I was looking for a recipe for the brussels sprouts I got as part of my share from the organic farm and when I saw this had thyme (my favorite herb) and gruyere (one of my very favorite cheeses) I grabbed it. Good choice--it was FABULOUS! I followed *Parsley*'s suggestion and used a Vidalia onion. Rich with lots of flavor.
I am happy to be the first to review this recipe because it is outstanding! I did use the optional garlic and my onion was a Vidalia, so it gave this dish a wonderful sweetness. I used a combination of gruyere and Gouda cheeses. This is a real keeper that will be made again. Thanx for posting!
