Crispy Baked Sweet Potatoes

Preheat oven to 400F.

Using a mandolin slicer, thinly slice the peeled potatoes length ways. Pat dry the potatoes with paper towels.

Place the sliced sweet potatoes in a large bowl. Toss with butter, salt, black pepper and chopped rosemary/oregano, until fully coated.

Carefully place the sweet potatoes upright, from left to right, in a small baking tray. Do not pack in the sweet potatoes too tightly, as this impacts the crispiness.

Bake for an hour, or until the sweet potatoes are cooked and turn crispy. Serve immediately.
