Originating from the historical region of Red Ruthenia, these soft, crescent-shaped dumplings are filled with a combination of potatoes and cheese, which is occasionally modified with various seasonings or fried onions. Pierogi ruskie are usually boiled and shortly fried until they develop a crispy texture.

The dumplings are often served sprinkled with cracklings, crispy fried onions, or bacon, and can be enjoyed as a hearty appetizer or as a main course. In Ukraine, the pierogis are called varenyky, and they are so popular that there is even a monument celebrating varenyky in the city of Cherkasy. The sweet, fruit-filled version of varenyky is typically served with sugar and sour cream.
