As we continue with knife skills, here is a photo tutorial on how to dice an onion. I did swipe some of the pics from the how to slice an onion tutorial, because why reinvent the wheel? It will take practice to pick up speed and unless you’re making an exceedingly fancy dish, a perfectly even dice isn’t critical. As long as the pieces are roughly the same size they will be fine for most applications. Generally the sides of a diced onion are 1/4″ or so. This will determine whether two or three planks* need to be cut.
*We’ll get there, don’t worry.
The right tools help. For this chore I prefer a chef knife1, but a utility knife
1 can be used in a pinch. Ready?
Grab the onion, a knife, and a cutting board.
Slice the tip off of the onion.
Slice the onion in half, through the root. Use the tips of your fingers to steady the onion.
Peel the top most layer from the onion. If the onion is bruised, sometimes a couple of layers will need to be removed.
Make the first plank cut. Cut from the tip toward the root about 1/4″ above the cutting board. Do not cut all the way through the root, or the onion will be difficult to keep together.
Make a second plank cut 1/4″ above the first and add a third, if the onion is large.
Grip the onion with the tips of your fingers, if the knife slips, it will most likely come in contact with fingernails rather than flesh. Slice the onion with even cuts, again being careful to not cut all the way through the root.
Turn the onion, adjust your grip to hold the slices together by gently squeezing with the tip of the pinky and thumb. Begin cutting perpendicular -at a right angle- to the slices made in the previous step.
As these cross-cuts are made, the onion will fall away into an even dice.

1These are an affiliate link to the knives I use most frequently. They are of decent quality, but I don’t feel the need to obsess over their care as I would if I had the knives I daydream about. Even without care obsession, this set has lasted ten years and the handles and blades are still in good shape, despite my abuse.










i think my way is quicker...i use a serrated steak knife and proceed as you do in your tutorial except i skip the part where you cut "planks"....the onion is circular in pattern which makes cutting the planks a waste of time. if you just make the perpendicular cuts then slice across you will get the same results plus as you lightly squeeze that onion you won't have layers slipping out. the serrated knife has more teeth so to speak so there is very little slippage there either. of course, each to their own method as onion dicing, chopping, slicing etc.. can be deeply personal. i have a cuisinart too and i have'nt used it much unless i have a really big recipe and a really lot of stuff to chop, slice, and dice!
