01 - Preheat the oven to 400°F. Lightly grease a baking dish with olive oil or non-stick spray.
02 - In a small mixing bowl, combine the softened goat cheese, chopped chives, parsley, minced garlic, lemon zest, 1/4 tsp black pepper, and a pinch of salt. Stir until the mixture is smooth and creamy.
03 - Using a small sharp knife, carefully cut a deep pocket into the thickest part of each chicken breast, being careful not to cut all the way through to the other side.
04 - Generously fill each pocket with the goat cheese mixture. Secure the openings with toothpicks if needed to keep the filling contained during baking.
05 - Rub each stuffed chicken breast with olive oil, then season evenly on all sides with 1/2 tsp salt, 1/2 tsp black pepper, and paprika if desired.
06 - Arrange the stuffed chicken breasts in the prepared baking dish and bake uncovered for 25 to 30 minutes, until the internal temperature reaches 165°F and juices run clear.
07 - Remove the chicken from the oven and discard any toothpicks. Let the breasts rest for 5 minutes before slicing and serving to allow the juices to redistribute.
