Lay the chicken thighs out on the bottom of a crock pot. Cover evenly with ranch seasoning and pesto. Then add chicken broth or water to the bottom of the crock pot.
Cook on high for 3-4 hours or on low for 5-6.
When there is about 1-2 hours (for low) or 30 min-1 hour (for high) before serving, add in your bag of frozen broccoli.
When ready to serve, if preferred, you can shred the chicken with two forks.
You can sub for chicken breast; however, it will likely be a little bit drier than chicken thighs!
