Watch this quick video to learn how to cut onions without crying.

Why do onions make us cry?

When you slice into an onion, it releases sulfur compounds. These compounds mix with the natural moisture in your eyes, creating a mild form of sulfuric acid. That’s what causes the burning and tears.

Two simple tricks to prevent onion tears

1. Chill the onions: Place onions in the fridge for 30 minutes before cutting. The cold slows down the release of tear-inducing chemicals.
2. Cut under running water: The water helps wash away the sulfur compounds before they reach your eyes.

Extra tips for tear-free chopping

• Use a very sharp knife — it causes less damage to onion cells, reducing the release of irritants.
• Cut near a fan or open window to improve ventilation.
• Try wearing kitchen-safe goggles if you’re especially sensitive.
• Always cut off the root last — it contains the highest concentration of compounds.

Final thought: With a chilled onion, running water, and a sharp knife, you can enjoy cooking without tears. Simple habits make a big difference in your kitchen experience.
