National Vichyssoise Day

Celebrated on 11/18/2026

Quick Fact

Despite its French-sounding name, vichyssoise was actually invented in New York City in 1917 by French chef Louis Diat. He created the cold leek and potato soup as a variation of his mother's hot potato-leek soup, naming it after the town of Vichy, France, near his childhood home.

Origins and Establishment of National Vichyssoise Day

National Vichyssoise Day is celebrated annually on November 19th. The holiday was established to honor the unique history and culinary delight of vichyssoise, a cold soup made from leeks, potatoes, cream, and chicken stock. The exact origins of the observance are unclear, but it is believed to have been created by food enthusiasts or a culinary organization to promote appreciation for this classic soup. The date may have been chosen to coincide with the late autumn season, when the soup's comforting yet refreshing qualities are especially welcome.

Evolution and Modern Commemoration

Over time, National Vichyssoise Day has grown from a niche observance into a widely recognized food holiday. Initially celebrated primarily in culinary circles, it now garners attention from food bloggers, chefs, and home cooks who share recipes and variations online. Modern celebrations often include cooking demonstrations, soup tastings, and social media campaigns using hashtags like #NationalVichyssoiseDay. The day serves as a reminder of the soup's rich history and its enduring appeal as a versatile dish that can be served hot or cold.
