3. Place the chicken breast in a baking dish and brush the honey mustard mixture generously over the top.
4. Bake in the preheated oven for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
5. Remove from the oven and let it rest for a few minutes. Garnish with fresh parsley if desired before serving.
