Smoked Haddock Fishcakes with Crispy Crumb

Flaky smoked haddock folded through buttery mashed potato, shaped and fried until deeply golden. A proper British teatime classic that's simpler than it looks and endlessly adaptable.

Smoked haddock fishcakes are the kind of supper that feels far more impressive than the effort involved. Gently poached haddock is flaked through soft mash with parsley, mustard and lemon, then crumbed and fried to a shattering golden crust. Make the mix ahead, chill it firm, and you’ve a cracking midweek meal or weekend brunch.

Ingredients

• 500 g floury potatoes — Maris Piper or King Edward, peeled and chunked
• 400 g smoked haddock fillet — undyed, skin on
• 300 ml whole milk — for poaching
• 1 bay leaf
• 25 g butter
• 2 tbsp chopped fresh parsley
• 2 tsp Dijon mustard
• 1 lemon — zest of whole, plus wedges to serve
• 3 spring onions — finely sliced
• 100 g plain flour — seasoned, for coating
• 2 eggs — beaten
• 120 g panko breadcrumbs
• 4 tbsp sunflower oil — for frying

Method

1. Put the potatoes in a pan of cold salted water, bring to the boil and simmer for 15 minutes until tender. Drain well, return to the pan for a minute to steam off, then mash smoothly and leave to cool.
2. Meanwhile, lay the haddock in a wide pan with the milk and bay leaf. Bring to a gentle simmer and poach for 4-5 minutes until the fish flakes easily and is opaque all the way through with no translucent patches. Lift out, discard the skin and bay, and flake into large chunks.
3. Beat the butter, parsley, mustard, lemon zest and spring onions into the cooled mash and season well. Gently fold through the flaked haddock, keeping some chunks intact. Taste and adjust the seasoning.
4. Divide into 8 and shape into thick patties. Sit them on a plate or tray and chill for at least 30 minutes to firm up, which stops them breaking apart in the pan.
5. Set out three bowls: seasoned flour, beaten egg, and panko. Coat each fishcake in flour, then egg, then press firmly into the crumbs to cover all over.
6. Heat the oil in a large frying pan over a medium heat. Fry the fishcakes for 3-4 minutes each side until deeply golden and crisp, and piping hot all the way through. Work in batches so you don't crowd the pan.
7. Drain briefly on kitchen paper and serve straight away with lemon wedges.

Serve it with

• A poached egg on top for brunch
• Buttered wilted spinach
• A crisp green salad with a mustard dressing
• Homemade tartare sauce
• Minted garden peas
• Wilted watercress and lemon

Why this works

Chilling the shaped cakes firms the mash so they hold together, while the panko crust fries crisper and lighter than ordinary breadcrumbs. Poaching the haddock in milk keeps it moist and mellows the smoke.

Common swaps

• Swap smoked haddock for salmon, or a mix of both
• Use cooked, cooled leftover mash to save time
• Sweet potato mash gives a sweeter, softer cake
• Add a pinch of cayenne or a little grated horseradish for warmth
• Gluten-free? Use GF flour and gluten-free breadcrumbs

Common mistakes to avoid

• Skipping the chill time, so the cakes fall apart when fried
• Using waxy potatoes or over-wet mash, which makes a claggy mixture
• Overworking the fish so it turns to paste instead of keeping flakes
• Frying in oil that's too hot, browning the crumb before the centre heats through

Storage, freezing & reheating

Storage: Keep cooked fishcakes covered in the fridge for up to 2 days. Uncooked, crumbed cakes also keep chilled for a day before frying.

Freezing: Freeze the crumbed, uncooked fishcakes on a tray until solid, then bag for up to 2 months. Cook from frozen, adding a few extra minutes per side over a lower heat.

Reheating: Reheat in a 200C oven for 12-15 minutes until crisp and piping hot throughout; avoid the microwave, which softens the crust.
