Begin by placing the boneless, skinless chicken thighs into the base of a slow cooker or Instant Pot. Evenly sprinkle the ranch dressing seasoning mix, garlic powder, onion powder, and salt and pepper over the chicken. Ensure the chicken is well coated with the seasonings.
Carefully dollop the softened cream cheese on top of the seasoned chicken, spreading it out so it covers as much of the chicken as possible.
For Slow Cooker: Cover the slow cooker and set it to low heat for 6-7 hours or on high heat for 3-4 hours. Cook until the chicken is fork-tender and can be easily shredded. For Instant Pot: Seal the lid and cook on high pressure for 15 minutes. Once the cooking cycle has finished, allow for a natural pressure release for additional tenderness.
After the chicken is fully cooked, use two forks to shred the chicken into bite-sized pieces within the cooking pot. Stir the mixture thoroughly to blend the cream cheese with the shredded chicken completely.
Next, incorporate the shredded sharp cheddar cheese and the optional bacon bits (if using) into the chicken mixture, stirring until the cheese has melted and everything is evenly combined.
Finally, gently fold in most of the chopped green onions, reserving a small handful for garnish at the end.
Notes
Serve warm in bowls, garnished with green onions and extra cheese. Pairs well with steamed broccoli or cauliflower.
