Shepherd’s pie, also known as cottage pie, is a popular comfort food dish that originated in the United Kingdom. Traditionally, it was made with leftover roasted or stewed lamb, hence the name “shepherd’s pie.” However, over time, it has become more common to use ground beef or other meats, resulting in a dish known as beef casserole. Beef casserole follows a similar concept to the traditional shepherd’s pie but is made primarily with ground beef instead of lamb. The dish typically consists of a savory meat filling with vegetables, layer of mashed potatoes and shredded cheese baked until golden and bubbly. YOU MY ALSO LIKE: This is mine twist on…
