Add chicken broth and butter to slow cooker
Lay chicken in broth. Drizzle oil on chicken. Season the chicken generously with your seasonings.
Cook on low until internal temp reaches 165. Mine was done in 90 minutes but use a thermometer to be sure. The original recipe said it took 3 hours. Crockpots will vary.
Remove to a cutting board and cover 10 mins. before slicing.
