Method
- Preheat oven to 425°F (220°C) with racks in the upper and lower thirds. Line two large rimmed baking sheets with parchment paper.
- Slice the unpeeled sweet potatoes into uniform ¼-inch thick rounds using a sharp knife or mandoline.
- In a small bowl, whisk together the olive oil, cornstarch (if using), smoked paprika, garlic powder, onion powder, salt, and pepper.
- Place sweet potato rounds in a large bowl. Pour the oil-spice mixture over them and use your hands to toss until each round is evenly coated.
- Arrange the rounds in a single layer on the prepared baking sheets, ensuring they do not touch.
- Roast for 15 minutes. Remove sheets, flip each round over, and rotate the sheets from top to bottom. Return to oven.
- Roast for another 10-15 minutes, or until tender inside, golden brown, and crispy on the edges.
- Transfer to a platter, garnish with flaky salt and fresh herbs if desired, and serve immediately.
Notes
For best results, do not overcrowd the baking sheets. Slices must be in a single layer. Cornstarch is optional but highly recommended for maximum crispiness. Leftovers can be re-crisped in a 400°F oven or air fryer.
