Preheat the oven to 300°F (150°C) and line two large rimmed baking sheets with parchment paper.
Using a mandoline slicer, cut the sweet potatoes into uniform thin rounds to ensure even cooking.
In a large mixing bowl, combine the sweet potato slices with olive oil, sea salt, smoked paprika, and black pepper.
Toss thoroughly by hand to ensure every slice is lightly and evenly coated with oil and seasoning.
Arrange the slices on the prepared baking sheets in a single layer, ensuring that no slices overlap.
Bake for 12 minutes, then remove the sheets from the oven and flip each chip individually using tongs.
Return the sheets to the oven and bake for another 10 to 13 minutes, monitoring closely to prevent burning as the edges brown.
Remove from the oven and let the chips rest on the baking sheets for 5 to 10 minutes; they will continue to crisp as they cool.
