Preheat the oven to 425°F. Line a baking sheet with parchment paper for easy cleanup.
Peel (if desired) and cube the sweet potato into 1-inch pieces. Toss them with olive oil, salt, and pepper, then spread evenly on the prepared baking sheet.
Place the sweet potatoes in the oven and roast for about 25-30 minutes, until tender and lightly caramelized.
Meanwhile, pat the chicken breast dry with paper towels. In a shallow dish, combine the panko bread crumbs, garlic powder, and a pinch of salt and pepper.
Brush the chicken breast lightly with maple syrup, then dredge in the panko mixture, pressing the crumbs onto the surface to adhere well.
Heat a non-stick skillet over medium heat. Add a light drizzle of olive oil and sear the chicken for 2-3 minutes per side until a crispy crust forms.
After searing, transfer the chicken to a baking tray and drizzle any remaining maple syrup on top. Bake in the preheated oven for an additional 10-12 minutes or until the internal temperature reaches 165°F.
Once the chicken and sweet potatoes are done, plate them together and serve warm.
