How to Store Peeled Potatoes: 9 Steps

Potatoes are always a great addition to the dinner table, but sometimes it takes too long to peel, wash and slice vegetables every time you want to eat them. Save time on future meals by preparing all the work in advance and putting the peeled potatoes in a bowl of water. Add a little mild acid, such as lemon juice or vinegar, to slow browning. Peeled potatoes are good for an hour or two when left on the table and about 24 hours in the fridge.


Part 1 of 2: Storing Potatoes in Water

Store Peeled Potatoes Step 1

Step 1. Wash the peeled potatoes in cold water

Once you have removed all the thick husk of the vegetable, place it under cold running water. When the water comes out clean, leave the potatoes in a layer of paper towels and pat them dry.

  • If you're making a large batch, peel everything first, then transfer the vegetables to a colander and wash them all together.
  • When peeling the potato, the liquid starch inside is exposed to the air and begins to turn the vegetable dark pink or brown. Give it a quick wash to remove starch and slow down the discoloration process.

Step 2. Cut the potatoes into smaller pieces if desired

At this point, you have the option of chopping or slicing them the way the recipe calls for. This greatly reduces preparation and cooking time later. If you don't need it, it's okay to leave them whole. They will last the same time.

  • Use a very sharp knife. Dull knives cause unnecessary damage to the vegetable, releasing more enzymes that cause decomposition.
  • Cut them into 2-inch cubes to make mashed potatoes, or cut them into 3-inch slices for dishes like homemade potato chips or au gratin.
  • The smaller the size, the faster the vegetable will absorb water. So it's best to wait until the last minute to prepare potatoes from dishes like hashbrowns, potato chips or vegetable mixes.

Step 3. Fill a large bowl with cold water

Choose a bowl large enough to hold all the potatoes you are preparing, eliminating the need to place multiple containers on the table or in the fridge. Half fill with water, leaving enough space for the amount of potatoes to be added.

  • Avoid overfilling the bowl as it may overflow when you add the vegetables.
  • If making a puree, pour the water directly into the pan instead of the bowl. When you're ready to prepare dinner, take the pan to the stove and boil the water.

Step 4. Add some lemon juice or vinegar

Squeeze a few drops of an acidic ingredient into the water, such as citrus fruit juice or distilled white vinegar, and mix until completely distributed. There is no correct amount to use, but a good measure is usually a tablespoon. For a two to five liter container, use half to two tablespoons.

The sour ingredient will not change the taste of the baked potatoes

Step 5. Place the potatoes in the bowl of water

There should be enough water to completely cover all the vegetables. Once they are submerged, they will not have contact with the oxygen in the environment, which prevents decomposition.

Potatoes give off gas when they're decomposing, so if they're floating near the surface of the water, it could be a sign they're not as fresh as you thought

Step 1. Cover the bowl

A closed container is ideal for storage. If one is missing, stretch a piece of film or aluminum foil over the mouth of the bowl and press the ends well into the edges to seal well. This will protect the contents from the air and minimize the chance of accidental splashing.

Remove as much air as possible from the container before closing it

Step 2. Use potatoes stored at room temperature within an hour or two

There is no need to refrigerate them if you are going to cook them soon. Just leave the bowl on the kitchen table and remove the potatoes from the water when you need them. They shouldn't have too much discoloration after a short time.

Storage at room temperature can be useful if you prefer to prepare all the ingredients at once before starting to cook

Step 3. Refrigerate potatoes for up to 14 hours

If you are not going to cook them right away, they will need to be refrigerated. Place the bowl on one of the middle shelves of the refrigerator and leave it overnight. Drain the water from the bowl the next day if they are to be prepared in the oven or in a skillet.

Storing the vegetable wet for more than a day can cause it to shrive up quite badly, which affects its flavor and texture

Step 4. Change the water if necessary

Sometimes the water used for storage starts to show signs of discoloration instead of the potatoes themselves. When this happens, just drain the potatoes in a colander, return the vegetables to the bowl and add fresh water.

  • If you leave them in dirty water, the potatoes will absorb the same enzymes that cause browning under normal conditions.
  • Most enzymes are released within the first few hours, so you won't need to change the water more than once.


  • Use a vegetable peeler to remove the stubborn pieces of skin that remain on the potato before soaking it.
  • Peel, slice and store potatoes a day in advance to start preparing a big meal for the holiday season.
  • For dishes that need a crunchy texture (such as very thin French fries), it is recommended to cut vegetables immediately before cooking them.
  • By washing the peeled potatoes and changing the storage water, you can make them last for up to three days.
