  • 9 ounces mushrooms
  • 6 ounces clams drained
  • 1 tablespoon green onion chopped fine
  • 1 egg beaten
  • 1/2 teaspoon garlic minced
  • 1/8 teaspoon garlic salt
  • 1/2 cup Italian breadcrumbs
  • 1 teaspoon oregano leaves
  • 1 tablespoon butter melted and cooled
  • 2 tablespoons Parmesan cheese finely grated
  • 1 tablespoon Romano cheese finely grated
  • 2 tablespoons mozzarella cheese finely grated for stuffing
  • 1/4 cup mozzarella cheese finely grated for garnish
  • 1/4 cup butter melted


  • Wash the mushrooms, remove the stems, and pat dry. Save the stems for another recipe. Drain the clams and reserve the liquid.
  • In a mixing bowl, mix together clams, green onion, minced garlic, garlic salt, 1 tablespoon soft butter, and oregano. Add egg, breadcrumbs, and clam juice and mix everything together. Stir the cheeses into the clam stuffing until well blended.
  • Place the clam mixture in each mushroom cavity and make it into a small mound. You should be able to stuff between 8 and 12 mushrooms depending on the size of the mushrooms. Place the mushrooms in a lightly-oiled baking dish. Pour 1/4 cup melted butter over the mushrooms.
  • Cover and place in a preheated oven at 350 degrees for about 35 - 40 minutes. Remove from the oven and sprinkle the mushrooms with freshly grated mozzarella cheese. Pop them back in the oven until the cheese is just slightly melted.
  • Garnish with freshly diced parsley.
