Preheat the oven to 400°F. Line a large baking tray with parchment paper and set aside. Cut the potatoes into 1/4-inch slices and add to a large ziplock bag.
In a small bowl, whisk together olive oil and spices. Pour the spice mixture over the potatoes and seal the bag. Use your hands to move the potatoes around in the bag, coating completely with the spice mixture.
Pour the potatoes onto the baking sheet and space them out as much as possible, making a single layer.
Bake for 40-45 minutes, or until the potatoes are fork-tender and golden brown. For more crispy potatoes, turn the broiler on for 2-3 minutes, watching closely so they don't burn.

Make sure to break up any potato slices that are stuck together, so they don't bake in big pieces.
If your slices are smaller or larger, you may have to adjust the cooking time up or down accordingly.
Bake with some extra garlic powder, then top with parmesan cheese and black pepper as soon as they come out of the oven for a garlic parmesan flavor.
