Cubing potatoes is a great way to ensure that they are seasoned as much as possible. This is particularly important if you are intending to sauté the potatoes in a frying pan. While it is possible to cube potatoes with a knife, to get uniform, restaurant-quality potato cubes, you should use a mandolin slicer. Mandolin slicers have incrementally adjustable blades, meaning you can get almost any size potato cube you want.

Skill level:


  1. 1

    Adjust the cutting blade depending on what size potato cube you want. Aim to make the cubes at least 1/8-inch thick; otherwise the potatoes may disintegrate during cooking.

  2. 2

    Using the hand guard, push the potato lengthwise over the mandolin's blade. The slices of potato will be caught in the holder beneath the blade.

  3. 3

    Take out the slices and re-form them into the original shape of the potato. Run the potato through the slicer again, this time on its side at a 90-degree angle to the first time. Your potato should now be cut into even strips.

  4. 4

    Reform the potato once again and run it through the slicer a final time, pushing the strips of potato vertically through the blade. Uniform potato cubes will be collected in the mandolin's holder.

Tips and warnings

  • Use care to avoid cutting yourself on the mandolin's sharp blades.
