I just saw Michael Symon make this on The Chew today and I can't wait to try it! His helpful tips were: 1. No need to remove the gills from the Portobello mushroom for this recipe. Michael does suggest removing the gills when creating a sauce out of the mushrooms. 2. Use any type of stock in this recipe: vegetable, chicken, or beef. 3. Try this sauce on steaks or pork chops, too! If you omit the bacon and use the vegetable broth, it's a nice vegetarian dish. On the TV show, he also saved some of the blue cheese and crumbled it over the top of the dish once it was plated. Enjoy!
