How to Chop an Onion

Cooking Techniques

Preparing your ingredients can often take you longer than the cooking process itself – onions in particular are very fiddly to chop. Here is a step-by-step guide to help you to cut onions up finely and evenly:

  1. Make sure you have the right equipment. You should make sure you use a sharp serrated knife and have a good quality chopping board.
  2. Start by peeling the onion, slicing off the top and cutting in half down the middle through the root.
  3. Place the onion with the flat cut side face down on the chopping board. Slice finely lengthways from one edge to the other.
  4. Slice from the root downwards 4 to 5 times, leaving about 1cm of the onion still attached to the root to keep the pieces in place whilst you’re cutting it.
  5. Finish off the process by slicing from top to bottom. The onion may feel like it’s starting to fall apart slightly despite having the root in place, so you’ll need to hold it together carefully. Once you get to the end you should just have the root left.

By following these instructions, you’ll be able to slice an onion into equally-sized pieces which will cook evenly. It may take a little while to perfect the method but it will be worthwhile for your cooking.
