Best Way To Freeze Onions

Time to freeze onions!

chopped onionDid you know you can freeze onions?  I came upon this kitchen hack accidentally one night while cooking dinner.  After I made dinner I had half an onion left over I didn’t want to throw out, so I hurriedly chopped it up and stashed it in a Ziploc bag in the freezer.  I had no idea if it would keep or not, but it didn’t hurt to give it a shot. The next time I made dinner and needed some chopped onions, I grabbed the bag of onions from the freezer and added it straight to the pan.  The onions weren’t watery or mushy, and they cooked up like champs.

Win, win, win, winnnnning.  Too many wins?  Nah.

    I’ve been doing this for years – except after I chop the onion up, I put the pieces in a baking dish (like a brownie pan) and freeze them that way. Then, after they’re frozen (maybe 24 hours or less?) I scrape them into a ziploc bag. That way, you can use as much or as little as you’d like and they’re not frozen in a solid block.

    So good to know! I was just asking someone the other day if onions could be frozen or not!
