A removable pan used to adapt a cooking grill to a meat smoker. The pan can be placed into a conventional backyard cooking grill to convert the grill into a meat smoker. The pan has a central section, a raised perimeter, and at least three tabs extending outwardly from a center of the pan. The tabs can be positioned on the horizontal surface that supports the cooking grate of the grill. The cooking grate is then positioned atop the pan. The pan functions as a heat sink and provides indirect heating. The pan can also optionally be filled with a liquid like water for additional temperature control and to affect the humidity within the grill. The presence of the liquid can impact the moisture and flavor profile of the meat being smoked.
