Step 1: Set up your food processor

To slice potatoes in a food processor (or dice or chop them) begin by assembling your device. Place the work bowl on the processor’s base. Some models require you to line up the bowl to the base and twist it on. Select KitchenAid® food processors feature a simple no-twist design for easy assembly. Finish by lowering the drive adapter onto the drive pin located inside the work bowl.

Step 2: Attach the blade

Attach your slicing disc or dicing kit to the top of the drive adapter. To chop potatoes, drop your multipurpose s-blade over the drive adaptor, turning until it falls into place at the bottom of the bowl. Securely attach your lid. If slicing or dicing, close the lid and remove the food pusher or any feed tube inserts to allow for the largest feed tube opening.

Step 3: Wash potatoes

Rinse your potatoes under cool water, utilizing a vegetable brush if needed.

Step 4: Peel potatoes

If your recipe calls for skinless potatoes, begin to carefully peel them by hand. Instead of discarding the leftover skin in your wastebasket, try some inventive ways to cook sustainably: such as tossing the potato skin in oil and seasoning and roasting it in the oven for an easy, salty snack.

Step 5: Prep potatoes for slicing

In order to properly slice your potatoes in a food processor, you must first take a sharp knife and cut your potato lengthwise into chunks. This may take several cuts, particularly if you are using large potatoes (when using a food processor that can process whole potatoes, like the KitchenAid® 13-cup food processor, you can skip this). Next, insert your potato chunks one by one into the feed tube.

If you are chopping your potatoes in a food processor, cut them into 1-2 inch chunks and add them directly to the work bowl.

Which food processor blades are best for slicing, dicing and chopping potatoes?

Because food processors can come with several types of blades to slice, dice and chop potatoes, a good rule of thumb is to let the blade name be your guide. Use a slicing disc to slice potatoes, a dicing kit for dicing and a multipurpose s-blade to chop. Keep in mind that not all food processors include each of these blades.

How thin you decide to slice your potatoes will entirely depend on which recipe you are following and what food processor you are using. That’s because select food processors come with thick or medium slicing discs for versatility.

Can I slice, chop or dice potatoes in advance before preparing a recipe?

It can be a good idea to prep your potatoes in advance to streamline your weekly cooking. Make sure that if you are slicing raw potatoes to store them in a bowl of cold water and refrigerate them for no more than 24 hours; if cooked, they will last three to four days in the fridge.

Can I use a blender to dice potatoes?

It is best to use a blender only when your final product is something you can drink, drizzle or dip. For non-pureed potato recipes, food processed potatoes are the right choice.

How can I prepare potatoes without a food processor?
