Skillet Hasselback Sweet Potatoes

Directions

• Preheat oven to 425°. Cut thin slices lengthwise from bottom of sweet potatoes to allow them to lie flat; discard slices. Place potatoes flat side down; cut crosswise into 1/8-in. slices, leaving them intact at the bottom. Arrange sweet potatoes in a 12-in. cast-iron or other ovenproof skillet.
• Stir together next 5 ingredients. Spoon half the butter mixture evenly over sweet potatoes. Bake 35 minutes.
• Meanwhile, add herbs to remaining butter mixture. Toss bread crumbs with Parmesan. Remove skillet from oven. Spoon remaining butter mixture over potatoes; top with bread crumb mixture. Return to oven until potatoes are tender and topping is golden brown, 10-12 minutes. If desired, top with toasted nuts.
