01 - Preheat the oven to 400°F. Lightly grease a baking dish.
02 - In a small bowl, combine the goat cheese, chives, parsley, garlic, lemon zest, 1/4 tsp black pepper, and a pinch of salt. Mix until smooth and creamy.
03 - Using a small sharp knife, cut a deep pocket into each chicken breast, being careful not to slice all the way through.
04 - Carefully fill each breast with the goat cheese mixture. Secure the opening with toothpicks if needed.
05 - Rub the stuffed chicken breasts with olive oil, then season evenly with 1/2 tsp salt, 1/2 tsp black pepper, and paprika if using.
06 - Place the stuffed breasts in the prepared baking dish and bake uncovered for 25 to 30 minutes, until the chicken is cooked through and the juices run clear.
07 - Remove toothpicks before serving and let the chicken rest for 5 minutes.
