TIPS & TRICKS FOR YOUR KITCHEN 🧅
HOW TO DICE AN ONION
It’s one of the most basic kitchen skills, but getting it right makes cooking quicker, easier and far more consistent.
Here’s a simple way to dice an onion without making it complicated.
Step 1 — Remove the top
Slice off the pointed stem end of the onion, but leave the root end attached.
Step 2 — Cut it in half
Slice the onion lengthways straight through the root. Peel away the papery skin and any tough outer layer.
Step 3 — Keep the root intact
Place one half flat-side down on your chopping board. The root helps hold all of the onion layers together while you cut.
Step 4 — Make your first cuts
Starting at the front of the onion, make cuts towards the root, stopping just before you reach it.
Rather than cutting perfectly straight all the way across, slightly angle your knife to follow the natural curve of the onion. This gives you a more even dice.
Step 5 — Choose your size
This is where you control the finished result.
Cuts closer together = finer dice.
Cuts further apart = larger, chunkier dice.
Step 6 — Cut across the onion
Turn the onion and slice crossways through your first cuts. The onion will naturally fall into an even dice.
Step 7 — Finish at the root
Keep cutting until you reach the root, then remove and discard it.
That’s it. No complicated technique and no unnecessary cuts.
One extra tip: you generally don't need the old-school horizontal cuts through the side of the onion. The onion already has natural horizontal layers, so following its shape with your first cuts is quicker, safer and does the job.
