Step‑by‑Step Instructions for Scottish Rumbledethumps
Step 1: Preheat and Prepare the Dish
Begin by preheating your oven to 350°F (175°C) while you prepare your baking dish. Grease a 9×9 inch baking dish generously with butter to prevent sticking, ensuring it’s fully coated for that perfect golden outcome. This is where your hearty Scottish Rumbledethumps will come together, so make sure it’s ready for the delicious filling!
Step 2: Sauté the Cabbage
In a skillet over medium heat, melt 2 ounces of butter until it’s bubbly and fragrant. Add the thinly sliced green cabbage to the pan, stirring frequently for about 5 minutes, or until the cabbage is tender and slightly wilted. This step adds a lovely texture and flavor to your Scottish Rumbledethumps, setting a savory base for the casserole.
Step 3: Combine the Ingredients
In a large mixing bowl, combine the boiled and mashed russet potatoes, mashed turnips, sautéed cabbage, the remaining butter, kosher salt, and freshly cracked black pepper. Mix these ingredients well until they are fully incorporated and the mixture is creamy and smooth. The warmth of the mashed vegetables will help meld the flavors beautifully, creating the perfect filling for your casserole.
Step 4: Assemble the Casserole
Transfer the potato and turnip mixture into your prepared baking dish, spreading it out evenly with a spatula. Take your time to ensure an even layer, as this will help it bake uniformly. Next, generously sprinkle the grated sharp cheddar cheese over the top, creating a deliciously melty layer that will brown 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, allowing the flavors of the Scottish Rumbledethumps to blend and the dish to heat through. After 30 minutes, carefully remove the foil and bake for an additional 5 minutes, or until the cheese is golden brown and bubbling, creating an enticing aroma throughout your kitchen.
Step 6: Rest and Serve
Once baked, remove the casserole from the oven and let it sit for about 5 minutes before serving. This resting time allows the casserole to set, making it easier to slice. As you dish it out, you’ll find a creamy filling topped with a perfectly crisp layer of cheese, ready to warm your heart and feed your soul!

Make Ahead Options
These Scottish Rumbledethumps are a fantastic option for meal prep! You can prepare the entire casserole up to 24 hours in advance by assembling it in your baking dish, covering it with foil, and refrigerating. This allows the flavors to meld beautifully. To maintain quality, ensure you let it cool to room temperature before wrapping it tightly. When you’re ready to enjoy, simply bake it directly from the fridge, adding an extra 10-15 minutes to your cooking time to ensure it is heated through. This way, you can have a comforting, hearty meal ready with minimal effort, perfect for those busy weeknights!

Scottish Rumbledethumps Recipe FAQs
How do I select the best vegetables for my casserole?
Absolutely! When choosing turnips, look for ones that are firm and heavy for their size without dark spots or soft spots, which indicate overripeness. For cabbage, opt for heads that are tightly wrapped and feel heavy; avoid any that have wilting leaves or discoloration. The fresher the produce, the better your Scottish Rumbledethumps will taste!
What’s the best way to store leftovers?
Very simple! Store any uneaten casserole in an airtight container in the refrigerator, and it will last for about 3 to 4 days. If you want to keep it longer, make sure it cools completely before sealing it up to avoid steam buildup, which can lead to sogginess.
Can I freeze Scottish Rumbledethumps?
Absolutely! You can freeze your casserole for up to 3 months. Just make sure to wrap the dish tightly in plastic wrap followed by aluminum foil to keep it safe from freezer burn. When you’re ready to enjoy it again, thaw it in the fridge overnight before reheating.
What if my casserole appears watery after baking?
The more the merrier! A watery casserole can be the result of too much moisture in the vegetables. To troubleshoot, ensure your cabbage is well-dried after washing, and if you’re using leftover veggies, drain any excess liquids before mixing them in. If you find yourself with a watery casserole post-bake, pop it back in the oven uncovered for a few minutes to help evaporate some of the moisture.
Is this recipe suitable for those with dietary restrictions?
Yes! If you have someone with dairy allergies, you can easily substitute the unsalted butter with olive oil or a dairy-free butter alternative, and the cheese can be swapped for a vegan cheese option. Always ensure to double-check the specific dietary needs of your guests, but with a few simple adjustments, everyone can enjoy this comforting classic!
