Lamb and Potato pie
About this recipe
British cooking traditions favour generous root vegetables, slow-cooked meats, hearty puddings, and the kind of food that warms a damp island. The everyday repertoire prioritises preservation and shared family meals; the special-occasion repertoire (roast beef, Christmas pudding) is among the most globally recognised.
As a lamb dish, Lamb and Potato pie works the same braising-vs-fast-cooking divide as beef — lean cuts for hot fast cooking, tougher cuts for time-and-temperature stews where the flavour deepens.
Use the scaler above to set the number of servings you actually want to cook — quantities resize with culinary fractions, units promote sensibly (three teaspoons become a tablespoon), and the result reads like the recipe was written for your table.

Method
- Dust the meat with flour to lightly coat.
- Heat enough vegetable oil in a large saucepan to fill the base, and fry the onion and meat until lightly browned. Season with salt and pepper.
- Add the carrots, stock and more seasoning to taste.
- Bring to the boil, cover and reduce the heat to a simmer. Simmer for at least an hour or until the meat is tender. Take your time cooking the meat, the longer you leave it to cook, the better the flavour will be.
- Preheat the oven to 180C/350F/Gas 4.
- Add the drained potato cubes to the lamb.
- Turn the mixture into a pie dish or casserole and cover with the shortcrust pastry. Make three slits in the top of the pastry to release any steam while cooking.
- Brush with beaten egg and bake for about 40 minutes, until the pastry is golden brown.
- Serve.
Cooking notes
When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.
For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.
When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
Scaling notes
Scaling Lamb and Potato pie
Lamb and Potato pie is written for around four servings as it stands on this page — scaling it up for a party or down for a meal-for-one is the small math problem most home cooks face every week. Here's how this particular dish responds to scaling, what changes linearly, and what doesn't.
Lamb cooks similarly to beef but is leaner, which means scaling Lamb and Potato pie up calls for slightly longer rest time after cooking (proportional to thickness, not mass). Braises and stews scale linearly; roasts follow the cube-root rule — doubling a lamb leg adds about a quarter to the cook time, not double.
This recipe calls for eggs, which are the trickiest ingredient to scale to non-integer multiples. A US "large" egg weighs about 50 g; if a fractional scaling lands on, say, 1.5 eggs, beat one egg and weigh 25 g of the beaten mixture rather than guessing. The same goes for halving recipes — half an egg is 25 g of beaten egg, not a dramatic estimate.
When you scale the flour in this recipe, weigh it in grams if you can — a cup of flour can weigh anywhere from 113 g to 150 g depending on how you measure. The ScaleRecipe ingredient converter uses the King Arthur Baking reference of 120 g/cup for all-purpose flour, which is the same standard most modern baking books assume.

Beyond the recipe
Substitutions & make-ahead — Lamb and Potato pie
Two things home cooks ask about most when they're outside the recipe's exact assumptions: what swaps work for which ingredients, and how the dish behaves when you make it ahead. Both depend on what Lamb and Potato pie is doing structurally — here's the practical version.
Substitution ideas
Eggs
For binding (cookies, quick breads, meatballs): 1 large egg ≈ 1 tbsp ground flaxseed + 3 tbsp water, rested 5 minutes until gelled — structurally closest to a real egg. For moisture without structure (cakes, brownies): ¼ cup unsweetened applesauce or mashed banana per egg, accepting some loss of rise.
For weight-based swaps and arbitrary quantities, the ingredient density converter and the cup-to-grams chart cover most pantry staples.
Make-ahead and storage
Lamb behaves like beef for storage — braises and stews like Lamb and Potato pie (when it's in that family) improve overnight as the spice and acid components marry. Refrigerate in a wide shallow container; reheat gently with a splash of the cooking liquid. The stronger flavour signature lamb carries mellows during storage, which can be a feature (a milder leftover the next day) or a bug (the original character gets muted) depending on what you're after.
