Using a food dehydrator is the most convenient way to dry green onions. You can also use your oven for the process if a dehydrator is not available.

  • Preheat the food dehydrator at 95F – 125F/35C – 52C.

PRO TIP – when dehydrating fruits or veggies, always make sure to preheat the dehydrator beforehand – at the proper temperature. Setting the heat higher, doesn’t really speed up the dehydration process. It may only cause your fruits or veggies to harden.

  • Cut off the root ends. Before washing the green onions, cut off the root ends first. This way, you get to save on time and water that you would otherwise consume in cleaning the parts that you would only discard later. After all, you can’t compost or replant the parts later.

If there’s a little of the white bulb left, and parts of the green leaves show, you can re-plant it in your small kitchen garden if you have one.

  • Wash and strip. Make sure to get rid of all debris that may be left hanging out in the leaves. Likewise, strip the outer layer off if it is about to come off.
  • Chop the onions into small and uniform pieces. The chopped pieces must have a uniform size. This way, they will dehydrate equally. It is a good idea to separate the onions at the natural point of separation between the leaves and the stem.

The green onion’s white bulbous part possesses a more pungent flavor compared to the milder leaves. They can thus be stored and used separately.

  • Separate the white rings (if preferred). The vegetable’s white portions are denser, but they can be separated. By separating the white parts, you can ensure that everything will dehydrate at the same time. If you leave the white portions intact, they will take a longer time to dry up.

You can opt to split the green onion’s bulbous part. You can likewise use a chopstick or a fork to poke through the veggie, and split the layers. While this step is not really necessary, it can help in shortening your total dehydrating time.

  • Lay down the chopped green onion pieces on dehydrator trays. Allow the veggies to dry for 3 to 5 hours at a preset temperature of 95F – 125F. While most dehydrators would recommend drying green onions at 125F, dehydrating at a lower temperature will help keep the nutrients intact. It means you can dehydrate green onions at 95F/32C as well, but it will take more time.

PRO TIP. Treat green onions as herbs, and as such, should be dried under lower temperature settings.
