Steps
1. Preheat your oven to 220°C (425°F).
2. In a bowl, toss the half-cooked fries with olive oil, ensuring they are well-coated.
3. Sprinkle the grated Parmesan, oregano, garlic powder, salt, and pepper over the fries. Toss again to distribute evenly.
4. Spread the fries in a single layer on a baking sheet lined with parchment paper.
5. Bake for 15-20 minutes, or until golden brown and crispy, flipping halfway through.
6. Remove from the oven and garnish with fresh parsley if desired. Serve hot.
