Want to learn How to Cut Onions Without Crying? You’ve come to the right place.
Honestly, who likes cutting onions?
No one. The answer is no one. Ever.
For the longest time, I couldn’t figure out why a vegetable that shows up in almost every recipe was out here making people cry.
Like… is this revenge for chopping it up?
But after doing a little digging, I finally learned why onions make us cry—and more importantly, I found out how to cut them without crying.
Game. Changer.
Seriously, my life in the kitchen will never be the same again. So let’s dive into the tips that’ll save your eyes (and your sanity).
Why Do Onions Make Us Cry?
Ever wonder why chopping onions turns into a teary mess? It’s not just you—it happens to all of us!
Here’s the deal: when you cut into an onion, you break open its cells.
That releases some sulfur compounds, and when those mix with enzymes inside the onion, they create a gas with a fancy name: syn-propanethial-S-oxide.
That gas floats up and hits your eyes, and when it mixes with the water in your eyes, it turns into a mild acid—yikes!
Your eyes don’t like that one bit, so they start tearing up to protect themselves and flush it out.
That’s why you feel like you just watched the end of a sad movie while prepping dinner.
How to Cut Onions Without Crying
Luckily, there are a bunch of little tricks you can try to keep the tears at bay:
1. Chill the Onion First
Pop the onion in the fridge for about 30 minutes before cutting it.
The cold slows down those tear-triggering chemical reactions. It’s a super easy fix that really helps!
2. Cut It Under Running Water
Chop your onion under a gentle stream of water.
The water helps wash away the irritating gas before it reaches your eyes.
3. Microwave It
Give the onion a quick zap in the microwave for 15 seconds.
The heat messes with the enzymes and makes the gas less intense when you cut it.
4. Place a Wet Paper Towel Nearby
Lay a damp towel or tissue near your cutting board.
It can actually help soak up some of the onion fumes before they make it to your face.
5. Keep the Stem End Intact
Cut the onion from the top and leave the root (stem) part for last.
That’s where most of the irritants hang out, so this slows down the eye-burning gas release.
6. Freeze It Briefly
Toss the onion in the freezer for about 10–15 minutes before chopping.
Like chilling, it slows down the chemical reaction. Just be aware the texture might get a little mushy if it stays in too long.
7. Breathe Through Your Mouth
Sounds weird, but breathing through your mouth instead of your nose keeps more of the gas from reaching your eyes.
8. Chew Gum or Bread
Yep, chewing gum or even a piece of bread while chopping can help!
It keeps your mouth busy (so you’re breathing through it), and some people swear it distracts your senses just enough to make a difference.
9. Use Good Cutting Techniques
Cut efficiently. Slice the onion in half first, then peel and chop.
The less time your eyes are exposed, the better.
10. Cut Near a Flame
If it’s safe to do so, light a candle or use the stove flame.
The flame can help burn off some of the onion gases before they float into your eyes.
11. Ventilate the Room
This one’s kind of obvious, but don’t forget to open a window or turn on a fan.
More airflow = fewer fumes sticking around.
12. Wear Goggles
No joke—swim goggles or kitchen-safe goggles can be a game changer.
If you’ve got a pair, you’ll be chopping tear-free in no time.
13. Use a Sharp Knife
A dull knife crushes the onion and releases more gas.
A sharp one slices clean and keeps those cells intact longer, which means less crying for you.
Which Onions Make You Cry the Most?
Not all onions are equally evil when it comes to tears. Some are definitely worse than others.
- Yellow onions: These guys are the biggest culprits. Lots of sulfur = lots of tears.
- White onions: Milder flavor, fewer tears.
- Sweet onions (like Vidalia or Walla Walla): They have the least sulfur, so they’re the most tear-friendly of the bunch.
That said, everyone’s eyes are different, so what makes one person cry like crazy might not bother someone else at all.
