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 combined.
03 - Place the chicken breasts in the prepared baking dish in a single layer. Spread the cream cheese mixture evenly over the top of each chicken breast, covering completely.
04 - Sprinkle the shredded cheddar cheese evenly over the cream cheese-coated chicken. Top with the crumbled bacon, distributing it across all pieces.
05 - Bake uncovered for 25–30 minutes, or until the chicken is completely cooked through and reaches an internal temperature of 165°F. The cheese should be melted and bubbly.
06 - Remove from oven and let the chicken rest for 5 minutes before serving. Garnish with sliced green onions and fresh parsley if desired.
