Love portobello mushrooms, love this recipe. I served these as a side dish with BBQ leg of lamb. Followed the recipe added a bit more garlic and instead of slicing the mushrooms I left them whole, put the asiago on them for the last minute in the oven and then drizzled them with the vinaigrette. No complaints from any one- another winner Thanks Dancer.
GREAT!! loved them! i doubled the shallots and garlic but next time will use less dijon, it was a little overpowering for me. will make again and again!!
These were delicious. I made the recipe using about 8 portabello mushrooms, but keeping the amounts for the vinaigrette the same. There was lots of delicious vinaigrette to go around. I didn't have any asiago cheese so I used Parmesan Reggiano, which is known as an acceptable substitute. Everyone was impressed and delighted with the dish. Thanks for a great recipe!
