Place the chicken breast in the bottom of the crockpot. Sprinkle the ranch seasoning over the chicken, then pour in the chicken broth. Add the cubed cream cheese.
Set on high for 4 hours or low for 6 hours. When the chicken has cooked, remove the chicken and shred, then add the chicken back into the slow cooker.
Add the baby spinach and cheese. Stir and place the lid back on and cook for another 30 minutes until the spinach has wilted and the cheese is melted.
Stir in the bacon and serve bowls of soup with a sprinkle of green onion.
