In a crockpot, add chicken broth and half the package of taco seasoning.
Whisk together to blend.
Add chicken thighs to crock pot and the rest of taco seasoning on top of chicken thighs.
Push down a little on the thighs to submerge them a bit.
Cook on low for 5 hours or on high for 3-4 hours.
Serve with sour cream and garnish with green onions and red pepper flakes (optional).
Please add up any additional optional ingredients you add.
