What is shepherd's pie?

Shepherd's pie is a traditional British baked dish made with minced lamb and vegetables in gravy, topped with mashed potato. The name makes sense once you remember that shepherds look after sheep, and lamb is the key ingredient. Beef versions are called cottage pie.

The dish developed as a thrifty way to use leftover roast meat, mixed with onions and gravy and covered with mashed potato. Today it is usually made with fresh mince, which is quicker, but the idea of a filling topped with mash has not changed in generations.

Ingredients for this shepherd's pie recipe

This shepherd's pie recipe serves four to six people.

• 500 g minced lamb
• 1 tbsp olive oil
• 1 large onion, finely chopped
• 2 carrots, finely diced
• 1 celery stick, finely chopped
• 2 garlic cloves, crushed
• 2 tbsp tomato purée
• 1 tbsp plain flour
• 300 ml lamb or beef stock
• 1 tbsp Worcestershire sauce
• 2 sprigs of fresh thyme
• 100 g frozen peas
• 900 g floury potatoes, such as Maris Piper or King Edward
• 50 g butter and 3 tbsp milk, for the mash
• 50 g mature Cheddar, grated (optional)

How to make shepherd's pie step by step

1. Boil the potatoes. Peel and chop the potatoes, put them in cold salted water and boil for 15 to 20 minutes until tender.
2. Brown the mince. Heat the oil in a large, deep pan and fry the lamb over a high heat for 5 to 8 minutes until deeply browned. Spoon off excess fat.
3. Add the vegetables. Lower the heat and add the onion, carrots, celery and garlic. Cook for 8 minutes until soft.
4. Build the gravy. Stir in the tomato purée and flour, cook for a minute, then add the stock, Worcestershire sauce and thyme. Simmer for 25 minutes until thick, adding the peas for the last 5 minutes.
5. Mash. Drain the potatoes well, return them to the pan to steam dry for a minute, then mash with the butter and milk until smooth. Season well.
6. Assemble and bake. Preheat the oven to 200°C (180°C fan, gas 6). Tip the filling into an ovenproof dish, top with the mash, rough it up with a fork and scatter over the cheese. Bake for 25 to 30 minutes until golden and bubbling.

Tips for the best shepherd's pie recipe

• Brown the mince properly. This step builds the deep savoury flavour.
• Chop the vegetables finely so they melt into the sauce.
• Use floury potatoes and let them steam dry for a fluffy mash.
• Reduce the sauce until thick. A thin gravy will leak into the mash.
• Rough up the surface of the mash with a fork for crisp, golden ridges.

Choosing and cooking lamb mince

Lamb mince comes in regular and lean versions. Regular mince has more fat, which adds flavour but needs draining after browning; lean mince is lighter but benefits from a splash of extra stock. Buying from a butcher lets you ask for a coarser mince, which gives a better texture.

If you have leftover roast lamb, chop it finely and use it instead, adding it to the sauce at the end of the simmering time. That is how the dish began, after all, and it works beautifully.

Common shepherd’s pie problems and fixes

The filling is watery. Simmer it for longer, uncovered, until the sauce clings to the mince. Add the peas at the end.

The mash is gluey. This happens when potatoes are overworked or blended. Mash by hand and add the warm milk gradually.

The pie is greasy. Lamb mince can be fatty. Spoon off excess fat after browning, or choose a leaner mince.

The topping sinks. Let the filling cool for 10 minutes before topping, and spread the mash gently from the edges inwards.

Shepherd's pie variations

• Cheesy: mix 100 g grated Cheddar into the mash.
• Sweet potato: replace half the potatoes with sweet potato.
• Vegetarian: use green lentils and mushrooms instead of lamb, with vegetable stock.
• Red wine: add 100 ml red wine with the stock for a richer sauce.
• Leek and root veg: add diced leek, swede or parsnip to the filling.

Make ahead and freezing

Shepherd's pie is ideal for making ahead. Assemble the pie, cover it and keep it in the fridge for up to 24 hours before baking, adding 10 minutes to the cooking time.

To freeze, cool the baked or unbaked pie completely, wrap it well and freeze for up to three months. Defrost overnight in the fridge and reheat at 180°C until piping hot throughout.

What to serve with shepherd’s pie

A simple side of peas, green beans or buttered cabbage is all you need. For a more traditional meal, serve it with braised red cabbage and extra gravy at the table. If you want a vegetable-heavy supper, a leafy salad with a sharp dressing cuts through the richness.

Final thoughts

A great shepherd's pie recipe is all about deep flavour and good mash. Brown the lamb, reduce the sauce and finish with a golden topping, and you have a dish that comforts and feeds a crowd. Read more about this comforting dish in this overview of shepherd's pie.
