Preheat the oven to 400° F and line 2 large baking sheets with parchment paper.
It’s imperative the potatoes are completely dry after washing, you may want to air dry for a bit. Cut the potatoes in very thin slices - this is easiest using a mandoline if you have one.
In a large bowl, add the potato slices and drizzle with oil, mix to coat well. Add the spices, salt and pepper and toss to coat.
Place in a single layer on the prepared baking sheets. Bake until lightly browned and crisp, about 20 minutes, flipping halfway through.
