How to Store Potatoes and Onions the Right Way

You know that potatoes shouldn’t be kept in the refrigerator. But it’s easy to think that potatoes and onions should be stored together in the pantry. Here’s the truth—storing them together might not be the best idea.

Can I Store Potatoes and Onions Together?

Sure, spuds and bulbs are tasty when combined together in meals. But they should actually be stored far away from one another.

Why? Your onions produce and emit ethylene gas, which speeds up the ripening process and can cause nearby potatoes to rot and spoil more quickly. However, garlic, another root bulb, can be safely stored alongside onions with no scary side effects. By the way, here’s what to do when potatoes turn green.

How to Store Potatoes

Your potatoes should be stored in a cool, dark, dry place, such as a pantry or cupboard for up to 5 weeks. Use a storage container that is well-ventilated, such as a crate, a cardboard box with holes punched in it, or any container that will allow any excess moisture to evaporate.

Keep the container covered to block light and prevent your spuds from spouting. If your potatoes have gone soft, wrinkled or have sprouted more than a few centimeters, they’ve likely gone bad. Here’s more on if you can eat sprouted potatoes.

How to Store Onions

Onions should also be kept in a ventilated space, such as your countertop for up to 3 months. You can keep them in a paper bag or even a wire basket. It isn’t necessary to store onions in the refrigerator, as the cold temperature will quickly soften their texture. A softened texture and moisture spots are a sign the onions have spoiled.
