Shepherd’s Pie with Buttery Mash
Why this recipe works
- Deep savoury base: Browning the lamb, cooking out the flour, and simmering with tomato purée, Worcestershire sauce and stock creates a rich gravy that holds the filling together.
- Fluffy buttery mash: Steam-drying the potatoes before mashing helps prevent wateriness, giving the topping a lighter texture with enough structure to brown in the oven.
- Classic balance: The contrast between savoury lamb filling and smooth mashed potato is what makes shepherd’s pie so satisfying and recognisable.

Authenticity notes
- Lamb is the defining ingredient: Shepherd’s pie is traditionally made with lamb; a similar pie made with beef is more commonly known as cottage pie.
- Built for family-style serving: The dish is usually baked in one dish and spooned at the table, where the gravy settles into the mash as it rests.
Texture tips
- Steam-dry the potatoes: Returning drained potatoes to the hot pot briefly helps drive off excess moisture before the milk and butter are added.
- Rough up the topping: Scoring the mash with a fork creates ridges that catch the heat and brown more readily during baking.
Make-ahead tips
- Assemble in advance: The pie can be assembled ahead once the filling and mash are cool, then covered and refrigerated before baking.
- Reheat gently: Reheat covered in a 180°C (355°F) oven until piping hot throughout, uncovering towards the end if the top needs more colour.
- Freeze after cooling: Cool completely before freezing in an airtight container, then defrost overnight in the fridge before reheating.
Common mistakes
- Thin gravy: Let the lamb mixture simmer until it looks glossy and lightly thickened; a loose filling can seep through the mash.
- Serving too soon: Resting the pie briefly after baking helps the filling settle, making it easier to spoon cleanly.

Instructions
- Heat the oven to 200°C (390°F). Peel the potatoes and cut into even chunks.
- Put the potatoes in a large pot, cover with cold water and bring to the boil. Simmer for 15 to 18 minutes until very tender when pierced with a knife.
- Meanwhile, melt the butter in a large frying pan over medium heat. Finely chop the onion and dice the carrots, then cook with the thyme sprigs for 8 to 10 minutes until softened.
- Add the minced lamb and cook for 6 to 8 minutes, breaking it up, until browned and no longer pink. Stir in the flour and cook for 1 minute to remove the raw taste.
- Stir in the tomato purée and Worcestershire sauce, then gradually pour in the beef stock, stirring until smooth. Simmer for 10 to 12 minutes until the gravy is rich and lightly thickened, then stir in the peas for the final 2 minutes.
- Remove and discard the thyme sprigs, then spoon the lamb filling into a baking dish. Taste and adjust seasoning if needed.
- Drain the potatoes well and return them to the hot pot for 1 minute to steam-dry. Warm the milk, then mash the potatoes with the milk and butter until smooth and fluffy.
- Spoon the mash over the lamb filling and spread to the edges to seal. Rough up the surface with a fork, then bake for 20 to 25 minutes until bubbling at the edges and lightly browned on top.
- Rest for 5 minutes before serving so the filling settles slightly. Serve hot.
Recipe notes
Tips
- For a deeper, more savoury gravy, let the lamb mixture simmer until it coats the back of a spoon before adding the peas.
- For a crispier top, run the pie under a hot grill for 2 to 3 minutes at the end, watching closely so it does not catch.
Substitutions
- Replace Fresh thyme with 1 tsp Dried thyme, added with the onion and carrots.
- Replace Beef stock with Chicken stock for a slightly lighter gravy.
Storage
- Refrigerate up to 3 days
- Cool completely, then cover and refrigerate. Reheat in a 180°C (355°F) oven for 25 to 30 minutes until piping hot throughout; cover loosely if the top browns too quickly. Freeze in an airtight container for up to 2 months and defrost overnight in the fridge before reheating.
