The invention discloses a method for preparing aromatic rapeseed oil. The method comprises the following steps: (1) wetting and tempering, namely feeding rapeseeds into a wetting device, spraying water for wetting, and conveying the rapeseeds into a tempering device for tempering; (2) frying and smoking, and removing the glucosinolate decomposition products; (3) pressing to prepare crude rapeseed oil; and (4) crystallizing and filtering the crude rapeseed oil, thereby obtaining the aromatic rapeseed oil. The preparation method disclosed by the invention is simple and easy to operate, any chemical additive does not need to be added in the preparation process, the wastewater and waste gas pollution is avoided, the prepared aromatic rapeseed oil is strong in flavor, the content of total glucosinolate is extremely low, the residual oil content of the rape seed cake is low, and the oil extraction efficiency of the rapeseeds is high.
