While you may think there’s not much to choosing a great onion chopper, when you start to dig below the surface there are quite a few different areas to take into account. In this section we’ll take a look at what these are to help you make the best choice for your kitchen and cooking habits.
There are three different types of onion chopper available to buy from the simple to the multi-purpose, so let us first have a look at what they are and how they differ.
Electric onion choppers let you quickly dice or mince at the touch of a button, so are perfect if you want a low effort solution to prepping your onions. They usually have a rotary spindle fitted with blades that is turned by the electric motor.
While they are really convenient and don’t take up too much space, you don’t always have as much control over the size of the pieces. It may take a bit of trial and error to get used to how quickly it powers through your onions, but it's definitely worth it for how quickly they get the job done!
Rotary onion choppers are sort of like small manual food processors, again with a central rotating blade on a spindle. However, this time, you turn the spindle and blade using either a push button or a pull string mechanism.
They are compact and quick to use and don't require much effort at all, so they're ideal if you have mobility issues or don’t have a great deal of strength. However, the nature of their design may mean that you need to replace them more often than other options owing to the push/pull mechanism.
Other manual onion choppers use a mechanism where you place the onion between the blades and a large push-down section, after which you press down and push the onion through the blades into a container below.
These are good in that they usually come with a variety of blades for you to choose how large or small you want your onion pieces to be. Of course, they do take more effort from you to push the onion through the blades and they are also much bulkier than rotary choppers, so you will need to find somewhere appropriate to store them.
While rotary choppers only have a spindle blade, push choppers can be supplied with a variety of different shaped blades so you can choose which size or shape you want your onions to be.
These include dices of different sizes and slicing blades, as well as julienne blades, graters and spiralizers which can help you prepare a wide variety of vegetables other than onions.
Onion choppers come in a wide range of sizes, and depending on how many you’re cooking for, you may need a larger or smaller amount of onions for your recipes.
To gauge how much space you will have in your chosen chopper for onions you should take note of the capacity which is usually expressed in millilitres or litres, as this will let you know how big or small it is.
Onion juice can be surprisingly sticky and it can leave a lingering odour on any cooking equipment if not cleaned up properly. And while this isn’t too much of an issue if you only need your chopper for onions, it could transfer the taste and smell of onion to other ingredients you want to prepare with it.
To help avoid this and also to keep it in tip-top condition for longer, you should pay close attention to how best to clean up the chopper after use. Hand washing is fine, but the easiest and most thorough way to clean it is in the dishwasher, so you may want to check whether it is dishwasher safe.
Onion choppers can come with some really useful additional features such as a non-slip base or an integrated colander. Manufacturers go to long lengths to make sure their product is as practical and useful as possible, so these extra features can be all sorts of things.
While this doesn’t affect the overall function of the product itself, they can make it much easier to use and give much more added value – something most of us are always looking for when buying kitchen equipment!

This is a really handy mini chopper that's sure to be come one of your most used kitchen gadgets when preparing delicious meals.
The four interchangeable blades in this model let you julienne, chop and slice vegetables with ease. Better still, the cut foods fall directly into a large 1.2 L collection tray. The soft grip handle is a great addition for better leverage, and the rust resistant heavy-duty blades allow for crisp, smooth cutting and grating.
This chopper is excellent at dicing onions and softer veg, but if you want to cut harder veg such as carrots or potatoes, you may need to first cut them into smaller pieces to make it easier. This aside, it saves you so much effort and time when cooking and is worth every single penny!
With its large 8.5 cup capacity, this chopper will enable you to make short work of prepping big quantities of vegetables and herbs for your meals. The push button action is very easy to use even if you have reduced mobility, and it is compact and easy to clean.
The blades on this chopper are very very sharp, so you will need to be careful when lifting it in and out of the cupboard and also when washing it. But this is also a plus as it means it powers through your onions and veg in no time!
The lid of this chopper is equipped with a safe locking design that keeps it firmly attached to the bowl, and the anti-slip bottom stops the unit from sliding around as you work. It allows you to cut, slice, and chop any ingredient to any size you want in seconds, and it comes apart for an easy clean up.
The capacity of this chopper isn't overly large, so it is best for when you want to slice up smaller quantities of onions and veg. However, it needs minimal effort to use and it is sure to save you a lot of time and space for quick meal prepping.
The 900 ml bowl in this chopper is perfectly sized for a wide variety of uses, from chopping onions to blitzing up a hummus or dip. The blades stay in place even when you tip the bowl upside down to pour your ingredients out too, and the pulse buttons for chopping or grinding are a great addition.
It is fantastically compact and sits in any small space unobtrusively, whether that's a worktop or cupboard. It would seem the motor is underpowered for the size of bowl, as when you fill it over the half-way mark the blades slow down and can stop – perhaps just make sure not to overfill it.
OXO's chopper quickly and safely chops fruit, vegetables and more in one easy motion, and the convenient opening allows easy pouring without lifting the lid or taking it apart. The lid has been ergonomically designed to provide good leverage for easier chopping too.
One thing to note is that the blades are quite stiff to remove from the base unit so care is needed when cleaning it to avoid any sliced fingers or hands. But once you get the knack of removing them, this is a really efficient chopper from the experts, and the easy-pour feature really is a game changer!
This is a high quality mini chopper operated by a gentle pull of the ring which then turns the blade inside. It has a two-cup capacity and is very compact making it ideal for smaller kitchens, or even taking camping owing to the lack of battery or power required.
This chopper also gives you great control and is very easy to assemble and use. Care is needed when cleaning it to make sure that the cord doesn't get wet, which could lead to mould growing inside the housing – just a quick wipe of the pull cord unit is best.
Sedhoom's chopper comes with five interchangeable blades of different sizes, meaning you can slice and chop a lot of onions in mere seconds. Made from food-safe plastic with rust-proof stainless steel blades, the non-slip feet keep it steady as you work and the extra accessories make cleaning up a doddle.
This chopper does take a bit of effort, and anyone who struggles with weakness or injury may find it too hard to use. If this doesn't apply to you, however, then this is a great value option that can make meal prep so much quicker. It also comes with some handy accessories which is always a bonus!
Make light work of onions, vegetables and many other foods with this machine from Tefal that can chop, mix, mince, grind, crush and emulsify. The two sets of sharp blades provide optimum efficiency for better results, and the powerful 500 watt motor will stand up to most tasks.
In terms of downsides, the instruction booklet provided is quite difficult to understand which may cause some issues. Also, the powerful motor means that if you leave your finger on the button a fraction too long, you end up with very fine dice. Master this, though, and you'll find that it is very useful and cleans up a treat.
If you prefer the more old fashioned approach to cutting, slicing, and dicing your fruit and vegetables, then we have some fantastic recommendations for kitchen products that will take the hard work out of meal prep.
