A continuous cooking oven system including enclosure containing a first cooking chamber in communication with a second cooking chamber to efficiently and effectively cook and brown food products. The continuous cooking oven system includes an first conveyor for transporting food products through a helical path within the first cooking chamber, a fan for circulating a heated gaseous cooking medium throughout the first cooking chamber, a second conveyor for transporting food products through a linear path within the second cooking chamber, at least one impingement air flow distribution chamber disposed above the second conveyor within the second cooking chamber and at least one impingement air flow distribution chamber disposed below the second conveyor within the second cooking chamber, the impingement air flow distribution chambers circulating a heated gaseous cooking medium throughout the second cooking chamber. The first conveyor includes a self-supporting pervious belt including a plurality of superimposed tiers which define a pervious annulus through which the heat gaseous cooking medium is circulated.
