1. Store onions in a cool, dark, and well-ventilated area
Place onions in mesh bags, paper bags, or baskets. Keep them in a dark, cool, and dry area with good air circulation. The ideal temperature is between 40 to 50 degrees Fahrenheit (4 to 10 degrees Celsius).
Do not store onions with potatoes. Onions will spoil faster when stored with potatoes.
Using this method, onions can last from 3 to 12 months, depending on the type of onion and their condition.
2. Store half an unpeeled onion in a ziploc bag in the fridge
When using onions, if you only need half, leave the skin on the unused half.
Cut the onion in half, peel the portion you plan to use, and leave the rest unpeeled. Place it in a ziploc bag, squeeze out as much air as possible, seal the bag, and store it in the refrigerator.
Onions stored this way will stay fresh for about 2 weeks.
3. Store chopped onions in an airtight container in the fridge
If you have chopped more onions than you need, place the chopped onions in an airtight container and store them in the fridge.
Chopped onions stored this way will stay fresh for about a week.
4. Freeze onions
Spread chopped onions, diced onions, or onion rings in a thin layer on a baking sheet and place them in the freezer. Once frozen, transfer the onions to a ziploc bag.
When you need to use them, just take out the amount you need. They are best used for cooking, such as stir-frying or making spring rolls. They may not be suitable for fresh dishes like salads as they will have a softer texture.
Onions stored this way can last for about 6 months.
5. Wrap whole onions in paper towels, place them in a cloth bag, and store them in the fridge
If you need to store whole onions in the fridge, for example, during humid weather, here’s what you can do: Wrap each onion individually in a paper towel. Place them in a paper or cloth bag to ensure good air circulation. Then, put the bag in the fridge.
Onions stored this way can last for about 1 to 2 months.
Good luck!
