What is "Lancashire hotpot"?

Lancashire hotpot is a hearty traditional English dish that originated in the Lancashire region of northern England. It is a meat and vegetable casserole made with lamb, onions, carrots, and potatoes, all layered in a large pot and cooked slowly until the meat is tender and the vegetables are soft and flavorful. The dish is traditionally cooked in a ceramic pot with a lid, which is then placed in the oven for several hours. The slow cooking process allows the flavors to meld together and the juices from the meat to infuse the vegetables. The top layer of potatoes is sliced thin and arranged in a decorative pattern, then brushed with butter to create a crispy crust.
