01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper for easy cleanup and to prevent sticking.
02 - Place sweet potato cubes in a large bowl. Add olive oil, ground cinnamon, sea salt, and black pepper. Toss thoroughly until all pieces are evenly coated. Incorporate maple syrup and nutmeg if desired.
03 - Spread the seasoned sweet potatoes across the prepared baking sheet in a single, even layer. Avoid overcrowding to ensure proper caramelization and crisping.
04 - Roast for 25–30 minutes, flipping the potatoes halfway through cooking. The finished sweet potatoes should display golden-brown edges and offer tender, caramelized sweetness when pierced with a fork.
05 - Transfer to a serving dish while still warm. Dust with additional cinnamon if preferred and serve immediately alongside your main course.
