Cooking 101: How to Chop an Onion

There are lots of methods out there for chopping up onions. I think this is the easiest way.

What you need: Onion, Cutting Board, Knife.


First, cut both ends off your onion.


Set your onion on end, and cut it in half.


Peel off the outer layer, removing the skin.


Here’s the great thing about onions. Onions have layers. That means they like to make your job easy, if you know how to take advantage of them.


Lay one onion half down on the board, and using your knife, cut all the way through the onion, but not all the way across. Leave about 1/4-1/2 of an inch uncut on one side. This will hold your onion together and making the cutting easier.


Now taking advantage of the layers, make additional cuts, from the outside towards the center, from the middle cut out to both ends, like the rays of the sun.


By leaving the very end uncut, all these layers stay nice and still for you.


Now starting from the cut end, start slicing your onion. As you cut the onion into slices, the onion naturally comes apart by layers, as though it had been cut.


Slice until you reach the uncut end. You will be left with a half-circle slice.


Lay it down, and simply cut slices from one end to the other.


Repeat the process with the other half of the onion.


You are left with a perfectly chopped onion.


Depending on how large or small you want your onion pieces, simply adjust how closely you make the two sets of slices. Close together will give you smaller pieces, farther apart will give you larger chunks.

It’s that easy.

      I haven't tried it, but I think if you freeze the onion, it will turn to mush when it thaws. Honestly the only thing that has worked for me, is the fact that I wear contacts. When I cut onions in my glasses, my eyes burn. When I am wearing contacts, they don't. I have *heard* that holding a toothpick in your mouth while you cut actually helps (have heard it repeatedly) but I have never tried it.
