How to chop onions?

So, do you like chopping onions? Most people I know don’t, because not only can it be a hassle, cutting onions can also make you cry. But here’s the thing, if you know how to properly cut an onion, it’s easy, safe, and relatively tear-free. Of all the cooking skills I’ve learned over the years, this is the one skill that has made the most difference in terms of making cooking enjoyable.

I don’t worry about chopping off a fingertip, and rarely do I cry over onions (other things yes, onions no).

So what’s the trick? Everyone will tell you that it helps to use a sharp knife. Well, a sharp knife will make cutting anything easier. But the reality of a home kitchen is that our knives aren’t always as sharp as we would like them to be. Which is why it’s even more important to learn how to cut an onion properly—stabilizing the onion as much as you can throughout the cutting process, and holding the onion in a way that protects your fingers.

The trick to avoiding tears is to keep your exposure to the cut sides of the onion to a minimum. When an onion is cut, fumes are released that irritate the eyes. So when you cut an onion in half, keep the cut sides down on the cutting board. When you first start to make cuts into the onion, keep the onion together so you don’t expose the cuts. When you make the final cuts to the onion, work fast and move the chopped onions into a bowl, away from your eyes, quickly.

I made short (about a minute long) video of how I cut onions to demonstrate, and the more detailed instructions follow. Hope this helps any of you who struggle with cutting onions!
