A laser processing method is performed in a laser processing apparatus which outputs a laser beam from a processing head to a workpiece, to perform laser processing while controlling reflected light of the output laser beam to a prescribed value or less. The laser processing method includes the step of, before performing laser processing for the workpiece, increasing laser power stepwise from laser power lower than laser power included in a processing condition of the laser processing, to emit a laser beam from a laser oscillator, and measuring reflected light by a reflected light sensor, and the step of deciding an output condition for decreasing reflected light based on a measured value of the reflected light and the prescribed value, and the step of decreasing reflected light before performing the laser processing by irradiating the workpiece with a laser beam for a predetermined period of time on the decided output condition.
