Shepherd's pie is a hearty and comforting British dish made with minced lamb or beef, mixed with vegetables such as carrots, peas, and onions, and topped with a layer of mashed potatoes. The meat and vegetables are cooked together in a rich gravy, which adds flavor and moisture to the dish. The mashed potatoes are then spread over the top and baked until golden and crispy. Shepherd's pie is a great option for a quick and satisfying meal, especially during colder months.
