A food cooking device includes a housing with an inclined platen or top surface mounted thereon. A heating assembly for heating the platen is included in the housing along with a drawer into which food items may be placed for warming. A grid including a plurality of rods extending transversely across the inclined platen is slideably mounted on the platen and connected by a linkage assembly to a rotary motor. The linkage assembly translates the rotary motion of the motor to linear reciprocating motion that is imparted to the grid. Food items may be positioned on the platen between adjacent rods to be moved a predetermined distance over the platen by the reciprocating rods to ensure cooking on all sides of the food item.
