How to store an onion for maximum shelf life

June 6, 2023

Properly storing onions is essential to ensure that they remain fresh and flavourful for as long as possible. Here are some tips on how to store New Zealand grown onions for the longest shelf life:

  1. Choose the right location: Onions should be stored in a cool, dry, and well-ventilated place. Avoid storing them in areas that are damp, humid, or have exposure to sunlight.
  2. Keep them dry: Moisture is one of the biggest enemies of onions. Therefore, make sure to remove any excess dirt or debris and let them air-dry before storing.
  3. Don't wash them: Do not wash onions before storing them, as this can introduce moisture and promote spoilage. If necessary, gently wipe them with a dry cloth or paper towel.
  4. Store them in a mesh bag: Storing onions in a mesh bag or a basket allows for proper ventilation and air circulation, which can help to prevent them from rotting.
  5. Separate them from other produce: Onions release ethylene gas, which can cause other produce to spoil faster. Therefore, it is best to store them separately from other fruits and vegetables.
  6. Check regularly: Onions can start to spoil or sprout over time, so it's essential to check them regularly for any signs of damage or deterioration.

By following these simple storage tips, you can ensure that your New Zealand grown onions stay fresh and flavourful for up to many months. This can save you money, reduce food waste, and ensure that you always have delicious and healthy onions on hand for your favourite recipes.
