The present invention in various embodiments provides an oven system, having movable heating panels adapted to a partitioning mechanism, to change the heating chamber into one or more compartments in the housing, as per user requirements. The partitioning mechanism with the movable heating panels may be adapted to the extendable member or walls of the oven chamber including base, side walls or top wall of the oven chamber. The rotational holders may be adapted in the extendable member or the base of the oven chamber for adapting the skewers or food holders. Thus, the present invention creates an oven system which allows the user to maximize and optimize the use of the oven system in a more effective way.
