Preheat your oven to 400°F (200°C).
In a large bowl, combine the maple syrup, olive oil, garlic powder, salt, pepper, and thyme.
Add the chicken thighs to the bowl, coating them thoroughly with the glaze.
Spread the cubed sweet potatoes on a baking sheet and drizzle with olive oil, salt, and pepper.
Nestle the glazed chicken thighs among the sweet potatoes on the baking sheet.
Bake in the preheated oven for 35-40 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
Let the chicken rest for 5 minutes before serving.
Serve the chicken with the roasted sweet potatoes, drizzled with any remaining glaze.
