The present disclosure relates to a shifting control method that improves driving stability by reducing roll-back of a vehicle during the process of shifting on an uphill slope. The shifting control method for a hybrid vehicle includes: determining a degree of roll-back of the vehicle on the basis of a change in the number of revolutions of a transmission input shaft, when power-off down-shifting into a lowest gear is requested; decreasing a disengaging clutch torque, increasing an engaging clutch torque, and increasing a motor torque so that the motor torque follows a desired motor torque, when the degree of roll-back is equal to or greater than a set value; synchronizing a motor speed with an engaging input shaft speed by decreasing the motor torque, when the disengaging clutch torque is equal to or less than a set torque; and finishing the shifting by increasing the motor torque when the synchronization is finished.
