  • 6 large Portobello Mushrooms
  • 4 tbsps. pesto sauce 2 tsps. for each mushroom
  • 1 1/2 cups of shredded mozzarella cheese
  • 3/4 cup fresh shredded
  • 2 tbsps. of olive oil
  • 1 tsp. salt to taste
  • 1 tbsps. fresh cracked black
  • 1 cup cherry tomato cut in halves


  • Clean mushrooms and remove stems.
  • Place on a non-stick sheet pan and brush each side of the mushroom with olive oil.
  • Sprinkle some salt and pepper on each side.
  • Place 2 tsps. of pesto sauce into each mushroom and brush evenly.
  • Fill each mushroom with 1/4 cup of shredded mozzarella cheese and then sprinkle some fresh basil on top of the cheese.
  • Add a few pieces of tomatoes, leaving spaces between them. Fill those spaces with the fresh shredded mozzarella cheese. Top with more chopped basil leaves.
  • Bake in a preheated 375 degree oven for 12 minutes then turn on the broiler to broil the top for 1-2 minutes until the cheese obtains a golden color.
  • Remove from heat and serve.


  • Thoroughly pat dry portobellos with paper towel.
  • If you decide to do use all fresh mozzarella cheese, I would suggest you keep using a paper towel occasionally to remove the excess water you get on the top of the cheese. I personally love using fresh mozzarella because it melts out so nice and it's a lot yummier.
  • Use a preheated oven.
  • Cook until you see a nice golden color starting to show up on the cheese.
  • You can always drizzle some concentrated balsamic vinaigrette on top, but that's totally optional because that does contain quite a bit of sugar sometimes depends on the type you use.
