Magical Portabella Mushrooms on a Grill

For years I have been preparing these BBQ mushrooms for vegetarians and meatlovers alike. Portabella mushrooms are so meaty that they can easily be grilled, topped with some melted camembert, lettuce and roasted tomatoes et voila dinner is served. For the meatlovers in the family, I often serve them as a side to a grilled piece of fish.

The other day, as my son Patrick was heading off to University, he asked me how to prepare his favorite magical mushrooms. I said that it was so easy yet did not have a recipe. At that point,  I made a mental note to jot down the recipe the next time I made them.


So, today is that lucky day. A very easy recipe with a marinade that can be used for mushrooms or a piece of sushi style tuna, seared on the grill, topped with these delectable shrooms. In other words a 2 in 1 deal.

I always like to prepare the marinade before cutting up the mushrooms(or leave them whole depending on what they are being used for) and adding them to their waiting flavour bath.


Cut and ready

A trick that works well when marinading these mushrooms is to use a ziplock bag(I wash and reuse them)so that all parts can sit in the sauce.

I also use a veggie basket or a pizza sheet, with holes, to BBQ these treats. Less fall through the grill and unlike the oven, they do not boil in the marinade .
