The Best Portobello Mushroom Burger recipe
Summer is here! I'm also looking forward to getting back in the kitchen and first up is my absolutely divine twist on a burger using a big juicy, perfectly marinated portobello mushroom... in fact, this just might be the best Portobello Mushroom Burger recipe you'll ever try!
This recipe is so good because of the simple marinade that includes balsamic vinegar, soy sauce or liquid aminos and the perfect blend of spices like rosemary. My secrets ingredient is adding a bit of classic steak seasoning to the marinade to give it that familiar feeling and taste from meat.
This burger recipe can be left vegan OR you can add a slice of cheese on top. Either way it's one of the simplest ways to have a delicious veggie burger this summer.
Why You'll Love this Portobello Mushroom Burger...
Since I don't eat traditional burgers, I'm always looking for a fun twist on burgers for an easy cookout. Making homemade veggie-based patties is great, but these burgers are even easier because nature does all the work for you. With its size and meaty texture, the portobello mushroom is destined to go on a bun!
These are a 100% crowd pleaser with meat-eaters and vegetarians alike. I made them for the first time earlier this year and the Hubs has been requesting them since.
The big portobello mushroom caps are marinated in a steak-like seasoning blend (no meat, of course, just spices.) It's filled with rich balsamic, salty liquid aminos or soy sauce and even a hefty dose of rosemary. Portobello mushrooms taste amazing on their own but in a rich balsamic marinade, they become magical.
It's really the portobello mushroom marinade that makes this dish the Best Portobello Mushroom Burger recipe.
I think that the combination of flavors really makes this dish appetizing to anyone. They are super approachable and make the entire dish taste so rich.
If you are vegan, you can easily omit the cheese and add avocado. Since I'm not, I added a slice of Muenster, which compliments the flavor of the portobello mushroom. Plus I've found non-veg heads are much more likely to like a vegetarian dish if you put cheese on it.
