Onion Chopper and Onion Dicer Buyer’s Guide

The images of an onion chopper and an onion dicer look straightforward and promising. However, there’s always more to them than when you first see them. Before you purchase your means of cutting onions, let’s go over certain features and qualities to help you decide.

Manual or Electric

Perhaps you prefer putting in less work with cutting onions or you prefer being in control of the chopping process. With manual choppers, you’ll get either uniform pieces or customized cuts, while electric ones just cut in random shapes.

Noise preferences are another factor when comparing an electric and non-electric onion chopper and onion dicer. You can either flip a switch, resulting in white or undesirable noise, or manually commence quiet chops.

What really sets the two types apart is a matter of location. Electric onion choppers and dicers require a location with an outlet, but manual ones can work anywhere. The choice is yours!

Ease of Use

You want to be able to use an onion chopper or onion dicer without any difficulty. Perhaps you want one that isn’t so hard to use the first time you chop or dice. A device that has a non-slip base is a bonus since stability is factored into chopping and dicing with ease.


How many onions do you usually prepare for your meals, depending on the recipe or the number of people eating? Or how many onions are you planning to chop and store for when you plan future meals?

Most containers where the cutting takes place or that hold the pieces after being cut range from 1 to 4 cups. You want a chopper or dicer that will hold as many cut onions as necessary. But you’ll also want to consider the storage space when looking at the cup size.

Easy Cleanup

Your onion chopper or onion dicer should be easy to wash or simply clean up after using it. The last thing you want is to be unable to remove leftover remnants from the blades for fear of cutting yourself.

Being dishwasher-safe is a bonus, as you wouldn’t have to dodge the blades as you’re handwashing the chopper or dicer. If your chosen product comes with a cleaning brush, that will ensure an easier wash whether it’s dishwasher-safe or not.

Blade Quality and Number

Sharp, durable blades are necessary for chopping and dicing onions. Stainless steel is the blade material to look for. You don’t want them to become rusty or dull after only a few uses.

When evaluating onion choppers and dicers, try finding one that includes more than one size of blade. You’ll have more ways of cutting onions if you purchase a device that lets you decide the sizes of the pieces.

Onion Chopper and Onion Dicer Frequently Asked Questions

How can I fit a whole onion under an onion chopper or onion dicer?

You can’t just put a whole onion in and press down or pull a drawstring. You’ll need to prep it for a good fit. It requires at least three cuts, but the chopper will do the rest of the work.

Chill an onion for 30 minutes in the refrigerator to slow the vapors’ release when it’s time to cut it. After removing the onion from the fridge, cut off the nodes on each end and throw them away.

Peel off the skin and wash the onion. Then cut it in half, place one half on the chopper, and proceed.

What does BPA-free mean for certain onion choppers and dicers?

If you see a feature that says BPA-free, it’s important to note what this acronym stands for. BPA means bisphenol A, a chemical used for certain plastics in commercial products that hold food and drinks. Unfortunately, this chemical has health risks as it touches the food you chop.

BPA is even more of a risk for your food and drink if the plastic is exposed to heat. People who are trying to avoid BPA exposure will likely purchase an onion chopper or onion dicer that’s labeled BPA-free.

If the devices’ blades become dull, can I sharpen them?

When knife blades dull over time, we have the ability to sharpen them so we’re not struggling with making a smooth slice. As for blades on an onion chopper or onion dicer, attempting to sharpen them could likely damage them.

Most of the choppers have stainless steel blades, which are designed to be sharp and durable. If they dull over time, it’s safer to order more blades from the manufacturer.

Can food processors chop and dice onions too?

That depends on the number of times you use them to chop and dice the onions. It also depends on the setting you put them on if they’re electric and come with other preparation options.

It may not matter to some people, but with a food processor, your onions won’t be cut in uniform shapes.

Chop and Dice Onions Without the Tears!

Besides learning the hacks to tear-free onion cutting, save yourself time by purchasing an onion chopper or an onion dicer. Food preparation doesn’t have to be a lengthy task, let alone make you cry while you’re doing it.

We highly recommend the durable Mueller Onion Chopper. It’s easy to use, holds a good capacity of chopped onions, and offers injury-free cleaning.
