🏛️ The History of French Onion Soup: From Humble Beginnings to Global Fame

Believe it or not, French Onion Soup wasn’t always the elegant dish we know today. Its origins trace back to ancient times when onions were a dietary staple because they were cheap, easy to grow, and lasted a long time.

🍽️ Origins in French Cuisine: A Peasant Dish Turned Gourmet Delight

In 18th-century France, onion soup was considered food for the poor. Onions were abundant and affordable, making the soup a practical meal during tough times. The transformation into a gourmet dish happened when chefs in Parisian restaurants started serving it with toasted bread and melted cheese on top, elevating its status.
