Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Place the sweet potatoes on the prepared baking sheet. Drizzle with olive oil and toss until well coated.
Add the maple syrup and sprinkle cinnamon, salt, and pepper over the sweet potatoes. Toss again to cover evenly.
Arrange the sweet potatoes in a single layer, making sure they don't touch.
Roast for 25 to 30 minutes, until tender and browned, stirring halfway through for even cooking.
Remove from oven and let cool for a few minutes before serving. Enjoy the sweet and savory flavor!
