Hack #1: Chill Out with the Freezer
Onions release their tear-inducing gases when you cut into them. The cooler they are, the less active those sulfuric compounds become. That means putting your onion in the freezer for 10–15 minutes before chopping can seriously reduce the sting!

Hack #2: Slice It in Its Sleep
Another sneaky method is to chop the onion while it's submerged in cold water. This might sound odd, but the sulfuric compounds dissolve into the water instead of wafting up into your eyes. Just make sure to drain and pat dry afterward if you're cooking them later.
Method | Tear-Free? | Prep Time | Equipment Needed |
---|---|---|---|
Slicing in Water | ✅ Yes | 5–10 mins | Bowl + Water |
Freezer Chill | ✅ Yes | 15 mins | Freezer |
Sharp Knife Only | ❌ No | 5 mins | Kitchen knife |

Hack #3: Use a Food Processor (Like a Boss)
For those who want speed and consistency, a food processor is your best friend. Simply peel and quarter the onion, toss it in the processor, and pulse until it’s finely chopped. Bonus: You get uniform pieces every time!

Hack #4: Soak Your Slices
If raw onions are too strong for your recipe (like salads or salsas), soak your minced slices in cold water for 10–15 minutes. This removes some of the sharp bite and mellows the flavor beautifully.

Hack #5: Invest in a Tears-Free Onion Chopper
Yes, they exist! Onion choppers are small devices that dice onions inside a sealed container. Since the fumes stay trapped inside, your eyes stay happy. Some even come with interchangeable blades for different cuts.

Storing Your Minced Onions Like a Pro
You've done all the hard work mincing those onions — now let’s make sure they last!

Storage Method | Shelf Life | Flavor Retention | Best For |
---|---|---|---|
Fridge (Airtight) | 5–7 Days | Good | Daily Cooking |
Freezer (Flash Frozen) | 6 Months | Excellent | Batch Cooking |
Canned | 1–2 Years | Moderate | Long-term storage |
