Prep time


Cooking time






  • 4 large portabella mushroom caps

  • 1/4 cup balsamic vinegar

  • 2 tablespoons olive oil

  • 2 cloves garlic, minced

  • 1 teaspoon dried thyme

  • 1 teaspoon dried rosemary

  • Salt and pepper to taste

  • Fresh parsley (for garnish)


  • Clean the Mushrooms: Start by cleaning the portabella mushroom caps. Gently wipe them with a damp paper towel or a mushroom brush to remove any dirt. Avoid rinsing them with water as mushrooms can absorb too much moisture.
  • Prepare the Marinade: In a small bowl, whisk together the balsamic vinegar, olive oil, minced garlic, dried thyme, dried rosemary, salt, and pepper. This flavorful marinade will infuse the mushrooms with a burst of taste.
  • Marinate the Mushrooms: Place the cleaned mushroom caps in a shallow dish, gill-side up. Pour the marinade over the mushrooms, making sure to coat them evenly. Allow them to marinate for at least 30 minutes, or for even more flavor, let them sit in the fridge for up to 2 hours, turning them occasionally.
  • Preheat the Grill: Preheat your grill to medium-high heat, around 375-400°F (190-200°C). If you’re using a charcoal grill, make sure the coals are hot and covered in white ash.
  • Grill the Portabellas: Place the marinated mushrooms on the preheated grill, gill-side down. Grill for about 5-7 minutes on each side, or until the mushrooms are tender and have grill marks. Baste with any remaining marinade during grilling.
  • Serve: Transfer the grilled portabella mushrooms to a serving platter, gill-side up. Garnish with freshly chopped parsley for a burst of color and freshness.
  • Enjoy: Serve your vegan grilled portabella mushrooms as a main dish with a side salad, on a bun as a burger substitute, or sliced as a topping for a variety of dishes. They’re versatile and incredibly tasty.


  • Choose Fresh and Large Portabella Mushrooms: The key to a fantastic grilled portabella mushroom dish is selecting the right mushrooms. Look for fresh, large portabellas with firm caps. These mushrooms will be more substantial and absorb the marinade better, resulting in a more flavorful and satisfying meal.
  • Enhance the Marinade with Extra Flavorings: While the basic marinade in the recipe is delicious, feel free to get creative with additional flavorings. Add a dash of soy sauce or tamari for a savory kick, a pinch of red pepper flakes for some heat, or even a squeeze of lemon juice for brightness. Experimenting with the marinade can take your grilled portabellas to the next level.
  • Precook the Mushrooms Slightly: If you want to ensure your portabella mushrooms cook evenly and become extra tender, consider lightly precooking them in the oven or on a stovetop skillet for a few minutes before grilling. This will reduce grilling time and help avoid undercooking or overcooking.
  • Add Vegan Cheese or Toppings: Elevate your grilled portabella mushrooms by adding some vegan cheese or other toppings. During the last few minutes of grilling, place a slice of vegan cheese on each mushroom cap and close the grill lid to melt it. Alternatively, top your grilled mushrooms with fresh avocado, sliced tomatoes, or arugula for added flavor and texture.
  • Serve with a Complementary Sauce or Dressing: While the marinated mushrooms are delicious on their own, consider serving them with a complementary sauce or dressing. A drizzle of balsamic reduction, a dollop of vegan garlic aioli, or a simple chimichurri sauce can enhance the overall taste and make your dish even more delightful. These sauces can also double as dipping options for added flavor bursts.
