Gromperekichelcher are traditional Luxembourgish potato fritters made from grated potatoes, onions, eggs, flour, and parsley. The mixture is seasoned with salt, pepper, and sometimes nutmeg, then shaped into small patties and fried until golden and crispy. These fritters are commonly served as a street food or side dish and are particularly popular at fairs and festivals in Luxembourg. Gromperekichelcher are typically eaten hot, either on their own or with accompaniments such as apple sauce, salad, or a dollop of sour cream.
The name "Gromperekichelcher" comes from the Luxembourgish words for "potato" (Gromper) and "fritter" (Kichelcher).
