Servings 4


  • 1 cup mozzarella cheese grated
  • 1 clove garlic finely grated
  • 6 basil leaves finely chopped
  • 1/4 cup parsley finely chopped
  • 1 tablespoon butter at room temperature
  • 4 portobello mushrooms
  • 4 tablespoons avocado oil
  • 1 teaspoon salt
  • 1 teaspoon ground black pepper
  • 4 cherry tomatoes sliced
  • 1/2 cup Panko breadcrumbs


  • Preheat your grill to 350 degrees F.
  • Begin by preparing the filling, add the mozzarella, garlic, basil, 2 tablespoons parsley, and butter to a bowl. Mix until combined and set aside.
  • Next prepare the mushrooms. To prepare the portobello mushrooms, remove the stem and use a teaspoon to remove the dark gills from the mushroom. Discard the stem and gills of the mushrooms.
  • Combine the avocado oil, salt and pepper in a small bowl and mix to combine. Use a pastry brush to brush the oil mixture all over the inside and outside of the portobello mushrooms.
  • Once hot, add the mushrooms to the grill, hollow side down. Cover and let cook for 5-6 minutes, or until the inside of the mushroom has softened and has light char marks. Remove the mushrooms for the grill and place on a plate.
  • Divide the cheese filling evenly amongst the four mushrooms, placing it in the centre of each hollow mushroom cap. Press the filling down gently to ensure it does not fall out.
  • Top each mushroom with 3-4 slices of cherry tomato, followed by a sprinkle of breadcrumbs.
  • Return the mushrooms to the grill (filling side up), cover and let cook for another 5 minutes, or until the bottom of the mushroom has softened and all the filling has melted.
  • Remove from the heat and garnish with an extra sprinkle of chopped parsley. Serve and enjoy!



You can also bake these mushrooms in the oven. Preheat your oven to 400 degrees F and bake the mushrooms (hollow side down) for 15 minutes, until softened. Then flip the mushrooms and add in the filling and breadcrumb topping. Return the mushrooms to the oven and bake for another 10 minutes, or until the filling has melted.
