Step‑by‑Step Instructions for Scottish Rumbledethumps
Step 1: Preheat and Prepare the Baking Dish
Begin by preheating your oven to 350°F (175°C). While the oven warms, grab a 9×9 inch baking dish and generously grease it with 1 ounce of unsalted butter. This will prevent the casserole from sticking and will help achieve that delicious golden crust when you bake the Scottish Rumbledethumps.
Step 2: Sauté the Cabbage
In a large skillet over medium heat, melt 2 ounces of butter. Once melted, add the thinly sliced cabbage and sauté for about 5 minutes, stirring frequently until it’s slightly softened but still bright green. This step adds a lovely flavor and fresh crunch to the Rumbledethumps, setting the stage for a delightful texture.
Step 3: Combine Ingredients
In a large mixing bowl, combine the boiled and mashed russet potatoes and turnips. Add the sautéed cabbage, the remaining 1 ounce of butter, and sprinkle in the kosher salt and black pepper. Stir everything together until the mixture is well combined and creamy. This hearty blend will be the flavorful base of your Scottish Rumbledethumps.
Step 4: Transfer to Baking Dish
Once the mixture is blended to your liking, transfer it into the greased baking dish, spreading it evenly with a spatula. Ensure the surface is nice and smooth to promote even cooking. Next, generously top your mixture with 1 ounce of grated sharp cheddar cheese, which will create a rich, cheesy crust as it bakes.
Step 5: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes to let the flavors meld together beautifully. After the first 30 minutes, carefully remove the foil to allow the cheese to brown and bubble; continue baking uncovered for an additional 5 minutes. The top should be lightly browned and inviting.
Step 6: Cool and Serve
After a delicious aroma fills your kitchen, remove the Rumbledethumps from the oven and let it sit for about 5 minutes. This resting period helps firm up the casserole slightly, making it easier to slice and serve. When ready, dish out generous portions of your comforting Scottish Rumbledethumps and enjoy!
