Vichyssoise is a cold, creamy soup made primarily with potatoes and leeks, usually blended until smooth and served chilled. The unusual name suddenly attracted attention in the U.S. after vichyssoise appeared in the August 23, 2026, NYT Connections puzzle, where it was grouped with other foods made with potatoes.
For many people who encountered the word in the puzzle, the problem was simple: they knew neither what “vichyssoise” meant nor how to spell it. Discussions among Connections players show that some searched for the definition after seeing it on the game board, helping explain the sudden interest in the term.
What is vichyssoise?
Vichyssoise is traditionally prepared from potatoes, leeks, onions and cream. The ingredients are cooked, puréed and served cold, often with chopped chives as a garnish. Unlike most potato soups, which are commonly served hot, vichyssoise is specifically associated with being chilled.
The soup has a very smooth texture and a mild flavor. Potatoes provide the body of the soup, while leeks give it a gentle onion-like flavor. Cream adds richness without making the soup heavily seasoned or spicy.
Despite its French-sounding name, the modern dish is closely associated with New York City.
Why is vichyssoise trending?
The immediate reason for the current search interest is the August 23, 2026, NYT Connections puzzle, Puzzle #1169.
The puzzle included vichyssoise as one of four answers in the category “Made with potatoes.” The other three were home fries, potato battery and vodka.
That was an especially difficult connection for some players because vichyssoise is not a food that many people encounter regularly. Comments from Connections players show several people saying they had to look up the word or did not realize it was a soup made with potatoes.
There was another reason the word received attention: the spelling on the puzzle was reportedly shown as “vischyssoise” rather than “vichyssoise.” Players noticed the extra “s” and discussed the apparent spelling error extensively. Some players said the spelling confused them while trying to determine the category. Reports indicate the spelling was later corrected.
The correct spelling is vichyssoise.
How do you pronounce vichyssoise?
The name can look intimidating, but it is generally pronounced approximately “vee-shee-swaz.”
It comes from the French name Vichy, a city in central France, combined with the French feminine adjective ending associated with Vichy.
The word itself dates to the early 20th century, with early English references appearing in connection with the dish served at the Ritz-Carlton in New York.
Who invented vichyssoise?
Vichyssoise is generally credited to Louis Diat, a French-born chef who worked at the Ritz-Carlton Hotel in New York.
According to a 1950 New Yorker interview with Diat, he developed the chilled soup in the summer of 1917 after remembering the potato-and-leek soup he had eaten during his childhood in France. He adapted that memory into a cold soup for Ritz-Carlton diners and named it crème vichyssoise glacée.
Diat's account describes the soup as a purée of potatoes and leeks enriched with cream and served chilled. It became popular enough that it eventually appeared on the Ritz-Carlton menu throughout the year.
The history is slightly more complicated than simply calling Diat the first person ever to make potato-and-leek soup. Similar hot potato-and-leek soups existed in French cooking long before the 20th century. What made vichyssoise distinctive was the cold preparation and its association with Diat's version at the Ritz-Carlton.
Is vichyssoise served hot or cold?
Traditionally, cold.
That is one of the easiest ways to distinguish vichyssoise from ordinary potato-and-leek soup. The soup is cooked first and then chilled before serving. Some historical accounts note that similar potato-and-leek soups were traditionally served hot, which makes the chilled version particularly distinctive.
Vichyssoise is often associated with summer dining because its cool, creamy texture makes it suitable for warm weather.
What is vichyssoise made of?
A traditional version generally includes:
- Potatoes
- Leeks
- Onion
- Cream
- Milk or stock, depending on the recipe
- Butter
- Chives or other seasoning for garnish
Recipes can vary. Louis Diat's documented version used potatoes, leeks, onions, cream and milk, while later versions have used chicken stock and other variations.
Is vichyssoise actually a French dish?
This is where the history gets interesting.
Vichyssoise has a French name and was inspired by French cooking, but the modern soup is strongly associated with New York City, where Louis Diat developed his version at the Ritz-Carlton. A 1950 New Yorker account describes Diat himself explaining how he transformed his childhood potato-and-leek soup into the chilled dish served at the hotel.
So calling it simply a traditional French soup misses an important part of its history. It is better described as a French-inspired chilled soup that became famous in New York.
Why are people searching for vichyssoise now?
There is no indication that vichyssoise suddenly became a major new food craze. The current attention appears to be primarily puzzle-driven.
When an unfamiliar word appears in a popular daily word game such as NYT Connections, players often search for its meaning immediately. In the August 23 puzzle, vichyssoise was particularly effective at creating that reaction because recognizing it as a potato-based food was necessary to solve one of the categories.
The spelling controversy added another layer of interest, with players discussing whether the unusual spelling was deliberate or simply an error.
In other words, vichyssoise is trending because people encountered an unfamiliar word in NYT Connections and went looking for the answer.
The Bottom Line
Vichyssoise is a chilled potato-and-leek soup, traditionally made creamy and smooth with ingredients such as onions, cream and milk. It is generally credited to chef Louis Diat, who developed the famous version at New York's Ritz-Carlton in 1917.
Its sudden popularity in searches on August 23–24, 2026, appears to be connected to NYT Connections #1169, where vichyssoise was one of the foods in the “Made with potatoes” category. The unusual word and a reported spelling error on the puzzle helped make it particularly memorable for players.
So, if you saw “vichyssoise” trending and wondered what everyone was talking about, it is not a new internet slang term or celebrity name. It is a nearly century-old chilled soup that suddenly found itself at the center of a very modern word-game conversation.
