Can You Peel and Cut Potatoes Ahead of Time? ›

No matter which way you slice (er, peel?) it. The short answer is yes. You can absolutely peel potatoes ahead of time.

While you can prepare peeled potatoes ahead of time, it's important to realize there are some caveats. For instance, this process works exceptionally well for whole or larger cubed potatoes — but not so well for shredded or finely cut potatoes. The larger the potato pieces, the longer they can hang out in water.

How long can peeled and cut potatoes sit in water before cooking, before they begin taking on too much water? A: We usually recommend no more than 24 hours. You can keep the potatoes from absorbing the water by making sure the water is not salted, and is chilled (you can even add ice to the water).

Why use salt water for soaking potatoes? There's moisture naturally found in potatoes, and moisture is drawn to higher concentrations of salt. (This is a process called osmosis.) So, if you put the potatoes in a salt water bath, that will help draw out some of their moisture, resulting in crispier fries.

Wash the potatoes well when you're ready to cook them. Don't store potatoes in the fridge. Raw potatoes have lots of starches, and the cold temperatures can turn the starches into sugars. This can make your potatoes turn sweeter and darker during cooking.

As soon as you leave out peeled or cut potatoes, the oxidation process begins and the potatoes turn brown. Oxidation is a chemical reaction between the starches and sugars in the potato and the air that does not impact the edibility of the potato but does change its color.

The best (and most popular) way to keep cut potatoes from turning brown is to completely submerge them in a bowl of water. Store the water-covered potatoes in a bowl in the refrigerator until you're ready to use them, up to one day in advance.

Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.

Large sprouts, growths, and roots will not only be unpleasant to eat, but, in the worst cases, can also make you really sick. Symptoms of poisoning from solanine (the specific type of natural toxin found in spoiled potatoes) include everything from a fever and headache to a severely upset stomach or abdominal pain.

Where is the best place to store potatoes? ›

The key is to store potatoes in a cool dry place, like in the cabinet of a pantry, in a paper bag or cardboard box. It's important to keep potatoes at the cool, ideal temperature (but not, surprisingly, the fridge) to prevent them from turning green, getting soft spots, or pre-maturely sprouting.

You absolutely can freeze potatoes, and you should if you have an excess of spuds. But there's one important thing to remember: You should really only freeze cooked or partially cooked potatoes, as raw potatoes contain a lot of water. This water freezes and, when thawed, makes the potatoes mushy and grainy.

Soak them in water

Store the water-covered potatoes in a bowl in the refrigerator until you're ready to use them, up to one day in advance. For a little extra insurance, add something acidic to the water, such as a splash of vinegar or fresh lemon juice. This will help slow the oxidation process even more.

If you're pressed for time, the slightly sticky, cut potatoes should be soaked for a minimum of 15 minutes. However, a longer soak time may allow more starch to be removed. So, if you can prep the fries ahead of time, a few hours of soaking can help make them even crispier.

Some people may prefer to peel the potatoes before boiling, but we would recommend you leave the skins on. This ensures that the nutrients and flavours are not lost during cooking and you get all those lovely vitamins too.

You can freeze potatoes with or without the peel.
