Place the potato slices in a gallon freezer bag and drizzle the oil, salt, and pepper over them.
Close up the bag and shake to coat the slices as evenly as possible.
Bake at 450° for about 20 minutes or until tender and lightly browned, turning once.
You can use this recipe with russet potatoes as well, but I usually leave out the hot pepper and instead add some non-salt seasoning or paprika.
Also, we like our fries a bit on the crispy side so I tend to roast them a bit longer, depending on the thickness of the slices.
