Three 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. Three 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 53 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 14 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. Preheat the oven to 200C/400F/Gas 6 (180C fan).
2. Step 2. Put the potatoes into a saucepan of cold salted water. Bring up to the boil and simmer until completely tender. Drain well and then mash with the butter and milk. Add pepper and taste to check the seasoning. Add salt and more pepper if necessary.
3. Step 3. For the fish filling, melt the butter in a saucepan, add the leeks and stir over the heat. Cover with a lid and simmer gently for 10 minutes, or until soft. Measure the flour into a small bowl. Add the wine and whisk together until smooth.
4. Step 4. Add the milk to the leeks, bring to the boil and then add the wine mixture. Stir briskly until thickened. Season and add the parsley and fish. Stir over the heat for two minutes, then spoon into an ovenproof casserole. Scatter over the eggs. Allow to cool until firm.
5. Step 5. Spoon the mashed potatoes over the fish mixture and mark with a fork. Sprinkle with cheese.
6. Step 6. Bake for 30-40 minutes, or until lightly golden-brown on top and bubbling around the edges.

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.
