Hasselback Sweet Potatoes

0 Preheat the oven to 350°F (180°C). Spray a baking dish with nonstick baking spray or rub it with a little olive oil. Set aside.
1 Place the sweet potatoes on a wooden cutting board and between two wooden spoons or metal skewers. With a sharp knife, cut even slices into the sweet potato, stopping about ¼” from the bottom. The spoons or skewers should prevent you from cutting the entire way through. Work slowly, and repeat with all sweet potatoes.
2 Place the hasselback sweet potatoes in the prepared baking dish.
3 In a small bowl, mix olive oil, thyme, rosemary, garlic, salt and pepper together.
4 Rub the sweet potatoes with the oil mixture.
5 Place the seasoned sweet potatoes in the baking dish. Bake for 45 minutes on the center rack of the oven until tender. Check with a skewer to confirm the doneness before removing.
6 In a small bowl, mix the butter and parmesan together.
7 When the sweet potatoes are removed from the oven, drizzle the butter-parmesan directly over them.
8 Serve warm, and enjoy!
