  • 2 large Portobello mushroom caps
  • 2 tablespoons extra virgin olive oil
  • ¼ teaspoon garlic powder
  • Kosher salt and fresh cracked black pepper to taste
  • pizza sauce (recipe to follow)
  • ½ cup mozzarella cheese shredded
  • ½ cup parmesan cheese shredded
  • ¼ cup black olives (optional)
  • 2 tablespoons fresh basil leaves chopped optional

Pizza Sauce

  • 1 cup tomato sauce
  • ¼ teaspoon dried oregano
  • ¼ teaspoon dried basil


  • Preheat oven to 400 degrees F.
  • Prepare the pizza sauce: In a small saucepan over low heat; mix together tomato sauce, oregano, basil. Heat until warmed through.
  • Meanwhile, wipe down the mushroom caps with a damp paper towel to remove any dirt. Gently scrape off the gills inside the mushrooms caps with a spoon.
  • In a small bowl, combine the olive oil, garlic powder; season with salt and pepper, to taste. Brush the caps (all over) with the olive oil mixture.
  • Line a baking sheet with foil, arranging the mushrooms on it stem side up.
  • Spoon 2 tablespoons of the pizza sauce into each mushroom.
  • Top each cap with mozzarella cheese.
  • Add olives and artichokes and fresh basil along with any other topping of your choice. Sprinkle with parmesan cheese.
  • Bake the mushroom caps for 15 minutes or until the cheese starts bubbling. Turn on broiler and broil until cheese is golden brown, about 5 additional minutes.


Removing the gills is totally optional. You can leave them in, they are edible. However, you will see a dark liquid cook out which may spoil the appearance of the pizzas.
