Grilled Portobello Mushrooms make a great vegetable side or can serve as the centerpiece in a vegan burger.
Grilled Portobello Mushrooms
by Sue Lau | Palatable Pastime
This week, as part of the Sunday Supper movement, I have set about to create a recipe using five ingredients or less, where water, salt, pepper and oil are designated as “freebies”. I use only five, since I figure that to be fair, the freebie oil should be a small amount for coating cookware or brushing a grill. The amount I list is a bit more than that, since it is part of a marinade. No water is needed in this, and if you prefer, feel free to add a little salt and pepper but I didn’t find myself needing it. As well, any ingredients used to make a mushroom burger are strictly optional, but include those because that type of sandwich makes a perfect sandwich at a cookout for my vegan friends and family.
Mushroom Grilling
The great thing in this recipe is obviously the simplicity. I can throw this together in about 5 minutes and let it sit in the marinade for the afternoon, pulling them out in time to grill. And the cook time is short- I cook until I can easily slip a paring knife in and out of the center where the stem was, since that is the thickest part. That it is tender in the center actually trumps the grilling time, since some mushrooms are just a bit bigger or thinner than others, so times vary.
I do really love how fast these are to make. It seems that over the past month or so I have been extremely busy with this or that, and it has left much less time for cooking dinner. In times like these, I often find myself turning to easy to grill items, and in this case, I grilled these with some cooked bratwurst, and also grilled corn.
Grilled Mushrooms with Grilled Brats
Also, I love getting outdoors to cook. Can I whine that the fan on my a/c is acting up again? Second time in a month, and it won’t be until tomorrow that the repairman returns to cover his work. So life in the kitchen itself has been minimal, even though it is my “zone” so to speak. I have a story about one of my cats, Jackie Panzer, who is terribly frightened by thunder. And we have had a few of those recently (I had some major damage to my patio area from storm wind microbursts which tossed a 7 foot bay leaf tree which weighs, oh, I don’t know, maybe 150-200 pounds with pot, several feet across the patio, and yet a 1 pound pot of herbs a few feet away sat undisturbed). That same storm flipped cars up in the Beavercreek Ohio area. I might normally feel terribly unlucky considering the damage, but my car is quite all right. But anyway, with Jackie, he hides. And if he can’t find me, he will hide right in front of the stove where he expects to find me. Poor little blighter. I wish I could offer him more comfort and assurance, but I can’t always be right there!
Grilled Portobello Mushrooms

Inactive prep (marinate): 4-6 hours
Active prep & cook time: 15 minutes
Ingredients:
- 2 large portobello mushrooms
- 1/4 cup olive oil
- 1/4 cup balsamic vinegar
- 3 cloves garlic, minced
- 1 tablespoon chopped fresh rosemary
Method:
- Whisk together the olive oil, balsamic vinegar, garlic and rosemary in a small bowl.
- Brush off mushrooms and trim the stem close to the cap. You can rinse these if they are especially soiled since they will be going into the marinade straight away.
- Put mushrooms and marinade in a ziplock bag, squeezing out excess air, and refrigerate for several hours.
- Prepare outdoor grill (gas or charcoal) and grill caps 10 minutes, or until fork tender in the center, turning once. You can baste with extra marinade if you wish.
- Serve these as a vegetable side dish, or put them on sandwich buns with burger type toppings (lettuce, tomato, onion, etc.)

Moroccan Stuffed Peppers with Couscous
Such a great thing to make when grilling burgers and have vegetarian friends.
Yes, they are! Just grill them separate if cooking where meat was upsets them. They are easy enough to grill first.
I seriously love portobellos! I love meat, but I like to go meatless every once and a while and mushrooms are so meaty and low cal….this is so something I will make!
Thanks, hope you enjoy!
Your grilled portobellos sound perfect! I’m loving all the easy recipes this week—perfect for a busy summer!
They definitely save time!
Why I don’t think to make portobello mushrooms more often considering how much I actually enjoy eating the is a mystery to me. I don’t have an outside grill but I’ll bet my stove top grill would work for this recipe as well.
You could do them with a panini press. or even roast them too.
We love grilled portobellos. Thanks for the reminder that we need to get some!
They are a grilling fav here!
I’ve tried this grilled mushroom before in a restaurant, and that is really delicious. But now I want to try to prepare this at home, andmy family would loveit.
Thanks. They are really quite simple to make!
omg these mushrooms sound pretty delicious. It’s finally grilling season here in WNY. Will have to give this a try 🙂
Thank you!
I love portabella burgers. Great choice for this weeks Sunday Supper.
Thanks!
My mom loves portobello mushrooms so much! I have only tried them once and I really need to give them another try.
They are like full sized crimini mushrooms if you have had those. We love them.
Poor little Jackie <3 Our kitties get scared with firecracker displays….We could definitely stand some thunder and rain in CA! Anyway, Sue, your grilled Portobellos look yummy…and perfect whether vegetarian or not =)
Thanks.
They look really awesome and delicious! Hopefully I can come up with my own version of this!
There are a number of different types of marinades suitable for mushrooms, depending on the flavor profile you want.
Mm, that looks delicious. I could have this everyday if Portobello mushrooms aren’t too expensive here.
I find beef more expensive here. You could also use crimini and put them on kebabs. They are not much more expensive than white mushrooms and sometimes the exact same price.
Awww storms really can be scary. The mushrooms do sound great. Thank you for sharing.
Thanks. And my cat thanks you. He adores adulation, but I think all cats do!
Someday I’ll be brave enough to try a mushroom burger. I am just now coming around to adding mushrooms to some meat dishes, but I chop them up super tiny! When I can eat a mushroom burger, I’ll know that mu taste buds have officially grown up. (=
They are very meaty! Grilled veggies sometimes make the best sandwiches!
I adore portobellos, they are so meaty you don’t miss the beef!
And beef is so expensive lately!
I love grilled mushrooms. I have never thought of grilling a portebello on the bbq. Off to try it.
I hope you enjoy it! We love grilled mushroom anything.
My husband’s been wanting to try this and I think even my almost-11-month-old would love it.
Thanks so much!
Perfect for a summer grill party!
Thanks!
This is my favourite summer recipe when it comes to grilling!
Thanks!
