The invention provides a mounting bracket and an embedded cooking device. The embedded cooking device can be mounted in a mounting cavity of a cupboard, and is provided with a buckle for clamping withthe mounting bracket; multiple clamping positions are arranged on the mounting bracket, and are staggered by a certain distance in the width direction of the mounting cavity; the mounting bracket canbe fixedly mounted on the opening edge of the mounting cavity; and one of the multiple clamping positions is selectively clamped with the buckle. The mounting bracket is provided with multiple clamping positions; and the multiple clamping positions are staggered by a certain distance in the width direction of the mounting cavity, so that cupboards with different plate thicknesses can select the clamping positions on the mounting bracket according to actual conditions, the clamping position in the proper width position is clamped with the buckle on the embedded cooking device, and the excellent fixing effect on the embedded cooking device can be achieved under the condition of difference between the width of the mounting cavity of the mounting bracket and a preset value.
