How to Use a Food Processor To Slice Potatoes

Now that we’ve established that you can indeed use a food processor to slice potatoes, let’s elaborate on the steps above to get started. The following instructions should apply to most food processors.

Step 1:

You always want to start with clean potatoes, so wash first. If your potatoes are incredibly dirty, you may have to scrub them. You don’t want to use a standard kitchen sponge for this, but a vegetable brush like the OXO Good Grips brush will do the job.

Wash your potatoes with cool water and then dry them with a paper towel or a clean dishtowel.

Step 2:

Next, remove the skins from your potatoes if your recipe calls for it. Making homemade French fries or potato chips will require you to keep the skin on, but for scalloped potatoes, you won’t want the skin.

You can use a knife (be careful if you do!) or a potato peeler to remove potato skins. Some chefs even boil the potatoes until the skins slip right off, but depending on which potato dish you’re making, you might not want to do that because it pre-cooks the potatoes.

Step 3:

Slice your potatoes into manageable pieces. If you have mid-sized potatoes, cutting them in half should suffice. For bigger potatoes, cut the halves in half and maybe split long pieces lengthwise. Think about your particular food processer and what kind of load it can handle when cutting your potatoes down to size.

Step 4:

Plug in your food processor, open or remove the lid, and add your potatoes into the opening. Push the plastic plunger in so your potatoes go through to the blade. We recommend feeding one potato into the food processor at a time.

Step 5:

If your potato pieces are still too big, put them through the food processor again.

Here’s a handy video illustrating the above steps if you want to see a food processor in action slicing potatoes.

How Do You Keep Homemade Potato Chips Crispy?

Let’s say you used your food processor to make potato chips at home. You couldn’t be more thrilled with how they turned out. You don’t eat them all the first night, so you set them aside for later. A day or two after you made them, the chips are now soggy and limp. Oh no!

What happened? Moisture or excess frying oil got to your chips, softening them up, so they’re more potato-like than crispy. To prevent this problem in the future, you can do two things.

First, after your chips come out of the oven and get a chance to cool, blot them on paper towels to remove any leftover oil. Then, keep them in an airtight container so moisture can’t get in. Your chips will stay crispy even several days after making them!

How Can You Slice Potatoes Thinly Without a Food Processor?
