Ingredients
For the Mushrooms and Marinade
- 4 portobello mushrooms
- ⅓ cup extra-virgin olive oil
- 3 tablespoons balsamic vinegar
- 1 tablespoon soy sauce
- 1 tablespoon minced garlic
- 1 teaspoon kosher salt
- ½ teaspoon black pepper
- ¼ teaspoon garlic powder
Instructions
- Prepare the Mushrooms: Cut off the stems from the portobello mushrooms. Use a spoon to carefully scoop out the brown gills from the caps. Gently wipe the surface of the mushrooms with a damp paper towel to remove any dirt or debris.
- Score the Mushrooms: Using the tip of a paring knife, make a ½-inch crosshatch pattern on the tops of the mushroom caps. Ensure the scores are about 1/16-inch deep, which helps the marinade penetrate the mushrooms for better flavor.
- Make the Marinade: In a small bowl, whisk together extra-virgin olive oil, balsamic vinegar, soy sauce, minced garlic, kosher salt, black pepper, and garlic powder until thoroughly combined.
- Marinate the Mushrooms: Place the prepared mushrooms into a large plastic bag or a shallow baking dish. Pour the marinade over them and turn the mushrooms to coat evenly. Allow the mushrooms to marinate for 30 to 60 minutes to absorb the flavors.
- Grill the Mushrooms: Barbecue Method: Preheat your grill to medium-high heat (350 to 400ºF / 177 to 204ºC). Clean the grill grates and grease them using tongs holding a paper towel dipped in oil to prevent sticking. Remove the mushrooms from the marinade and place them cap-side down on the grill. Cover and cook for 4 to 6 minutes. Flip the mushrooms, cover again, and cook for an additional 3 to 5 minutes until tender.
Grill Pan Method: Heat a grill pan over medium-high heat and grease it with oil. Place the mushrooms on the pan and cook for 4 to 5 minutes. Flip and cook for another 2 to 3 minutes until the mushrooms are tender and cooked through.
Notes
- For best results, use fresh portobello mushrooms without blemishes or deep wrinkles.
- Marinating for longer than 60 minutes is fine but avoid exceeding 2 hours to prevent the mushrooms from becoming too soft.
- If you don’t have a grill, a grill pan is an excellent alternative to achieve those char marks and smoky flavor.
- You can serve these grilled portobellos as a meat substitute in sandwiches, salads, or alongside other grilled vegetables.
- Adjust seasoning to taste or add fresh herbs such as thyme or rosemary to the marinade for extra aroma.
