James Martin Lancashire Hotpot​​

This James Martin Lancashire hotpot is classic British comfort food at its best, with fork-tender lamb in a rich, savoury gravy topped with buttery, crisp-edged potatoes. The slow bake gives you soft, melting layers underneath and a golden, lightly crunchy top that’s hard to beat. It’s an easy, steady recipe with simple prep, then the oven does the work. Set aside around 3 hours total time for the full slow-cooked flavour.

Ingredients

For the lamb filling

• 900g lamb shoulder or neck, trimmed and cut into 3cm chunks
• 2 tbsp plain flour
• 1 1/2 tsp fine salt
• 1/2 tsp freshly ground black pepper
• 2 tbsp vegetable oil or beef dripping
• 2 large onions, thinly sliced
• 2 medium carrots, sliced (optional)
• 2 garlic cloves, finely chopped
• 2 tsp fresh thyme leaves (or 1 tsp dried thyme)
• 2 bay leaves
• 500ml lamb or beef stock, hot
• 1 tbsp Worcestershire sauce

For the potato topping

• 900g floury potatoes (Maris Piper or King Edward), peeled
• 40g unsalted butter, melted
• Salt and black pepper, to season

To finish (optional)

• 1 tbsp chopped parsley

How to Make James Martin Lancashire Hotpot​​

• Prepare the oven: Preheat the oven to 160°C or 140°C fan. Set a shelf in the middle so the casserole cooks gently and the topping browns evenly later on.
• Coat the lamb: Put the lamb in a bowl and toss with the flour, salt, and pepper until lightly coated. This helps thicken the gravy as it bakes.
• Brown the lamb: Heat 1 tablespoon of the oil or dripping in a large, oven-safe casserole dish. Brown the lamb in batches so it sears rather than steams, then lift it onto a plate.
• Soften the onions: Add the remaining oil, then stir in the onions (and carrots, if using). Cook for 8 to 10 minutes until softened and lightly golden at the edges. Add the garlic and cook for 1 minute.
• Build the gravy: Return the lamb to the pot. Add the thyme, bay leaves, stock, and Worcestershire sauce. Stir well, bring to a gentle simmer for 2 to 3 minutes, then turn off the heat.
• Assemble the hotpot: Slice the potatoes thinly, about 2 to 3mm. Arrange them on top of the lamb in overlapping layers, starting at the outside and working inwards for a tidy finish.
• Season and butter the topping: Sprinkle the potato layer with a little salt and plenty of black pepper. Brush with the melted butter, making sure you catch the edges so they crisp up beautifully.
• Bake covered: Cover the casserole with a lid (or a tight layer of foil) and bake for 1 hour 45 minutes. This slow cook is what makes the lamb tender and the onions sweet.
• Brown and crisp the top: Remove the lid, increase the oven to 200°C or 180°C fan, and bake uncovered for 30 to 45 minutes until the potatoes are golden and crisp. If you want extra colour, pop it under the grill for 2 to 3 minutes, keeping a close eye.
• Rest before serving: Let the hotpot stand for 10 minutes. This helps the gravy settle so it serves neatly. Finish with chopped parsley if you like.

Tips

How do I stop the potato topping from staying pale?

Make sure you uncover the pot for the final bake and raise the oven temperature. Brushing the potatoes with melted butter (especially around the edges) makes a big difference to colour.

Why is my lamb still tough?

It simply needs longer. Keep the oven low and give it extra time, 20 to 30 minutes at a go. Lamb shoulder and neck become tender when they are cooked slowly until the collagen breaks down.

How do I prevent a watery hotpot?

Brown the lamb in batches and simmer the gravy briefly before topping with potatoes. Also keep the stock to 500ml to start. You can always add a splash more when serving if you prefer it looser.

Can I make the potatoes extra crisp?

Slice them evenly and don’t overlap too thickly. Finish uncovered at the higher temperature, and if needed, use the grill for a couple of minutes right at the end.

Serving Suggestions

• Pickled red cabbage or beetroot for a sharp contrast
• Butter-glazed peas or mushy peas
• Steamed greens like cabbage or kale
• Crusty bread to mop up the gravy

Storage

Room temperature

Let the hotpot cool for no more than 2 hours, then refrigerate. Because it’s meat-based, it’s not suitable to store at room temperature beyond that.

Refrigerator

Cool completely, cover, and refrigerate for up to 3 days. Reheat in the oven at 180°C (160°C fan) until piping hot throughout, usually 25 to 35 minutes depending on depth, or microwave individual portions until hot.

Freezing

Freeze in airtight containers for up to 3 months. Thaw overnight in the fridge, then reheat in the oven until piping hot. If the potato looks a little soft after thawing, finish uncovered for 10 minutes to refresh the top.

A hearty British Lancashire hotpot with tender slow-cooked lamb and onions in a rich gravy, finished with a crisp, buttery potato topping.

Ingredients

• For the lamb filling

• 900g lamb shoulder or neck, trimmed and cut into 3cm chunks

• 2 tbsp plain flour

• 1 1/2 tsp fine salt, plus extra for seasoning potatoes

• 1/2 tsp freshly ground black pepper

• 2 tbsp vegetable oil or beef dripping

• 2 large onions, thinly sliced

• 2 medium carrots, sliced (optional but lovely)

• 2 garlic cloves, finely chopped

• 2 tsp fresh thyme leaves (or 1 tsp dried thyme)

• 2 bay leaves

• 500ml lamb or beef stock, hot

• 1 tbsp Worcestershire sauce

• For the potato topping

• 900g floury potatoes (Maris Piper or King Edward), peeled

• 40g unsalted butter, melted

• Extra black pepper, to taste

• To finish (optional)

• 1 tbsp chopped parsley, to serve

Directions

• Preheat the oven to 160°C (140°C fan). Heat a large casserole dish and get all ingredients prepped.
• Toss the lamb with flour, salt and pepper. Brown in batches, then set aside.
• Soften onions (and carrots) in the same dish, then stir in garlic, thyme and bay.
• Return lamb to the pot, add stock and Worcestershire, then bring to a gentle simmer.
• Slice potatoes thinly and layer over the lamb mixture. Season and brush with melted butter.
• Cover and bake for 1 hour 45 minutes, then uncover, increase heat and bake until golden and crisp.
• Rest for 10 minutes before serving, then finish with parsley if you like.

Notes

• Slice the potatoes evenly for a neat, crisp topping. A mandoline makes this quick.
• Brown the lamb properly. That caramelisation is where the deep flavour comes from.
• If the topping colours too fast, lay a piece of foil loosely over the top for the last 15 minutes.
• Hotpot tastes even better the next day. Reheat gently until piping hot.
