Best Practices for Storing Onions in the Refrigerator

Onions are a staple ingredient in many kitchens, but storing them can be a bit tricky. If you store onions improperly, they can start to sprout and rot quickly. One popular method of storing onions is in the fridge, which can help extend their shelf life by up to two months.

However, there are some tips and tricks that you need to know before you start storing onions in your fridge. Here’s everything you need to know about how to store onions in your fridge:

Choose the Right Onions

Not all onions are fit for storage in the fridge. You should choose fresh, firm bulbs with dry outer layers that aren’t damaged or bruised. Avoid buying any onions with soft spots or other signs of decay as they will spoil faster once placed inside the refrigerator.

Prepare Your Onion for Storage

Before placing your onion into the refrigerator, it is important to prepare it properly. First off remove any dirt from its surface then let it dry out completely before proceeding so no moisture remains on the skin of an onion as this may lead towards decay during refrigeration.

Cut or uncut?

One common question people have when storing onions in their refrigerator is whether they should cut them first or not? The answer is simple: leave them whole if possible! Cutting an onion exposes more surface area that can accelerate spoiling; however, if necessary for recipe purposes don’t hesitate using cut pieces just make sure these are wrapped up tightly.

Pick Your Storage Container

When choosing containers for onion storage within a refrigerator select ones made of plastic bags or any kind of material allowing air circulation around onion while keeping its humidity level intact since too much moisture leads towards rotting quicker than usual due over-hydration processes taking place within our vegetables!

Sealable plastic bags work great because they keep air and moisture out while also allowing the onions to breathe. You can also use an airtight container, but make sure it has plenty of ventilation holes.

Store Your Onion in the Right Place

It is essential that you store your onions in the right place inside your fridge. The best area for storing them is at the back or bottom shelf of the refrigerator where humidity levels are high and temperature remains constant.

Avoid placing onions near other produce like fruits, which release gases such as ethylene that can accelerate spoilage. Keep them away from any sources of moisture, so they won’t get damp and moldy while stored in there – this includes areas around condiments or liquids cans.

Additionally, when keeping chopped onion pieces covered up tightly within a storage baggie helps keep their smells from spreading out all over our food causing unpleasant flavors throughout!


By following these tips mentioned above, you’ll be able to extend your onion’s lifespan significantly by storing them correctly in your fridge with maintaining proper airflow around each bulb wrapped into plastic bags. Not only will it save you money on groceries over time due to less waste but also help cut down odors produced by decaying matter found inside fridges!
