Abstract: A multiple stage oven structure including a radio frequency cooking station and an infra-red cooking station particularly useful for cooking certain food products. The radio-frequency cooking station comprises a first and second electrode and a conveyor to position the food product between the electrodes wherein it is the dielectric material of a capacitive heating assembly. Also disclosed is an automated food cooking and serving arrangement incorporating the multiple stage oven structure with a food storage section and associated conveyors and electronic control components for conveying the food product through various steps of selection, cooking and delivery of the cooked product to a customer. In a preferred arrangement, the food product is carried by an electrically conductive pan which functions as the second electrode in the radio-frequency cooking station assembly, forms a portion of a radio frequency shield during cooking, and as a serving pan once cooking is completed.
