The main ingredient in a shepherd's pie is minced meat, typically lamb. This traditional dish hails from the UK and is designed to be comforting and hearty. The minced lamb is usually cooked with onions, carrots, and peas, and is then topped with a layer of creamy mashed potatoes before being baked until golden. Variations can occur, where beef might be used instead, and additional herbs and spices can be added for flavor. Shepherd's pie is cherished for its rich flavors and satisfying textures, making it a beloved meal in many households.
