Origins of the Potato Knish
Eastern European Roots
The knish originated in Eastern Europe, particularly among Ashkenazi Jewish communities in countries like Poland, Lithuania, and Ukraine. The word knish itself comes from the Yiddish word knish, which is believed to be derived from a Ukrainian or Polish word meaning ‘pastry.’ This hearty food made its way to the United States with Jewish immigrants in the late 19th and early 20th centuries, quickly becoming popular in New York City’s Jewish neighborhoods.
A Food of the People
Originally, knishes were considered affordable, satisfying street food. Street vendors and bakeries sold them in large quantities because they were inexpensive to make and filling enough to serve as a small meal. Over time, the knish became symbolic of Jewish-American cuisine, especially in cities like New York where cultural food traditions have remained strong.

While potatoes are the most traditional filling, other versions include ingredients like kasha (buckwheat), meat, sauerkraut, or even sweet fillings.

Although there are slight regional and personal variations, a classic potato knish usually includes the following components:
- Filling: Mashed potatoes seasoned with salt, pepper, sautéed onions, and sometimes other herbs or spices.
- Dough: A flour-based dough that may be enriched with oil or egg for elasticity and flavor.
- Shape: Round, square, or rectangular, depending on how it is folded and prepared. Some are bite-sized, while others are large enough to be a full meal.
