place chicken breasts in a 9X13 pan if you choose you can cut them in thirds. Melt butter in sauce pan add the italian dressing mix then add the other ingredients stir until it is melted. Pour over chicken, cover and bake for an hour.
I did add cheese to the top just before I pulled it out of the oven we are big cheese eaters but it really didn't need it. Plus I think I would like it better with penne noodles. It is very saucy but that is the best part.I also will add fresh mushrooms then next time I make it
