This invention provides a cup assembly for a food processor, including a cup body, a cup lid, and a processing component disposed within the cup body. It also includes a gearbox, which comprises a movably disposed clutch output shaft. When the clutch output shaft moves to a first position, it drives the processing component to output a first rotational speed; when the clutch output shaft moves to a second position, it drives the processing component to output a second rotational speed. The cup lid is installed in place, maintaining the clutch output shaft in either the first or second position. Furthermore, a food processor with the aforementioned cup assembly is provided. In the first position, the clutch output shaft outputs a first rotational speed to adapt to multi-functional cooking; in the second position, it outputs a second rotational speed to adapt to another multi-functional cooking method requiring a different speed. By changing the position of the clutch output shaft, the processing component can be replaced and the rotational speed can be automatically switched. Moreover, the output speed range is wide and the torque is high, avoiding stalling caused by high processing resistance.
