2) Put the potatoes into a large bowl. In a small bowl, whisk the herbs, garlic, and oil together until blended, and then pour over the potatoes. Sprinkle generously with salt and pepper and toss to coat.
3) Transfer the potatoes to a heavy large baking dish, spacing them evenly apart. Roast the potatoes until they are tender and golden, turning them occasionally with tongs, about 1 hour.
4) Transfer the roasted potatoes to a decorative platter and drizzle with extra-virgin olive oil and herbes de Provence, if desired.
