The present application relates to an apparatus for processing a food stuff. The apparatus has a housing (2) and a cutting tool (5) for cutting a food stuff which is rotatably mounted in the housing. The cutting tool (5) rotates in the housing (2) about a rotational axis and has a radially extending cutting element (44). One end of the cutting tool (5) slides in a circumferentially extending slot in the housing as the cutting tool (5) is rotated in the housing (2). Therefore, the cutting tool (5) is supported in an axial direction by the housing (2). The present application also relates to a food processor.
