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.
Bake in the preheated oven for 25-30 minutes, or until tender and slightly caramelized.
Place the sweet potatoes on the prepared baking sheet. Drizzle with olive oil and toss until well coated.
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Remove from oven and let cool for a few minutes before serving. Enjoy the sweet and savory flavor!
Stir the sweet potatoes halfway through cooking time for even baking.
