What Polish thin pancake is commonly filled with cheese or jam?

What Polish thin pancake is commonly filled with cheese or jam? Nalesniki, more precisely written naleśniki, is the answer.

Naleśniki are thin Polish crêpe-style pancakes made from a pourable batter and cooked in a pan. They are typically filled after cooking, then folded into triangles or rolled into tubes. Sweet versions commonly use jam, fruit, or soft white cheese—often farmer’s cheese or quark mixed with sugar.

The same pancakes can also be savory. Typical fillings include mushrooms, meat, vegetables, sauerkraut, or cheese. A breaded and fried preparation made from filled naleśniki is known as krokiety, a Polish dish that is easy to mistake for a separate pancake variety.

Naleśniki should not be confused with pierogi, which are boiled or fried filled dumplings made from a thicker dough. Kopytka are potato dumplings, while pączki are filled doughnuts. The spelling without Polish diacritics, “Nalesniki,” is a common English-language rendering and does not change the answer.
