Classic Lancashire Hotpot
Slow-braised lamb and onions topped with overlapping sliced potatoes, cooked until the meat is meltingly tender and the potato crust is golden and crisp. Proper northern comfort food — unfussy, hearty and glorious on a chilly evening.
Lancashire hotpot is the sort of dish your grandparents made on a blustery evening — unfussy, slow-cooked and brilliantly satisfying. Layers of braised lamb and sweet onions are hidden under a crown of buttery, overlapping potato slices that roast into a golden, crinkly lid.
Make this when you want comfort with a little ceremony: it doesn’t need constant attention, but it rewards patience. Perfect for family dinners, batch-cooking for the week, or proving that good things happen when you give the oven time to work its magic.
Ingredients
- 1.2 kg lamb shoulder, trimmed and cut into 3cm pieces
- sea salt — to taste
- black pepper — freshly ground, to taste
- 30 ml plain olive oil
- 50 g unsalted butter
- 3 pieces large onions, thinly sliced — about 450 g total
- 2 pieces carrots, thickly sliced — about 150 g
- 15 ml tomato purée
- 15 ml Worcestershire sauce
- 10 ml dried thyme or 4 sprigs fresh, leaves removed — if using fresh, use 1 tbsp
- 2 leaves bay leaves
- 600 ml lamb or beef stock — hot
- 15 ml flour (optional, to thicken) — optional — see notes
- 1.2 kg Maris Piper or Yukon Gold potatoes, peeled — about 6 medium potatoes
- 25 g butter, for dotting the potato top — cut into small knobs
- 30 ml fresh parsley, chopped — to garnish (optional)
Equipment
- 23–26 cm ovenproof casserole / Dutch oven
- large frying pan
- mandoline or sharp knife
- peeler
Instructions
Preheat the oven to 170°C fan / 190°C conventional / 375°F. Pat the lamb dry with kitchen paper, season generously with salt and freshly ground black pepper.
Heat the olive oil in a large frying pan over medium–high heat. In batches (don’t overcrowd the pan), brown the lamb pieces on all sides until well caramelised, 3–4 minutes per batch. Transfer browned pieces to a plate.
Reduce heat to medium, add 25 g of the butter to the pan and, once foaming, add the sliced onions and carrots. Cook, stirring occasionally, until the onions are soft and starting to caramelise, about 8–10 minutes.
Push the veg to the side, add the tomato purée and Worcestershire sauce; cook for 30 seconds. If you want a slightly thicker gravy, sprinkle the optional tablespoon of flour over the onions now and cook for 1 minute.
Return the browned lamb to the pan, add the thyme and bay leaves, pour in the hot stock and bring to a gentle simmer for 5 minutes to combine flavours and seal the meat.
Transfer everything (meat and braising liquid) to a 23–26 cm ovenproof casserole or Dutch oven. Taste the liquid and adjust seasoning — it should be slightly under-salted because the potatoes will dilute flavours.
Thinly slice the peeled potatoes (3 mm / about 1/8 inch) with a sharp knife or mandoline. Arrange the slices in overlapping concentric circles over the casserole, sealing the edges down the sides so the potatoes cover the meat completely. Dot the remaining 25 g butter over the potato surface and season with a little salt and pepper.
Cover the casserole with its lid (or tightly with foil) and bake in the preheated oven for 90 minutes.
Remove the lid/foil and increase the oven temperature to 200°C fan / 220°C conventional / 425°F. Bake uncovered for a further 20–30 minutes until the potato top is golden and the edges are crisp. If the top browns too quickly, reduce the oven by 10–20°C and give a little more time.
Remove from the oven and rest for 10 minutes. Scatter chopped parsley over the top to brighten and serve straight from the casserole.
Tips
- Use a mandoline or very sharp knife to slice potatoes thinly and uniformly — uneven slices make patchy cooking.
- Browning the lamb in batches builds rich flavour; don’t rush or overcrowd the pan or you’ll steam the meat.
- Assemble the dish a few hours ahead and refrigerate (covered). Bring back to room temperature for 30 minutes before baking and add 10–15 minutes to the oven time.
- If the braise seems thin before you add the potatoes, reduce it on the hob for a few minutes — you want a glossy, not watery, sauce.
- Leftovers reheat beautifully: rewarm gently in a 160°C oven for 20–30 minutes covered, then uncover for 10 minutes to re-crisp the top.

FAQ
Can I make this in a slow cooker?
Yes — brown the lamb and soften the onions on the hob, transfer to the slow cooker with stock and herbs, then cook on low for 6–8 hours. Arrange the potato topping in the final hour and finish under the grill to crisp.
Do I have to use butter on the potato top?
Butter gives a richer, golden finish, but you can use lard, dripping or a drizzle of olive oil. The texture and flavour will shift slightly.
How can I get a really crisp potato top?
Slice thinly and overlap tightly, bake covered first so the potatoes steam through, then uncover and finish at higher heat (or under the grill) for the last 10–15 minutes.
How long will leftovers keep?
Keep in a sealed container in the fridge for up to 3 days. Reheat in an oven (160°C) rather than the microwave for best texture.
