How to dice an onion – the easy way.

This trick will make dicing onions quick and so very simple.

Onions get all the grief. They stink up our kitchens and they sting our eyes and make us cry. Yet, onions are in so many recipes, all kinds of dishes: soups, sauces, salads, fried, broiled, and baked bringing their own special flavor to your recipe. It’s hard to cook without this veggie!

I even know someone who eats onions raw! With salt! Seriously. He told me the other day that when he was a small kid, his mother told him that onions were brain food. He’s been eating them raw ever since. He IS smart, but I don’t think onions are the reason!

There are so many different varieties of onion, each with their own unique color, aroma, and flavor. I’m going to focus on the full round varieties. The most common type of these is the “yellow” onion. This is the full-flavor variety that you’ll find many recipe authors call out in all kinds of preparations. You’ll find “white” onions in Mexican dishes. They give off a sweeter flavor when sautéed with proteins like chicken, beef, and pork. Red onions are generally milder in flavor and are awesome raw, so you find them in lots of salads and some soups.

With these three most common varieties, you’ll often be asked to dice. I’ve tried all kinds of ways to dice “full round” onions. Have you ever sliced an onion then restacked the cuts to slice again? You know how clumsy that is, right? Well, there’s only one way that really beats all of them. I’ve been using this method for years – it’s one of the best lessons I learned from a chef friend. It’s the method I’m going to show you now. Check out my video so that you also see how it’s done in seven easy steps:

  1. Cut ½” from the stem end – this is the top of the onion where the stalk grows.
  2. Turn the onion around and cut into the root about half way. Don’t cut the root off completely. You’ll see why in a minute.
  3. Lay the onion on the stem end and cut the onion in half, vertically through the top to the root end. Then peel the onion. Remove the outer most ‘paper’ layer and one more ‘onion’ layer.
  4. Lay one half of the onion on the flat side and make vertical cuts. Keep your fingers curled under to protect them and be careful to NOT cut all the way through the root end.
  5. With your hand flat on top of the onion (keeping your fingers far from the knife) make two (or more) horizontal cuts. Again, be careful to not cut through the root end because we need the root to hold the onion layers together for us.
  6. Slice across your previous cuts, all the way through, till you reach the root end. Now you have a diced onion!
  7. The closer together your horizontal cuts and vertical cuts are the smaller your dice will be. This method can also be used if you need larger pieces for skewers – just make your cuts about ½” apart and the onion pieces will separate into perfect larger pieces.

One last little tip: use your knife to chop your diced onion on the board if you want a finer dice.

Enjoy!
