Creamy Chicken with Prosciutto & Mushrooms

INGREDIENTS:
2 tablespoons butter or margarine, melted
6 chicken thighs
salt and pepper to taste
6 slices prosciutto (thin sliced)
2 tablespoons minced garlic, divided
1 cup sliced fresh mushrooms
1/4 cup dry white wine (optional)
1 cup sour cream

DIRECTIONS:
Preheat oven to 350 degrees. Drizzle butter into a casserole dish. Season chicken with salt, pepper, and 1 tablespoon garlic. Wrap chicken thighs in prosciutto, and place in casserole dish. Sprinkle mushrooms and remaining garlic on top of chicken.
Bake in a preheated oven until juices run clear, about 1 hour. Remove chicken to a platter, and cover with aluminum foil to keep warm.
Pour drippings from casserole into a skillet set over medium-low heat. Whisk in wine and sour cream, and cook until warmed through, about 5 to 7 minutes. Pour over chicken, and serve.
