A clamshell grill includes a griddle plate defining a cooking surface and a platen having a sealing member defining a perimeter of an interior cooking cavity. The platen is moveable between a non-cooking position, wherein the sealing member is spaced apart from the cooking surface, and a cooking position, wherein the sealing member is engaged with the cooking surface and defines an enclosed cooking volume. A fluid source may be coupled to the platen and includes an outlet in fluid communication with the enclosed cooking volume, at least when the platen is moved to the cooking position. A platen assembly and methods for the use and assembly of the clamshell grill are also provided.
