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 6-8 minutes. 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 the cream cheese mixture evenly over each chicken breast, covering completely.
05 - Sprinkle shredded cheddar cheese over the cream cheese layer, followed by the crumbled bacon.
06 - Bake for 25 minutes, or until chicken is cooked through (internal temperature reaches 165°F) and cheese is bubbly and lightly golden.
07 - Remove from oven. Garnish with sliced green onions, extra shredded cheese, and chopped chives if desired. Serve immediately while hot.
