Abstract: An improved sleeve receptacle for microwave browning and crisping of a generally flat food article, such as pizza, in a microwave oven is provided. The receptacle is constructed from a sheet of microwave susceptor stock which preferably includes an outwardly exposed dielectric support layer and an inwardly facing heating layer of microwave interactive material allowing passage of microwave energy as it is heated thereby. The sleeve is initially provided as a flat sheet which can be easily fitted within the frozen food package. The consumer folds the flat sheet into its sleeve configuration by joining the top portions of the sleeve together in a manner whereby the top portions of the sleeve can be later pulled apart to permit easy removal of the heated foodstuff.
