Lay chicken in bottom of large casserole dish so that it is flat and not overlapping. Sprinkle ranch seasoning over top of chicken as evenly as possible. Spread banana peppers over the ranch seasoning. The peppers shouldn’t have much liquid remaining. Top banana peppers with pats of butter. Top evenly with shredded cheese. Bake at 375 degrees on middle rack in oven for 30-40 minutes or until chicken is cooked through. Serve hot over rice.
