01 - Preheat oven to 400°F. Lightly grease a 9x13 inch baking dish with cooking spray or butter.
02 - Cook bacon in a skillet over medium heat for 5-7 minutes until crispy. Transfer to paper towels to drain, then crumble into pieces once cooled.
03 - In a medium bowl, combine softened cream cheese, ranch seasoning mix, minced garlic, and black pepper. Mix thoroughly until smooth and well incorporated.
04 - Arrange chicken breasts in a single layer in the prepared baking dish. Spread the cream cheese mixture evenly over the top of each breast, covering completely.
05 - Sprinkle shredded cheddar cheese over the cream cheese layer, then top evenly with the crumbled bacon pieces.
06 - Bake for 25 minutes until chicken reaches an internal temperature of 165°F and cheese is melted and bubbly with golden edges.
07 - Remove from oven and let rest for 5 minutes. Garnish with sliced green onions, additional shredded cheese, and fresh chives if desired. Serve immediately.
