• 1 medium onion, finely chopped
• Salt and pepper, to taste
• 1 cup (100g / 0.22 lb) grated Scottish cheddar or sharp cheddar cheese

Directions

Step 1: Cook the Potatoes

1. Boil the Potatoes:
   Place the diced potatoes in a large pot and cover with water. Add a pinch of salt and bring to a boil. Reduce the heat and simmer for 15-20 minutes, or until the potatoes are tender.
2. Drain and Mash:
   Drain the potatoes and return them to the pot. Add 2 tablespoons of butter and mash until smooth. Set aside.

Step 2: Sauté the Cabbage and Onion

1. Cook the Vegetables:
   In a large skillet, melt the remaining 1 tablespoon of butter over medium heat. Add the chopped onion and cook for 3-4 minutes, until softened.
2. Add the Cabbage:
   Add the shredded cabbage and cook for another 5-7 minutes, stirring occasionally, until the cabbage is tender but still has a slight bite.
3. Season:
   Season the cabbage and onion mixture with salt and pepper to taste.

Step 3: Combine and Assemble

1. Mix Everything Together:
   Add the sautéed cabbage and onion mixture to the mashed potatoes, stirring until everything is well combined.
2. Transfer to Baking Dish:
   Spoon the mixture into a greased baking dish (about 9×9 inches or similar size).
3. Top with Cheese:
   Sprinkle the grated cheese evenly over the top.

Step 4: Bake

1. Bake:
   Preheat your oven to 375°F (190°C). Bake the Rumbledethumps for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown.
2. Serve Warm:
   Allow the Rumbledethumps to cool slightly, then serve warm as a side dish or main.

Notes

• Customize the Cheese: Scottish cheddar adds a traditional flavor, but you can use any sharp or melty cheese you prefer.
• Add Bacon or Ham: For a heartier version, add cooked bacon or ham to the mixture before baking.
• Leftover-Friendly: Rumbledethumps is a great way to use up leftover mashed potatoes or cabbage.
• Storage Tips: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave.
