Preheat the oven to 450°F (230°C).
Line a baking sheet with parchment paper or aluminum foil and coat it with cooking spray.
Place the sweet potato strips on the prepared baking sheet, ensuring they are spread out evenly.
Lightly coat the sweet potato strips with non-stick cooking spray.
Drizzle the olive oil over the sweet potato strips, then sprinkle with salt and pepper.
Toss the sweet potato strips gently to evenly distribute the oil, salt, and pepper.
Spread the sweet potato strips out in a single layer on the baking sheet, ensuring they are not overcrowded.
Bake the sweet potato fries in the preheated oven for 20 to 25 minutes, or until they are golden brown and crispy, stirring halfway through the cooking time to ensure even browning.
Once baked, remove the sweet potato fries from the oven and serve them hot as a delicious side dish or appetizer.
