1Heat the oven to 400 degrees F.
2Cut each potato lengthwise, then slice into 1/2-inch strips. Turn the potatoes into a large bowl, toss with the oil to thoroughly coat, then toss in the salt.
3Spread the potatoes on an ungreased baking sheet about 1/4 inch apart (they shouldn’t touch).
4Bake about 15 minutes, then turn them with a spatula and continue baking, turning every 5 minutes so that they don’t stick, but brown evenly on all sides, about 25 to 30 minutes total.
