The invention discloses a salted goose processing method. The salted goose processing method comprises the following steps: (1) slaughtering and cleaning a goose; (2) covering the goose carcass with a mixture formed by grinding geranium, xanthoxyli fructus and star anise and then frying the obtained powder with salt; (3) evenly injecting marinade into the goose body, placing the goose into a vacuum tumbling machine after injection to achieve pickling at a low temperature in an intermittent circulatory vacuum mode; (4) placing the processed goose into marinade for pickling, and then taking out the goose, air-drying, disinfecting and vacuum-packing.
