A cooking grill of the type having a grill body has a heat producing element and a grill element defining a cooking surface on which food is placed to be cooked. The cooking surface is spaced above the heating element, with a grease pan supported within the grill body, intermediate the grill element forming the cooking surface and the heat producing element. The grease pan has a size substantially the same as the cooking surface defined by the grill element and includes a grease outlet at a bottom surface thereof. The gas grill includes a grease reservoir mounted externally of the grill body normally suspended from a bottom surface thereof. A grease collection system is housed within the grill body and extends between the grease outlet on the bottom surface of the grease pan and the grease reservoir. In order to facilitate the flow of grease from the grease pan to the reservoir, the bottom surface of the grease pan slopes downwardly towards the grease outlet.
