I typically buy a 3-5lb bag of onions. Once I bring them home, I take them out of the mesh packaging and place them in plastic Ziploc bags. The onions are kept stored in the crisper drawer of my refrigerator, and used frequently.
Many will argue that onions should be kept in a cool climate outside of the refrigerator, but that is not always available. Regardless of where you live, the way you set your thermostat may defeat the purpose of storing them outside of the refrigerator.
If you live in the south, and the air conditioner is being used, that still may not keep the onions cool, depending on the direction of airflow The same goes for living in the north, depending on how hot it gets in the summer, and how high you turn the heater up in the winter.
Storing whole onions in plastic, in the consistently cool refrigerator helps them maintain their freshness for weeks.
This storing practice has worked for me for over 30 years. I use onions in most of the recipes I prepare because of the flavoring it adds to food.
- Get the most value for your dollar by buying onions by the bag, usually available in 3-5lb bags.
- Remove from the mesh packaging.
- Place into plastic Ziploc bags.
- Place in a refrigerator, in an uncluttered crisper drawer.
- Never store with potatoes! The chemical reaction speeds up the spoiling of both the potato and the onion.
