I give this a 4 star as is, however, you can make it a 5 star and that is just what I did for Christmas with rave reviews. I used fresh whole green beans, fresh portabello mushrooms, and panko breadcrumbs for the topping. Fabulous! This is definitely elegant! No more kiddie green bean casserole for us!

This was very good. I didn't have any white wine, so just used more chicken stock instead. I think this recipe would be great with some slivered almonds or chopped water chestnuts. Thanks for posting.
