Shepherd's pie is a hearty and comforting British dish 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 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 popular dish during the colder months and is often served with a side of vegetables or a salad.
