Sometimes cutting an onion feels like a full emotional event. One minute you’re cooking dinner, the next you’re wiping tears like you just watched a sad movie. But here’s the truth: it’s not you—it’s chemistry. Let’s break down why onions make you cry and how to stop it so you can cook without the drama.
Why Cutting Onions Makes You Cry (And How to Stop It)
Of course they do unless you’re wearing Onion Goggles, as we do in our house. I’m hoping these cartoons will add a little humor to some everyday cooking situations you may have found yourself in.
Fast Answer: Why Cutting Onions Makes You Cry
- Onions release a sulfur gas when cut.
- This gas reacts with moisture in your eyes and forms a mild acid.
- Your eyes produce tears to wash it away.
- Use a sharp knife and chill the onion to reduce the effect.
Start Here: Stop Crying, Start Cooking
- Watch the quick video below first (fastest way to learn)
- Use a sharp knife to reduce onion damage
- Chill onions before cutting to slow the chemical reaction
- Cut efficiently—less time, fewer tears
What Most Cooks Get Wrong
- Using a dull knife (creates more tear-inducing gas)
- Cutting too slowly (longer exposure = more irritation)
- Ignoring airflow (gas lingers around your face)
- Overthinking “tricks” that don’t work
Quick Fixes to Stop Onion Tears
- Chill the onion for 30–60 minutes
- Use your sharpest knife
- Cut near a vent or fan
- Leave the root end intact as long as possible
