Heat oven to 425 degrees Fahrenheit. Line a rimmed baking sheet with parchment paper.
In a large bowl, mix the sweet potato half-moons with olive oil, maple syrup if using, salt, pepper, and thyme leaves until every piece is lightly coated.
Spread in a single layer on the baking sheet so the pieces are not touching.
Roast for 12 to 14 minutes, flip with a spatula, then roast 10 to 12 minutes more, until the edges are caramelized and the centers are tender.
Transfer to a plate and garnish with a few fresh thyme sprigs.
