I did make this tonight. We had a friend over for dinner (his wife is out of town) and he raved about it. DH and I both enjoyed it as well. Basically, it makes a beef gravy with onions over the chicken. I thought I had a block of Swiss cheese, but apparently left it at my son's house when we were there. (I originally was going to make it for them, but they lost power before noon and it didn't come back on until after 7, too late to make dinner.) I found some sliced Swiss cheese purchased for sandwiches, and cut that into strips and chopped it. Recipe calls for 1/4 cup of grated Swiss. I used 1/2 cup of what I had and it really was not enough. That is saying a lot since I normally don't like to use a lot of cheese. Next time I will use at least one cup and hope I don't have to use sliced Swiss! I told DH that it was lacking something, (he said "I thought it was really good." ) but I can't put my finger on it. I used 1/2 tsp. of the herbs as indicated, and 1/2 tsp. each of salt and pepper. Maybe it could use more salt.
Also, with more cheese, I would leave it in the oven longer than I did (15+/- minutes)so that the cheese gets crusty. I definitely will make this again, using the little changes I suggest above.
