This is especially problematic with garlic, but onions, roots and other vegetables are sometimes just as bad.

When making thin slices, with the problem worsening as the portions are cut smaller, the garlic clings to the blade and I have to wipe it off after each go. Are there any tips or tricks used to prevent this?

I've never seen a chef on a cooking show do anything special to their blades beforehand, and they never seem to have the problem. My knives are high quality and very sharp.

  • This bother me too. Might oil work (I doubt it)?

  • @rumtscho so that covers garlic. I've never seen a cooking show where this happens though, do you think they wet/oil up their blades before hand?

  • Could you tell me why you need to wipe off the vegetable slice between each go? Just cut through the vegetable again and it will slide off. There is a problem with this if you have a small cutting board (it can fall off), but a large cutting board is almost as important as a sharp knife.

    @citizen See my comment to Kate Gregory, but it's mainly an annoyance when mincing garlic. The suggestions to keep cutting may help with larger sliced portions but when I want a fine mince or chop it's still a problem

You could look at your knife skills. Professional cooks are either faster than ordinary cooks, so the food doesn't have time to adhere to the blade, or maybe their knives are sharper. Do you hone your knife (correctly) before you start cutting?

Another thing is the way professional cooks cut, they use the knife to slice through the food making a slicing motion. Some people just press their knives against the food and apply pressure, which is the wrong way.

Lastly, when dicing, you could make one or two horizontal cuts, then nine or more vertical cuts... without cutting through the base. This way, the food is still attached to the base and will not stick to the knife. Lastly, you turn the food 90º and make the last cuts to create smaller or larger dices.

Edit: There are knife blades designed to reduce the food sticking to them. They have dimples or 'cullets'.


I just ignore slices that stick to the blade. Each typically gets pushed off by the next one, so you only have one or perhaps a couple of slices on the blade at a time. When I've sliced the whole thing, I can wipe them off. This doesn't work when you're rough-chopping, in that delightfully casual way the TV chefs say "just run your knife through it all a few times" since half the stuff is on the blade, but it does work when you're slicing a carrot or garlic or whatever.

Just now, I sliced potatoes thinly for gratin and noticed that I semi-automatically gave each slice a little shove, using one of the fingers from the hand that was holding the potato, just as the slice finished. Obviously this only works for slices large enough to stand up past the top of the blade, but it's a technique you can use for some roots and veggies, even if not for garlic. I'm pretty sure I don't do that for things I intend to chop again in another direction, but only for things I am slicing.

    so say I'm mincing fresh garlic, and the larger sliced pieces are adhering to the blade while I more finely chop the rest, so I have a bunch of mixed sizes. Ignoring the larger ones stuck to the blade isn't going to make them magically the same size as the rest..

  • Slice the whole thing one way. When you've finished slicing, wipe off the one or two slices that are still on the blade, gather everyone together, and slice the other way. Don't wipe off each slice as you do it, that's too time consuming for no gain. Commented Jan 16, 2013 at 14:11
  • Right, which is how I do it now. But my question was more of how to prevent the sticking from happening at all.

    I don't think your going to have much luck making garlic not stick, it's naturally a sticky ingredient and yes it sticks to the blades of the tv cooks all the time they just wipe it off quickly or with tv magic cut back to a pile of minced garlic. If you truly are pissed about it get a garlic press.

  • @Kate Gregory if prepping several kinds of veg, especially to different sizes or to be added at different times, leaving anything on the knife when changing veg is not a option - garlic pieces in onions that are supposed to be fried golden brown will be literally bitter news. Also, a mix of eg garlic slices and brunoise dice will cook very unevenly :) Commented Oct 21, 2016 at 9:10

It helps a lot if you wet your knife blade before mincing garlic. It'll still stick to the blade some, but not quite as much, and what's left is a lot easier to brush off.

For bigger things, you can try knives with dimples (like Kyle suggests), and sometimes a wet blade helps here too, but these things only go so far. Stuff is going to stick, and the key is to learn to deal with it sticking. One thing that really helps is to slice with the knife angled slightly, cutting just a bit toward the bulk of the vegetable, so that the slices are tilted away from it and when they get pushed up and off the blade, they fall away from the part you're chopping and don't get in your way. You'll probably still feel the urge to brush it off, but eventually you'll get used to letting it fall.

Beyond that, BaffledCook's tips on knife skills are good - read and upvote them too!


I have this same exact problem and for me the solution was to use a hollow edged knife instead of a hollow ground one. The little pockets on the knife allow the air to separate the slicing easily instead of it being stuck to the blade.


With garlic, give it a rough smash and chop, then let it sit with some salt (preferably coarse) for a couple of minutes. That makes it much less sticky.

    Why coarse? How does the salt reduce the stickiness? Is it just adding the physical abrasiveness?

  • not to mention you're still suggesting I chop it first, and waiting around for it to sit with salt doesn't really save time.

  • I don't think you have to use coarse salt - that's just how I learned it. And I don't know how it works but it does! You don't have to let it sit too long so you do end up saving time because you aren't cleaning off your blade constantly.
