How to Peel an Onion Quickly

Try this method to cut and peel any sized onion in seconds!

Steps

Cut an onion in half vertically.
Place the two halves "cut side down" on the cutting board.
Cut off the unusable portions at the top and bottom of each half.
Peel back the top layer of each onion half. Your onion is now completely peeled!
Rinse the onion halves under cold water to remove any peel residue. Rinsing also reduces the amount of residue that causes your eyes to water when handling onions.
When an onion is halved, it is much easier to cut into thin slices.
Turn your cutting board ninety degrees after slicing, and you can easily dice your onion as well.

If you leave one of the ends attached from the beginning, it is much easier to dice. For slicing however, it is best to remove both ends. Don't forget to remove the end when you are finished slicing.
If you don't want to cut onion in halves, make a single shallow cut from top to bottom, just enough to slide the knife tip in and lift off the topmost layer to peel it off.

Always use care when using kitchen knives to avoid cutting yourself.
Always wash your cutting board when switching between cutting meat, poultry or fish and cutting vegetables to avoid cross-contamination of bacteria from one type of food to another.
Use a non-serrated knife: a serrated knife will twist in the onion as it cuts, and create uneven slices, and if you're not careful, injure you!
Washing your hands along with the stainless steel knife after slicing an onion (or garlic) will remove the scent from your fingers.
