Chopping onions without crying is definitely one of the great kitchen challenges 😅—but luckily, there are a bunch of tricks that actually work! Here are some tried-and-true methods:
🔪 1. Chill the Onion First
-
Pop the onion in the fridge or freezer for 10–15 minutes before chopping. Cold slows down the release of the irritating gas (syn-Propanethial-S-oxide) that makes you tear up.
💧 2. Use a Sharp Knife
-
A sharp knife causes less cell damage, meaning fewer irritants are released into the air.
-
Dull knives = more crushing = more crying.
🌬️ 3. Cut Near a Fan or Vent
-
Turn on a kitchen fan or cut near an open window so the onion gas blows away from your face.
💦 4. Cut Underwater (or Rinse Often)
-
Some people chop onions under running water or in a bowl of water to prevent the gas from reaching their eyes.
-
Or rinse the onion after peeling and slicing in half.
😎 5. Wear Goggles
-
Yep, swimming goggles or onion goggles actually work.
-
They form a seal around your eyes, blocking the irritating gas.
🍞 6. Hold a Piece of Bread in Your Mouth
-
Sounds weird, but it’s an old trick! The idea is that the bread absorbs some of the onion fumes before they get to your eyes.
🕯️ 7. Light a Candle Nearby
-
The flame may help burn off some of the sulfur compounds in the air, reducing eye irritation.
🧅 8. Cut Off the Root Last
-
The root end has the highest concentration of the eye-irritating enzyme.
-
Leave it intact while chopping, and cut it off last to reduce exposure.
