One of the most popular comfort foods in the United Kingdom is called shepherd's pie, a hot and savory dish reminiscent of a casserole, consisting of minced lamb or mutton meat, potatoes, onions, carrots, Worcestershire sauce, thick gravy, and seasonings such as marjoram, parsley, and black pepper.

All of the ingredients are placed under a roof of buttery, creamy mashed potatoes, and baked in an oven until the pie is ready for consumption. This simple delicacy was invented by shepherds in the 18th century England and Scotland. The pie became extremely popular in the 1870s, and not by coincidence, as mincing machines became widely available to the public in those years.

Today, shepherd's pie is a great way of using up leftover cooked meat, but it is generally recommended to use fresh meat for a better flavor and texture of the pie. This hearty pie is a favorite in numerous pubs, homes, and restaurants throughout the United Kingdom.
