Combine ground chicken, Parmesan cheese, basil, garlic powder, salt, and pepper in a mixing bowl; mix thoroughly.
Section mixture into 4 equal portions and form into flat, round patties.
Heat a nonstick skillet over medium heat, spraying with cooking spray if needed. Place burgers in the hot skillet and cook until browned and no longer pink, about 5 minutes on each side. Serve on warmed buns.
