A food storage container includes a lid with a vent hole, and a removable cover removably secured to the lid to cover the vent hole. The cover has an evacuation hole. The food storage container further includes a one-way air valve disposed between the vent hole and evacuation hole. When the cover is secured to the lid, the one-way air valve inhibits air flow into the container through the vent hole, and when the cover is not secured to the lid, the one-way air valve allows air flow into the container.
