This Pub-Style Guinness Beef Pie recipe is about as comforting and fulfilling as any recipe ever was. The Guinness and porcini add such a depth of flavor and the slow simmered beef becomes fork-tender. And of course, the crust. You simply must make this with the crust. It all comes together to make Irish magic! You will need 10 oz. ramekins, or you can make in a pie dish.
