As an avid home cook and former pro baker, I’ve always looked at onions as a flavor builder more than anything else. They’re the foundation of many recipes, and they can even improve your health, according to researchers. When you eat them regularly, onions can potentially support your digestive, heart, and eye health. Onions also naturally possess antibacterial properties, and they may be able to lower your cancer risk.

All of that for a root vegetable? Yes. But they’re only as good as they are fresh. A spoiled onion is one that’s overly sprouted, soft, dry, or moldy, and it’s not very useful for flavor building or for health boosting. Since onions are often purchased in bulk, storing your bulbs correctly is important, especially as holiday festivities approach. Onions spoil when they’re exposed to light, moisture, and excessive heat. To avoid those conditions, I always keep mine in a wire basket in my pantry, and they’ve lasted for months with this method.

This basket is similar to the one I own, which is no longer available. The open wire design allows for air circulation, which is key to staving off spoilage. Proper ventilation helps prevent moisture buildup. I’ve stored many alliums (like garlic, onion, and shallots) in containers only to find that the lack of air can accelerate spoilage. The same goes for the refrigerator, which is a high-humidity environment. I’ll always put my basket into my pantry because it’s cool, dark, and dry.

In addition to its wire material, this bowl’s size and shape can help keep onions fresh. It’s round, so it’ll fit large, bulbous alliums neatly. The wide diameter (11 inches) allows you to place several onions in one layer, which is another effective storage tactic. Less stacking means more breathing room!

Because of the bowl’s airy design, shoppers say produce like onions “get plenty of air.” One reviewer loved it so much, they bought three for their onions, bread and potatoes. With over 1,000 perfect ratings, it’s safe to say that this basket is a certifiable staple.

So get the most out of your onions by keeping them on hand, fresh and ready to use. A wire basket placed in a cool, dry area is a tried-and-true way to do this. Oh, and another tip: Never store them with your potatoes! Onions can cause these spuds to spoil faster than you can eat your Thanksgiving plate.
