Ingredients
1 tablespoon chopped fresh thyme or rosemary (optiional)
3 tablespoon olive oil, melted butter, or duck fat
2 lb waxy potatoes, left whole if small, halved or cut into chunks, if large
1 teaspoon coarse salt
Plenty of fresh ground black pepper
Directions
Heat the oven to 375 degrees. Spread the potatoes in a single layer in a medium roasting pan or rimmed baking sheet. Drizzle with the oil, season with the herbs, salt, and pepper, and toss to coat well. Roast, tossing with a spatula a few times to prevent sticking, until the potatoes are very tender throughout and the skins are somewhat shriveled and crisp, 50-60 minutes, depending on their size and variety. Serve hot.
