01 - Preheat oven to 400°F. Lightly grease a baking dish with olive oil or cooking spray.
02 - In a small mixing bowl, combine 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 cut all the way through.
04 - Generously fill each pocket with the goat cheese mixture. Secure the openings with toothpicks if needed to keep filling inside.
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 stuffed breasts in the prepared baking dish and bake uncovered for 25 to 30 minutes, until chicken is cooked through and juices run clear.
07 - Remove from oven, discard toothpicks, and let rest for 5 minutes before serving.
