Abstract: An assembly for packaging a frozen food is adapted to be exposed to microwave energy such that the frozen food is processed and, in particular, defrosted efficiently from its solid to its liquid state. The assembly includes a container normally disposed on the bottom, and a cover normally disposed on the top of the assembly and adapted to be releasably engaged with the container to form the assembly. When assembled, the cover and container support in a generally upright orientation the frozen food. The cover includes means for supporting only a top portion of the frozen food, while exposing the bottom portion of the frozen food directly to microwave energy.
