The invention relates to a soup food material processing method of an air fryer, the air fryer comprises a machine base, a processing assembly, a hot air assembly and a steam assembly, the machine base defines a working space, the hot air assembly heats food materials, and the steam assembly generates and injects steam into the working space. The processing method at least comprises an air fryingstage and an original taste steaming stage which are carried out in sequence, in the air frying stage, a hot air assembly injects hot air into a working space to heat the working space to a preset temperature T1, hot air is used for surrounding and heating food materials to cook the food materials, and T1 is larger than or equal to 110 DEG C; and in the original taste steaming stage, the steam assembly injects steam into the working space so as to steam the food materials. An air frying stage and an original taste steaming stage are set, so that the boiling state of soup food materials is improved, and the nutrition and flavor quality of the soup food materials are improved. And compared with cooking processing only depending on hot air circulation, the original taste steaming stage is added, so that excessive loss of water in the soup food materials is avoided, and the soup food materials can be kept more nutritious and juicy.
