Step‑by‑Step Instructions for Scottish Rumbledethumps

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take a 9×9 inch baking dish and grease it generously with unsalted butter to ensure your Scottish Rumbledethumps won’t stick. This preparation makes it easy to serve the delicious casserole later.

Step 2: Sauté the Cabbage
In a skillet over medium heat, melt 2 ounces of butter. Add the sliced green cabbage to the pan, sautéing it for about 5 minutes until it softens slightly and turns a vibrant green. Stir occasionally to prevent sticking, ensuring even cooking and enhancing the flavors of the cabbage.

Step 3: Combine the Mashed Ingredients
In a large mixing bowl, combine the boiled and mashed russet potatoes, boiled and mashed turnips, and the sautéed cabbage. Add the remaining 1 ounce of butter, kosher salt, and black pepper, mixing everything until fully incorporated. The mixture should be creamy and well-seasoned, creating the hearty base for your Scottish Rumbledethumps.

Step 4: Transfer to the Baking Dish
Carefully spread the mashed mixture evenly into the prepared baking dish, ensuring it fills the corners for consistent baking. Once smoothed out, sprinkle a generous layer of grated sharp cheddar cheese on top, creating a delightful cheesy crust that will melt beautifully during baking.

Step 5: Bake the Casserole
Cover the baking dish with foil and place it in the preheated oven. Bake for 30 minutes; this allows the flavors to meld wonderfully. After this time, remove the foil and bake for an additional 5 minutes or until the top is lightly browned and bubbling, giving your Scottish Rumbledethumps a lovely golden finish.

Step 6: Rest and Serve
Once baked, remove the casserole from the oven and let it sit for about 5 minutes to set. This short cooling period enhances the textures and makes serving easier. Your Scottish Rumbledethumps are now ready to enjoy, perfect for a warm, comforting meal straight from the oven!
