How long do potatoes need to boil for mashed potatoes? ›

Smaller potatoes (like red gold) will cook faster whole — about 15-20 minutes in boiling water. Larger potatoes (like russet) take a little more time — about 20-30 minutes.

You can use what you have on hand: Flour, cornstarch, or powdered milk are all solid options that are probably already in your pantry. Potato flour and potato starch would work as well. Stir in the thickening agent gradually, about a tablespoon at a time, until the potatoes have reached your desired consistency.

The first thing to know about freezing mashed potatoes is that the process may affect their texture. "The liquid absorbed by the potatoes while cooking will form ice crystals when they are frozen," says Martha's Vineyard- and Boston-based personal chef Carlos Montoya. "This may make them mushy, soggy, or grainy."

Rinsing potatoes helps remove excess starch, so it is recommended to rinse the potatoes before cooking. To ensure even more starch is out of the way, it's recommended that they even be quickly rinsed after boiling. We recommend using hot water for rinsing after boiling and cold water prior to boiling.

For good measure: Be careful not to overcook potatoes you plan to mash, because the starch cells will break down and create a sticky mash. Cook them just until a thin-bladed knife meets a bit of resistance. It is also important to drain the potatoes well after cooking to prevent gumminess.

Runny potatoes can happen for a few different reasons. Too much liquid: This is the most common reason. In the mashing process you may have added too much milk or broth. Boiled too long: Boiling your potatoes for too long can make them water-logged, which (you guessed it) can contribute to runny mashed potatoes.

Using a potato ricer or food mill breaks down cooked potatoes without overworking them, and from there you can gently fold in butter and milk for light and airy mashed potatoes, or you can control the level of starch manipulation to produce creamy pommes purée.

Whisk a little cornstarch into the warm potatoes, only a teaspoon at a time, until the potatoes thicken to your liking. The potatoes must be warm. You can also use tapioca starch or potato starch, although most cooks are less likely to have those products on hand.

The secret ingredient is just ice-cold water.

You soak the potatoes in iced water before they are cooked. This eliminates much of the starches in the potatoes, resulting in a super light and fluffy mash. It's also like when you make rice. The key to fluffy rice is to rinse off as much starch as possible.

Yes. Incredibly effective? You bet. This trick works because the instant mashed potatoes are naturally starchy and therefore are similar in form to other commonly used thickeners, such as cornstarch, only without the clumps.

Why do you put cold water in mashed potatoes? ›

Tips for the Best Mashed Potatoes

Start cooking the potatoes in cold water: This ensures that the potatoes cook evenly. Otherwise, if you start with hot or boiling water, the outsides of the potatoes cook and soften while the middles are still hard and crunchy.

Reheating Frozen Mashed Potatoes

Thaw them in the refrigerator overnight and reheat them on the stovetop. The other methods above can be used, but the stovetop creates the best texture for previously frozen mashed potatoes. If they seem dry, add a splash of dairy or butter while warming.

Potatoes cook best when they're boiled gently, not vigorously. Keep the lid off the pan when you're cooking them to monitor the boil. And when they're done, drain them well—extra liquid still clinging to the potatoes could make them soggy, too.

For how long to boil potatoes, you should place them in gently boiling water until tender, about 15 minutes for small red potatoes, new potatoes, or cubed large russet potatoes, and 20 to 25 minutes for quartered potatoes. Remember, the size of the potato pieces is a huge factor in how long to boil potatoes.

Cubed spuds will take around 15 minutes where larger chunks or whole new potatoes will be 20-25 minutes. To check when they are done, pierce the potatoes with the tip of a knife to see how much resistance there is. If it goes in easily, you're done!

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).

For most potato dishes it's important to add the potatoes to cold water and allow the water to come to a boil with the potatoes in the water. The potato starch can react as soon as it comes in contact with hot water, which will promote uneven cooking and mealy potatoes.
