Preheat your oven to 375°F (190°C) and line two baking sheets with parchment paper.
Wash and peel the sweet potatoes. Using a sharp knife or a mandoline slicer, carefully slice the sweet potatoes into thin, even rounds. Try to make them as uniform in thickness as possible for consistent cooking.
In a large bowl, toss the sweet potato slices with olive oil, salt, and pepper. If desired, add your choice of seasonings or spices for extra flavor. You can get creative here and use your favorite herbs and spices.
Place the seasoned sweet potato slices in a single layer on the prepared baking sheets. Make sure they are not overlapping to allow for even baking.
Bake the sweet potato chips in the preheated oven for about 15-20 minutes, or until they start to turn golden brown and become crispy. Keep an eye on them as cooking times may vary based on thickness.
Once the chips are done, remove them from the oven and let them cool on a wire rack. As they cool, they will become even crispier. Enjoy!
