This Crispy Baked Sweet Potatoes recipe is the BEST roasted sweet potatoes ever. They are thinly sliced and baked to crispy and buttery goodness. So delicious!
Preheat oven to 400F.
Using a mandolin slicer, thinly slice the peeled potatoes. Pat dry the potatoes with paper towels.
Place the sliced sweet potatoes in a large bowl. Using your hands, 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.
You may use 5 oz. of duck fat instead of butter.
