Grilled Portobello Mushroom Steaks
Are you excited for summer? The grilling season is here and in my opinion, there is nothing better than grilling vegan food with friends! Don’t you think so too?! Today I have the perfect vegan side dish for you. I am talking about these grilled Portobello mushroom steaks which will make your mouth water.

How To Make The Best Portobello Steaks?
Check the following step-by-step instruction photos below:
- First, remove the mushroom stems.
- Wipe the mushrooms clean (I used a brush).
- Add garlic, soy sauce, balsamic vinegar, oil, and all spices to a shallow baking dish.
- Stir with a spoon or whisk.
- Add Portobello mushrooms.
- Brush with marinade on all sides.
- Marinate for at least 10-15 minutes (or longer).
- Cook on the grill or in a skillet on the stovetop for 5 minutes (each side).
Only 10 Ingredients
You only need 10 ingredients to make these flavorful mushroom steaks. The main ingredient is, of course, Portobello mushrooms. Mine weren’t nicely shaped but I don’t care because even ugly produce tastes delicious, right?!
I used a mixture of gluten-free low-sodium soy sauce (you can use tamari, coconut aminos, or regular soy sauce), balsamic vinegar and a spice mix. The spices are actually up to you. If you aren’t a fan of cumin, just leave it out. Do you love smoked paprika? Use more of it. Love it spicy? Add cayenne pepper!
You can also use garlic powder instead of fresh garlic. Both work fine! Fresh herbs like thyme or rosemary are a nice addition as well. Feel free to use any fresh or dried herbs of choice. If you have liquid smoke, add a little of it! It adds a wonderful smoky flavor.
I used olive oil but any other oil will work as well.
Cook or Bake the Portobello Steaks
Cook the Portobello mushroom steaks in a large skillet on the stovetop or on the grill. Another option would be to bake them in the oven. I would suggest 25 minutes at 400 degrees Fahrenheit (200 degrees Celsius). Gently flip after 15-20 minutes.
How To Serve Portobello Steaks?
I served these grilled mushrooms with my favorite creamy vegan potato salad. It’s really the best side dish I can imagine, however, you can, of course, serve them with any other dish. Some ideas would be oven baked potato wedges with guacamole! Or what about roasted homemade gnocchi?
The possibilities are endless. Here you can check out more vegan side dishes which I love! You could also make burgers and use the grilled mushrooms as vegan patties!
