Abstract: A cooking apparatus includes a cooking surface heated by a heating mechanism and divided into two cooking surfaces by a center seam. A mechanism for preventing grease from draining through the center seam may include either a center grease drain, a ridge along the center seam, or a seal. The cooking apparatus is folded using a hinge, along the center seam, such that the cooking surfaces are separated and disposed on external opposite and parallel sides. A control assembly, which may control the griddle surfaces separately, is removably attached to the cooking apparatus and stored at an underside thereof. The control assembly includes a cover to prevent damage to the control elements. At least one channel with a drain hole therein is disposed at each of the cooking surfaces for receiving cooking fluids, and a removable grease tray disposed beneath the drain hole collects the fluids.
