Preserving Green Onions

No matter how we try to use up green onions from the garden, we always end up either with too many in the fridge or overgrown, leek-sized onions taking up space in the garden. This week we did something about it.

Now that the days are longer, we hauled out our trusty solar food dryer to put it to work for the season. In addition to making delicious flax chips again, we’ve christened the solar dryer this year with our green onion harvest.

1) Chop or slice green onions into thin rounds after washing and patting dry. Keep sizes uniform and (lesson learned) separate thicker white parts from thinner green parts. They require different drying times, so isolation is a good practice here.

2) Spread the slices out on screens in a single layer. Keep some space between each piece.

3) Dry away. That’s basically it!

Our solar food dryer has 2 shelves, and most electric dehydrators have 5-9. Just make sure there is enough space between to allow air flow.

Notes: about half way through drying time (the halfway point in this case was about 7 hours) rotate trays. You’ll also see that we didn’t separate whites from greens, a mistake we won’t make again. The whites were still soft after many of the greens were dry and brittle.

In the end we left our dried onions out on the counter overnight to let them finish drying completely and acclimate to indoor humidity. Now they are ready for storage in a mason jar in the pantry.

    Where did you get your solar dryer? What’s the best-value one? Or, is it easy and cheap to build your own? Thanks for the advice.
