Step‑by‑Step Instructions for Scottish Rumbledethumps
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) while you prepare your ingredients. Grease a 9×9 inch baking dish generously with butter to ensure easy serving later. As the oven warms up, gather your boiled and mashed potatoes and turnips, which will form the creamy base of your Scottish Rumbledethumps.
Step 2: Sauté the Cabbage
In a large skillet over medium heat, melt 2 oz of unsalted butter. Add the thinly sliced cabbage and sauté for about 5 minutes, stirring occasionally, until it softens and becomes fragrant. This step will infuse the cabbage with buttery goodness, ensuring your Scottish Rumbledethumps has a delightful texture and flavor.
Step 3: Combine Ingredients
In a large mixing bowl, combine the mashed potatoes, mashed turnips, and the sautéed cabbage mixture. Add the remaining 1 oz of butter, kosher salt, and black pepper. Mix thoroughly until well blended, creating a creamy and flavorful filling that captures the essence of traditional Scottish Rumbledethumps.
Step 4: Spread in Baking Dish
Transfer the hearty mixture into the greased baking dish, spreading it evenly to ensure uniform cooking. Smooth the top with a spatula, creating a nice surface for the cheese. This layer will offer the perfect foundation for that golden, bubbling topping you are about to create.
Step 5: Add Cheese Topping
Sprinkle the grated sharp cheddar cheese evenly across the surface of the casserole. This delicious topping will melt beautifully and add an irresistible savory layer to your Scottish Rumbledethumps. Make sure to cover the entire surface for uniform melting and browning.
Step 6: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes, allowing the flavors to meld. After 30 minutes, carefully remove the foil and bake for an additional 5 minutes until the cheese is lightly browned and bubbling, a visual cue that your dish is nearing perfection.
Step 7: Cool Before Serving
Once baked, remove the Scottish Rumbledethumps from the oven and let it sit for 5 minutes. This brief resting time allows the casserole to firm up slightly, making it easier to serve. The moment is almost here—get ready to enjoy this comforting Scottish dish that’s bursting with flavor and nostalgia!
