5 Ways to Store Onions for Long Term (Weeks, Months, or 1 Year)

Hi everyone! It’s CiCi here. Today let’s take a look at how we can store onions for long term (Weeks, Months, or 1 Year).

There are many types of onions out there. Generally speaking, the onions that store well are the ones that have thicker outer skins, a higher sulfur content, and lower water content. 

For example, these store-bought Yellow Onions are great for storage because they have thicker skin. On the other hand, Sweet Onions may not last that long because they have thinner skin. 

5 ways to store any types of onions for longer 

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

Put onions in a mesh bag, paper bag, or basket. Place it in a dark, dry, and cool place with good air circulation. The ideal temperature is between 40 to 50 degrees F (4 to 10 degrees C) 

Don’t store onions with potatoes. Onions will go bad faster next to potatoes. 

The onions will stay fresh anywhere from 3 to 12 months, depends on the types of onions and their conditions. 

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