01 - Preheat the oven to 400°F and line two baking sheets with parchment paper.
02 - Using a sharp knife or mandoline, slice the sweet potatoes into very thin rounds, about 1/8 inch thick.
03 - Toss the sweet potato slices in a large bowl with olive oil, sea salt, black pepper, and smoked paprika if using, until evenly coated.
04 - Place the sweet potato slices in a single layer on the prepared baking sheets, ensuring they do not overlap.
05 - Bake for 12 to 15 minutes, then flip each chip and rotate the trays. Continue baking for an additional 8 to 12 minutes until golden brown and crisp.
06 - Remove from the oven and allow the chips to cool on the trays for a few minutes to crisp up further before serving.
