The primary ingredient in shepherd's pie is minced meat, traditionally lamb, although variations may use beef. This hearty dish typically features a bottom layer of seasoned meat mixed with vegetables such as peas and carrots, often combined with gravy or broth for added richness. The top layer consists of creamy mashed potatoes, which are spread over the meat mixture and baked until golden brown. Shepherd's pie is a comforting dish that originated in the UK and is known for its robust flavors and satisfying texture, making it a popular choice for family meals.
