Preheat the oven to 425°F. Lightly grease a large sheet pan with cooking spray.
In a small bowl, stir together the smoked paprika, cumin, garlic powder, onion powder, coriander, cinnamon, and red pepper flakes.
Add the sweet potatoes to a medium bowl and toss with the olive oil, ⅓ of the spice blend, salt, and black pepper. Add to the sheet pan and spread into an even layer.
Roast the sweet potatoes for 10 minutes.
Meanwhile, add the chicken to a medium bowl. Toss with the olive oil, remaining spice blend, salt, black pepper, and honey until evenly coated.
Stir and flip the sweet potatoes, then move to one side of the sheet pan. Add the chicken to the other side and spread into an even layer. Roast for another 10–12 minutes, or until the sweet potatoes are tender and the chicken is cooked through and reaches an internal temperature of 165°F.
