One of the best ways to prevent burning your eyes is to cool the onions before cutting.

Any type of molecules are slower when cold, so refrigerating the onions beforehand ensures that the irritating chemicals won’t rush up to you immediately [1]

You can also place the onions in the freezer for at least 15 to 30 minutes.


2. Place Wet Paper Towel On Chopping Board

Placing a wet towel near the chopping board recently went viral on social media platforms. The fumes from the onions will gravitate toward the wet paper towel instead of your eyes. 

Another way of using a dampened paper towel is to put it around the front of your neck and let it absorb the gasses from the onions.

3. Soak It in Water

Another trick to prevent your eyes from burning when cutting onions is to soak the onions in water for 10 to 15 minutes. In theory, water can wash off some compounds in the onions that cause you to tear up. 

“The sharper the knife, the less damage is done to the onion, and fewer irritations are released into the air as a result.”

It is also better to peel the onions and cut them in half or quarters before soaking them.

The last thing you need is to lock in the airflow in your kitchen and trap the fumes released by onions. Turning on the fan or opening the windows will sweep away the eye-irritating chemicals from cutting onions [2]

You can also stand by the porch and expose yourself to the air outside.

6. Cut Onions In Cold Water (But it Can Be Dangerous!)

If you are short on time to soak the onions, you can start cutting under running water. But it is not easy and is a little more dangerous. 

You must also remember that throwing wet onions in the frying pan while wet will cause them to sizzle and spit wildly.

7. Cut The Stem First

The way you cut onions can also be the reason for your teary eyes. Some people chop off the root first, where the highest contraction of compounds that make you cry is located. 

So, to save some tears, leave the root end on and start by cutting at least half an inch of the stem.

8. Always Use A Sharp Knife

A dull knife is more dangerous and will damage more onion cells than a sharp knife. It slows you down while cutting onions, exposing you more to the eye-irritating chemicals.

9. Burn a Match or Candle

Light a large candle near you before you start cutting onions. The flame will help disable the compounds released by the onion that makes you cry while chopping. 

Some people would also go to a steady and safe place near a gas stove to slice their onions. However, don’t forget to turn off the stove after you’re finished.

10.  Use Food Chopper

Although you will have less control when using a food chopper, it is still a good alternative if you aim for smaller pieces of onion.

It may result in uneven chunks, but you won’t cry as much as when chopping by hand.

Use a food chopper if you need to cut a few pieces of onion.

How Do You Get Rid of an Onion Burn in Your Eye?

You can get rid of an onion burn by rinsing your eyes with clean and cool water. But don’t forget to wash your hands thoroughly after cutting onions before touching your eyes because it may lead to more irritation. 

You should distance yourself from the sliced onion and press a cool compress over your eyes to soothe the irritation.
