Preheat oven to 425 degrees with the rack in the upper third. Line a baking sheet with parchment paper.
In a medium size mixing bowl, combine all ingredients and toss to coat the sweet potatoes evenly. Spread in an even layer on the baking sheet. Roast in the oven for 30 minutes, until the sweet potatoes are golden brown. You don’t need to toss the sweet potatoes while they’re roasting.
