Why It Works

  • Par-cooking the potatoes in 160°F water enhances the development of simple sugars, leading to sweeter and more flavorful roast potatoes.
  • Roasting the potatoes on aluminum baking sheets conducts more heat to them, browning and crisping them better and faster.

Savory and salty miso adds a backbone of deep flavor to these incredibly sweet roasted sweet potatoes.

  • 3pounds(1.4kg)sweet potatoes, peeled and cut into 1/2-inch chunks

  • 4tablespoons(60ml) vegetable orcanola oil, divided

  • Kosher saltand freshly ground black pepper

  • 2tablespoons(30ml) miso (we usedwhite misoduring testing, but you can use any type)

  • 1tablespoon(15ml)mirin

  • 1/2tablespoon(8g)sugar

  • 2tablespoons(30ml)water

  • 2scallions, white and light-green parts only, thinly sliced

  • Shichimi togarashi, for garnish (optional; see note)

Directions

  1. Place sweet potatoes in a large saucepan and cover with cold water. Heat water to 160°F (70°C) as registered on an instant-read thermometer. Cover and set aside for 1 hour.

  2. Adjust oven racks to upper-middle and lower-middle positions and preheat oven to 400°F (200°C). Drain sweet potatoes and transfer to a large bowl. Toss with 3 tablespoons (45ml) oil and season to taste with salt and pepper. Spread sweet potatoes on 2 rimmed baking sheets and roast until bottom sides are browned, about 30 minutes. Carefully flip potatoes with a thin spatula and roast until second side is browned and potatoes are tender, about 20 minutes longer. Keep potatoes warm.

  3. 当准备好服务,在一个大的碗里,搅拌together miso, mirin, sugar, water, and remaining 1 tablespoon (15ml) oil until smooth. Add potatoes and gently toss to coat. Fold in scallions and transfer to a serving bowl. Sprinkle with shichimi togarashi, if using, and serve.

Notes

Shichimi togarashi is a Japanese seven-ingredient chile powder.
