Boiling potatoes is neither exciting nor particularly sexy, as far as cooking skills go, but it is quite handy! All our favorite dishes from potato salad for a summer cookout to mashed potatoes for the Thanksgiving table start with — oh yes! — boiling a pot of potatoes.
Whether you’re boiling your first potato tonight or wonder if you’ve been doing it right, here’s a step-by-step guide showing you exactly how to boil potatoes.
How Long to Boil Potatoes?
Generally, you want to boil potatoes for 10 to 20 minutes. That’s how long it takes to cook them evenly all the way through. Here’s how long to boil potatoes specifically for mashed potatoes.
Whole potatoes will take longer than cut-up or cubed potatoes, so it’s important to test your potatoes for doneness. When they are ready you should be able to easily pierce them with a fork all the way through.
You’ll want to boil potatoes any time you don’t want them to dry out (as they can when baked in the oven). So it’s a cooking method ideal for mashed potatoes or potato salad. Boiled potatoes on their own can also make a quick side dish.
The Best Potatoes to Boil: Waxy, Starchy or All Purpose?
Waxy or all-purpose potatoes are the best candidates for boiling. They hold their shape when boiled and have a nice creamy texture once cooked.
They are also usually smaller — usually no bigger than your fist — and thin-skinned, so they cook more quickly. Waxy and all-purpose potatoes might be red or golden or purple; take a look at this guide to sixteen kinds of potatoes to see what kind you’re dealing with.
You can also boil starchy potatoes like Russets — I have friends who swear by mashed potatoes made with Russets! Starchy potatoes tend to fall apart or become water-logged when boiled, so I recommend boiling them whole instead of cubed.
Whole Potatoes or Cubed? Skins On or Peeled?
You can boil potatoes either whole or cubed — both ways work fine. In either case, the key is to make sure the whole potatoes or cubed potatoes are roughly the same size. This way, they will all cook at the same rate.
If you’re boiling whole potatoes, you might need to remove small potatoes from the water a little sooner and let larger potatoes cook a little longer.

Prepare the potatoes. Scrub 3 pounds waxy or all-purpose potatoes clean. If desired, cut the potatoes into large, evenly-sized cubes.
Transfer the potatoes to a saucepan and cover with cold water. Transfer the potatoes to a saucepan or pot large enough to hold all the potatoes with some room on top. Cover the potatoes with an inch or two of cold water. Starting the potatoes in cold water helps them cook more evenly.
Stir in the salt. Stir 1 teaspoon of salt into the water until dissolved.
Bring to a boil, then reduce to a simmer. Place the pot over medium-high heat and bring to a boil. Once boiling, reduce the heat to a bare simmer. Do not cover. (Covering changes the environment in the pot and can make the potatoes turn mushy.)
Check the potatoes after 5 minutes. Cubed potatoes will cook more quickly than whole potatoes; smaller potatoes will cook more quickly than larger potatoes. Begin checking the potatoes after around 5 minutes of simmering; most potatoes will be done in 10 to 20 minutes.
The potatoes are done when tender. The potatoes are done when they are tender all the way through. You can test this by poking the potato with a fork, paring knife, or skewer. If the utensil slides easily all the way to the center, the potatoes are done.
Drain the potatoes. Drain cubed potatoes in a strainer or lift whole potatoes out with a slotted spoon. If your recipe calls for cold potatoes, you can run the potatoes under cold water or dunk them in an ice water bath to cool them down more quickly.
Recipe Notes
Storage: Cooked potatoes can be refrigerated in an airtight container for up to 5 days.
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.
Dense potatoes don't absorb seasonings easily, so you'll need to salt the water liberally so that the water the potatoes do drink up also carries in seasoning. And because potatoes are so timid in flavor, they need that salt to bring them out of their shells. Pour some salt in, then keep going.
In general small or cubed potatoes will take about 10 to 15 minutes to boil, while larger, whole potatoes will take between 20 to 25 minutes. To check potatoes for doneness, insert a knife into one.
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.
It's really the best way. Microwaving sweet potatoes cuts down cook time by 45 to 55 minutes, and, according to a 2018 study, helps maintain the potato's nutritional value. All cooking methods cause foods to lose some of their nutrients, but the quicker your potato cooks, the more nutrients it will retain.
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.
This comes down to personal preference. Potato skins have great potato flavor. Not only do they add flavor, but some really like the texture of potato skins in mashed potatoes. If, however, you are looking for a super-light and fluffy mash with no color contrast, then you may want to consider peeling the potatoes.
We suspect that the pan may have dried out a little too quickly, meaning that there was not enough liquid for the potatoes to cook in and this may have caused them to become hard. Pan dimensions and materials vary a lot and a larger pan, or one with a very shallow lip, could cause the liquid to evaporate more quickly.
In a large pot, add potatoes, 1 tablespoon salt, and cold water to cover by 1 inch. Bring to a boil, reduce heat to medium, and cook uncovered until potatoes are tender and can easily be pierced by a knife, about 10 to 15 minutes (20 to 25 minutes for larger potatoes).
How Do You Know When Potatoes Are Boiled? A good indicator of when a potato is done boiling is if you can pierce it with a fork. You want the potatoes to be tender all the way through, with a fork easily sliding through to the center. If you get resistance, boil for another few minutes and check again.
If you overcook them they disintegrate and your potatoes will be soupy. The specific cooking time depends on the size of your potato: a perfectly cooked piece of potato should give no resistance when cut with a knife, but shouldn't crumble into a million pieces.
Place the pot over medium-high heat and bring to a boil. Once boiling, reduce the heat to a bare simmer. Do not cover. (Covering changes the environment in the pot and can make the potatoes turn mushy.)
Once cooked (whole or cut) potatoes can be stored in water (with or without vinegar) without becoming discolored or mushy. But, water storage isn't necessary. Refrigerate the boiled potatoes in a sealed container and use within a couple of days.
Drop a whole russet into the pot and by the time the outside has cooked through, the inside will still be raw. Larger potatoes should be cubed to ensure they cook evenly (peeled first if desired). Smaller potatoes tend to have thin skins and can be boiled whole, no peeling required.
Baking a potato is the best way to prepare it, as baking, or microwaving, a potato causes the lowest amount of nutrients to be lost, she said. The next-healthiest way to cook a potato is through steaming, which causes less nutrient loss than boiling.
According to USDA data, microwaving potatoes is the best way to retain its nutritional value, boiling potatoes causes the most nutrient loss, and frying adds fat and extra calories.
It is still possible to benefit from these nutrients if you consume the liquid, for example, by turning the potato and the liquid into a soup. Alternative cooking methods such as grilling, roasting, steaming, stir-frying or microwaving generally preserve a greater amount of vitamins and other nutrients.
The steam gets hotter than boiling in water, allowing the potatoes to cook faster. After about 15-20 minutes the potatoes should be fork-tender and ready for mashed potatoes.
