Grilled Portobello Mushrooms are my family’s latest favorite grilled food!! You can serve them as a side dish to your favorite grilled meats, chicken etc. Or you can supplement your meatless meals with these grilled mushrooms. Because of their shape, they’re perfect in a burger or sandwich too!!
We spend a lot of time outdoors here in Florida. So we not only love to grill mushrooms but also love to makes these other grilled side dishes: grilled eggplants with sauce, grilled mini peppers or grilled shishito peppers.
How To Prep Portobello Mushrooms?
Short answer, I cut the stems and leave the gills in.
My favorite way is to add all the ingredients over the mushrooms, brush them over to distribute the flavors than let marinate for half an hour. Use a brush to spread all the ingredients over the mushrooms. Most times I eyeball the ingredients for this recipe.
How To Serve Portobello Mushrooms?
I love serving grilled mushrooms as a side dish. You can add leftovers to a frittata the next day or any chicken dish. My favorite way to serve portobello mushrooms though is in a burger or sandwich. Even though we are not vegetarians, we enjoy meatless meals few times a week especially in summer time.
Use an artisan roll or brioche burger bun. Layer with mayo, lettuce, cheese, portobello mushroom, tomato, mustard and any other ingredients you like. This has been on repeat for few weeks in my house this summer.
I keep the ingredients simple but you can add more flavor if you like. I add salt, pepper, olive oil, oregano and balsamic glaze to the mushrooms. Then I garnish with parsley!!
Note: If you can get Mediterranean Sea Salt, use it on anything you grill. You’ll thank me later:). At least I do feel it makes a difference in flavor.
Additional ingredients you can use in the marinade according to taste: minced garlic, lemon juice, soy sauce, paprika etc.
Recipe as is fits Mediterranean Diet standards, it’s vegan and makes great plant based meals if that’s your eating lifestyle.
If it’s too hot outside to fire up the grill, these mushrooms grill great on cast iron grill pan as well. Once the pan is hot, then add marinated mushrooms and grill for about 3-4 minutes on each side. Brush occasionally the remaining marinade on top.
Grilled Portobello Mushrooms
- 4 Portobello Mushrooms
- 2 tbsps olive oil extra virgin
- 1 tbsp balsamic glaze
- 1 tsp dry oregano
- 0.5 tsp sea salt adjust to taste
- 0.5 tsp cracked black pepper adjust to taste
- 1 tsp dry parsley (for garnish, optional)
- Clean portobello mushrooms and prep them. Remove stems and leave the gills in (some people don't like gills, so remove if that's applies to you).
- Place the mushrooms in a platter. Drizzle the olive oil over them. Add oregano, salt and pepper. Use a brush to spread oil and herbs over the mushrooms.
- Finally add balsamic glaze and brush again. Let the mushrooms marinate with olive oil, herbs, salt, pepper and balsamic glaze for about 30 minutes while you set up the grill.
- Grill the mushrooms for about 3-4 minutes on each side. Sometimes I allow for an extra minute when mushrooms are gills up because I love the top to be extra grilled.
- Garnish with parsley on top and serve as a side dish or on burgers and sandwiches. Enjoy:)
- I usually grill in multiples of 4 (my store sells 4 portobello mushrooms in one package) and we are a family of 4 so very rarely I have leftovers. But when I do I store in the refrigerator for next day. Use leftovers in omelettes or frittatas.
If you marinate the mushrooms for about half an hour before grilling, they’ll absorb some of the flavors from the marinade. However, you can just brush all the ingredients over the portobello mushrooms caps and set to grill if you’re in a hurry. Brush few more times as you are grilling.
Short answer, about 3-4 minutes each side. However, grilling time depends on how hot the grill is and you have to adjust accordingly. On a gas grill, I usually grill about 3-4 minutes each side. On a charcoal grill, I grill the mushrooms for 5 minutes each side as I tend to put them on the sides where there’s less heat. Also, on a cast iron grill pan, I usually grill about 4 minutes each side after pan has heated.
