To prevent localized overheating in food products which are to be heated in a microwave oven, an expandable vessel is operatively connected to a food product. When heated the vessel expands moving the food and thereby distributing non-uniformly distributed microwave energy more evenly throughout the food. In one embodiment, the vessel is a folded or coiled bag which retains steam and vapor evolved during the heating operation. The vapor expands the bag causing it to unfold i.e., straighten out thereby moving the food product from one location in the oven to another as microwave energy is applied.

A method for more uniformly exposing food products to microwave energy comprising, providing a package containing a vaporizable liquid having a food-filled portion and an expandable vessel, providing contact between the vessel and the food-filled portion, exposing the food-filled portion and the vessel to microwave energy sufficient to heat the food and vaporize the liquid to cause expansion of the vaporized liquid in the vessel, the vaporized liquid causing the vessel to expand and push against the food-filled portion to change the location thereof in the oven and thereby force the food to move bodily from one position to another with respect to the oven as a result of the expansion of the vessel and the resulting movement of the food distributing non-uniform microwave energy more uniformly in the food product, the vessel being vertically expandable and the food-filled portion being positioned on top of the vertically expandable vessel whereby expansion of the vessel moves the food-filled portion upwardly in the oven when the vessel is exposed to microwave energy.
