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. 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 incorporated.
04 - Place chicken breasts in the prepared baking dish, spacing them evenly. Pound chicken to even thickness if needed for uniform cooking.
05 - Spread cream cheese mixture evenly over each chicken breast. Top with shredded cheddar cheese followed by crumbled bacon.
06 - Bake for 25 minutes until chicken is cooked through (internal temperature reaches 165°F) and cheese is bubbly and lightly golden.
07 - Remove from oven and let rest for 5 minutes. Garnish with sliced green onions, additional cheese, and fresh chives if desired. Serve hot.
