A food container preferably for heated food, has a lid member and a base member. The base member has complimentary embossed portions in the bottom of the base member to engage a complimentary indented portion in the top surface of the lid member. The retaining mechanism allows containers to be stacked so as to secure each container while allowing steam to escape from the lid of a container. Also, a fluid return system retains fluid in the container and promotes flow of fluid into the bottom of the container.
