A hasselback potato is a type of baked potato. The potatoes are sliced thinly, about half way through. You want the potato to remain one piece, and then stuff the slices as you see fit. We love this recipe for hasselback sweet potatoes.
Hasselback Sweet Potatoes
Ingredients:
4 medium sweet potatoes
1 tablespoon unsalted butter, melted
1 teaspoon olive oil
1 teaspoon finely chopped fresh thyme leaves
1 garlic clove, finely minced
Salt and freshly ground black pepper
6 tablespoons Greek yoghurt or sour cream
1 green onion, white and green parts chopped
Instructions:
Preheat the oven to 400 degrees. Line a baking sheet with aluminum foil.
Make a series of 1/8-inch slices along each potato, slicing 2/3 of the way through. Stir together the butter, oil, thyme, garlic, 1/4 teaspoon salt and 1/4 teaspoon pepper in a small bowl.
Rub the potatoes all over with the mixture, getting in between the slices. Place on the baking sheet and roast until the center of the potatoes are tender and the outside is crisp, 50 minutes to 1 hour.
Halfway through the roasting time, remove the potatoes from the oven and run a fork gently across the tops of the potatoes, using light pressure, to fan the slices and separate them from one another. Meanwhile, stir the yogurt and green onions with a pinch salt and a pinch pepper. Serve the sauce with the potatoes.
