Preheat the oven to 400°F. Line a rimmed baking sheet with aluminum foil, and lightly spray with nonstick spray (or lightly oil the foil).
Cut the fingerling potatoes in half lengthwise, and place them on the prepared baking sheet. Drizzle with the oil, sprinkle over the garlic, rosemary, thyme, salt and pepper, toss to thoroughly combine, and spread out on the baking sheet so that the potatoes are in a single layer.
Roast for about 25 minutes, until the potatoes are tender and lightly browned. Serve hot or warm.
