FAQs

Why does vinegar make potatoes crispy? ›

The acid in the vinegar can also help to slightly break down the surface of the potatoes, aiding in the development of a crispier texture during frying. Additionally, the vinegar can contribute to a golden-brown color on the exterior of the fries.

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.

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.

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.

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.

In his recipe, López-Alt shares his secret for perfectly cooked potatoes every time: Adding vinegar to the water (specifically, 1 tablespoon of vinegar per 1 quart of water) prevents overcooking.

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.

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.

Use parchment paper– non stick foil, or baking sheets will not do the trick. Parchment paper allows the potatoes to roast without sticking!

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.

What potatoes are best for roasting? ›

Russet potatoes will produce crisper crusts and fluffier centers. Yukon Golds will be slightly less crisp and have creamier centers, with a darker color and deeper flavor. You can also use a mix of the two. The potatoes should be cut into very large chunks, at least 2 to 3 inches or so.

Arrange cooked potatoes on a baking sheet in a single layer (if desired, line with parchment paper). Cover pan with aluminum foil and place in hot oven. Cook for 20 minutes, and then remove foil and let them go for another 5-10 minutes or until they are the crispy potatoes you are looking for.

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.

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.

Vinegar causes the potatoes to form a thin crust that further helps in retaining their shape. Vinegar increases the acid pH levels of water which further helps the potato just like when you add a little salt to the water while boiling eggs.

Acid prevents potatoes from softening

Hemicellulose, the carbohydrate that makes up potatoes, softens when cooked, but when you add an acid like vinegar, the hemicellulose will remain solid instead.

Add lemon juice or vinegar

Lowering the pH of the potato helps fight off oxidation. Just like you might use a squirt of lime juice to keep guacamole from browning, a bit of lemon juice or white vinegar in the bowl with the potatoes will ward off gray hues.

But malt vinegar has a way of zinging up fries and other fried foods in a way that ketchup, despite its vinegar base, simply doesn't. It works better on British-style "chips," which are wider and better able to absorb the condiment.
