  1. Preheat oven to 350 degrees F (175 degrees C). Lightly grease a medium baking sheet.
  2. Remove stems from mushrooms. Reserve and chop approximately 1/2. Arrange mushroom caps in a single layer on the prepared baking sheet so that the edges of the caps touch one another. Set aside.
  3. In a small saucepan over medium heat, melt 1/2 cup butter. Place reserved, chopped mushroom stems in the pan, and slowly cook and stir until soft. Stir in the flour to coat mushroom stems. Mix in green onions, sherry, minced clams and 1/2 their reserved juice (discard remainder), garlic, bread crumbs, pepper, Italian-style seasoning and bacon bits. Continue cooking approximately 3 minutes, until all ingredients are well mixed. Remove from heat and stir in Romano cheese. Allow mixture to cool approximately 5 minutes.
  4. Fill the mushroom caps generously with the mixture. Drizzle with melted butter.
  5. Bake in the preheated oven 20 to 25 minutes, until lightly browned. Serve with lemon wedges.

I loved this recipe! I made these for a large group and it was the first time I made stuffed mushrooms in my life. Someone asked me what store I bought them from because they tasted too good to be homemade??? Anyway, an important note for those going to make this. #1 - Use REAL bacon bits, NOT the crunchy bacon flavored salad toppings, because that is all I had and the bacon flavor was a little too strong that way. #2, the recipe takes a little more time than it says, but highly worth it - just give yourself some more time. #3 Also the recipe as listed says that it serves 8 by making 24 mushrooms. Increase this number, these are so good most of your guests will want to eat more than 3 each.


This recipe is TO DIE FOR. I just made these mushrooms for a New Year's Eve party and they were a smashing success. I got two recipe requests for it, the ultimate compliment. And the recipe is easy to boot! Thanks for sharing.


I really liked this recipe but there are two changes I would make the next time. They seemed to take a longer time to cook in the oven so I finished them in the broiler. Next time I will use the broiler at less time than the recipe calls for in the oven. It also needed mozzerella cheese added to the top before broiling. The filling was incredible!
