In a large pot, add about 3 inches of oil and heat to 300 degrees.
Cook half the potatoes for 4-5 minutes to cook through, but not brown. Transfer to a new paper towel-lined baking sheet. Repeat with remaining potatoes.
Increase the heat of the oil to 400 degrees. Fry the potatoes, working in batches, for about 4-6 minutes, or until crisp and golden brown. Drain on paper towel lined baking sheets. Salt the fries as soon as they come out of the oil.
