How to Cube Potatoes

Cubed potatoes are called for in a variety of dishes, from breakfast potatoes to potato salad. Because of their irregular round shape, cutting potatoes into cubes can be a bit difficult. You'll need to slice off all of the potato's rounded edges to create a rectangular shape needed for equal-sized cubes. A good quality chef's knife makes it easier to slice the potatoes evenly, although it can take a little time to master.

Step 1

Peel the potatoes with a potato peeler or paring knife. Place the peeled potatoes in a large bowl filled with cold water. This will help keep them from browning before you are ready to use them.

Step 2

Place a potato on a clean cutting board. Cut off the rounded edges on all sides of the potato to create a rectangular block.

Step 3

Cut the potato lengthwise into evenly-spaced slices. Stack the slices on top of each other and slice them lengthwise again, using your non-dominant hand to hold the stack steady.

Step 4

Turn the potato slices 90 degrees, again using your non-dominant hand to hold the stack steady. Cut across the potato slices at even intervals to create equal-sized potato cubes. Repeat with the rest of your potatoes.
