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 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.

I don’t even like mushrooms, but this turned out surprisingly good! Gonna make it again.
Grilling is hard! Mine got burnt. Better luck next time?
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!
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!!!!!
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.
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!
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!
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.
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!
So delicious! I used it as a burger and my friends were super impressed. Yumm!
I don’t understand why anyone would want to eat mushrooms. But my sister loved it. So, I guess it’s ok for mushroom lovers.
I don’t get it either. They taste all rubbery. But some people swear by them, I guess?
Mushrooms are amazing! Full of flavor and nutrients. You should give them another try!
These mushrooms were just amazing! I made them for my family and they all loved it. Will definitely make again!
Grilled portobello is like a vegan burger! Very tasty, I didn’t miss beef at all. 5 stars!
Honestly, i was skeptical. Mushrooms as burgers? Really?? But wow, I was wrong!
Easy recipe, but i forgot the thyme! Still tasted alright, I guess. Next time.
Grilled mushrooms?! Sounds weird but tasted great! Would do again.
Mushrooms are weird, I don’t like them at all… But my cousin loved it.
I didn’t have thyme so I used oregano instead and it was still yum! Thanks for the recipe!
These mushrooms were amazing! So flavorful and juicy! Will make them again.
Easy recipe! But how can you call them portobello? They look like normal mushrooms to me, just bigger!
I tried this, but my mushrooms turned out mushy. What did I do wrong? Got a 2.
Just made these for my BBQ and everyone loved them. A great vegetarian option!
I tried this once but the mushrooms were all soggy. Maybe I marinated them too long? 🤔
Sounds delicious! I love grilling mushrooms, too. What other sides did you serve at your BBQ?
Super easy! Even my kids liked it, and they usually won’t eat anything green. Lol.
That’s awesome! I’ve been trying to get my kids to eat healthier too. This sounds like a great option!
I like mushrooms, but these turned out a bit too chewy for my taste. Maybe I cooked them too long?
Yeah, I think you might’ve overcooked them. Just a few minutes per side does the trick!
Just okay. It was just mushrooms with some seasoning and people are acting like it’s magic. I don’t get it.
Can somebody tell me why we need to marinate them? They taste fine on their own.
Marinating adds flavor! It makes them juicier and more delicious. Give it a try 👍
But why bother? They’re mushrooms, not steak. I think they taste fine without all that fuss.
Way too garlicy! Next time I will cut down on the garlic for sure.
Grilling mushrooms? Never thought of that! But my grill caught fire, now I’m scared to try again. 😬
These mushrooms are so tasty! I grilled them exactly as you said and they came out perfect. My family loved them!
So glad to hear that! Mushrooms are the best! I love grilling them too!
They looked good but I’m not sure if I’d grill mushrooms. They might be too squishy on the grill? 🤔
So easy to make, my kids loved it too! Perfect for summer BBQs! ☀️
I tried this and it was a hit! My kids went for seconds. Thanks for sharing! 😊
This was like… ok. I expected more flavor honestly. Need more spices?
