I don’t have a green thumb, so being able to regrow green onions from scraps is about as grow-your-own as I get. I’ve always admired those that have the talent to grow their own food. It’s such an important frugal skill, that unfortunately, I’m incapable of mastering. So having an ever-growing supply of green onions that I had a hand in growing is a pretty big win for me.
How to Regrow Green Onions from Scraps
- Save the bottom white portion of the onion when you are cooking with green onions. I usually leave a bit of the green still attached, since I’m convinced this speeds up the regrowing process a smidge.
- Rinse off the roots and place the green onions in a cup of cold water.
- They shouldn’t be fully submerged in the water – just enough to cover most of the white portion of the root.
- Change the water out every two to three days.
How to Avoid Sliminess
The slimy texture is what caused me to stop doing this a few years ago. It was such a shame since I was enjoying my endless supply of green onions.
What I do now to combat sliminess is rinse the roots under cold water every two to three days and ensure that the water doesn’t touch the green part of the onion. This has worked wonderfully and I haven’t had a texture problem since.
How Long Do They Take to Grow?
The tallest green onions you see in this photo have been growing for about nine days. As you can see, they are sky high and I struggled to fit them into the photo. You will have perfectly usable green onions within five to six days. You can use them a bit sooner depending on how quickly yours are growing.
Have you ever used this method to regrow green onions? It is so simple even I can do it! I’m the girl that managed to kill tomatoes, cucumbers and strawberries all in one shot, so I mean it when I say anyone can do this.
