Layer chicken and seasonings: Place chicken breasts in the bottom of the crockpot. Sprinkle ranch dressing mix evenly over the chicken.
Add cream cheese: Place the block of cream cheese on top of the chicken.
Cook: Cover and cook on low for 6–7 hours or high for 3–4 hours, until chicken is cooked through and tender.
Shred and mix: Shred chicken directly in the crockpot using two forks. Stir well to combine with melted cream cheese and ranch seasoning.
Add cheddar and bacon: Stir in shredded cheddar cheese and crumbled bacon. Cover for 5–10 minutes until cheese is fully melted.
Finish with green onions: Sprinkle sliced green onions on top for freshness.
Serve: Pile onto sandwich buns, wraps, or serve over rice, pasta, or roasted veggies.
