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.

4. Dehydrate at 95°F for 4-8 hours

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

Ways to Use Dehydrated Wild Onion Grass

  • In small pieces, wild onion grass can replace chives. It is a little more fibrous and grass tasting than the milder flavor of chives, but it’s an interesting spicier taste to add to many meals.
  • Add to ramen or other Asian dishes for a twist on green onions.

How to Powder Wild Onion Grass

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.

2. Pulse until most of the fibrous grass has been ground

3. Begin to run full power to grind until powder is complete.

4. Put back into the dehydrator at 95F for 1-2 hrs. to fully dry powder.

How to Use Wild Onion Grass Powder

  • Use as a substitute for onion powder. It has a brighter, spicier onion flavor
  • Use to make homemade ranch dressing dry mix

SAFETY NOTE: As with all vegetables you grow at home, please make sure you aren’t foraging from an area that has been treated with harmful pesticides.
