England has bubble and squeak, Ireland owns colcannon and, in Scotland, this delicious fry-up of vegetables is called rumbledethumps. The dish is popular in the Scottish border regions and is perfect for using up leftover mashed potatoes and vegetables you have in the fridge.

This rumbledethumps recipe calls for swede (also known as turnip or neeps) and cabbage or kale. The vegetable mixture is topped with cheese and then baked until bubbling. The beauty of the dish is it can be made the day before and heated up. All it needs alongside it is a hearty stew, or, if you prefer to eat it on its own, try​ it with a fried egg on top.


  • 21 ounces potatoes, peeled, boiled, and mashed, or leftovers

  • 14 ounces swede or turnip, peeled, boiled, and mashed, or leftovers

  • 3 ounces unsalted butter, softened, divided

  • 9 ounces savoy cabbage or kale, finely sliced

  • Kosher salt, to taste

  • Pepper, to taste

  • 1 ounce grated cheddar cheese

  4. Add the cooked cabbage or kale to the bowl of potato and swede along with the remaining butter and mash together thoroughly. Season with salt and pepper to taste. Potato can soak up salt, so be generous with it to add a good flavor.
