  • 4 large Portobello mushrooms
  • 1/4 cup balsamic vinegar
  • 1/4 cup olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon dried thyme (or 2 teaspoons fresh thyme)
  • Salt and black pepper, to taste
  • Optional toppings: sliced tomatoes, fresh basil, mozzarella cheese


Make Your Marinade -In a small bowl, whisk together balsamic vinegar, olive oil, minced garlic cloves, dried or fresh thyme leaves (optional), salt, and black pepper until evenly mixed This will serve as your marinade!

Clean the Portabello mushrooms-Use a damp paper towel or mushroom brush to gently cleanse Portabello mushrooms of any dirt or debris, while avoiding washing under running water because this could expose too much moisture for them to absorb.

Remove Mushroom Stems-Carefully cut or twist off any tough mushroom stems to save them for another recipe, or simply discard.

Marinate Mushrooms– Begin by placing cleaned mushrooms gill-side up in a shallow dish. Pour the marinade over them evenly, using a pastry brush if necessary to spread out evenly across their surface.

Let Them Marinate-Cover the dish with plastic wrap or a lid and place it in the fridge for at least 30 minutes, but up to two hours will enhance flavor!

Preheat Your Grill-Before preheating your grill to medium heat (between 375-400degF or 190-200degC), ensure it reaches medium-high temperatures of approximately 375 to 400degF or 190 to 200degC.

Portobellos on the Grill– We Carefully place marinated mushrooms gill-side down onto your grill, and grill for approximately four to five minutes per side or until tender and lightly charred – basting with more marinade while grilling is optional!

Add Toppings (Optional)-For added flair, feel free to add toppings like tomatoes, fresh basil leaves or mozzarella cheese during the last few minutes of grilling. Be sure to cover your grill to melt any cheese you are using

Serve-Once the mushrooms have reached your preferred level of doneness, remove them from the grill. Use them as part of a main course, on salad, as burger substitutes or any other way you see fit – the possibilities are limitless!

Tips: For extra flavour, add a dash of fresh lemon juice or a 0sprinkle of grated Parmesan cheese for additional flair.

If you don’t have access to a grill, use a grill pan or stove top griddle instead.

Care should be taken not to overcook mushrooms, as this could make them too soggy; you want a tender yet meaty texture in your mushrooms.

Feel free to customize the marinade according to your tastes by including any desired herbs and spices.
