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