Tips for Long-Term Onion Storage

Onions are a staple in most households due to their versatility, flavor, and health benefits. However, they can be tricky to store long-term without proper knowledge. In this blog post, we will explore the best ways on how to store onions long-term.

Understanding onion storage basics

Before diving into the specifics of storing onions long-term, it’s essential to understand the basics of onion storage. Onions should always be stored in a cool and dry place that is well-ventilated. This means that areas such as cellars or basements are ideal for storing onions as they have consistent temperatures and low humidity levels.

Avoid moisture

Moisture is one of the biggest enemies when it comes to storing onions long-term. When exposed to moist conditions, onions tend to sprout faster than usual or even rot altogether if left unchecked for too long.

To avoid moisture buildup around your stored onions, consider using an open wire basket or mesh bag instead of plastic bags since these do not trap air around them leading up too much condensation build-up inside your storage container.

Separate different varieties

Different types of onions ripen at varying rates; some mature faster than others do. To prevent cross-contamination between differently aged onion batches, consider separating each variety from one another during storage by placing them into labeled baskets or containers accordingly – so you’ll know which batch came first every time you want an onion!

Tips on how to keep your onions fresh longer

Longer-lasting freshness equals more flavorsome meals! Here are some tips on how you can extend the shelf life of your stored-onions:

Clean before Storage

Clean any dirt off your harvested bulbs before putting them away for storage because leftover soil particles may lead up faster rotting than if they were clean beforehand.

Also note that washing your onions immediately before storage shortens their lifespan. The water left on the surface of your bulb might cause humidity to build up inside, leading to quicker spoilage.

Use a Dark Place

Onions tend to last longer when stored in darkness than they do when exposed to light. This is because sunlight can trigger onion bulbs’ sprouting process faster than if kept away from it altogether.

Consider storing them in opaque containers or wrapping each onion in brown paper bags for more extended shelf life with reduced exposure to light.


Knowing how to store onions long-term will not only save you money but also ensure that you always have flavorful and healthy onions at hand. By following these tips, you’ll be able to keep your onions fresh for an extended period. Remember, proper storage means better-tasting meals!
