Should you boil potatoes before roasting? ›

Boil chunks of potato until they're just tender, toss them none-too-gently with fat (ideally beef drippings) to rough up their surface, then roast them until they're crisp and crackling. The boiling and roughing-up steps are the real keys.

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.

In a video online, Gordon explained: “For crispy roast potatoes, you can depend on them, my tip is to parboil them, leave them to steam dry, then sprinkle them with semolina or flour, and then give them a good roughing up.”

Just as overcrowding bacon or mushrooms in a saucepan causes disappointingly mushy results, placing potatoes too close to each other on a baking sheet will prevent them from crisping while they roast. Ovens are like saunas, blasting potatoes with dry, hot air.

Do I have to boil potatoes before roasting? Not necessary but this can help get the perfect consistency and crispiness. Make sure you boil them but leave them a bit al dente and they will crisp up perfectly in the oven.

Roast for 1hr until golden and crisp, and don't forget to turn them occasionally to ensure they cook evenly. Here's a few tricks to try to make them even more delicious. Sprinkle your parboiled potatoes with flour. This gives potatoes extra crunch.

Yes! Soak the potatoes in cold water to remove the excess starch from the outside of the potato. There are a few reasons why you want to remove that starch (it makes the potatoes burn, it keeps them from crisping up, it turns to sugar) but all you really need to remember is to soak them at least one hour.

"Placing [peeled and cut] potatoes in water helps prevent oxidation, which turns their exposed flesh brown," says Ronna Welsh, the author of The Nimble Cook and the owner and chef instructor at Purple Kale Kitchenworks in Brooklyn, N.Y. While oxidation won't make the potatoes unsafe to eat, it does change their flavor.

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).

Goose fat is one of the first choices for roast potatoes because first of all – it tastes nice! It has a really rich flavour compared to your more common vegetable oils. It's a bit like how cooking your roast potatoes in dripping from your turkey can add more flavour to your spuds too – they're both animal fats.

What kind of potatoes are best for roast? ›

The Best: Yukon Gold Potatoes

Their skin is thin, so they cook through fairly quickly, and they're just waxy enough to hold their shape. But if you've ever had a Yukon Gold potato, you know what really sets them apart is their buttery, creamy center, which lends itself so well to roasting.

To have a truly marvellous roast potato, one must simply let the potato dry completely after parboiling, before roasting in extremely hot fat. If you have two ovens you can cook them separately to your roast at a different temperature.

When the corn starch comes into contact with the hot oil, it forms a barrier that traps moisture within the potato while also developing a crunchy crust. This results in fries that are both tender on the inside and crispy on the outside, mimicking the texture of fries you might find in restaurants.

Also, be mindful of the oil. Potatoes can react like sponges; too much oil can make your potatoes appear to be soggy. Try placing oil in a spray bottle or using an aerosol to apply the oil to the potatoes. Lastly, ensure that the potatoes are dry before you add the oil.

Parboiling helps soften the potato insides before the roasting begins, so you won't be tempted to burn the outsides in exchange for less undercooked insides. Boil the potato chunks for eight to 10 minutes—they won't be fully cooked, but they'll be ready for the next step.

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.

Roasted potatoes can become soggy if the water content in the potato isn't fully cooked. Different potatoes have different water content percentages. Also, be mindful of the oil. Potatoes can react like sponges; too much oil can make your potatoes appear to be soggy.

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.
