Print Recipe

Mary Berry Luxury Fish Pie is a traditional British baked dish made from fresh mixed fish pieces coated in a creamy white sauce, often enhanced with herbs, lemon, and vegetables. The filling is topped with rich, buttery mashed potatoes and baked until golden. What makes it “luxury” is the combination of different fish types—including smoked fish—which adds depth, aroma, and a beautifully balanced savouriness. It’s warm, indulgent, and incredibly satisfying.

Ingredients

For the filling:

  • 400g salmon fillets, skin removed

  • 300g white fish (haddock or cod)

  • 150g smoked haddock, undyed

  • 150g cooked prawns (optional but traditional in luxury versions)

  • 1 small onion, finely chopped

  • 500ml milk

  • 25g butter

  • 25g plain flour

  • 1 teaspoon Dijon mustard

  • 2 tablespoons fresh parsley, chopped

  • Salt and black pepper, to taste

  • Optional: A splash of lemon juice for brightness

For the mashed potato topping:

  • 1kg potatoes, peeled and cubed

  • 50g butter

  • 100ml warm milk or cream

  • Salt and pepper, to taste

  • Optional: 50g grated cheddar for a cheesy crust

Instructions

  • Prepare the mashed potatoes – Boil 1kg potatoes in salted water for 15–18 minutes until soft. Drain and mash with 50g butter, milk/cream, salt, and pepper.

  • Poach the fish – Place salmon, white fish, and smoked fish in a pan with 500ml milk and simmer gently for 5–6 minutes until just cooked. Remove fish and reserve milk.

  • Flake the fish – Break into large chunks, removing any bones. Add prawns if using.

  • Start the sauce – Melt 25g butter in a saucepan, stir in 25g flour, and cook for 1 minute to form a roux.

  • Add the reserved milk – Slowly whisk in the poaching milk until a smooth, thick sauce forms.

  • Season the sauce – Stir in mustard, parsley, salt, pepper, and optional lemon.

  • Assemble the pie – Place fish pieces evenly in a baking dish, pour the warm sauce over the top, and spread gently.

  • Top with mash – Spoon mashed potatoes over the filling and smooth with a fork, creating ridges for crispness.

  • Bake to golden perfection – Bake at 200°C (400°F) for 25–30 minutes, or until bubbling and lightly golden on top.

  • Rest and serve – Let the pie sit for 5 minutes to firm up before serving.
