Being able to get thinly sliced potatoes for potato chips is a pretty tough task if you don’t have a mandoline.

After all, getting the slices that thin while keeping them all the same size is a task that professional chefs might even struggle with.

But that doesn’t mean it’s impossible.

You can thinly slice potatoes without a mandoline by using the slicer attachment on your food processor. But if you don’t have one on hand, you can also use a vegetable peeler or a cheese planer, making sure to apply a firm but even pressure when slicing.

In recent years, there have been a lot of different techniques for thinly slicing vegetables that have risen in popularity, mostly because it doesn’t require owning a mandoline, which can be a fairly expensive tool to have in the kitchen.

And in this article, we’ll be taking a look at a couple of techniques that you can use to slice potatoes thinly without a mandoline in the comfort of your own kitchen!

Read on to learn more.


How To Slice Potatoes Thinly Without A Mandoline

Use A Food Processor

If you happen to have a food processor on hand, you’re in luck, as you can use this to easily slice potatoes very thinly and evenly in a matter of minutes.

Most food processors out there will come with a slicer attachment, and some even come with multiple slicing attachments!

But if your processor doesn’t have one, you can easily check online stores or your local kitchen appliance shop to check if they have one fit for youro model.

You won’t be able to control the thickness of the slices that much, and depending on the attachment you have, you might only be able to get them to about a quarter of an inch thick, but this is a very easy and convenient way to thinly slice your potatoes.

To use this method, simply attach the slicer bit of your food processor to the top of the machine, turn it on, and carefully feed in the potatoes from the top of the processor.

Ideally, you would want to use a handguard or food pusher for this task to avoid any unwanted accidents.

And in a matter of seconds, you’ll have thin and even potato slices ready for frying!

Use A Vegetable Peeler Or Cheese Planer

If you’re looking to get very thin slices on your potatoes and you want to do it quick, a cheese planer or vegetable peeler is your best bet.

A vegetable peeler tends to do the job better as they are sharper and can slice through ingredients better, but if you don’t have one on hand, a cheese planer could do the job fairly well too.

To start, you’re going to have to choose if you will peel the vegetable first or not.

The choice is all up to you, as some people prefer to have skin on their potato chips while others don’t.

Once that is decided, all you will have to do is hold the potato in your non-dominant hand, and use your dominant hand to slice it using a vegetable peeler.

Make sure to apply a firm, but even pressure when doing this to ensure that it will slice cleanly and evenly.

If you want more stability, you can even lay the vegetable down on the table, hold it in place using a fork, and use either your planer or vegetable peeler to get the job done from there.

This method may take some time, but it’s one of the best ways you can get thin and even slices without having to use a mandoline.

Use A Sharp Knife

This is arguably the toughest method out there, and it will take some skill and practice.

In fact, some professional chefs still have a hard time getting very thin and even slices using a knife.

That being said, make sure to use a very sharp knife so that you can slice through ingredients much easier.

With this method, you probably won’t be able to achieve the thinness you would want for potato chips and they might not even be as even as you’d like, but this is still an ideal way to slice your potatoes if you have no other tools on hand.

To be able to get a nice and thin slice with a knife, make sure to slice evenly and carefully, and if your knife is very sharp, you will have a much easier time as compared to having a dull blade.

Again, this option should only be used if you have no other tools on hand, but with enough practice and patience, you’ll surely be able to get thin potato slices using a knife.


And with that, our guide to slicing potatoes thinly without a mandoline has come to an end.

There are many ways you can get this job done, but if you have a food processor or vegetable peeler, it will be much easier to accomplish.

But if you don’t, then you can always choose your sharpest knife, and with enough care, you’ll be able to get thin potato slices that are ready to turn into potato chips in no time!
