Meaty and full of umami-rich flavor, these grilled portobello mushrooms are as versatile as they are delicious. Tuck them into a bun with your favorite burger fixings for a hearty, plant-powered portobello mushroom sandwich, or serve them straight from the grill with a baked potato or grain and a crisp salad for a satisfying steak-style supper. Either way, this simple garlic- and ginger-infused soy sauce marinade brings out their savory depth!

(5 from 5 votes)The BEST portobello recipe I have ever tried!
I just made this for dinner tonight and it was so good! Very quick and easy to make. I will definitely be making this again.
Simple, easy, and now a favorite!
Best marinade for a portobella I have had so far! Delicious!
I don’t have a grill. Are there baking/broiling instructions?
What can I use to substitute for Brown Rice Syrup? (it's not available in my small town)
Soak dried fruit in hot water or overnight in regular water. Dates are most common but any dried fruit will work. Then blend it up (you can put the soaking water according to how thin or thick you like it) and you have a paste there!
You can also use maple or date syrup
Do you scrape out the gills of the portobello mushrooms?
Yes, definitely
I never scrape it. Best stuff in it.
This is amazing!
Do you remove the stems from the mushrooms?
Yes. The ingredient list states "stemmed", which means to remove the stems. :)
