Preheat the oven to 400°F (200°C).
Line a baking sheet with parchment paper.
In a large bowl, toss the potato rounds with olive oil.
In a separate bowl, mix Parmesan cheese, garlic powder, paprika, salt, and black pepper.
Coat the potato slices with the Parmesan mixture and place them on the baking sheet.
Bake for 25-30 minutes, flipping halfway through, until golden and crispy.
Garnish with fresh parsley and serve warm.
