The Best Onion Chopper: Our Picks

Buying and Evaluation Criteria for Onion Choppers

In this section we show you which aspects are important when buying an onion chopper.

The following criteria will help you compare onion choppers with each other:

In the following, we explain in more detail what you need to consider for each criterion.

Material

An onion chopper consists of various components. When choosing the right material, you have several possible combinations. In this way, you can choose your onion chopper according to your taste.

A plastic housing is easy to clean and available in different colours. However, if you place a lot of value on the look, stainless steel is the right choice for you. Stainless steel is rustproof and also robust.

With most models, you can choose between stainless steel and plastic.

Most containers are made of plastic. This material is easy to clean, but has a certain susceptibility to scratches. If you want a higher-quality material, glass or stainless steel is an option. However, the container is then considerably heavier.

When it comes to the blades, the decision is much easier. Stainless steel blades are the best choice. They are rustproof and cut particularly sharply.

Number of blades

Many onion choppers have rotating blades. But which number of blades offers the best result?

Make sure that the blade is sharp.

It is often said that more blades give a better result. However, you should rather make sure that the blades are sharp enough. The sharper the blades, the better they cut.

There is an alternative to rotating blades. Some onion choppers work with a folding mechanism. Instead of blades, they contain a blade grid. With different attachments, you can choose how big you want the chopped pieces to be.

The number of blades you choose therefore also depends on the type of onion chopper drive. We have summarised below which is the right one for you.

Capacity

Another important criterion is the capacity of the container. This is indicated in millilitres and shows what quantities the container can hold. The range is from about 100 to 2000 millilitres.

The standard is 400 to 900 millilitres.

Which size is right for you depends on what you want to use the onion chopper for. If you often process large quantities, a large capacity makes sense. Otherwise, fewer millilitres will suffice.

In addition to the quantity, the use of the onion chopper as a multifunctional device is important for the choice of size. If you also use the appliance to chop other types of vegetables and fruit, a larger capacity makes sense.

If you don't want to decide, there are onion choppers with a folding mechanism without a container. It is also possible to buy sets. Then you can choose the right container according to your needs.

Weight

The weight of an onion chopper varies from one model to another. You can buy onion choppers weighing between approx. 190 and 1500 grams.

Electric onion choppers are heavier than manual ones. They require additional electronics. Depending on where you want to store the onion chopper, you should find out beforehand.

The type of drive, material and size influence the weight.

Manual onion choppers are operated by hand and should be lighter. Note that the material and size also influence the weight. If you want a lighter product, you should also consider the material.

Dishwasher safe

Some onion choppers are dishwasher safe. This makes it very easy to clean, especially if they are made of plastic. If you are unsure whether the appliance is dishwasher-safe, it is best to check the operating instructions.

However, we recommend cleaning by hand. This is gentler on the material. Blades quickly become blunt in the dishwasher.

We have summarised more useful cleaning tips for you in our guide. There you will also find more answers about onion choppers.

Guide: Frequently asked Questions about Onion Choppers answered in detail

In the following, we have summarised and answered the most important questions about onion choppers. This will provide you with the most important background information on the topic.

Who is an onion chopper suitable for?

For people who like to cook, an onion chopper is a must. Even if you are rarely in the kitchen, buying an onion chopper makes sense. The onion chopper offers many advantages:

  • Chopping onions without tears
  • No onion smell on your fingers
  • Fast chopping
  • Easy to use
  • Often multifunctional

When the onion is chopped, two substances from the cell combine to form a gas. This irritant then triggers the tears. With an onion chopper you avoid the tears. A nice extra: you don't have to hold the onion in your hand and you don't have the smell of onions on your fingers.

Onion choppers are versatile. You can chop other vegetables or even nuts with them. This is important if you want to save time or cook a lot in general.

Professional cooks chop the onions with a knife. This way they avoid the risk of the onion pieces becoming uneven. However, in any household kitchen, the onion chopper is a practical tool.

How does an onion chopper work?

Onion choppers are divided into two types of drive models: electric onion choppers and manual onion choppers.

The electric onion chopper is very uncomplicated and requires electricity. Depending on the model, you can choose different speed levels. The blades then chop the onion.

A manual onion chopper is operated by hand. There are four different types of drive:

Drive type Description
Folding mechanism Onion choppers with a folding mechanism have a blade grid in the lid. You first place the onion on the cutting surface. Then you close the lid with the blade grid and chop the onion.
Turning By turning the lid, you move the knives in the container and cut the onion.
Pull cord The lid of the onion chopper has an integrated cord. When you pull the rope, the knives inside the container rotate and you chop the onion.
Push down Onion choppers to push chop rather than cut. If you press the handle down repeatedly, the zigzag-shaped blade chops the onion from different angles.

