Ingredients

  • salt
  • ½ teaspoon baking soda
  • 2½ pounds sweet potatoes (about 3 large), unpeeled, cut into 1½-inch (4-cm) chunks
  • 2 tablespoons Potato Starch (see note)
  • 3 tablespoons olive oil
  • 1 tablespoon chopped fresh rosemary, divided
  • ¼ teaspoon freshly ground black pepper

Instructions

    Cup of Yum
  1. Preheat the oven to 450°F (230°C) and set an oven rack in the middle position.
  2. In a large pot, bring 3 quarts (3 L) of water to a boil. Stir in 1 tablespoon of salt and the baking soda. Add the potatoes and boil for 10 minutes.Drain the potatoes thoroughly.
  3. Directly on a rimmed baking sheet (avoid using foil as the potatoes may stick), toss the par-boiled potatoes with the potato starch, oil, ½ teaspoon of salt, half of the rosemary, and the pepper. Roast in the preheated oven for 35 minutes, stirring once midway through roasting. After roasting, turn off the oven but leave the potatoes inside for an additional 10 to 15 minutes.
  4. Remove from the oven and sprinkle with the remaining rosemary. Taste and adjust the seasoning with salt, if necessary. Transfer the sweet potatoes to a platter and serve.

Notes

  • Notes: In most supermarkets, you can find potato starch in the baking aisle alongside other starches and thickeners like cornstarch. It may also be in the gluten-free or international foods aisle, especially within the Kosher or Asian sections. Some stores that have distinct sections for natural or organic foods might also stock potato starch there. If you're having difficulty finding it, ask a store employee. The sodium content provided in the nutritional section for the potatoes is based on the assumption that about ½ teaspoon of salt is absorbed during boiling in salted water. This is just an estimate, and the actual sodium level can vary.
