The present invention relates to a retractable shelf assembly which may be easily mounted within a microwave oven cooking chamber. A pair of elongated substantially rectangular outer track members having an open end are mounted to the bottom of the microwave oven interior adjacent opposing sides. A pair of inner track members are longitudinally and slidably received within the outer track members and telescopable therefrom. A shelf with a pair of open sided channels on opposing edges is attached at an end to the inner track members and slidably engages the outer track members. The telescoping track and channel assembly allows the shelf to be slid horizontally into or out of a microwave oven as desired. A telescoping brace component vertically extends from the upper surface of the shelf component to engage the interior of the microwave thereby preventing the tray from completely sliding off the telescoping track mechanism. The shelf has a recessed area that defines an integral handle and a telescoping handle horizontally extending from an edge of the shelf member which may be used in the event the recessed handle is inaccessible.
