Instead, whole onions should be stored in a cool, dark place, such as a pantry or cellar, with good air circulation. This will help to maintain their texture and flavor for a longer period of time. If you need to store cut or peeled onions, it’s best to wrap them tightly in plastic or aluminum foil and place them in the fridge.
