Shepherd's pie is a classic British dish that is made with minced lamb or beef, topped with mashed potatoes, and baked until golden and crispy. The meat is cooked with onions, carrots, and peas in a rich gravy, and then it is topped with a layer of creamy mashed potatoes. The pie is then baked in the oven until the top is golden and the filling is bubbling. Shepherd's pie is a comforting and hearty dish that is perfect for cold winter nights. It is a favorite in British households and is often served with vegetables or a side salad.
