Step‑by‑Step Instructions for Scottish Rumbledethumps
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). While the oven warms up, grease a 9×9-inch baking dish with unsalted butter to prevent sticking. This is important as it allows the Scottish Rumbledethumps to bake evenly and slide out easily when ready to serve.
Step 2: Sauté the Cabbage
In a skillet over medium heat, melt 2 ounces of unsalted butter. Once melted, add the sliced green cabbage and sauté for about 5 minutes until it’s slightly softened. You want the cabbage to maintain a bit of crunch while infusing it with that wonderful buttery flavor, setting the stage for the cozy casserole.
Step 3: Combine the Vegetables
In a large mixing bowl, combine the boiled and mashed russet potatoes, mashed turnips, sautéed cabbage, the remaining butter, kosher salt, and black pepper. Mash everything together thoroughly until you achieve a rich, smooth texture. This harmonious blend brings the rustic flavors of the Scottish Rumbledethumps to life.
Step 4: Transfer the Mixture
Carefully transfer the combined mixture into your prepared baking dish, spreading it evenly with the back of a spatula. This step ensures each bite of your Scottish Rumbledethumps is packed with flavorful goodness. Smooth out the top for an even golden crust as it bakes; a well-distributed mixture leads to a comforting texture.
Step 5: Add the Cheese Topping
Generously sprinkle the grated sharp cheddar cheese over the top of the potato mixture. The cheese layer adds a rich, savory element to the Scottish Rumbledethumps and will melt beautifully, creating a luscious, golden-brown crust that you won’t be able to resist.
Step 6: Bake to Perfection
Place your baking dish in the preheated oven and cover it with foil. Bake for 30 minutes, then uncover the dish and allow it to bake for an additional 5 minutes. This uncovered baking time allows the cheese to bubble and the top to turn a delicious golden brown—perfect for that cozy comfort food vibe.
Step 7: Rest Before Serving
Once baked, remove the Scottish Rumbledethumps from the oven and let it sit for 5 minutes. Allowing it to rest helps the casserole set slightly, making it easier to serve. The internal flavors will continue to mingle, giving you a delightful dish full of warmth in every bite.
