How to dice an onion

Visit waitrose.com/howto for a video clip of this and other easy-to-follow culinary techniques.

Try freezing onions for 20 minutes before chopping them, to stop your eyes from watering. Once cut, an onion should be wrapped, refrigerated and used within 4 days.


Step 1

Cut the onion in half, slicing downwards through the root, then peel.


Step 2

Cut 5-6 vertical slices into each half, leaving the root intact.


Step 3

Lay the onion half flat, slicing horizontally and keeping the root intact.


Step 4

Slice downwards across these cuts to dice.
