Grilled Portobello Mushrooms Recipe (1)

I am SO excited for the grilling season. We’re starting the season a bit early and regardless of the chilly weather, we’ve been grilling for the past week either in the kitchen using our electric grill, and my trusty cast iron grill pan. Or in the backyard using our outdoor grill

We’ve been making all sorts of easy grilled kabobs, sides, and even desserts. I’ve been loving these grilled chicken kabobs and veggie kabobs, they’re so quick, easy, and taste wonderful. Baked potatoes on the grill or Pearl Couscous Salad will make an easy tasty side dish.

And these portobellos are a MUST on our menu every time we get grilling! Best mushroom recipe, for real. And you can use the mushrooms to make mushroom tacos!

How to Select Portobello Mushrooms

When selecting portobello mushrooms at a grocery store, look for caps that are firm to the touch, and uniform in color. Spotty mushrooms are most probably old.

Their texture should be firm and dry, and definitely stay away from slimy mushrooms! There are brown and white portobello mushrooms, the difference between the two is the taste. The brown portobellos are earthy, while the white ones have a delicate mild flavor.

Prepare the Portobello Mushrooms

I usually remove the stalks for easier grilling. Using your fingers gently twist and pull the stalks and they should come right off. For super fresh mushrooms, you’ll have to use a small paring knife to help you remove the stem.

To clean the mushrooms, use a clean paper towel and gently rub off any dirt from the caps. I don’t remove the gills as they add a lot to the flavor, and I only remove them when I’m stuffing the mushrooms.

Easy Grilled Portobello Mushrooms

All you need to make this recipe is portobello mushrooms, and the marinade ingredients.

The marinade is so simple and easy, it enhances the flavor but does not overpower the earthiness of the mushroom.

Portobello Mushroom Marinade

To make the marinade, you will need balsamic vinegar, olive oil, garlic granules, fresh rosemary, salt, and pepper.

Balsamic vinegar adds a lovely tang to the mushrooms, and rosemary complements the flavor of the mushrooms with a hint of freshness. The reason why I use garlic granules instead of fresh garlic is that fresh garlic can get burnt while grilling.

Whisk all of the ingredients in a small bowl until well combined.

Marinate the mushroom caps in the marinade, and using a basting pastry brush, brush the marinade over them so that they’re well coated.

How to Cook Portobello Mushrooms

You don’t need to worry about any internal temperature since there’s no food safety concern here. So get your grill pan, or use the outdoor grill and place your mushrooms on the grill cap side down, and grill them for 3-4 minutes or until they look done to you.

As the mushrooms are being grilled, I recommend brushing over the leftover marinade to get more flavor. Once the caps get the awesome grill marks, flip them over and cook for 3 more minutes. And that’s it, your portobello mushrooms are ready to be served!

Another method would be to roast the mushrooms on a baking sheet, the result won’t be the same (no grill marks or smokey flavor) but it will still be good!

How to Serve Grilled Portobello Mushrooms

  • Serve as a side with other grilled foods such as grilled meats, and kabobs.
  • Use them as patties in burgers. Top with your favorite cheese, lettuce, tomato, red onion slices, and serve in a tasty toasted bun. The earthy flavor of the mushrooms makes them so perfect to work as patties in burgers.
  • Make stuffed portobello mushrooms by stuffing the grilled mushrooms with a mixture of cheese, herbs, and breadcrumbs, place on a sheet pan and bake for a few minutes.
  • For a meat-free meal, serve with turmeric rice, and a side salad.

Storing Tips

I recommend consuming these mushrooms on the same day, but if you have leftovers then store them in an airtight container in the fridge for up to 2 days.

You can reheat the leftover portobellos if you like, but I serve them cold the next day.

How to prepare and cook portobello mushrooms? ›

Heat a grill or a large skillet over medium heat (about 350 to 400 degrees F). Brush the grill with oil to prevent sticking. Remove the mushrooms from the bowl, shaking off any excess marinade and reserving the marinade for basting. Cook on each side for 3-4 minutes, or until caramelized and deep golden brown.

Should I remove the gills from portobello mushrooms before grilling? ›

How to Clean and Prep Portobello Mushrooms. The stems of large portabella, while technically edible, can be woody and fibrous and are usually discarded (or used to flavor stock). Likewise, the dark black gills can be eaten, but they'll turn your food a nasty, murky, scuzzy brown, so it's best to scrape'em out.

Are grilled portobello mushrooms healthy? ›

Mushrooms also contain high amounts of antioxidants which can help reduce inflammation, improve cardiovascular health and may be protective against cancer!

What we should not do before cooking mushroom? ›

Never salt the mushrooms before cooking. Salt draws out moisture and will therefore make them extremely mushy.

Why can't you eat the gills of a portobello mushroom? ›

When cooked down, the gills release their spores, giving your dish a dark and murky appearance and obscuring other, more vibrant ingredients. This may not seem significant, but we eat with our eyes first—a dull looking dish can prime our palates to expect dulled flavors.

What liquid to cook mushrooms in? ›

Olive Oil + Butter.

Sautéed mushrooms with butter have their benefits, but so do sautéed mushrooms with olive oil. I use both oil and butter for a dynamic duo that pairs searing (oil) with rich, satisfying flavor (butter). (I also use both in my Sauteed Spinach.)

What to pair with portobello mushrooms? ›

What is the black stuff on portobello mushrooms? ›

Whether or not you remove mushroom gills depends on what you're cooking, and if you like how they taste. The main objection to mushroom gills is one of aesthetics: If left on, they can turn your dish dark and murky, and they tend to have a stronger, mustier, slightly bitter flavor, depending on how fresh they are.

Do you wash mushrooms before grilling? ›

To maintain a mushroom's texture, you'll want to rinse them, instead of soaking them. Then, immediately after rinsing, lightly pat the wet mushrooms with a paper towel or a lint-free cloth to remove excess water. In many instances, your mushrooms may only need a gentle brushing to remove any excess dirt or debris.
