Print Friendly, PDF & Email

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

When an onion is cut, don’t peel it, and put it in a Ziploc bag. Push out as much air as possible. Seal.

Store it in your refrigerator’s crisper. 

It will stay fresh for 2 weeks.

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

Place sliced, chopped, or cubed onions in an airtight container, and place them in the fridge. 

It will stay fresh for 1 week. 

4. Freeze the onions

Place the sliced, chopped, or cubed onions, in a thin layer, in a Ziploc bag. 

Freeze it in the freezer. 

When you use it, just take out the portion that you need. It’s best to use it in cooking like stir-fry or soup. It won’t be good as a salad because the texture will be softer. 

It will stay fresh for up to 6 months.

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

For some reason, you must put whole onions in the fridge. It could be you live in a hot and humid place. Here’s how you can do. 

Wrap each onion in paper towels. Place them in a paper bag or cloth bag, so it will have good air circulation. 

Place the bag in the fridge’s crisper. 

It will stay fresh for 1 to 2 months. 

Ps: This method is perfect for sweet onions.
