Watch How to Cut an Onion Properly

How To Cut An Onion: Step by Step

Step 1: Cut the Onion Bulb in Half

Before you begin, be sure to find a nice, fresh onion. Look for one that’s firm, with no signs of sprouting or soft spots. Then, stand the onion upright and cut it in half vertically, from stem to root. Cutting the onion in half will make it much easier to peel and dice later on.

Step 2: Trim the End of the Onion

Now, lay one half of the onion on a cutting board and use a sharp knife to slice off the top stem end. You can discard this end or save it for stock. Leave the root intact – do NOT cut the roots off!

Step 3: Remove the Onion Skin

Now it’s time to peel the onion. If you can’t get a grip on it, try gently scoring the skin lengthwise, making sure not to cut too deeply into the onion itself. Once you’ve made several shallow cuts, use your fingers to peel away the papery skin toward the root, revealing the fresh onion layers beneath.

Step 4: Cut the Onion Down the Middle

Once the onion is peeled, cut the onion once down the middle, parallel to your cutting board. Remember not to slice all the way through the root end! Keeping that end intact will ensure that the onion stays together for a better cut!

Pro Tip: Make more cuts for a mince or finer dice!

Step 5: Cut the Onion Lengthwise

Now, hold the onion firmly and make vertical cuts, creating even slices from the top, close to the root. Make sure not to cut the root.

It’s also important to use a proper cutting technique! Be sure to keep your fingers safely tucked away from the blade when you cut the onion.

Step 6: Dice the Onion Crosswise

Now that you have evenly sliced onion strips, it’s time to dice them into smaller pieces. Hold the onion with your fingers curled and the blade against your knuckles to make safe horizontal cuts across the length of the onion. Remember, the size of your dice can vary depending on your recipe!

Pro Tip: Aim for uniformity to ensure even cooking.

And there you have it—six simple steps for the best way to cut an onion! Now all you need is a tasty recipe to try it out with, and the good news is we have a ton of Spice World favorites for you to choose from!
