Potatoes are always a welcome addition to the dinner table, but it can get time-consuming to peel, wash, and slice them every time you want to eat them. Save time putting together future meals by doing your prep work in advance, then place the peeled potatoes in a bowl of water. Add a splash of mild acid, like lemon juice or vinegar, to stave off browning. Freshly-peeled potatoes should keep for 1-2 hours when left to sit out on the countertop, or about 24 hours in the refrigerator.

    As soon as you’ve removed the thick skin from the outside of the potatoes, hold them under a stream of cold water. Once the water runs clear, set the potatoes aside on a layer of paper towels and gently pat them dry. [1]
    • If you’re preparing a large batch, take care of all your peeling at once, then transfer the potatoes to a strainer and rinse them together.
    • When you peel a potato , the liquid starches inside are exposed to air and quickly begin turning the potato a dark pink or brown hue. Giving them a quick rinse washes away excess starches to slow the discoloration process. [2]

    Cut the potatoes to a smaller size if desired. At this point, you have the option of chopping or slicing the potatoes into whatever form a particular recipe calls for. This can drastically cut down on prep and cooking time later. Otherwise, it’s okay to leave them whole. They’ll keep for about the same amount of time either way. [3]
    • Use a knife that’s nice and sharp. Dull knives do unnecessary damage to the potato, releasing more of the enzymes that lead to spoilage. [4]
    • Dice the potatoes into 1.5–2 inches (3.8–5.1 cm) cubes for mashed potatoes, or slice them into 1 ⁄ 2 inch (1.3 cm) slices for dishes like homemade potato chips or potatoes au gratin.
    • The smaller the potatoes are cut, the faster they’ll take on water. For this reason, it may be best to wait right up to the minute to prep spuds for dishes like hashbrowns, home fries, or vegetable medleys.

    Choose a bowl big enough to hold all of the potatoes you’re preparing so you don’t have multiple containers sitting around on the countertop or in the refrigerator. Add water to about the halfway point, making sure to leave adequate room for the quantity of potatoes you’re working with. [5]
    • Avoid overfilling the bowl, or it may overflow when you add the potatoes.
    • If mashed potatoes are on the menu, run the water directly into a cooking pot instead of a bowl. When you’re ready to get dinner going, you can simply place the pot on the stovetop and heat the water to a boil.

    Squeeze a few drops of an acidic ingredient like citrus or distilled white vinegar into the water and stir until it’s completely distributed. There’s no single correct amount of acid to use, but a good general measurement is approximately 1 tablespoon (14.8 ml) for every gallon of water. For a standard 2–5 US-quart (2,000–5,000 ml) mixing bowl, this will be about ½-1¼ tablespoon. [6]
    • The acidic component shouldn’t impact the flavor of the cooked potatoes.
  5. Watermark wikiHow to Store Peeled Potatoes
    Make sure there’s enough water in the bowl to cover the potatoes entirely. Once they’re submerged, they’ll be out of reach of the oxygen in the surrounding environment, which will keep them from going bad. [7]
    • Potatoes release gases as they decompose, so if they’re floating near the surface of the water, it may be a sign that they’re not as fresh as you thought.

Keeping the Potatoes Fresh

  1. Watermark wikiHow to Store Peeled Potatoes
    An airtight storage container with a locking lid will provide the best results. If that's not an option, stretch a sheet of plastic wrap or a piece of aluminum foil over the mouth of the bowl and press the edges down over the rim to create a seal. This will keep the contents off-limits from the air and minimize the chances of an accidental spill. [8]
    • Squeeze as much air out of the storage container as you can before sealing it up.
  2. Watermark wikiHow to Store Peeled Potatoes
    There’s no need to refrigerate the potatoes if you’re going to be cooking with them. Just leave the bowl out on the countertop and remove the potatoes from the water when you need them. They shouldn’t display much discoloration, if any, after such a short time.
    • Room temperature storage can be useful if you prefer to prep all your ingredients at one time before before moving onto cooking.
  3. Watermark wikiHow to Store Peeled Potatoes
    If you’re not going to be cooking the potatoes right away, it will be necessary to keep them chilled. Place the bowl on one of the middle shelves in the refrigerator and leave it there overnight. Be sure to drain the water from the potatoes the following day if they’re destined for the oven or frying pan. [9]
    • Wet-storing potatoes for longer than about a day can cause them to become water-logged, which may affect their flavor or texture.
  4. Watermark wikiHow to Store Peeled Potatoes
    Sometimes, the water you’re using for storage will begin to show signs of discoloration rather than the potatoes themselves. When this happens, simply drain the bowl into a strainer, then return the potatoes to the original bowl and add fresh water. [10]
    • If left to sit in the dirty water, the potatoes will be soaking in the same enzymes that cause them to turn brown under normal conditions.
    • Most of the enzymes will leach out in the first couple of hours, so you shouldn’t have to change the water more than once.

  • Question
    I was wondering if something called Fruit-Fresh (produce protector) would work to keep them from turning brown?
    Community Answer
    If you'd like to avoid chemical preservatives, simply covering the peeled potatoes in water and in the fridge will keep them from turning brown. You wouldn't want leave them more than 2 - 3 days before cooking, though. Just an added option: change out the water daily. Soaking potatoes in water removes a lot of the starch, and that might be a consideration, depending on what you're making.

    Can you use Alum in your water to soak overnight in the refrigerator?
    Maggie Peterson
    Community Answer
    No, alum is not recommended for soaking peeled potatoes. Alum is not the safest food additive, and it is rarely used in food preservation. It is toxic in large doses.

      • For dishes where a crisp texture is key (like latkes or thinly-sliced French fries), it’s best to just hold off on cutting your potatoes until right before you cook them .

      Warnings

      • Avoid storing shredded potatoes in water. Since the pieces are so small, they’ll quickly absorb water and lose their crispness.
