Make this portobello mushroom burger
Mushrooms can be polarizing for some: and I was a real mushroom hater until recently! But when I gave them a try, I realized that portobello mushrooms aren’t the same as those sticky black chunks in cream of mushroom soup. These are juicy, aromatic and totally delicious. I was suspicious of mushrooms for years until I came across portabello. Now I can’t think of anything better to throw on the grill than a portobello mushroom burger! And don’t worry if you don’t have a grill, a roasted portobello is just as good!
For this portobello mushroom burger we went for Mediterranean flavors. We made a batch of our easy Basil Nut Pesto and used garden fresh tomatoes to build these burgers. To top it off, the melted provalone cheese makes for a super tasty and filling burger. We were pleasantly surprised at how easy they were to make and even more impressed with the delicious blend of flavors. I think the word “perfection” might have been muttered between bites. Give them a try and let us know if you become a mushroom burger fanatic!
How to Grill Portobello Mushrooms
Portobello mushrooms are very easy to grill. For our Portobello Mushroom Burger, we marinated it in a mixture of balsamic vinegar and olive oil before grilling. Let them sit for about 15 minutes while the grill preheats. Before marinating the mushrooms, be sure to remove the hard stalks: this will make them easier to eat. When the grill is ready, place the mushrooms on the grill and fry on each side until juicy, about 5 minutes. That’s it! For this portobello mushroom burger, we also melted provalone cheese over the top in the last minute of cooking.
