Lancashire hotpot recipe: Northcote's slow lamb and potato
Nigel Haworth built his name on this dish at Northcote: lamb braised low under a shingled roof of potato until the top turns dark gold and the meat falls apart.
Lancashire hotpot is lamb and onion, cooked low under a tiled layer of sliced potato until the meat gives way on the fork and the top turns deep gold. Nigel Haworth, who ran the kitchen at Northcote for over three decades, made the dish his signature there.
The hotpot's origins reach back further than the county name: a mutton-and-onion stew baked slowly in a tall, straight-sided pot was cheap, needed almost no attention, and could be left in a low oven all day, which is why it fed Lancashire's cotton-mill and mining families through the 19th century. The version below follows Haworth's proportions and timings, built for a home oven rather than a restaurant kitchen.
Ingredients
A dish built to be forgotten about for two and a half hours is still the best argument against fussing over lamb.
- 1 kg lamb neck and shoulder, trimmed and cut into 3–4cm chunks
- 700 g onions, thinly sliced
- 1 kg King Edward potatoes, peeled
- 25 g plain flour
- 40 g salted butter, melted
- 150 ml lamb or chicken stock
- Sea salt and white pepper
Method
- Season the lamb with a teaspoon of salt and a good pinch of pepper, then toss it in the flour. The flour thickens the juices as the meat braises, so the finished dish stays moist rather than swimming in liquid. Lay the lamb in the base of a deep, straight-sided ovenproof dish.
- Sweat the onions in half the butter with a pinch of salt for 4–5 minutes, until soft but not coloured, and spread them evenly over the lamb. Cooking them gently first takes the rawness out of the onion and sweetens the base of the dish before it goes into the oven.
- Slice the potatoes about 2mm thick, toss them in the remaining butter with salt and a little pepper, and shingle them over the onions in overlapping layers. Pour the stock in around the edge, not over the top, so the potato stays dry enough to crisp later.
- Cover and bake at 200°C (400°F, gas 6) for 30 minutes, then turn the oven down to 130°C (250°F, gas ½) and cook for a further 2½ hours. The long, low stage is what turns tough neck and shoulder tender without drying out the potato underneath.
- Uncover the dish and return it to a 200°C oven for 30–40 minutes, until the potatoes are deep gold and crisp at the edges. The uncovered blast at the end is what gives hotpot its characteristic top; skip it and the dish stays pale and soft all over.
Serve it the Lancashire way
Hotpot is traditionally served with pickled red cabbage, whose sharpness cuts through the richness of the lamb and butter. A simple green vegetable on the side is enough; the dish itself carries the meal.
It is also, by design, a dish that improves from being left alone: Haworth has noted that Northcote's current head chef, Mat Sherry, trained under the same kitchen's long-running style before taking it elsewhere and, this month, bringing it back.
Can hotpot be made ahead? Yes: it reheats well, and many cooks think it tastes better the next day, once the flavours have settled.
