Ingredients
Method
- Position an oven rack in the center and preheat to 350°F (177°C). Clean the mushrooms by gently wiping them with a paper towel. Detach the stems, finely chop them, and set aside. Keep the mushroom caps separate.
- Warm the olive oil in a large nonstick skillet over medium heat. Add the sausage and cook, breaking it into small crumbles, until fully browned, approximately 8 minutes. For a finer texture, a potato masher may be used.
- Incorporate the chopped mushroom stems, vinegar, salt, and black pepper into the skillet. Sauté until the stems soften, about 4 minutes.
- Stir in the green onions, garlic, and breadcrumbs. Remove from heat and allow the mixture to cool slightly.
- In a large mixing bowl, blend the softened cream cheese, egg yolk, and Parmesan cheese until smooth. Gently fold in the cooled sausage mixture until evenly combined.
- Generously spoon the prepared filling into each mushroom cap, forming a slight mound on top. Arrange the stuffed mushrooms in a baking dish so they fit snugly together in a single layer.
- Bake for approximately 20 minutes, or until the tops are golden brown and the filling is heated through. If any liquid is released during baking, leave it behind in the dish.
- Transfer to a serving platter and allow the mushrooms to cool for at least 5 minutes before serving. Garnish with freshly chopped parsley and enjoy warm or at room temperature.
