  • 4 ounces cream cheese softened
  • cup freshly grated parmesan cheese grated

  • Melt the butter in a medium skillet over medium heat. Add the chopped mushroom stems and cook for 5 minutes, or until most of the moisture is gone. Add the onion, garlic, salt, and pepper, and cook for another 1 to 2 minutes, until the onion has softened. Transfer the mushroom mixture to a mixing bowl, and let it cool slightly.

Notes

Mushrooms naturally get a little wet and soggy when cooking. If you'd like to avoid extra liquid as much as possible you can...
  • Chill the mushroom filling before stuffing. 
  • Place the mushrooms on a wire rack on top of the baking sheet. That way any of the mushroom juices will drain away from the mushrooms.
