Learning how to slice an onion is a basic cooking skill that all home chefs should know how to master.
To chop an onion, you just need your onion and a sharp chef’s knife.
Many many meals start with a pile of freshly sliced onion on your cutting board. This article will teach you how to dice and how to slice an onion.
Step 1: Find the Root End & Slice Down the Center
As you can see from the pictures, I sliced the onion slightly off-center. I did this to avoid slicing directly through the root end. This will help avoid the onion bleeding, which will also help avoid crying when cutting the onion.
After cutting the onion through the center, you are set up for the next steps.
Step 2: Peel off the Skin & Chop off the Stem
After slicing the onion in half, chop off the stem and discard. Leave the root end attached. It’s best to leave it attached for two reasons:
- It will keep the onion from falling apart.
- It will prevent the onion from bleeding which will prevent you from crying.
Step 3: To Dice, Make Vertical Cuts
If your goal is to have a diced onion, first make cuts towards the root and then make perpendicular cuts at a right angle. This will give you a perfect diced onion.
Step 4: To Slice, Make Vertical Cuts
When making slices of onion, start with the stem end that is now cut off. Begin making slices as thick or thin as you’d like them.
Slicing this way is an easy way to make slices, as they will automatically come apart in your hands.
After you have your neat onion slices, you are ready to get cooking!
