The cooking device has an oblong shape that is commensurate with the oblong shape of the poultry cavity to maximize the seasoning of the poultry during cooking. The cooking device has a lid that is securable to a bottom member of the cooking device to prevent spillage of the seasoning during placement of the cooking device in the poultry cavity, and during the removal of the cooking device after cooking. The lid has downwardly extending flanges that secure within a rim of the bottom member to both lock and seal the lid in place. A handle allows safe placement and removal, of the cooking device, such as when the poultry is already in an oven, to prevent burns.
