Creating these delicious Parmesan Potato Stacks is simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
2. Prepare Potatoes: Wash and peel the potatoes. Using a mandoline or sharp knife, slice the potatoes into thin rounds (about 1/8 inch thick).
3. Mix Seasoning: In a large bowl, combine the grated Parmesan cheese, garlic powder, onion powder, salt, and black pepper.
4. Layer the Potatoes: Take a slice of potato and dip it into the olive oil, then coat it with the cheese mixture. Layer the slices vertically in a stack, repeating the process until you have a small tower.
5. Place on Baking Sheet: Arrange the stacks on the prepared baking sheet, leaving space between each stack.
6. Bake: Bake in the preheated oven for 30-35 minutes or until the tops are golden brown and crispy.
7. Check for Doneness: The potatoes should be tender inside. You can test this by inserting a fork into the center of a stack.
8. Garnish: Once baked, remove from the oven and let cool slightly. Garnish with fresh herbs if desired.
9. Serve: Carefully transfer the stacks to a serving platter using a spatula.

These simple steps will guide you in creating these incredible Parmesan Potato Stacks effortlessly.
