There is a world of forageable goods in many a backyard if only we know what to look for!

Wild Onion Grass - which grows like mad in our yard is one that I began exploring with this spring!

The entire plant is edible, with an onion-like bulb and a green shoot. The onion can be sliced and dehydrated in the same way - and used in much the same way you'd use spring onion or onions to flavor with, etc.

We're only working with the greens now as our yard makes it hard to get out the bulbs, but here are the simple instructions!

How to Dehydrate Wild Onion Grass

1. Harvest grass from the bulb.

2. Wash in warm water to remove any residue.

3. Snip grass in manageable lengths.

While I did 3 inches in this shot, 1-2 inches is preferable for long-term storage. For powdering, even smaller will work. These do not shrink the way that chives do.

You're looking for a crispy, dry green. I use an Excalibur Dehydrator, but any dehydrator will work as long as it has a temperature guide. If your machine is a one temperature machine, it's best to let these air dry.

5. Condition

Yes, even condition your greens and herbs before putting away for storage.

6. Store in an airtight container

1. Place wild onion grass into a blender or bullet blender.

I find that a larger blender works best on this than a small coffee grinder size.
