Sprinkle on a packet of au jus gravy mix and then the ranch seasoning mix. Lay the stick of butter on top of all of the dry mix and surround with pepperoncinis.
Pour a cornstarch slurry back into the crock pot while you are prepping your chicken. Stir into the juices from cooking, and then add your chicken back into the gravy and let thicken.
This dish produces a delicious chicken and gravy you can add on top of mashed potatoes, rice, or egg noodles and makes a mouthwatering meal even grandma would be proud to serve.
