Unless you’re a professional chef, adept in the secret world of knife skills, it probably takes you ages to prep just one onion. And let’s face it –there’s nothing fun or glamorous about chopping onions. It’s often the least exciting, most boring part about preparing a meal and yet most savory meals are incomplete without them. Despite being a necessary mealtime component, they make your hands smell, they make you cry and, even more frustratingly, they take ages to get just right.
That’s where onion choppers, slicers, and/or dicers step in. They take all the frustration out of onion prep, allowing you speed through them with ease and efficiency. If precision isn’t your forte and you find yourself spending ages laboring over perfectly diced onions, using an onion chopper means you’ll be able to produce consistently diced and sliced onions in record time.
What Are Their Limitations?
While some of these units can certainly process things besides onions, they often limited in the types of cuts that they can make.
With the use of a knife, you obviously have the capability to cut things to any shape, thickness, or style that you want. By using an onion or vegetable chopper, you're trading precision for convenience and function.
If you want to do make the ever popular zoodles or zucchini noodles you're going to need a zoodle maker or spiralizer. For certain fruits such as apples, an apple peeler, corer, slicer is probably the best option.
What Are the Differences Between These Models?
Ever heard the expression “there’s more than one way to skin a carrot?” Well, there’s more than one way to chop an onion. With more and more onion chopping gadgets hitting the marketplace, it can be hard to know what model to go for.
Before deciding on what onion chopper you’d like you must first identify what you’d like your onion chopper to do. Do you want finely diced onions to add to tacos, curries, stews and casseroles?
Or are you looking for onions chopped into perfectly formed moons and half-moons?
Maybe you’re looking for something that can do both.
Once you’ve figured out what you’d like your onion chopper to do, then choosing one is easy.
Some onion choppers come with built-in containers, which catch the onion while you work. This eliminates onion vapors, meaning you don’t ever have to worry about onion-related tears again.
Other onion prep tools and are comprised of a sharp comb-shaped gizmo that allows you to dice the onion into uniform pieces. These aren't really onion choppers themselves, but holders which allow you to make perfectly uniformed onion slices. Great for topping sandwiches or making onion rangs.
There are even some onion choppers that have multiple blades allowing you to create onion rings and half rings as well as slicing them up into small pieces.
Whichever model you decide to go for, they reduce your prep time, allowing you to spend more time doing what you love. Onion choppers are also small and compact, meaning they won’t take up much room in your cabinets. They are all low-cost items that make a great addition to any kitchen.

This handy little slicer dicer comes with three mandoline inserts, a juicer top, chopping blades, and more.
When it comes to onions though, you're probably going to want to use one of the three slicers or the chopper blade.
To do a rough chop on onions, or make a salsa, you're going to want to use it like a manual food processor.
Once you set up the blades, you simply put the onion into it and turn the crank to start the blades. Within seconds you'll have an onion that's roughly chopped.
Say you want to slice or grate, you simply attach the alternative top onto the unit and use it like a mandoline slicer. The onions or other vegetables will fall into the container, keeping the smell and the crying to a minimum.

Oxo Good Grips Complete Slicing and Grating Kit
The great thing about the OXO good grips slicing and grating kit is that it has a set of steel blades for almost anything you could want to do. Whether you're grating ginger or slicing onions, you can expect high quality blades when you're going with an OXO.
Included with the product you get the following four blade sets: one medium grater, one course grater, one regular slicer, and one julienne slicer.
The entire unit functions similar to a mandoline slicer in that you slide the vegetable across the top.
However, unlike a normal mandoline, the cut or grated onions will fall into the container at the bottom. With measuring marks included in the container, you'll be able to assess how much more you need to cut. You'll also reduce the onion vapors by keeping them contained.
When you're done, everything fits away together in a neat arrangement with all four blades stacked away for safe storage.

Simply attach the blade, load the roughly pre-cut onions into the container, and pull the string! Within seconds your onions will be diced inside the container.
Because a majority of the dicing/chopping was done in the 4-cup bowl, the amount of vapors released from the onions is greatly reduced.

This list wouldn't be complete without having one high-quality mandoline slicer on it. Second to using a knife, a mandoline slicer is a go-to gadget for anyone savvy in the kitchen.
A mandoline slicer can make uniform onion slices quickly and effectively. All you need to do is peel the onion, attach it to the holder (for safety) and slide it across the blades.
Not only is it great at slicing, but you can also do grates and julienne cuts as well. It's hard to think of any fruit or vegetable that wouldn't function well in this mandoline slicer.
The only downside to a mandoline slicer is that once you get down to the bottom of whatever you're prepping, it can be hard to continually slide it across the blades. It's especially recommended that you use the holder at this point and throughout the entire process, because its quite easy to cut your fingers.

This onion chopper is also good to use on odd-shaped veggies like portabella mushrooms and olives.
All three blades come with locking mechanisms rather than snapping into place, making this onion chopper safe and reliable to use. Each blade carries out a different chopping function: one can be used to julienne your veggies, another can be used to slice and the third one is for dicing food into small cubes.

Its small enough to take out on a whim and easy to store when you're not using it.
This is the third food processor on the list, although this one you actually need to plug in, unlike the Briefton's manual food chopper.
Although we'd probably recommend the Briefton's at the end of the day, this is a great alternative if you want less manual work. You'll still need to pre-cut the onions unless they are tiny ones, but you won't have to pull a string to turn the blades.
