01 - Preheat the oven to 400°F. Lightly grease a 9x13-inch baking dish with cooking spray or a small amount of oil.
02 - In a medium bowl, combine the softened cream cheese, ranch seasoning mix, garlic powder, and black pepper. Mix thoroughly until completely smooth and well incorporated.
03 - Place the chicken breasts in the prepared baking dish in a single layer, ensuring even spacing for consistent cooking.
04 - Spread the cream cheese mixture evenly over each chicken breast. Sprinkle shredded cheddar cheese over the top, followed by the crumbled bacon.
05 - Bake uncovered for 25 to 30 minutes, or until the chicken is completely cooked through and reaches an internal temperature of 165°F when tested with a meat thermometer.
06 - Remove the dish from the oven and let the chicken rest for 5 minutes to allow juices to redistribute. Garnish with sliced green onions and fresh parsley just before serving.