Each product may be different in how it is used. If you are unsure, it is best to check the instruction manual.

What types of onion chopper are there?

If you want to buy an onion chopper, there are two types of products you can choose from:

Type Advantages Disadvantages
Electric onion chopper No power required, powerful Requires electricity, more expensive
Manual onion chopper Does not require electricity, already available at a low price Power required, partially coarse chopping

In the following two sections you will learn more about the two types of onion chopper.

Electric onion chopper

Electric onion chopper

An electric onion chopper offers the great advantage that it can be used without any effort. This advantage helps you to chop large quantities, which is very tiring with a manual onion chopper.

You also save a lot of time with an electric onion chopper. When you chop large quantities, an electric onion chopper is much faster than a manual one. Even small portions are quickly chopped.

Advantages
  • can be used without force
  • suitable for large quantities
  • not time-consuming
  • powerful and effective
  • multifunctional
Disadvantages
  • needs electricity
  • inflexible work surface
  • higher weight
  • more expensive

The electric tools are very powerful. They cut very finely and are therefore effective. This gives you the opportunity to cut other vegetables and even nuts. The appliance can therefore be used multifunctionally.

The disadvantage of the electric onion chopper is that it has to be connected to a power source. This makes it less flexible for the work surface. In addition, electric models are heavier than manual onion choppers because of their electronics.

Finally, you should be aware that the electric onion chopper is more expensive overall. They are more expensive to buy than manual ones and require additional electricity, which has to be paid for.

Manual onion chopper

Manual onion chopper

There are different ways of operating manual onion choppers, which differ from each other. We have listed the advantages and disadvantages that definitely apply to all manual onion choppers.

The big advantage of manual onion choppers is that they do not need electricity. Therefore, you can use them flexibly and find a place for them even in small kitchens.

Advantages
  • does not need electricity
  • flexible work surface
  • cheaper
  • easy to use
Disadvantages
  • requires a lot of power
  • takes a lot of time
  • sometimes no fine chopping

Manual devices are cheaper to buy than electric ones. Overall, there are variations between the different models. Since you do not need electricity, you save the electricity costs of an electric device.

All models are easy to use. However, the application requires a lot of force. You should definitely consider this before buying. Manual chopping also takes longer, depending on the amount to be chopped.

Finally, it can happen that you do not achieve an evenly fine chop with manual use. However, this depends on the sharpness of the blade and the type of drive you use.

How much does an onion chopper cost?

There is a very wide price range for onion choppers. The price is related to the brand name and the quality. The range is between about 3 and 200 euros. Onion choppers made of higher-quality materials cost considerably more.

You can buy manual onion choppers from around 3 euros. The lack of electronics makes them cheaper.

Depending on additional extras, such as more containers or blades, and on the material, the price of manual onion choppers can rise to around 110 euros.

Type Price range
Electric onion chopper approx. 22-200 euros
Manual onion chopper approx. 3-110 euros

The differences between the manufacturers are great. Simple electronic onion choppers are therefore available from around 22 euros. Depending on the manufacturer and material, the chopper can cost up to about 200 euros. Stainless steel is much more expensive than plastic, but looks more elegant.

The material and the manufacturer are also decisive for the price. When making your decision, you should also consider how often you plan to use the onion chopper.

What are the alternatives to an onion chopper?

The alternative to an onion chopper is the kitchen knife. Professional cooks tend to use this because the onion can be crushed in the chopper and then become slightly bitter. In addition, they do not run the risk of the pieces becoming irregular.

The knife must be very sharp. This way, the onion cells are not damaged as much and the irritant substances are not released. In addition, cutting onions is faster with a sharp knife.

How do I clean an onion chopper?

Many models are dishwasher safe. If necessary, you can easily clean most parts in the dishwasher. However, we recommend cleaning by hand. This protects the material and increases the durability.

Knives become blunt more quickly in the dishwasher. Water can also get into the inside of the lid. Onion choppers with a drawstring in the lid can be damaged in the long term.

Cleaning under running water is best.

We therefore recommend cleaning under running water. Most onion choppers can be broken down into individual parts and are then easy to clean. Make sure that you clean the appliance thoroughly to remove all residues.

Before cleaning electric onion choppers, unplug the appliance from the power source. Do not get the plug wet. Be careful when cleaning the blades. They are very sharp and there is a risk of injury.

Where can I find spare parts for my onion chopper?

You can either find information about spare parts on the website of the respective manufacturer or you can contact the customer service. Often there is also information on spare parts in the operating instructions.

Especially with more expensive appliances, it is worth buying spare parts instead of a new appliance. For lower-quality models, you should consider whether it is worth buying a new unit.

A replaceable set of blades makes sense. Onions can only be chopped optimally with sharp blades. If your blades are not replaceable, you can sharpen them with a knife sharpener.
