How to Cut an Onion Without Crying: 10 Proven Methods


In this guide, we’ll dive deep into why onions make us cry and, more importantly, How to Cut an Onion Without Crying.


Cutting onions can be one of the most dreaded kitchen tasks.

Almost everyone who’s cooked at least once has experienced the watery eyes and stinging sensation that comes from slicing into an onion.

It doesn’t matter how much you love cooking; when tears start streaming down your face, the fun quickly fades.

However, if you’ve been searching for a solution on how to cut an onion without crying, you’ve come to the right place.

With a range of effective techniques and tips, you’ll learn how to cut an onion without crying and finally enjoy tear-free cooking.


Why Do Onions Make You Cry?


To understand how to cut an onion without crying, it’s important to know why onions make you cry in the first place.

Onions contain sulfur compounds, and when you cut into them, you break open the onion’s cells.

This action releases a gas called syn-Propanethial-S-oxide, which wafts through the air and eventually reaches your eyes.

When it comes into contact with the moisture in your eyes, it forms a mild form of sulfuric acid, which irritates your tear ducts.

The natural response of your body is to produce tears to wash away the irritant.


Interestingly, not all onions are equal when it comes to tear production. Some onions, like yellow or red onions, contain more sulfur than others, making them more likely to cause tears.

On the other hand, sweeter onions, such as Vidalia onions, tend to have lower sulfur levels and are less likely to make you cry.

But even if you’re dealing with a tear-inducing variety, there are several methods that can help you cut an onion without crying.

Now that you know why onions make you cry, let’s explore some of the most effective ways to cut an onion without crying.

Whether you prefer high-tech solutions or more traditional methods, there’s a trick for everyone.

Use a Sharp Knife


One of the easiest and most effective ways to cut an onion without crying is by using a sharp knife. A dull knife crushes the onion’s cells more forcefully, releasing more of the gas that causes tears.

A sharp knife, on the other hand, makes cleaner cuts and causes less cell damage, reducing the amount of gas released.


To keep your knife sharp, use a knife sharpener regularly or have your knives professionally sharpened.

Not only will this help you cut an onion without crying, but it will also make all your chopping tasks easier and safer.

Chill the Onion Before Cutting


Chilling your onion in the fridge or freezer for a short period before cutting can significantly reduce the amount of gas released.

Cold temperatures slow down the enzyme activity that produces the irritating gas, making it easier to cut an onion without crying.

Simply place the onion in the fridge for about 30 minutes or in the freezer for 10 minutes before cutting.


While this method is highly effective, be mindful not to freeze the onion for too long.

Freezing can change the texture of the onion, which may not be ideal for certain dishes, especially if you’re using raw onion.

Cut the Onion Under Running Water


Another method on how to cut an onion without crying involves cutting the onion under cold running water.

The water helps to wash away the sulfur compounds before they can reach your eyes.

This method can be a little tricky, as you’ll need to manage both the water and the onion without making a mess.

However, it’s worth a try if you’re dealing with particularly potent onions.


Alternatively, you can place a bowl of water next to your cutting board. The water will still absorb some of the gas, reducing its effect on your eyes.

Use a Ventilator or Fan


If you’re in a kitchen with good airflow, turn on the fan or a kitchen ventilator to help blow the irritating gas away from your face.

A simple fan directed towards the onion or the window can be surprisingly effective at keeping the gas away from your eyes.

This is an easy and hands-free way how to cut an onion without crying.


For best results, place the fan near the onion and make sure the airflow is directed away from your face.

You can also try opening windows to create better ventilation in the room.

Cut Near an Open Window or Outside


Fresh air can significantly dilute the concentration of the gas released by onions, which can help you cut an onion without crying.

If you have an open window in your kitchen, set up your cutting board nearby.

The natural breeze will disperse the irritating gas before it reaches your eyes.


If the weather permits, you could even try cutting onions outside.

Outdoors, the gas dissipates quickly, so you’re less likely to cry while slicing.

Wear Goggles or Glasses


For a more high-tech solution, wearing goggles can prevent the gas from reaching your eyes altogether.

Kitchen safety goggles or even swimming goggles create a barrier that blocks the gas, allowing you to cut an onion without crying.

This is one of the most foolproof methods, especially if you’re sensitive to the gas.


If you don’t have goggles handy, you can try wearing regular eyeglasses.

While they won’t create a complete seal like goggles, they can still provide some protection.

Soak the Onion in Water


Soaking the onion in water for a few minutes before cutting can help reduce the amount of gas released.

Simply peel the onion and place it in a bowl of cold water for about 10 minutes.

The water absorbs some of the sulfur compounds, making it easier how to cut an onion without crying.


This method works well for most recipes, although it might slightly alter the flavor of raw onions used in salads.

If you’re cooking the onions, the slight flavor change won’t be noticeable.

Use Lemon Juice on Your Knife


Rubbing a little lemon juice on your knife before cutting the onion can help neutralize the gas released by the onion.

The acid in the lemon interacts with the sulfur compounds, reducing their potency and helping you cut an onion without crying.


While this method might seem a bit unusual, it’s worth trying if other techniques haven’t worked for you.

Plus, the lemon juice won’t affect the flavor of the onion, so it’s a win-win.

Cut the Root End Last


The root end of the onion contains the highest concentration of sulfur compounds, which means cutting it first will release more gas.

To avoid this, start by cutting the top of the onion and save the root end for last.

By cutting the root end last, you’ll minimize the amount of gas released, helping you how to cut an onion without crying.


When handling the root, be gentle to avoid crushing it, as this can release more of the tear-inducing gas.

Light a Candle While Cutting


It might sound a bit unconventional, but lighting a candle while cutting onions can actually help.

The flame from the candle attracts the sulfur compounds, reducing the amount that reaches your eyes.

While this method may not be as effective as some of the others, it’s worth a try if you want how to cut an onion without crying.


This method works best in small kitchens where the gas is more concentrated, but it can also be helpful in larger spaces.


Techniques for Specific Onion Cuts


Different onion cuts require different techniques to ensure you how to cut an onion without crying.


Slicing for Salads


When slicing onions for raw salads, it’s essential to minimize the gas as much as possible since raw onions release more gas.

Chilling the onion or cutting it under running water works well for this purpose.


Dicing for Soups and Stews


If you’re dicing onions for soups or stews, you may find that wearing goggles or using a fan helps you finish the task tear-free.

Since the onions will be cooked, you won’t need to worry about the flavor being affected by water or chilling.


Chopping for Sauces


For sauces, you can use any method that helps you work quickly and efficiently.

A sharp knife and a fan are usually enough to prevent tears.
