How to Store Onions Long Term

Whether I buy onions at the store or grown them myself I want to be able to make them last a long time so I don’t have to throw them away. So for long term storage I usually keep them in the mesh bag they come in when I buy them and hang the bag in the pantry. My pantry does not have any windows so as long as the door is closed it is dark in there. It also stays cool in there which helps the onions last longer.

I save the mesh bags to use for onions that I grow. I have had better luck growing yellow onions than I have had with white onions. I’m not sure why but when I try to grow white onions I always get really small onions. When I grow yellow onions I tend to get much larger onions which is what I like.

So here are a few ways to store onions according to CiCi in her video below:

1. Store onions outside the fridge in a dry, dark, and cool place with a good air circulation.

2. Store halved onions, don’t peel off the skin, in a Ziploc bag, and place them in the fridge.

3. Store sliced onions in an airtight container in the fridge.

4. Freeze the onions.

5. Wrap whole onions in paper towels, place them in a cloth bag, and put them in the fridge’s crisper.

I store onions that have been peeled or cut in freezer bags and keep them in the fridge. These are for short term use  – usually a few days to  a week or two. After that they start to dry out and lose their flavor and I end up adding them to my compost pile.

Another option that she did not cover is dehydrating onions. I have a Cosori dehydrator and have found that it does a great job with onions. One tip though is to make sure you dehydrate onions outside. I did them in my kitchen the first time and I didn’t think the smell would ever go away. The onion smell gets very strong during the dehydrating process.

Freeze drying onions is also an option if you have a Harvest Right Freeze Dryer at home. I don’t have a freeze dryer but I do buy freeze dried onions at the grocery store or off of Amazon when they are on sale. Freeze dried onions and dehydrated onions are great to use when making soups and stews.
