A cooking appliance includes a body that defines a cooking cavity, a door that defines a storage pocket, and a partition. The door is movable relative to the body between a closed position, wherein the door covers an opening to the cooking cavity, and an open position, wherein access to the cooking cavity is provided. The partition is operable between a stowed condition, wherein the partition is disposed within the storage pocket defined by the door, and the use condition, wherein the partition is positioned within the cooking cavity and divides the cooking cavity into a first sub-cavity and a second sub-cavity.
