Preheat the oven to 400°F (200°C). Line two large baking sheets with parchment paper and set aside.

Peel the sweet potatoes and slice them into paper-thin rounds, using a mandolin slicer or a sharp knife.

In a large mixing bowl, combine olive oil, salt, and black pepper. Add the sweet potato slices to the bowl and toss to coat evenly.

Spread the sweet potato slices out evenly on the prepared baking sheets, ensuring they’re in a single layer with space around each chip.

Bake for about 10-12 minutes on each side, until golden brown and crispy. Remove from the oven and let cool on cooling racks for 5-10 minutes to firm up.

Enjoy your delicious homemade sweet potato chips as a healthy snack!
