Salt, pepper and paprika chicken pieces. Brown them in 4 tablespoons butter. Lay in large casserole. Saute mushrooms in remaining butter for 5 minutes. Add flour, broth and sherry, stirring constantly. Cook 5 minutes. Arrange artichoke hearts between chicken pieces. Pour sauce over and bake, covered, for 40 minutes or longer in a 375° oven.
I add a slice of white cheese to each chicken piece and some sliced avacadoes the last 10 minutes of baking. Even yummier.
