Kitchen Tip – How to Regrow Green Onions

green onions

Green onions are used in lots of Asian recipes, and they are actually super simple to regrow on your windowsill from the trimmings that you would normally compost.

I cut the green part off the green onions so that there’s about  1.5 – 2 inches of the white part attached to the roots.  Then put the green onion roots in a little jar (old spice jars seem to work well for this) and add about 1.5 inches of cool water into the jar. I put a little piece of folded paper towel under the jar when I put it in the windowsill so that no watermarks stain the wood.

Replace the water everyday (that way the water doesn’t get slimy as quickly). I’ve been able to successfully regrow a trimmed green onion root about 2-3 times.  After that, they get a little too slimy around the roots and it’s time to compost them and wash out the jar.

The picture shows about a week of growth, and you can trim off what you need to add to dishes.

You can also plant the trimmed green onion roots in some soil, and they should regrow a few more times than if they were simply regrown in water.

I hope that this tip helps you save a little money! Let me know how this trick works for you. What would you make with your regrown green onions?
