Stuffed Portabella Mushrooms - cooking recipe

Ingredients

25 -30 small portabella mushrooms or 6 large portabella mushrooms
3 ounces olive oil
8 ounces onions, diced
8 ounces white mushrooms, washed and sliced thin
4 -8 ounces marsala wine
4 ounces breadcrumbs
4 ounces heavy cream
1/4 ounce ground nutmeg
salt, to taste
white pepper, to taste
3 ounces chopped fresh parsley
8 ounces gruyere cheese, grated
4 ounces parmesan cheese, grated

Preparation

Heat oil in a saute pan, add onions and cook until translucent.
While the onions are cooking, chop mushroom stems and slice caps.
Add chopped mushroom stems and caps and saute until tender, or about 10 minutes. Use the wine to deglaze the pan and simmer for 3 minutes to burn off the alcohol.
In a small bowl, combine the bread crumbs, cream, seasonings, and parsley. Add to pan with cream.
Simmer until thick. Cool.
Preheat the oven to 400\u00b0F.
Once cool, spoon onto Portobello mushroom caps and add cheeses on each cap. Bake in oven until mushrooms are tender and cheese is lightly browned, about 20 minutes.
Slice each cap into four pieces and serve.
