Ingredients
- 12 large fresh mushrooms
- 3 tablespoons melted butter
- 1/4 cup finely shredded mozzarella cheese
- 1 can minced clams, drained (6 oz)
- 1 finely chopped green onion
- 1 large beaten egg
- 2 teaspoons minced garlic
- 1/2 cup italian-style bread crumbs
- 1 teaspoon dried oregano
- 1 tablespoon melted butter
- 3 tablespoons grated parmesan cheese
Instructions
- Step 1: Preheat your oven to 350 degrees F. Spray a baking dish large enough to hold the mushrooms with non-stick cooking spray to prevent sticking.
- Step 2: Carefully remove the stems from the mushrooms and clean each mushroom cap with a dry paper towel. Avoid using water to keep them from becoming soggy.
- Step 3: In a mixing bowl, combine the minced clams, green onion, beaten egg, minced garlic, italian-style bread crumbs, dried oregano, 1 tablespoon melted butter, shredded mozzarella cheese, and grated parmesan cheese. Stir thoroughly to mix all ingredients evenly.
- Step 4: Fill each mushroom cap with 1-2 spoons of the prepared filling and arrange them, filling side up, on the prepared baking dish.
- Step 5: Drizzle the mushrooms with 3 tablespoons melted butter. Cover the baking dish tightly with foil and bake for 20-30 minutes, until the mushrooms are tender.
- Step 6: Remove the foil, sprinkle extra mozzarella cheese over each mushroom, and bake uncovered for 2-3 minutes until cheese is melted and bubbly.
- Step 7: Take the mushrooms out of the oven and allow them to cool slightly before serving. Enjoy!
Tips & Variations
