National Vichyssoise Day Date in the current year: November 18, 2024

Vichyssoise is made with chicken stock, cream, and pureed vegetables (leeks, onions, and potatoes). It is usually served cold, but can be eaten hot. The soup is named after the French town of Vichy.

The origins of vichyssoise are dabatable. Some believed it is an American invention, while others claim it was first made in France. However, almost everyone agrees that it was reinvented in the United States by Louis Diat, a French chef at the Ritz-Carlton in New York City.

If you want to celebrate National Vichyssoise Day, you don't have to go to the Ritz-Carlton; you can easily make this delicious soup at home.

Chop 2 leeks and 1 onion, then sauté gently in 2 tablespoons unsalted butter until soft. Do not overcook and let them brown. Add 3/4 cup thinly sliced potatoes and 2 1/3 cups chicken stock to the saucepan. Add salt and ground black pepper to taste. Bring to a boil and simmer gently for half an hour. Puree the soup in a food processor or blender until very smooth and allow it to cool. Gently stir in 1 1/8 cups heavy whipping cream before serving.
