First, peel your potatoes with a knife or vegetable peeler. (Peeling your potatoes is an optional step, but it's the way that my family prefers.)
Second, wash your potatoes in cool water. (Do not submerge them)
Third, cut potatoes into medium-thin strips. (You can see how I do this best in my cooking video on YouTube, but I'm going to explain it step by step below.)
First, cut the ends of the potatoes off and cut the potato in half and lay cut side down.
Second, cut the halves into half inch pieces.
Third, remove the end pieces and turn the cut potato on its side.
Next, cut the potato two more times to make the perfect fries.
Next, pour oil into a cast iron skillet over medium-high heat.
Then, place the fries in a single layer in the oil and fry in batches until they begin to get golden brown and crispy.
Take them out of the oil and drain on the paper towel lined plate, cutting board, or baking sheet.
Finally, immediately sprinkle the fries with salt and pepper, serve with your favorite dipping sauce, and enjoy!
