Fish 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 seafood dish, Fish pie demands timing precision: the difference between perfect and overcooked is often less than 90 seconds, and the result of overshooting is a textural penalty there's no fixing.
Set your servings in the scaler above and every line of the recipe rewrites itself with smart fractions and unit promotion. Open Cook Mode to step through it hands-free with timers running.

Method
- 01.Put the potatoes in a large pan of cold salted water and bring to the boil. Lower the heat, cover, then simmer gently for 15 minutes until tender. Drain, then return to the pan over a low heat for 30 seconds to drive off any excess water. Mash with 1 tbsp olive oil, then season.
- 02.Meanwhile put the milk in a large sauté pan, add the fish and bring to the boil. Remove from the heat, cover and stand for 3 minutes. Remove the fish (reserving the milk) and pat dry with kitchen paper, then gently flake into an ovenproof dish, discarding the skin and any bones.
- 03.Heat the remaining oil in a pan, stir in the flour and cook for 30 seconds. Gradually stir in 200-250ml of the reserved milk (discard the rest). Grate in nutmeg, season, then bubble until thick. Stir in the cream.
- 04.Preheat the oven to 190°C/fan170°C/gas 5. Grate the artichokes and add to the dish with the leek, prawns and herbs. Stir the lemon zest and juice into the sauce, then pour over. Mix gently with a wooden spoon.
- 05.Spoon the mash onto the fish mixture, then use a fork to make peaks, which will crisp and brown as it cooks. Sprinkle over the cheese, then bake for 35-40 minutes until golden and bubbling. Serve with wilted greens.
Cooking notes
Scaling works best when you weigh ingredients rather than measure by volume — small differences in packing can compound at higher multipliers.
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 Fish pie
Fish 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.
Seafood is the most scaling-sensitive protein because the overcooking window is narrow and the penalty is steep. Scale Fish pie per piece if you can — cook three fillets in two batches rather than crowd the pan into one. Sauce-based seafood dishes scale linearly, but always taste before adding more salt: brininess from the seafood itself doesn't scale predictably.
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 — Fish 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 Fish pie is doing structurally — here's the practical version.
Substitution ideas
Heavy cream
For sauces and soups: evaporated milk + 1 tbsp butter per cup approximates the body and richness. For whipping, the solid layer from chilled full-fat canned coconut milk whips into stable peaks (the flavour is coconut-forward; works in tropical desserts, less so in vanilla applications).
Dairy milk
Unsweetened soy milk substitutes 1:1 in custards and baked goods (the protein content matches). Oat milk gives a creamier mouthfeel for soups and coffee drinks. Almond milk works for lighter applications. Skip coconut milk in savoury recipes unless the dish calls for it — the flavour is unmistakable.
All-purpose flour
For gluten-free, a 1-to-1 gluten-free baking blend (one that contains xanthan gum) is the most reliable swap. For texture variations: bread flour gives chewier results; cake flour gives more tender. Avoid almond or oat flour as a 1:1 swap — they don't form gluten and most recipes structurally depend on it.
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
Seafood is the worst-tempered category for make-ahead — texture and flavour both degrade quickly after cooking. Fish pie should ideally be cooked the day it's served. If a make-ahead is unavoidable, prep components (the sauce, marinade, vegetables, garnishes) the day before and cook the fish or shellfish at the last moment. Cooked seafood develops a pronounced fishy off-flavour within 24 hours even when properly refrigerated.
