Preheat oven to 425°F. Line a baking sheet with parchment paper.
Boil potatoes in salted water until fork-tender, about 15–20 minutes. Drain well.
Arrange potatoes on the prepared baking sheet. Using the bottom of a glass or a fork, gently press each potato until flattened to about ½ inch thick.
Drizzle generously with olive oil. Scatter minced garlic and fresh herbs over the top. Season with salt and pepper.
Roast for 25–30 minutes, until edges are deeply golden and crispy.
Remove from oven. Top immediately with grated Parmesan and more fresh herbs and chives.
Serve hot — straight from the pan is encouraged.
