The ideal temperature to fry French fries is between 325°F and 375°F. Most recipes suggest frying the potatoes twice at two different temperatures to achieve the perfect texture: first at a lower temperature of about 325°F to 375°F for about 5 to 12 minutes, depending on the recipe, to cook them without burning and give them a creamy texture. Then, the fries are removed from the oil and drained on paper towels for a few minutes before being fried again at a higher temperature of about 375°F for 2 to 4 minutes until golden brown and crispy. The second fry is considered a flash fry, and it is where the fries get their crispy exterior. It is important to fry the potatoes in small batches to avoid lowering the temperature of the oil and to shake off excess oil before serving.
