Boiling your potatoes for a little bit before roasting helps make sure that you get that beautiful crisp crust on the outside. If you don't parboil your spuds, the outside skin will remain quite tough, meaning that whatever fat you use will not be able to get inside the cracks.
A general rule of thumb is to parboil potatoes until they are fork-tender but not falling apart, this can range anywhere from 15 minutes for small potatoes to 25-30 minutes for large whole potatoes.
Peel potatoes using a vegetable peeler. It's best to leave them whole, but you can go ahead and cube or dice them if you want — just don't slice them too thin. Fill a bowl with cool water, submerge the potatoes, then cover with plastic wrap. Store in the refrigerator overnight.
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.
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.
To make crispy roast potatoes, the temperature of the oven needs to be hot. If the oven is too hot the potatoes will burn before they crisp up. If the oven temperature is too cold your potatoes will not be crispy.
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.
While you can wait for the water to boil before adding in the potatoes, they will cook more evenly if you add them to the pot while the water is cold. Potatoes added to boiling water can turn out mushy on the outside and tough on the inside.
You can parboil whole potatoes or use a paring knife to cut them into equally-sized potato pieces, peeling if desired. Bring a saucepan 3/4 of the way full of clean, cold water to a boil. Add a pinch of salt to the water. Add cubed potatoes to the water and boil for 5 minutes.
Gently drain the potatoes in a colander, but do not shake them or ruffle them up – just leave them to drain and cool. Once there is no more steam coming off them, place on a tray in a single layer and put them in the fridge, uncovered, until ready to roast.
Can you parboil potatoes the day before roasting? Yes, to parboil the day before roasting, parboil, drain, rough the outside, and coat with oil the day before. Then cover them with plastic wrap and store them in the fridge until needed.
'Drain the boiled potatoes really well and leave them for a good long while afterwards to sit and cool. If you want to get ahead, why not boil them in advance, then toss in a little oil and store in the fridge until you're ready to roast them.
Parboiling is different from blanching in that after parboiling, you rinse the food under cold water, to stop it from cooking, then cook it further when other ingredients are ready, or you store it for later use. By contrast, blanching does not require a cold rinse or bath.
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.
Just give them a good rinse to remove any dirt and cut out any blemishes you see. 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.
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.
MYTH #2. MOST COOKING METHODS DESTROY THE NUTRIENTS IN POTATOES. While boiling potatoes does cause a small loss of water-soluble nutrients like vitamin C and vitamin B6, the white potato retains most, if not all, of its potassium and dietary fiber regardless of cooking method, such as baking, boiling, or frying.
First let's talk about why cut potatoes need to be immersed in water to begin with. The reason is to prevent the potatoes exposure to air, which causes dehydration, oxidation, and discoloration. Immersing cut potatoes will also help rinse off excess starch.
A good rule of thumb is to go with a 2-inch dice on the potatoes before boiling them. Cutting potatoes before boiling does aid in removing excess starch. Excess starch can make potatoes gummy or gluey. That said, cutting the potatoes too small can lead to too much water absorbing into the potatoes.
Parboiling potatoes before freezing them is not only a great way to get ahead, it also makes the potatoes extra crunchy when cooked. Roast from frozen while your meat is resting. Cut the potatoes into large, evenly-sized pieces and put into a large pan of cold salted water.
Many recipes for French Fries (as well as other potato recipes) recommend soaking the potatoes in cold water for thirty minutes. The rationale is that some of the starch is leached away and helps the texture of the potato, but this simply doesn't make any sense.
Try dunking your potato slices in salted water as the combination of water and salt keeps oxidation at bay. For every gallon of water, add about one teaspoon of salt to a large bowl or stockpot. Add the potatoes and then cover the bowl with plastic wrap.
