Peel Away the Myths

Before we delve into the techniques, let’s address the age-old myths surrounding onion cutting and tears. Onions contain sulfur compounds and an enzyme called synthase. When you cut into an onion, these two components react and release a chemical compound called syn-propanethial-s-oxide. This compound irritates the glands in your eyes, resulting in tears. While many methods claim to prevent tears, such as cutting with a sharp knife or avoiding the root end, the only foolproof solution for some is wearing contact lenses.

The Classic Culinary School Peel

Let’s start with the classic method taught in culinary school. Begin by using a paring knife to remove the bottom and peel away the skin up to the root end, eliminating any dry skin. Leave the root intact but trim any unsightly ends. This technique ensures that the onion holds together during slicing and chopping. However, it requires the use of two knives, which can be a bit cumbersome.

A Quicker Approach

Now, let’s introduce a method I learned from a seasoned cook named Alberto. Although initially skeptical of his advice, I soon realized that learning from those who perform a task regularly can be invaluable. To begin, cut off both ends of the onion and peel away the first layer. While some may argue that this approach results in a small waste, I assure you it’s worth it. This method saves time and works well for all cuts except when making onion rings or grating.

It’s Time to Cut and Slice

Once your onion is peeled, it’s time to explore the various cutting techniques. Slicing an onion offers several options, including full rings, half rings, thick slices, thin slices, and julienne cuts. Julienne cuts are perfect when you want the onions to retain their shape, such as in a French onion soup. Follow the natural lines on the onion, allowing your knife to guide the slices, and create beautiful julienne cuts.

Mastering Dicing Techniques

Dicing onions is essential for creating finely chopped pieces of uniform size. We’ll explore fine chops, small dice, and medium dice. The classic culinary school method involves keeping the root end intact and making precise cuts. However, the quicker method I prefer involves cutting the onion along its natural separations, resulting in evenly diced pieces. Whether you opt for small or medium dice, these techniques will add texture and flavor to your culinary creations.

Grating Made Easy

Grating onions can be a game-changer for dishes like meatballs, meatloaf, or even potato pancakes. A box grater is a versatile tool that every kitchen should have. Instead of using sheer muscle strength to grate, try a different approach. Lay the grater on its side and hold it together with your other hand. Then, use your body weight to push the whole onion across the grater, making the process quicker, more efficient, and less messy.

Final Tips and Precautions

Before we conclude, a word of caution. Cutting onions finely will release more chemicals, resulting in increased tears. To prevent excessive crying, open a window or turn on a fan to improve ventilation. You might also want to step out of the kitchen temporarily. And remember, onions are best enjoyed cooked, not raw!


Q: Are there any tricks to minimize tears when cutting onions?
A: While various methods claim to reduce tears, wearing contact lenses has been proven effective for many individuals.

Q: Can I use a food processor to cut onions?
A: Absolutely! A food processor can save time and effort, especially when handling large quantities of onions.

Q: What can I do with finely chopped onions?
A: Finely chopped onions are great as garnishes or for adding flavor to dishes like caviar service or stuffings.


Congratulations! You are now equipped with the knowledge and skills to confidently cut onions like a pro. Whether you’re mastering slicing, dicing, or grating, these techniques will elevate your culinary creations to new heights.
