01 - Preheat oven to 400°F. Lightly grease a baking dish with cooking spray or butter.
02 - Cook bacon in a skillet over medium heat until crispy, about 5-7 minutes per side. Drain on paper towels and crumble once cooled.
03 - In a medium bowl, combine softened cream cheese, ranch seasoning mix, minced garlic, and black pepper. Mix until smooth and well blended.
04 - Place chicken breasts in the prepared baking dish. Spread cream cheese mixture evenly over each chicken breast, covering the top surface.
05 - Sprinkle shredded cheddar cheese over the cream cheese layer, followed by the crumbled bacon pieces.
06 - Bake for 25 minutes or until chicken reaches an internal temperature of 165°F and cheese is bubbly and lightly golden.
07 - Remove from oven. Top with sliced green onions, extra shredded cheese, and fresh chives if desired. Serve immediately while hot.
