Onions are a major component in numerous recipes, enhancing the taste and scent of meals ranging from stir-fries to soups. But onion cutting usually has one annoying and unavoidable side effect - tears. Anyone who has ever chopped an onion knows just how frustrating this can be when your eyes begin to burn and water uncontrollably. For many home cooks, this dilemma transforms a staple type of kitchen work into an unpleasant chore.
Luckily, there are methods to cut onions without crying. With knowledge of why onions cause that stinging sensation, combined with some simple kitchen tricks, you can make cooking less painful and potentially more productive. This can help you with cooking without tears. There are several ways to ease the irritation and make it a tear-free experience, from chilling the onions first to simply using a sharp knife.
Before revealing the best ways to chop onion without tears, it’s worth understanding why this particular vegetable elicits such a powerful response. When you cut into an onion, you rupture its cells, and the sulfur compounds within them float free and, interacting with enzymes, combine to create syn-Propanethial-S-oxide. This necessary gas rises really fast and reaches your eyes, where it reacts with moisture to create a weak sulfuric acid. This causes a burning sensation that your tear glands react to by generating tears as a protective response.
How strongly this happens depends on the type of onion you are cutting. While all onions can help induce tears, some types, like red and white onions, have more sulfur in them, which makes them more irritant. In contrast, sweet onions contain much less sulfur, and they induce tears less readily. The secret to chopping onions without crying is to minimize the dispersal of these annoyance-causing compounds as much as possible.
The most effective way to stop your eyes watering when you chop onions is to cool them before you cut them. Cold temperatures inhibit the release of sulfur compounds into the air, in turn limiting the amount of irritants released into the air. Putting an onion in the refrigerator for at least 30 minutes or the freezer for 10 to 15 minutes before cutting it up can really help.
It's especially handy for those who often cook with onions and want a fast, no-fuss option. Since the onion is cold, it’s crispier and firmer and, therefore, easier to slice. Refrigerating onions also helps to keep them fresh, which is crucial for the texture and flavor of your cooking.
Cutting onions also releases sulfur gas, and the kind of knife you use affects the amount that’s expelled when you chop (more on that below). A dull knife destroys the onion’s cells instead of cutting them cleanly, increasing the release of irritating compounds. The best chef’s knife is sharp and high quality, enabling precision, speed, and minimal harm to the onion’s cell structure when creating the chop.
A great knife is the key to great meals - a good knife makes cutting an onion easy and makes your food prep better. A good knife, when properly maintained, saves some elbow grease and helps you make cuts that are regular and even, creating texture opposite your dishes that are more aesthetically pleasing.
Regularly honing your knife and using appropriate cutting techniques can help you cut onions without bawling up a storm and transform non-tear cooking from a dream into reality.
You can also chop your onions under running water, another clever trick for preventing eye irritation. The water helps carry off the sulfur compounds before they can get to your eyes, so you cry less. This only works, of course, if you’re chopping so many onions at once that you need to neutralize the irritating fumes quickly.
Cutting onions under running water may take some practice, but it prevents accidents. The onion is slippery and each time a blade cuts through the water flows a trail. For greater safety, try chopping the onion in a shallow bowl of water instead. With this technique, still less irritants are released and control over the cutting process is increased.
For anyone who cooks with onions on a regular basis and finds themselves prone to tearing, protecting eyewear can make all the difference. Safety glasses, swimming goggles or onion goggles form a barrier that prevents sulfur gas from hitting your eyes. These glasses seal off the area around your eyes so you can chop without tears.
This technique may seem far from standard practice, but it's one used by many pros in high-volume, onion-chopping-happy kitchens. The performance of protective eyewear is only as good as the fit, seal, and layout around your eyes. If you don’t own any spare onion goggles, wearing a pair of tight-fitting swimming goggles can achieve pretty much the same thing and enable you to cook without tears of frustration (due to all that lens fogging up).
Slicing onions under running water is another trick that help preventing tears, as well as soaking onions in water before cutting them. First, soaking the onion in a bowl of water for 10 to 15 minutes dilutes and neutralizes its sulfur compounds, minimizing the concentration of the fumes released when slicing.
Although this technique is particularly successful, it may remove some of the onion’s crunch. This water absorption can render the onion too soft (certainly not desirable if you're preparing a dish like a salad or a sandwich that would benefit from the crunchiness of a fresh, raw onion). However, for cooked preparations such as soups, stews, and stir-fries, this method performs just fine and will not alter the overall flavor.
Using a kitchen range hood or a nearby fan can reduce vapors that cause eye irritation when cutting onions. Running an exhaust fan, opening windows, or using an air purifier disperses the onion’s gases before they reach your eyes. Good airflow decreases concentrations of irritating compounds, allowing for a less painful chop of that onion.
If you regularly chop large amounts of onions, a small fan placed near your cutting board will help push the fumes away from your face, too. This is especially beneficial in small kitchens in which uncirculated air can trap onion fumes and raise the risk of eye irritation.
Most sulfur compounds are accumulated in the root of an onion. When you slice off the root end first, you release more of the irritating gas, resulting in a discomforting chopping experience. You can mitigate this by leaving the root intact as you slice through the rest of the onion.
One useful technique is cutting the onion in half, removing the skin, then making cuts but leaving the root end intact. Once most of your onion is chopped, you can trim off the bottom/root end. It makes all the difference in helping minimize the tears.
If cutting onions hurts you on a personal level, a food processor can be a good substitute. The processing limits direct exposure to the onion’s sulfur compounds, letting you chop onions in seconds without crying.
Make sure to use the pulse thing instead of constant blending so that you do not make the onions mushy. The technique allows the onion to keep its texture while being chopped effectively. Although food processors can be very efficient when preparing large batches of food, they are not suitable for dishes where very fine-diced or sliced onions are required.
It’s not news that tearing up while chopping onions can sometimes be avoided, and one of the easiest, most unforeseen ways to do it is by chewing gum. The act of chewing forces you to breathe through your mouth, thus minimizing the onion fumes that reach your eyes. This trick works surprisingly well for many people, as it prevents the sulfur compounds from accumulating near the tear ducts.
The technique works best in concert with other kitchen tricks, however, like wielding a sharp knife or working near a fan. It might not get rid of tears entirely, but chewing gum can be a quick and easy way that doesn't require arming yourself with tools or additional gadgets!
Getting through an onion without crying is completely possible if you are armed with the right techniques. There are many effective ways to Cut onions without crying, from chilling the onions or using really sharp knives to wearing goggles or cutting near a running tap. By understanding what the sulfur compounds do when a bunch of onions are freshly cut, you can minimize the fumes that make you tear up.
With these tried-and-true kitchen tricks, you can also turn food prep into a much more pleasurable experience. Whether you're a home cook or a professional chef, implementing these simple but effective strategies guarantees that cutting onions is no longer a teary affair. So, cooking should be fun, and with the right approach, you will be able to chop the onion without crying.
