Gently cooking chicken in a flavorful cooking broth helps it become tender and juicy. We go the extra step to make sure the chicken is as juicy and flavorful as possible. Once the chicken is cooked, we transfer the cooking liquid from the slow cooker to a small saucepan and simmer the liquid down by one-third. Spoon some of the concentrated broth over the chicken and save the rest for a light soup later.
