I had a friend in my high school culinary arts class that was a vegetarian. For our final project we were partnered together to create a luncheon to serve to the teachers in the school. After debating what we should serve, we both agreed to go vegetarian. And that is when I tasted my first portobello mushroom burger.
Everyone loved it, and thus started my obsession with portobello burgers. And when I say obsession, I mean, I order it every time it’s on a menu and make it at home as often as possible.
One of the great things about portobello mushrooms is their umami (meaty) taste, which makes mushroom burgers something that even meat-eaters can get behind.
Unlike most vegetarian burger recipes this one does not require any chopping of vegetables or forming of patties which makes this recipe fast! Add the marinade, grill, eat. Yum yum yum.
Note that the idea behind this recipe (the portobello mushroom, the brie cheese and the pesto mayo) are inspired by a mushroom burger that was served at the Falcon Lake Deli in Manitoba, Canada, the restaurant that was owned by our editor Christine’s parents for years and years.
