Preheat oven to 375 degrees. Cut potatoes into 1/8-inch thick slices by using either the slicing disc of a food processor, mandoline slicer, or by hand. Place potato slices in a large bowl. Add olive oil, salt, and pepper, and stir well to coat.
Spread in a single layer on two large baking sheets. Bake 15 minutes. Flip potatoes, and cook another 10-15 minutes, or until chips are crispy.
