Add your fries to the 300°F oil and cook for 5-8 minutes, just until potatoes are starting to cook but are not yet browned. Remove potatoes from oil and scatter on a wire rack. Increase oil temperature to 375°F Once oil is heated to that temperature, return the potatoes to the fryer and cook until potatoes are golden brown. Remove to a paper towel-lined bowl.
