Rumbledethumps is a Scottish dish made of boiled potatoes, cabbage and onions. These ingredients are cooked and then mashed together with spices. The mixture is put into a baking dish and covered with cheddar or another sharp cheese. It is then baked until the cheese on the top of the casserole is bubbling and browned. Rumbledethumps can be made ahead of time and reheated before serving.
This dish is usually served alongside a main course of meat, though it is hearty enough to be eaten as a meal on its own. Traditionally, it was made of leftover potatoes, vegetables and, sometimes, meats. When it is made from scratch, some recipes call for the vegetables to be sautéed in butter, onions and herbs before they are mixed with the potatoes. Any vegetable can be used in this dish, though cabbage and kale are the most common. Rumbledethumps is an onomatopoeic name that describes the sounds made when the vegetables are mashed.
