A knob safety assembly is operative to selectively restrict depression of a cooking element control knob. The safety assembly includes a blocking plate disposed inside of a bezel assembly. The bezel assembly includes an outer bezel defining one or more angled camming surfaces, and an inner bezel. Rotation of the inner bezel with respect to the outer bezel about a rotational axis slides an ear of the blocking plate along the camming surface to effect movement of the blocking plate along the rotational axis between a raised position, in which the blocking plate restricts depression of a cooking element control knob, to a recessed position, in which the blocking plate facilitates depression of the control knob. The inner bezel is releasably locked from rotating with respect to the outer bezel, and engages the blocking plate to constrain the blocking plate against movement along the rotational axis when locked.
