Steps
1. Preheat the oven to 400°F (200°C).
2. Wash and peel the potato, then slice it into 1/4-inch thick medallions.
3. In a bowl, mix together the olive oil, rosemary, thyme, garlic powder, salt, and pepper.
4. Toss the potato medallions in the herb mixture until they are evenly coated.
5. Arrange the medallions on a baking sheet lined with parchment paper, ensuring they are not overlapping.
6. If using, sprinkle the grated Parmesan cheese over the medallions.
7. Bake in the preheated oven for 25-30 minutes, or until golden and crispy, flipping halfway through.
8. Serve hot as a delicious main dish.
