Frequently Asked Questions

What knife is best for cutting onions?

If you are looking for a knife that can help you cut through onions with ease, you should consider going for chef knives or santoku knives with hollow ground edges.

These knives have reliable blades that will allow you to cut with no drag even when slicing sticky foods.

Should you use a serrated knife for onions?

Serrated knives are not efficient when it comes to chopping onions because the serrations won’t deliver clean cuts.

How do you cut an onion without it sticking to the knife?

The best way to go about this is by cutting the onion in a rocking motion by pushing the knife up and down as you pull on the blade.

As a result, the surface of the blade won’t be in contact with the pieces of onion that you have already chopped compared to when you cut the regular way.

What size of knife is best for cutting onions?

Most users prefer chef knives that are between 8 and 10 inches long since they allow for fast and easy cutting.

What is the fastest way to cut an onion with a knife?

Cutting an onion can be a bit difficult if you hold the onion the wrong way. To make your work easier, you can start by dividing the onion bulb into two halves.

After that, you should make vertical slits on one of the pieces. When you are done, make one or three horizontal slits depending on how large or small the onion is.

The last step involves chopping the onion into smaller pieces whereby you are required to hold the onion firmly against the surface of the cutting board as you slice through it in a rocking motion. Repeat this process with the other half and you will be done in no time.

Final Verdict

You can make your work easier when cutting onions by using the high-performance knives in our detailed review list.
