Preheat the oven to 375°F, and spray a large baking pan with nonstick spray. Set aside.
Add the Italian sausage and onion to a large skillet over medium heat, and cook until no pink remains, about 8 minutes.
16 ounces ground Italian sausage, ½ white onion
Add the diced mushroom stems, garlic, salt, oregano, parsley and pepper, and cook for about 5 minutes or until the mushrooms have reduced significantly.
Stir in the cream cheese until fully melted, then add ¾ of the mozzarella and ¾ of the parmesan cheese to the pan. Cook until the cheese is fully melted.
4 ounces block-style cream cheese
Remove the pan from the heat, and let the mixture cool for about 5 minutes before stirring in the egg.
1 large egg
Place the mushrooms on the prepared baking pan, and fill each one with about a tablespoon of filling or until heaping.
Sprinkle on the remaining mozzarella and parmesan cheese then bake for 20 to 25 minutes or until the top of the cheese starts to bubble and the mushrooms turn a dark brown color.
Serve with freshly chopped parsley for garnish if desired. See post for storage options.
