Potato soup couldn’t exist until potatoes were introduced to Europe in the late 1500s (they originated in the Andes of South America). Once potatoes spread across Europe in the 1600s–1700s, potato-based dishes — including soups — began to appear.
There is no single inventor of potato soup; instead, it developed in multiple regions where potatoes became common.
As potatoes became a staple in Ireland, Scotland, Germany, and northern France, simple potato soups appeared as cheap, filling, rural meals.
These early soups were:
Thick, rustic, and hearty
Often made with potatoes, onions, water or broth, and sometimes milk
Practical for areas with tough winters or food shortages
Many early versions were closer to “potato porridge” than the creamy soups we know today.
France played a key role in shaping modern potato soup.
A famous French potato-leek soup named after Antoine-Augustin Parmentier (1737–1813), who heavily promoted the potato as a food crop in France.
The dish became popular in the late 1700s.
It combines potatoes, leeks, broth, and cream or butter.
It’s considered the ancestor of many modern creamy potato soups.
A chilled potato-leek soup, likely invented in the early 1900s by Louis Diat, a French chef at the Ritz-Carlton in New York.
These French soups helped elevate potato soup from a peasant dish to a refined staple.
Potato soup also developed in:
Germany (Kartoffelsuppe)
Poland (Zupa ziemniaczana)
Russia and Eastern Europe
These versions often include:
Sausage
Root vegetables
Herbs
Broth-based preparations
They are still common comfort foods today.
European immigrants brought potato soup recipes to North America.
By the 1800s, American cookbooks included several kinds:
Creamy New England potato soups
Brothy pioneer-style soups
Potato chowders
Potato-and-cheese soups
Potato soup became popular because potatoes were inexpensive and widely grown.
