My family loves this casserole and it is something different to do with chicken. You could make this with any chicken parts other than chicken breasts, too.4 to 6 chicken breasts, boneless and skinned 4 to 6 slices Swiss cheese 1 (10 1/2 ounce) can Campbell’s cream of chicken soup 1/3 cup onion, chopped 1 (4 ounce) can mushroom pieces, drained 1 cup milk 1/4 teaspoon black pepper 1/2 teaspoon rubbed sage 1/4 teaspoon ground mustard 1 (14 ounce) can Campbell’s chicken gravy 1 (6 ounce) box chicken flavored stuffing mix (I used Kroger brand) 1/2 stick butter or margarine or 4 tablespoons, melted Spray a 9 x 13 baking dish or a deep dish casserole with cooking spray. Place chicken breasts in pan and place a slice of swiss cheese on each breast. Mix remaining ingredients in a bowl with a whisk, pour in uncooked stuffing mix and stir. Pour over the chicken. Cook covered in a preheated 350 degree oven for 60 minutes. Remove cover for last 15 to 20 minutes. (If your chicken is frozen when you are putting the casserole together, you should cook about 90 minutes to make sure chicken breasts are done). Enjoy! Note: I have not made this dish in the crockpot but feel like it would work that way, too. Click to follow The Southern Lady Cooks on Facebook.
