Ingredients for grilled portobello mushrooms

Portobello mushrooms are what convinced me to stop hating this vegetable (or really, fungus). The meaty flavor you can get when you cook them is unreal! The grill is really the best cooking method for portobello mushrooms because it infuses that smoky flavor, too. All you’ll need is a few ingredients to get massive flavor:

  • Portobello mushroom caps
  • Olive oil
  • Balsamic vinegar
  • Kosher salt
  • Fresh ground black pepper

Top with fresh herbs if you like

No marinading required!

Here’s the big selling point on this recipe: you don’t have to think ahead to marinade these grilled portobello mushrooms. Nope, just sprinkle them with olive oil and balsamic vinegar (see the recipe below) and they’re good to go! Let them sit while the grill is preheating, or you can even do it right before you grill. It’s going to have big flavor either way! See the recipe below for quantities.

How to grill portobello mushrooms (basic steps)

Now: here’s our master technique for grilled portobello mushrooms! One thing to note is that they give off quite a bit of liquid as you grill them. That’s why it’s important to grill gill side up first. The liquid will pool in the cap, and then you can flip it to drain the liquid through the grates. Here’s how to do it (or jump to the recipe):

  • Preheat a grill to medium high heat: that’s 375 to 450 degrees.
  • Prep the mushrooms: Remove the stems and drizzle with olive oil, balsamic vinegar (quantities below).
  • Grill: Place on the grill gill side up, and 10 to 14 minutes, then flip and grill 2 to 3 minutes until juicy and browned.

Serve grilled portobello mushrooms as burgers!

The nice thing about grilled portobello mushrooms: you can serve them as a side dish or as a main dish! Eat them on a bun and they become “portobello burgers.” But make sure to add a source of protein to the sandwich: like cheese! Or serve them with a hearty side filled with plant-based protein. Mushrooms don’t have much protein on their own, so they’re not as filling as a normal burger would be. Here are some ideas on how to serve them:

Scale

Ingredients

  • 4 portobello mushrooms
  • 2 to 3 tablespoons olive oil
  • 1 to 2 tablespoons balsamic vinegar
  • 1/2 teaspoon kosher salt
  • Fresh ground black pepper

Instructions

  1. Preheat a grill to medium-high heat (375 to 450 degrees Fahrenheit).
  2. Clean the portobello mushrooms and remove the stems. Drizzle the gill sides with the olive oil and use your hands to rub all over the mushrooms, including the bottoms. Then drizzle the gill sides with balsamic vinegar, sprinkle with kosher salt, and add several grinds of black pepper.
  3. Place the mushrooms directly on the grill grates gill side up and grill 10 to 14 minutes until tender and juicy. Liquid will pool in the cap. Flip the mushrooms (this drains the liquid into the grates) and cook for an additional 2 to 3 minutes until browned.
