Preheat your oven to 400°F (200°C).
In a large mixing bowl, combine the cubed sweet potatoes, maple syrup, olive oil, and cinnamon. Toss until the sweet potatoes are evenly coated.
Transfer the sweet potato mixture to a baking dish, spreading them out in an even layer. Add nuts if desired.
Bake in the preheated oven for 25-30 minutes, or until the sweet potatoes are tender and lightly caramelized, stirring halfway through the cooking time.
Remove from the oven and let cool slightly before serving.
Variations & Tips
For a bit of crunch, consider adding chopped pecans or walnuts to the sweet potato mixture before baking. If you prefer a spicier kick, a pinch of cayenne pepper can be added to the cinnamon for a sweet and spicy contrast. You can also experiment with different herbs, such as rosemary or thyme, to add an aromatic depth to the dish. For a vegan version, ensure that the maple syrup is pure and not processed with any animal products.
