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.
So how do you make zesty vegetarian burgers?

I love portobello mushrooms. My choice of burger whenever I go to Nandos is their portobello mushroom burger or wrap. Will definitely try making the burgers at home when I get these nutritious and filling mushrooms.

Looks delicious except I would have to omit the onion due to a food intolerance. You always share the healthiest recipes!

I'm all over grilled veggies and a mushroom "burger" and I'll take the whole plate of pineapple! Thank you for linking up with us for Meatless Monday, hope you are having a great 4th!
Me too! Thanks Sarah! Hope you had a good holiday.
I love love love portobello burgers! This looks awesome!
Alisa @ Go Dairy Free says
Those look so satisfying! I haven't been into veggie burgers much lately as they are often too grainy (like eating bread on bread on bread) or beany. Mushroom burgers sound perfect right now.
Yes! And they are actually so much easier than assembling your own burger. Just swap the cheese for avocado to make dairy-free.
I'm glad you've been having a lot of fun even though it sounds super hectic! Yay for mushroom burgers! This looks all sorts of amazing and I love all the pretty colors in it! :]
Thanks Farrah! I love to put all the colors on my food.
Natalie @ A Fit Philosophy says
This looks so delicious! I love a good burger, but this is a great option for when I'm not wanting to eat meat! I love any kind of mushroom 🙂
Me too Natalie! Such an easy vegetarian meal.

Mary Ellen @ VNutrition says
Another great burger choice for the 4th! Pinned your picture. 🙂
I stayed at the outer banks with my husband's family who live in Charlotte. We haven't gone for a while but it was so fun.
I'll still hoping for wild horse pictures. 🙂

Susie @ SuzLyfe says
Omg, It has been far, far too long since I've had a portabello mushroom (I don't order them at restaurants because you know they drown them in stuff my tummy can't handle). But I love to douse my in balsamic and then grill or pan sear.
Thanks for the reminder, Julie! And I'll be sure to try your version!
It's so good Susie! Love these burgers!
