Originating in Sweden, Hasselback potatoes feature decorative slices on top and are really quite easy to prepare. As they roast, their edges become wonderfully crispy while the interiors emerge moist and creamy. Here, we use the same technique with sweet potatoes and also add a savory, nutty topping of fresh thyme, Parmesan cheese and pecans.

Ingredients:

  • 3 Tbs. extra-virgin olive oil, plus more for drizzling
  • 1/4 cup (2 oz./60 g) firmly packed light brown sugar
  • 1 garlic clove, grated
  • 3/4 cup (3 oz./90 g) pecans, chopped
  • 2 tsp. chopped fresh thyme
  • Kosher salt and freshly ground pepper
  • 1 cup (4 oz./120 g) grated Parmesan cheese
  • 4 small sweet potatoes

Directions:

  • Preheat an oven to 400°F (200°C). Line a square baking pan with aluminum foil.
  • In a bowl, stir together the olive oil and brown sugar until combined. Stir in the garlic, pecans, thyme, 1/2 tsp. salt and 1/2 tsp. pepper. Fold in 1/2 cup (2 oz./60 g) of the cheese. Set the topping mixture aside.
  • Using a sharp knife, cut each sweet potato crosswise into 1/8-inch (3-mm) slices, cutting only three-fourths of the way through the potatoes so they stay intact. Place the potatoes, sliced side up, in the prepared baking pan. Drizzle with olive oil and season generously with salt and pepper.
  • Roast until the potatoes are browned on the outside and tender in the center, 50 to 60 minutes, sprinkling the topping over the potatoes during the last 10 minutes of roasting. Remove from the oven and sprinkle evenly with the remaining 1/2 cup (2 oz./60 g) cheese. Let cool slightly before serving. Serves 4.
