Preheat your oven to 400°F.
Pat dry the chicken breast and lightly season with a pinch of salt, pepper, and dried thyme.
In a small bowl, mix maple syrup with a tiny bit of olive oil to create a glaze.
Brush the chicken breast with half of the maple glaze and set aside.
Peel (if desired) and cube the sweet potato into bite-sized pieces. Toss them with the remaining olive oil, salt, pepper, and thyme.
Place the sweet potato cubes on a baking tray lined with parchment paper and roast in the preheated oven for 20-25 minutes until tender and slightly crisp on the edges.
Meanwhile, heat a skillet over medium-high heat. Sear the glazed chicken breast for 2-3 minutes on each side until a golden crust forms.
Transfer the seared chicken breast to the oven (or cover it with the sweet potatoes during the last 10 minutes) to finish cooking through, reaching an internal temperature of 165°F.
Once done, slice the chicken and serve over or alongside the roasted sweet potatoes for a balanced meal.
