01 - Preheat the oven to 350°F.
02 - Season chicken breasts evenly with salt, pepper, and half of the Italian herbs.
03 - In a large ovenproof skillet, melt the butter over medium heat. Add chicken and sear each side for 2–3 minutes until lightly golden. Remove and set aside.
04 - In the same skillet, sauté the chopped onion for 2–3 minutes until soft. Add garlic and cook another 30 seconds until fragrant.
05 - Reduce heat to low. Add cream cheese and milk, stirring until smooth and well combined. Stir in Parmesan cheese and the remaining Italian herbs.
06 - Return the chicken breasts to the skillet, turning to coat evenly with the cream sauce. Transfer the skillet to the oven and bake for 20–25 minutes, or until chicken reaches an internal temperature of 165°F.
07 - Garnish with chopped fresh parsley before serving.
