How to Recycle Green Onions

Every year, my husband and I enjoy watching “The Next Food Network Star”. For those of you who are not familiar with this show, 10 chefs compete in a reality show to see who will win their own show on The Food Network. Really it’s just a way to put a reality show on every station, but like true Americans, we fall victim to the trend.
A few years ago, one of the contestants (Melissa) gave a great tip (and she ended up winning). For those of you who don’t watch the show, I will share this tip with you because I think it’s so cool.

The tip: How to recycle green onions.

Next time you use a green onion, rather than throw away the tip with the root, put it in a glass of water and grow another green onion!! When I cook with green onions, I generally use the entire onion, but I found if I left about 1 inch of the white on the root, I was able to grow another onion. Here are some pictures of my onions’ developments (There are two in this cup).

Day 1


Day 2


Day 4


And so on to ……

Day 7


The bad news is, I’ve only been able to get the onion to re-grow once with each root. I tried to recycle these roots one more time, but after a week, I finally accepted they were gone. Still; that means you’ll only have to buy half as many green onions as usual.

    That is so neat! I don’t use green onions often, but I think I’m going to use some soon so I can try this!

    It’ll be a great science experiment for when I have children someday, too!

    They are amazing! if you actually plant the green onion on the ground or a pot, it will keep growing indefinetely. They are also winter hardy – they will die off and come back again every spring. I have planted them all along my vegetable beds – they protect my vegetables from rabbits – just like a natural fence!

    That is so cool! Do you have any good ideas for the green tops of leeks? Whenever I find a recipe with leeks it always says not to use the green tops. It seems like such a waste.

      I am a loyal follower of Food Network & have learned MANY things from ALL of the chefs.Therefore I can’t remember which 1 I learned this from.It was suggested that you put the leek tops in the freezer for the next time you want to make a stock.They make a passable substitution for onions.
