An electrically heated cooking grill for rapidly cooking cheese sandwiches, hamburgers, french toast, bacon, pancakes, crepe suzette (thin pancakes), pizza crust, scrambled eggs, and other food products. The food products are conveyed between a pair of endless heating belts which are heated by upper and lower heating units in the form of heating platens which have variable temperature heating zones so arranged that the cooking temperature is varied as the food product moves through the variable temperature heating zones. The upper heating unit includes front and rear upper heating platens which are vertically adjustable with the upper heating belt relative to the lower heating unit or platens and heating belt to provide for food products of varying sizes and thicknesses and the front and rear upper heating platens may be tilted relative to the horizontal so that as the food product moves progressively through the grill from front to rear and shrinks in size due to the cooking operation the front and rear upper heating platens and the upper heating belt will be disposed in the most advantageous heating position relative to the lower heating belt and heating unit or platens. The endless heating belts are designed to be nonsticky and to provide for rapid heat transfer from the heating units or platens to the food products being cooked and for long wear life.
