Add chicken to the slow cooker and sprinkle with ranch seasoning, garlic powder, and pepper.
Dot the cream cheese over the chicken. Add broth if you like a looser sauce.
Cook on low for 6 to 7 hours or on high for 3 to 4 hours until the chicken is tender.
Shred the chicken in the cooker until the sauce turns creamy and smooth.
Stir in half of the cheddar and half of the bacon until melted.
Top with the remaining cheddar, cover for a few minutes to melt, then finish with bacon and green onions.
Serve on toasted buns, over rice, tucked in tortillas, or piled on crisp lettuce.
