1. Preheat oven to 425 degrees.
2. In a large bowl toss the potatoes and the oil until evenly coated. Spread on one to two baking sheets so the fries are in a single layer.
3. Place in the oven and turn after 15 minutes. Cook until the fries become golden brown about another 10 to 15 minutes depending on how thick you sliced them.
4. Remove and sprinkle with salt, pepper and fresh chopped parsley.
