I made it just as the recipe states. The finished dish isn't soupy, it's a clump of cooked chicken with the mayo/seasoned spread on top, surrounded by the fat and water that cooked out of the chicken. It's tasty to be sure but could benefit from some additional seasonings. I think it might be better if the chicken were partially cooked before putting it in the baking dish and covering with the mayo mixture. Then it would not come out of the oven so wet.
I'll play with it and make it again.
