Chef's Notes

The nutrition data for this recipe includes information for the full amount of the marinade ingredients. Depending on marinating time, ingredients, cooking method, etc., the actual amount of the marinade consumed will vary.


  1. Absolutely delicious! Do not turn - grill one side only! I wasn't sure if the mushrooms needed to be turned over as it seemed all the goodies would just fall out so I grilled a couple on both sides and they weren't nearly as good.
  2. I think this could be very good, but there is WAY too much balsamic vinegar flavor when following the recipe. The mushroom was very tender and all the other ingredients made gave it great flavor, but it was almost unedible with all the vinegar. I will probably make them again with 1/2 the amt of - Read more ...
  3. quick easy and ADDICTING! bet you can t make them just once... I made burgers with them... Swiss cheese horseradish sauce tomatoes red onion lettuce.
  4. These are great as a meatless sandwich. We've melted cheese over them and serve them on a hamberger bun with lettuce and tomato. These are wonderful.
  5. Good easy recipe for tasty grilled mushrooms. I grilled them and made sandwiches with mozzarella cheese, mayo and roasted red peppers on a toasted whole wheat roll. Used 3 tbsp balsamic vinegar and that was definately enough. Yum!
  6. I tried this recipe on my picky husband and he actually liked it. My kids didn't care for it, though. I tried this marinade on steak and grilled it. I've never had such a wonderful steak, at home or in a restaurant!
  7. This was a big hit at our house. My husband said it tasted like grilled steak and asked for seconds. That's the highest rating you can get from him.
  8. I have tried this recipe and thoroughly enjoyed it.

All it means is that you have to be somewhat organized - but that's not so bad. Definitely - Read more ...
  9. The perfect thing to serve when you are entertaing both vegetarian and non-vegetarian guests. The grilled portobellos are wonderful served as a "steak" or sliced and served over pasta. They're even better served as a sandwich on french bread with sundried tomato pesto. Wow!
