Storing Sweet Onions

Ask the Test Kitchen

Is there any way to store Vidalia onions? I would like to buy them in quantity when they’re in season. —L.L., Brick, New JerseyVidalia and other sweet onions are mild-flavored onions that are high in sugar and water content and low in tear-inducing sulfur compounds. Because of these properties, they are not suited for long-term storage, so you should use them within several weeks of purchase. Fortunately, different varieties of sweet onions are available almost all year long, so while you may not find Vidalia, you should be able to find other types of sweet onions at your grocery store.When storing sweet onions, it’s important to keep them cool, dry and separate. Place in a single layer, wrapped separately in foil or paper towels, in the vegetable bin of the refrigerator. If it is not possible to store them in the refrigerator, store them in the coolest area of your home with good air circulation.
