Versatile Potato Leek Soup

Potato leek soup is the Swiss army knife of all soups. It’s extremely versatile and simple to make, allowing you to customize to fit your tastes and dietary needs. Every element can be modified: puree or don’t puree; use water or use stock; use milk or cream or no dairy at all. Whatever decisions you make the soup will still taste amazing. That is the simple beauty of potato leek soup.

This soup, though born in a modest farmhouse, has graced the tables of many a fancy restaurant. In the old days, potato-leek was more commonly called soupe bonne femme or ‘good wife’ soup. French American chef Louis Diat introduced a cold version called vichyssoise in 1917. He claimed he invented the soup near Vichy, France with his brother. What he neglected to mention to his adoring fans was that he got the recipe from his mother, though she served it hot. Traditionally soupe bonne femme was served unpureed and garnished with croutons made from leftover bread fried in oil. This soup is so flexible, you can garnish it with literally anything. I even have used leftover cacio e pepe.
