    Wedges

    Any potato can be cut into wedges, but yellow, Yukon gold, and red potatoes tend to be the perfect size for cutting wedges. To start, scrub the potato clean. If you prefer to peel your potatoes, do so now. Then, cut the potato in half lengthwise.

    Next, cut each half lengthwise into quarters to make 4 wedges per half (8 per potato). For very large potatoes, you may be able to get 6 wedges per half.

    If you want to cut potatoes for mashed potatoes, follow the first step here of halving the potatoes. Then, instead of quartering each half lengthwise, quarter crosswise to get chunks of potato to boil then mash (make a cross with your knife on each half of the potato). Use the same technique when preparing potatoes for potato salad.

    Fries

    Russet potatoes are my favorite type to cut into fries, but you can use most types of potatoes with this method. Begin by scrubbing the potato clean and peeling if desired. Then, cut the potato lengthwise into ½-inch thick slices.

    Stack some of the slices (or “slabs”) on top of each other. Cut lengthwise into fries about ½-inch wide.

    Cubes (Diced)

    To dice a potato, first cut it into fries following the above instructions. Then, cut the fries crosswise into ½-inch cubes for a medium dice. For a small dice, cut into ¼-inch cubes, and for a large dice, cut into ¾-inch cubes. This is the best way to cut potatoes for soups and stews.

    Slices

    Sliced potatoes are great for making scalloped potatoes, other types of potato bakes, and pizzas. You can slice any kind of potato into circles. First, scrub clean and peel if desired. Then, slice the potato crosswise into pieces of your desired thickness.

    Julienne

    Potatoes that have been prepared with the julienne technique are skinny pieces about 1/16-inch wide and 2 to 3 inches long. They are great for cheesy potato recipes, skinny/shoestring French fries, or as an alternative to shredded hashbrowns. Yukon gold, yellow, and red potatoes all work well for using the julienne technique. First, scrub the potato clean. Next, slice off the sides and ends to yield a rectangular piece.

    How to Store Potatoes After Cutting

    Potatoes are known to brown after being cut, due to being exposed to oxygen. They are still safe to eat even if they change color, but you can preserve their color and keep them fresh with the proper storage technique. Transfer cut potatoes to a bowl or container, fill with water, and keep in the refrigerator until you are ready to use them. For best results, use within a day. For another storage technique, see my post on How to Freeze Potatoes.
