Heat the oven to 425°F. Pour enough of the oil into a large cast-iron skillet, tilting it, to cover the bottom of the pan. Strip the leaves from the rosemary sprig and scatter them over the bottom of the pan. Sprinkle the salt over the rosemary. Scrub the potatoes, cut them in half, and set them cut side down on the rosemary and salt. Roast on the lowest oven rack until the potatoes are tender and the bottoms are crisp and well browned, 30 to 40 minutes. nutrition information (per serving): Size : based on four servings, Calories (kcal): 130, Fat (kcal): 7, Fat Calories (g): 60, Saturated Fat (g): 1, Protein (g): 2, Monounsaturated Fat (g): 5, Carbohydrates (mg): 15, Polyunsaturated Fat (mg): 1, Sodium (g): 370, Cholesterol (g): 0, Fiber (g): 1, Photo: Scott Phillips Rate this Recipe and View Reviews
