FAQs

Why are my potatoes not getting crispy in the oven? ›

If roasted potatoes lack their crunchy sheen, overcrowding is usually the culprit. 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.

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.

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.

Keep potatoes crisp in a warm oven if you're serving them in 1-2 hours. If there is a slight wait before everyone eats, don't cover the crispy potatoes—this traps steam which will make the potatoes soggy. Just keep them in the oven, but turn the temperature to the lowest setting.

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.

Neutral, low-cost oil such as vegetable oil, canola oil, safflower oil, peanut oil, corn oil, coconut oil, avocado oil, etc., work well for roasting. These oils have a high smoke point, allowing the potatoes to get very hot to achieve maximum crispiness.

Parboiling potatoes allows you to get crispy roasted potatoes that have a nice crust on the outside while being soft on the inside.

Meanwhile, the alkaline water helps the exteriors of the potatoes break down more, creating much more of the starchy slurry that leads to an extra-crisp exterior. About a half teaspoon of baking soda for two quarts of water was the right amount.

Some people suggest that you leave your boiled spuds to dry overnight before you roast. This is because the best crunch is the result of the driest potato hitting the hot fat.

"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.

Should you rinse starch off potatoes before roasting? ›

For roasting, you may skip blanching, if time is of the essence, and simply soak wedged potatoes for at least 5 minutes, but the longer they soak, the more starch you will release. After the potatoes have soaked, rinse them in a colander before patting dry with paper towels.

Dunk the Potatoes in a Saltwater Solution

This step is extremely important because it seasons the skin and encourages it to dry and crisp in the oven.

Preheat the fat. While the potatoes parboil, add the oil or butter to the roasting pan, transfer it to the warm oven, and heat it for about 5 minutes before adding the potatoes. This allows the outside of the potatoes to crisp up nicely and not just absorb the cold fat when you put them in the oven.

A: This sure sounds a lot like potatoes that have been stored too long, in too cold of an environment before cooking. When potatoes are held below 41°F for too long a period, the starches convert to sugar and it changes the cooking chemistry.

Soaking your sliced potatoes in the ice water before roasting them in the oven can draw out extra starch, allowing the spuds to cook up extra crunchy on the outside.

Potatoes need to cook all the way through, and the best way for that to happen is to make sure the hot air can get to the potato from all sides. If a potato bakes with one side touching a sheet pan, you'll get a hard spot and possibly uneven cooking.

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.

If the potato is hard, bake it a little longer. Don't exceed the recommended cooking time because potatoes will continue to cook after they're removed from the oven and the skin will get dry. "Another common mistake is letting the potato rest or cool before cutting.

Overcrowding may be the main reason your potatoes aren't crisping up in the oven, but there are plenty of other tips and hacks you can employ to reap the benefits of roasting, starting with choosing the best type of potatoes.
