Place the chicken thighs into the base of a slow cooker. Evenly sprinkle the ranch seasoning over the meat. Position the cream cheese directly atop the chicken.
Secure the lid and set the slow cooker to LOW for 7 hours, keeping the lid closed throughout the cooking duration.
Once the cooking time is complete, use two forks to shred the chicken directly within the slow cooker. Thoroughly mix in the melted cream cheese, then fold in the bacon pieces to combine uniformly. Spread the mixture into a level layer.
Top the chicken blend with shredded cheddar cheese. Replace the lid and allow it to continue warming for an additional 10 minutes until the cheese has fully melted.
Serve the finished dish over cooked rice, and garnish with green onions. This versatile meal also pairs wonderfully with baked potatoes or on sandwich rolls.
