Preheat oven to 400°F. Remove oven racks & spray them with oil.
Wash potatoes & slice them lengthwise into sticks 1/2" thick or
crosswise into rounds 1/3" thick. Transfer to a baking pan & spray
well with oil. Add seasonings & toss to coat. Place the rounds in a
single layer on the oven racks. Place the racks in the centre of
the oven. Bake until the potatoes are tender, with a deep,
golden-brown crust, about 20 to 25 minutes. Serve piping hot.
