What Is Rumbledethumps?
Rumbledethumps is a classic Scottish dish that blends mashed potatoes, cooked cabbage or kale, and sautéed onions, all baked together until hot and golden. The dish hails from the Scottish Borders and Lothian regions and has been enjoyed for centuries as a thrifty way to use up leftover vegetables — especially after big meals like Sunday roasts or holiday dinners.
Though the name might sound whimsical, it reflects a rustic way of cooking that was practical, filling, and perfect for feeding families on a budget. It’s part of a broader tradition of British Isles dishes like England’s Bubble and Squeak and Ireland’s Colcannon — each region’s own take on comforting mashed potatoes mixed with greens.
Full recipe:
Ingredients:
-
500g (about 1 lb) potatoes, peeled and chopped
-
250g (about ½ lb) green cabbage or kale, finely shredded
-
1 medium onion, finely chopped
-
2 tbsp butter
-
Salt and pepper, to taste
-
Optional: 100g (3.5 oz) grated mature cheddar cheese for topping
Instructions:
-
Boil the potatoes in salted water until tender (about 15–20 minutes). Drain and mash with a little butter or milk until smooth.
-
While the potatoes are cooking, sauté the chopped onion in butter over medium heat until soft and translucent (about 5 minutes).
-
Blanch or lightly steam the cabbage or kale for 3–4 minutes until just tender, then drain well.
-
Combine the mashed potatoes, sautéed onions, and cabbage in a bowl. Season generously with salt and pepper. Mix until fully combined.
-
Transfer the mixture to a buttered ovenproof dish. If using cheese, sprinkle it generously over the top.
-
Bake at 180°C (350°F) for 20–25 minutes, or until the top is golden and slightly crispy.
-
Serve hot as a main or side dish.
