Step‑by‑Step Instructions for Scottish Rumbledethumps
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, generously grease a 9×9 inch baking dish with about 1 oz of unsalted butter. This will help the rumbledethumps develop a beautifully golden crust without sticking to the dish.
Step 2: Sauté the Cabbage
In a skillet set over medium heat, melt 2 oz of butter. Once melted, add the thinly sliced green cabbage and sauté for approximately 5 minutes. Stir occasionally until the cabbage softens and turns a vibrant green, providing a lovely crunch in your Scottish rumbledethumps.
Step 3: Combine the Mash
In a large mixing bowl, combine your boiled and mashed russet potatoes and mashed turnips. Add the sautéed cabbage, remaining 1 oz of butter, kosher salt, and black pepper to the mix. Mash everything well until fully combined and smooth, ensuring the flavors meld seamlessly for a comforting casserole.
Step 4: Transfer to Baking Dish
Spread the potato and turnip mixture evenly into the prepared baking dish. Be sure to press it down slightly to eliminate air pockets — this helps create a hearty texture in the Scottish rumbledethumps.
Step 5: Add Cheese and Bake
Sprinkle the grated sharp cheddar cheese generously over the top of the casserole. Cover the dish with aluminum foil and place it in the preheated oven to bake for 30 minutes. This will allow the flavors to blend beautifully before getting that irresistible cheesy crust.
Step 6: Final Bake and Serve
After 30 minutes, carefully remove the foil and continue baking for an additional 5 minutes. Keep an eye on it for the last few minutes until the top becomes lightly browned and bubbly. Let the rumbledethumps sit for about 5 minutes before serving to enhance the flavors and texture.

Scottish Rumbledethumps Recipe FAQs
How do I choose the right turnips for my rumbledethumps?
Absolutely! When selecting turnips, look for firm ones with smooth skin and without dark spots. They should feel heavy for their size; about 2 medium turnips should work perfectly. Avoid any turnips that are soft or have blemishes, as these can affect the flavor and texture of your casserole.

Don’t worry, I’ve been there too! If your casserole turns out too watery, it could be due to extra moisture in the vegetables.

On the flip side, if it’s too dry, try incorporating a splash of milk or cream to bring back some moisture.
