All the other Leprechauns will turn green with envy when they taste this twice-as-Irish Shepherd’s Pie. An oozing layer of melted cheese just beneath the topping makes it doubly as delicious!
This deeply flavorful dish is as much a comfort food as it is a luscious meal to serve to guests. The stew may be made a day or two in advance and reheated, and it freezes well. The polenta is best made just before serving.
