Preheat oven to 220°C and line a large rimmed baking sheet with parchment paper or foil.
02 -
Peel the sweet potatoes and cut them into 2 cm cubes, ensuring pieces are uniform for even cooking.
03 -
In a large bowl, toss the sweet potato cubes with olive oil, kosher salt, black pepper, and ground cinnamon until evenly coated.
04 -
Spread the sweet potatoes in a single layer on the prepared baking sheet, using two pans if necessary to avoid crowding. Roast for 15 minutes until edges begin to caramelize.
05 -
While roasting, combine honey and melted unsalted butter in a small bowl.
06 -
Remove the pan from the oven, drizzle the honey butter mixture over the sweet potatoes, and toss gently to coat. If using, sprinkle chopped nuts evenly atop the potatoes.
07 -
Return to oven and roast for an additional 12 to 15 minutes, stirring once halfway through, until the sweet potatoes are tender inside and have a sticky, golden exterior.
08 -
If desired, sprinkle with fresh herbs, toss lightly to distribute, adjust seasoning to taste, and serve immediately to preserve texture.
