Grilled Portobello Mushrooms are the ultimate vegetarian dish that packs a punch of flavor while being simple to prepare. Known for their meaty texture, Portobello mushrooms are ideal for grilling, absorbing smoky flavors and becoming tender with a rich, savory taste. Whether you’re making them the star of the meal or using them as a hearty side, these mushrooms are a delicious, healthy, and satisfying choice.
The beauty of grilled Portobellos lies in their versatility. The mushrooms themselves have a natural umami flavor that deepens when grilled, especially when marinated beforehand. A simple marinade of olive oil, balsamic vinegar, garlic, soy sauce, and a touch of thyme or rosemary enhances their flavor and infuses them with a rich, savory taste. After a brief soak, they’re ready to hit the grill, where they’ll cook to perfection in just a few minutes.
The grilling process adds a wonderful smokiness to the mushrooms, while the inside stays juicy and tender. The texture is so meaty that grilled Portobellos are often used as a substitute for burgers. For a lighter take, serve them as a side dish alongside grilled vegetables, or slice them up and toss them in a salad. For a satisfying main course, place them on a toasted bun and top with cheese, avocado, or even a dollop of homemade basil pesto for a gourmet veggie burger.
Grilled Portobello mushrooms are quick, easy, and packed with flavor, making them perfect for a weeknight dinner or a weekend BBQ. Their earthy flavor and satisfying texture will leave you feeling full and happy, and they’re a great addition to any vegetarian or plant-based meal plan.
Whether you’re grilling them for a casual meal or serving them as part of a more elaborate feast, Grilled Portobello Mushrooms are a crowd-pleasing, flavor-packed dish that anyone can enjoy.

5 stars! 🥇 Me and the family loved it, even the kids who never eat mushrooms!
So glad to hear that your kids liked them! Gotta love a recipe that gets everyone to eat their veggies. 🍄
I don’t even like mushrooms, but this turned out surprisingly good! Gonna make it again.
Grilled mushrooms? Really? It’s just fungus on the grill. Didn’t impress me at all. 😒
These mushrooms turned out amazing! So juicy and full of flavor. Definitely making them again! 🌟
I don’t know about these mushrooms… they sound kinda weird to me. How can they be juicy tho? Aren’t they just gonn be spongy?
I tried this recipe too and they were super yum! I added some cheese on top – totally worth it! 🧀
Grilling is hard! Mine got burnt. Better luck next time?
Delicious! My kids even liked it, and they usualy dont eat veggies. Grilling is the way to go!
I didn’t have thyme so I used oregano instead. Still came out pretty decent! Yum!
These mushrooms are DELICIOUS! I can’t believe how much flavor they have. Thanks for this easy recipe!
These mushrooms were delicious! I added some cheese on top and it took them to another level!
Cheese on mushrooms? That’s a genius idea! Can’t wait to try it out myself.
I think grillin mushrooms is stupid. Why not just fry them in a pan? Less mess.
This is the best mushroom recipe I’ve ever tried! So flavorful! 😍
I used white vinegar instead of balsamic and they were still good! Get creative!
Well, I tried it and it was ok, doesn’t compare to real meat tho lol.
Yum! The balsamic vinegar really makes em pop! Will definitely make again!
So good! I made these for a party and everyone loved them. Balsamic is life!
I thought the vinegar was too strong! Did you use the same amount?
These mushrooms are delicious! I made them just like the recipe says and my family loved them. 5 stars!
Yummy! I love grilled mushrooms too, but I just toss them on the grill without marinating. They still taste great!
Too much garlic for my liking. I would cut down on that next time.
I don’t know, I think the garlic is what makes it awesome! Maybe try using less but not too little!
Mushrooms taste like dirt. Never again!!!!!
Imo, the thyme was too much, maybe just a pinch next time? Also, what’s the point of vinegar in a mushroom? 🤔
Not bad but I halved the oil and it still was oily. Might not make again.
Too much balsamic!! I couldn’t finish it..
I love grilling but this made my kitchen smell like a science experiment gone wrong.
I couldn’t find portobello, so used button mushrooms. It totally didn’t taste the same. 2 stars.
Grilled ‘shrooms! Yum! My kids didn’t even know they were eating mushrooms. 🙌
Grilled mushrooms? Sounds weird! I don’t think my kids would eat them even if I tried. 🤔
That’s awesome! I love when kids enjoy healthy food without knowing it. What a sneaky way to get them veggies! 🌱
Is it just me or are Portobello mushrooms kinda like meat? I put cheese on top and wow!
Totally! They really do have a meaty texture. Love them on the grill with cheese! Yum!
Isn’t balsamic vinegar a bit too strong for mushrooms? I prefer a lighter marinade.
Holy moly! Best veggie burger ever! I used them instead of meat and was blown away! Highly recommend!
Wow, I can’t believe a veggie burger can taste that good! Gonna try this recipe for sure!
I giv it a 3, they were kinda rubbery. Maybe was my grill idk??
I’ve had that happen too! If your grill’s too hot, they can get rubbery. Maybe try a lower temp next time?
Did you know portobellos are just big button mushrooms?? I learned that recently lol.
Good simple rec! I added cheese on top late in cooking, was delish!
Quick and easy! My kids actually ate them, shocker! Will make again for sure. 😊
I don’t know… mushrooms? My kids only eat chicken nuggets. But maybe I’ll give it a shot.
That’s awesome to hear! Getting kids to eat healthy can be tough. Glad they liked it! 🍄
I dunno, they were kinda chewy and bland. Maybe I did something wrong?
I think the marinade needs a bit more salt if they were bland. Also, make sure to let them marinate longer next time!
Yum! Had them on a bun like a burger, delicious! My kids even liked it!
That sounds awesome! Grilled mushrooms on a bun? I gotta try that!
I don’t know… mushrooms as burgers? Sounds weird to me.
Don’t get why people like mushrooms, but my partner loved these. I guess if you like mushrooms, this may be for you.
I think mushrooms are amazing! They add so much flavor. If you don’t like them, that’s okay, more for the rest of us! 😂
I can’t stand mushrooms either! 🤢 But if your partner liked it, maybe you can just make it for them. Not everythin has to be for everyone.
I didn’t have thyme, so I used rosemary. Still turned out great! Enjoyed them on burgers, yum!
I love how simple this recipe is! Made it for my vegan friends and they devoured it! Will try again!
I know right! It’s super easy and delicious. I made a version for my non-vegan family, and they loved it too!
Not sure if this really sounds that good, mushrooms can be kinda weird. Maybe I’ll just stick to regular burgers.
I tried this and it was just bland. Not enough flavor for me, maybe I did something wrong. Didn’t wow me.
Had trouble getting the mushrooms to cook evenly. One side was a bit burnt while the other was undercooked. Anyone else have this issue?
Gotta say I was skeptical but these mushrooms made a great burger! 5 stars from me!
Had to substitute thyme with basil. Still turned out decently good! Next time I’ll get thyme tho.
5 stars! I just love the balsamic marinade, it’s a game changer.
I agree! The marinade is just fantastic!
