To finish: Melt the butter in a large enameled cast-iron casserole. Add the onion and cook over medium heat until tender, about 5 minutes. Stir in the paprika and cayenne. Cook 1 minute, stirring. Add the mushroom and cook 8 to 10 minutes or until browned.
Stir in the remaining 3 tablespoons of flour and cook over low for 2 minutes, stirring. Heat the stock and stir in, stirring until the sauce is smooth.
Stir in the crème fraiche and beans. Cook until beans are hot 8 to 10 minutes longer.
