Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Wash and scrub the potatoes thoroughly. There’s no need to peel them.
Place a potato between two chopsticks or wooden spoons. This will prevent you from cutting all the way through.
Using a sharp knife, make thin, even slices across the potato, about ⅛-inch apart. The cuts should go almost to the bottom but not completely through.
Repeat with the remaining potatoes.
In a small bowl, combine the olive oil, minced garlic, dried rosemary, dried thyme, salt, and pepper.
Brush the potatoes generously with the olive oil mixture, making sure to get in between the slices.
Arrange the potatoes on the prepared baking sheet.
Roast for 45-60 minutes, or until the potatoes are tender inside and crispy golden brown on the outside. The cooking time may vary depending on the size of your potatoes.
Garnish with fresh parsley (if desired) and serve hot.
