What oil does Jamie Oliver use for roast potatoes? ›

You want to use an oil with a mild flavour for your roasties. We prefer olive oil, but you can opt for vegetable, canola or grapeseed oils instead.

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.

The RSVP International Hasselback Potato Guide is really the key to hassle-free Hasselback-ing. Once I wash my potato, I pierce it with the guide and use my knife and the guide's prongs to cut the potato, over and over again, going from right to left.

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.

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.

If you're pressed for time, the slightly sticky, cut potatoes should be soaked for a minimum of 15 minutes. However, a longer soak time may allow more starch to be removed. So, if you can prep the fries ahead of time, a few hours of soaking can help make them even crispier.

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.

For Gordon's roast potato recipe you'll need: 1.2kg floury potatoes, such as Maris Piper or King Edward.

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.

The main reasons to cut the potatoes and pre-soak in water are: To allow the excess starches and sugars to be removed from the outer surface of the fry strips AND to keep the potatoes from browning prematurely from exposure to air. Covering in water helps the potato from turning a dark color.

What does cornstarch do to potatoes? ›

After closely inspecting the brand of frozen French fries I often buy, I realized that they are coated in a blend of starches to help crisp them up. So, I decided to give the method a shot with roasted potatoes. And it turns out, coating the potatoes with cornstarch is the secret to super crispy roasted potatoes!

But despite using steam power, a slow cooker can also make the crispiest potatoes this side of your oven. One insider hack is to parboil the potatoes for about 10 minutes before plain them in the slow cooker. By parboiling, you'll get a head start on cooking them by ensuring the potato flesh is cooked.

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.”
