I used more sausage and bacon, and subbed duck for the lamb, by then, this recipe made enough for 12 servings. Granted we are not big eaters, but their serving size of 1 1/2 cups is very large for something this rich, and filling. Don't bother with the crumb topping, it just gets soggy, not brown and crunchy. And I cooked this 4 hours, and it really needed longer, the beans still weren't done to our liking.
We love this recipe, but made a few changes: we add a whole bag of beans, more turkey kielbasa and lamb, 1 tsp rosemary, all broth - no water and probably double the amount of brandy! The rosemary is the best addition! Also, when we add the cheese/bread crumbs, we broil it, it really does not need to cook longer.
