FAQs

Why are my roast potatoes never crispy? ›

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.

Soaking the sliced potatoes in water helps to draw out some of the starch from the middle of the potato, resulting in a sturdier, crispier French fry.

Parboiling the potatoes in alkaline water breaks down their surfaces, creating tons of starchy slurry for added surface area and crunch.

I first came across this trick from a post on Serious Eats – baking soda creates an alkaline environment for the potatoes to boil in, which maximises the starch so our roast potatoes are extra crispy! Swish the potatoes around your colander after boiling.

If you're roasting potatoes start-to-finish in the oven, you should always salt them after cooking. This is to avoid drawing out moisture while they cook and making the outer layer leathery.

In addition, this simple step will help potatoes cook more evenly. This is because soaking potatoes removes excess starch, which can build up and create a gummy and uneven texture. You can achieve the best results if you soak your potatoes, strain them, and then soak them again in fresh water.

Should you rinse starch off potatoes before roasting? ›

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.

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.

Give them a cold water bath: Once your potatoes are chopped, toss them into a large bowl. Then cover the potatoes completely with cold water and let them soak for at least 30 minutes (or up to overnight). This will help to rinse off the excess starch and help the potatoes crisp up beautifully in the oven.

If you like your roasted potatoes extra crispy, you may want to have a bowl of ice water on standby during the cooking process. 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.

Heat your oven to 400 degrees, spread potatoes on a sheet pan and cover them in tin foil. Re-roast them until they're warm all the way through, about 10-15 minutes. Remove the cover for another five to add crispiness.

Old Potatoes: Very old or stored potatoes can become starchy and may not soften as well during cooking. It's best to use fresh, firm potatoes. Acidic Ingredients: If your soup contained highly acidic ingredients (e.g., tomatoes), it could have affected the texture of the potatoes.

To achieve the driest potatoes possible, let them simmer in well-salted water for 12 to 15 minutes before roasting. Be sure to drain and let them cool completely before moving on to allow all that steam to escape.

Simply tossing raw potatoes into the pan before roasting will guarantee tough results because the high water content will steam out over the course of a long cooking time. "You feel more like you're eating the skin, because the structure just collapses inside," says Hanson. "It also gets too hard.
