Line bottom of 13x9 casserole with 1 small jar dried beef. Lay chicken breasts on top of beef.
Mix 8 ounces of sour cream and 1 can cream of mushroom soup and pour over chicken. Lay 4 slices bacon on top. Bake at 300 degrees for 2 hours or until chicken is done. I usually cut the chicken breasts up in smaller pieces and will freeze what is leftover in individual containers.
