Fish pie

Why this dinner works

Most weeknight one-pot dinners ask you to choose between two evils: a five-ingredient bowl that tastes like the inside of a saucepan, or a recipe so layered it eats your entire evening. Fish pie sits comfortably in the middle. It draws on British traditions where building flavor in stages — aromatics, then spice, then the slow swell of liquid into starch — is just how dinner gets made on a regular Tuesday.

The whole thing comes together in about 50 minutes in a single soup pot, which means dinner from idea to table is shorter than most podcast episodes. We've leaned on the everyday 15 ingredients listed below, but in the notes after the recipe you'll find the small swaps and shortcuts that make this dish forgiving when your fridge is half-empty.

Method

1. Step 1. 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.
2. Step 2. 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.
3. Step 3. 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.
4. Step 4. 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.
5. Step 5. 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.

Cook's notes

One pan, fewer dishes. Use the widest, heaviest soup pot you own with a tight-fitting lid. The wider base means faster browning at the start; the lid traps the gentle steam that finishes the dish without scorching the bottom.

Salt as you go. Season the aromatics, season the protein, season the liquid before it reduces. By the time you taste at the end, the only adjustment is usually acid — a squeeze of lemon, a splash of vinegar, a final crack of pepper.

Make it ahead. Like most one-pot dinners with british roots, the leftovers are arguably better the next day. Cool quickly, refrigerate within two hours, and reheat gently with a splash of water or stock to loosen things back up.

Pairings & serving

This one feels best in a 6-bowl spread with a sharp green salad and something cold to drink. If you want to stretch it for unexpected company, double the liquid and a single starchy ingredient — rice, pasta, potatoes, depending on the recipe — and the whole pan grows without much extra work.
