Ingredients

Mushrooms

  • 8 to 12 large mushrooms

Filling

  • 1 (6 ounce) can minced clams, drained, with 1/4 cup clam juice reserved
  • 1 finely minced green onion
  • 1 beaten egg
  • 1/2 teaspoon minced garlic
  • 1/8 teaspoon garlic salt
  • 1/2 cup Italian-style breadcrumbs
  • 1 teaspoon oregano
  • 1 tablespoon melted and cooled butter
  • 2 tablespoons finely grated Parmesan cheese
  • 1 tablespoon finely grated Romano cheese
  • 2 tablespoons finely grated Mozzarella cheese (for stuffing)

Garnish and Topping

  • 1/4 cup finely grated Mozzarella cheese (for garnish)
  • 1/4 cup melted butter (for garnish)
  • Freshly diced parsley for garnish
  • Fresh lemon wedges for serving

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and lightly oil a small baking dish to prevent sticking.
  2. Prepare Mushrooms: Gently wash the mushrooms, remove the stems, and pat the caps dry. Keep the stems for another use or discard.
  3. Mix Filling: In a mixing bowl, combine the minced clams, green onion, minced garlic, garlic salt, melted butter, and oregano. Add the Italian-style breadcrumbs, beaten egg, and reserved clam juice, mixing thoroughly. Stir in the Parmesan, Romano, and Mozzarella cheeses until well combined.
  4. Stuff Mushrooms: Spoon about 1 1/2 teaspoons of the clam mixture into each mushroom cap, mounding it slightly for a generous fill.
  5. Arrange and Bake: Place the stuffed mushrooms in the prepared baking dish and drizzle with the 1/4 cup melted butter. Cover the dish and bake in the preheated oven for 40 minutes to allow the flavors to meld and mushrooms to cook through.
  6. Add Cheese Topping: Remove the cover, sprinkle the remaining finely grated Mozzarella cheese over the mushroom tops, and return to the oven briefly until the cheese melts and turns slightly golden.
  7. Garnish and Serve: Garnish the stuffed mushrooms with freshly diced parsley and serve warm accompanied by fresh lemon wedges for an added burst of flavor.

Notes

  • Use fresh mushrooms for the best texture and flavor.
  • Reserve mushroom stems to add to soups, sauces, or stuffing.
  • Adjust garlic salt according to your taste to control sodium level.
  • For a richer flavor, use high-quality aged cheeses.
  • You can substitute Italian-style breadcrumbs with gluten-free breadcrumbs if needed.
  • Serve immediately for best taste and texture; leftovers can be reheated gently in the oven.
