Historic County Durham and Sunderland slow-cooked working-class hotpot: layered corned beef, thinly sliced potatoes, sweet onions, and carrots baked in rich savory stock.
Grease a deep casserole dish with butter. Layer potatoes, onions, carrots, and sliced corned beef, seasoning layers with pepper and salt.
Finish with a neat overlapping layer of potato slices on top. Pour hot beef stock over until vegetables are almost submerged.
Dot top potatoes with butter. Cover with foil and bake at 180°C for 50 minutes until vegetables are tender.
Remove foil and bake for an additional 25 minutes until top potatoes are crisp, golden, and browned at the edges. Serve hot with crusty bread.
