A smoke generating assembly for an indoor smoker includes a smoke barrel having a rotating auger positioned therein. The smoke barrel may be supplied with combustible material at a first end of the smoke barrel and the auger may be intermittently rotated to advance the combustible material toward a second end of the smoke barrel and over a smoldering heater to generate a flow of smoke. The smoldering heater may be spaced apart from the smoke barrel by an igniter gap that permits pellet dust from the combustible material to fall into the container below, leaving only solid combustible material to pass through the smoldering heater for combustion.
