A food package assembly of the type designed to serve the dual function of providing a package for shipment and storage of a prepared food and of microwave heating of the food in a manner producing a browning or crisping effect that is particularly adapted to the needs of foods, such as French bread pizzas and garlic bread, which cannot be crisped in a microwave oven via the use of a single planar microwave interactive crisping layer and which, due to the grease and/or vapor driven out of them cannot be heated in a microwave oven in a closely confined manner without becoming soggy. In accordance with preferred embodiments, a food product is received upon an inner tray member that coacts with an outer package body to cradle the food product so that the adjoining surface thereof will be crisped by a microwave interactive heating layer applied to the facing surface of the inner tray member. Additionally, venting is provided through openings at opposed ends of the outer package body and via venting channels formed between side wall portions of the inner tray member and adjoining inner wall portions of the outer package body, communication between the top side of the inner tray member and the venting channels being provided via venting holes and/or end edge recessing or notching in accordance with various embodiments.
