Preheat oven to 400F.

Cut the potatoes into thick even-sized french fries. Rinse them under cold running water and then dry well on a clean dish towel. Put in a bowl, add the oil and toss together until coated.

Spread the fries on baking sheet and cook in the oven for 40-45 mins turning once, until golden. Add salt & pepper to taste and serve hot.
