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 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 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 inside during baking.
05 - Rub the outside of each stuffed breast with olive oil, then season evenly with 1/2 tsp salt, 1/2 tsp black pepper, and paprika if using.
06 - Arrange the stuffed breasts in the prepared baking dish and bake uncovered for 25–30 minutes, until the internal temperature reaches 165°F and juices run clear.
07 - Remove from the oven and discard any toothpicks. Let the chicken rest for 5 minutes before serving to allow the juices to redistribute.
