Crispiest: Place the oil in a deep roasting pan and place it in a hot oven for 10 minutes until shimmery. Carefully remove the roasting pan, place on a heat proof surface and use a pair of tongs to place the potatoes in the hot oil, turning to coat, then roast the potatoes in the oven.
Crispier: In a small pan, heat up the oil over medium heat. When hot and shimmer, very carefully pour it into it to a deep roasting pan. Use a pair of tongs to transfer the potatoes over to the hot oil and toss to coat then roast in the oven.
Crispy: Place the potatoes in a roasting pan, drizzle on the oil and then use a pair of tongs to coat each potato then roast in the oven.
My favorite way to achieve ultra crispy roasted potatoes
My favorite way of getting super crispy potatoes without the scariness of pulling a hot pan of oil out of the oven is a combination of numbers 2 and 3. I like to get my biggest cast iron, and heat it up with the oil over medium high on the stove. When it’s hot and shimmery, I carefully use a pair of tongs to add the fluffed up potatoes in, tossing, while the pan is still on the heat. Once everything is evenly coated in oilm I pop the whole thing into the preheated oven where everything gets super crispy and crunchy. The key to crispy potatoes is the hot oil and the hot pan in combination, so this is my number one choice for both, as well as safety.
