01 - Preheat oven to 400°F. Lightly grease a 9x13 inch baking dish with cooking spray or butter.
02 - Place bacon slices in a large skillet over medium heat. Cook for 5-7 minutes, turning occasionally, until bacon reaches desired crispiness. Transfer to paper towels to drain and cool. Crumble into small pieces once cooled.
03 - In a medium mixing bowl, combine softened cream cheese, ranch seasoning mix, minced garlic, and black pepper. Mix thoroughly with a spoon or spatula until completely smooth and well incorporated.
04 - Place chicken breasts in a single layer in the prepared baking dish. Pat chicken dry with paper towels if needed for better topping adherence.
05 - Spread the cream cheese mixture evenly over the top of each chicken breast, using the back of a spoon to create a smooth, thick layer.
06 - Sprinkle shredded cheddar cheese generously over the cream cheese layer, followed by an even distribution of crumbled bacon pieces.
07 - Transfer baking dish to preheated oven. Bake for 25 minutes, or until chicken reaches internal temperature of 165°F when tested with a meat thermometer, and cheese is bubbly and beginning to brown slightly.
08 - Remove from oven and let rest for 5 minutes. Garnish with sliced green onions and additional shredded cheese or chopped fresh chives if desired. Serve hot alongside your choice of vegetables or cauliflower rice.
