Shepherd's pie is a comforting and hearty dish that consists of minced lamb or beef, topped with mashed potatoes and baked until golden and crispy. The secret to a delicious shepherd's pie lies in the flavorful meat filling, which should be seasoned with herbs and spices to enhance the taste. The mashed potatoes should be creamy and smooth, providing the perfect contrast to the savory meat filling. Shepherd's pie is a classic British comfort food that is perfect for a cozy dinner on a cold evening.
