I did not realize I had not rated this recipe, I have made it twice. It is absolutely delicious. The only changes I made were: use one whole onion, used a little more butter, used a 10 oz. package mushrooms, only used a dash of sea salt and ground pepper. I did not use tarragon or rosemary.
I added some Italian Panko breadcrumbs to the top of the fish. I added Swiss cheese at the end of cooking time to melt.
