Coat a cooking sheet with cooking spray. Preheat oven to 350.
Cut potatoes into slices or strips. Place in a plastic bag with the olive oil (enough to coat the potatoes) and the seasoning.
Place potatoes in a single layer on the prepared cooking sheet.
Place in oven and bake until potatoes are tender and golden brown. Turn the potatoes midway. For a crispier potato, place under broiler for a few minutes at the end of the cooking time.
