Essential Ingredients for Your Seafood Filling

Assemble fresh fillets, cooked prawns and a few basic staples to build the flavourful heart of this recipe.

Fresh Seafood Selection

Gather 400g salmon fillets and 300g white fish, removing skin and bones so each piece stays intact in the filling. Add 150g smoked haddock and 150g cooked prawns for extra texture and depth.

Choose firm, chilled fish to avoid flakes breaking up while you stir. The mix of salmon, haddock and white fish gives a rich, layered taste that defines this mary berry recipe.

Pantry Staples

For the sauce you will need 500ml milk, 25g butter and 25g plain flour to make a smooth roux. Season with salt and freshly ground pepper plus a splash of lemon juice to brighten the filling.

Consider stirring in fresh spinach or sliced leeks for colour and nutrition. Finish with 2 tbsp chopped dill or parsley and use a large pan to combine ingredients gently so pieces keep their shape.

• Check weights: 400g salmon, 300g white fish, 150g smoked haddock, 150g prawns.
• 500ml milk; 25g butter and 25g flour for the sauce.
• Salt, ground pepper, lemon juice and 2 tbsp dill to season.

Preparing the Perfect Mashed Potato Topping

Preparing potatoes with care ensures a stable, attractive top that browns evenly in the oven.

Boil 1kg of potatoes in salted water for 15–18 minutes until they are tender enough to mash easily. After cooking, be sure to drain well so excess water won’t dilute the mash and make the topping runny.

Mash the hot potatoes with 50g of butter and 100ml of warm milk or cream to create a smooth, rich texture. Season with salt and pepper to taste — this balances the richness of the filling beneath the top.

For a firm topping that will not sink, aim for a slightly drier mash rather than a loose one. Using a potato ricer gives a finer result and helps the mash sit neatly on the filling.

• Create ridges on the top with a fork to encourage browning around the edges.
• A well-made potato topping is the hallmark of a great fish pie and gives a comforting contrast to the tender seafood below.

Step by Step Cooking Instructions

With careful timing and gentle handling you can keep the fish pieces intact and finish with a golden mash top.

Poaching the Fish

Begin by poaching the salmon, white fish and smoked haddock in 500ml of milk for 5–6 minutes. Keep the heat low so the fillets cook gently and stay in neat pieces.

Remove the fish with a slotted spoon and set aside. Reserve the poaching liquid — this hot milk adds flavour to the sauce.

Creating the Roux

In a large pan, melt 25g of butter over low heat. Stir in 25g of flour and cook for one minute to form a roux.

Gradually whisk the reserved hot milk into the roux until smooth. Season with salt, ground pepper and a splash of lemon juice to brighten the sauce.

Assembling the Layers

Place the poached pieces into a baking dish. If using hard-boiled eggs, tuck them among the fish now.

Pour the sauce over the filling, then spread the prepared potato mash on top. Use a fork to create ridges that will brown.

1. Preheat the oven to 200°C.
2. Bake the assembled pie for 25–30 minutes until the top is golden and the sauce is bubbling.
3. Allow the dish to rest for 5 minutes before serving so the sauce can set.

Expert Tips for a Velvety Sauce

Getting the sauce just right takes patience but rewards you with a silky finish that complements the filling.

Troubleshooting Common Texture Issues

Whisk gradually. Add the milk a little at a time while whisking to stop lumps forming in the roux. Cook the flour and butter over low heat for at least one minute so the raw taste disappears.

If the mixture seems too thin, keep it on the pan and simmer until it coats the back of a spoon. This should take a few extra minutes and gives a stable base for the potatoes.

• To avoid a lumpy sauce, whisk milk slowly into the roux.
• Cook flour and butter over low heat for at least one minute.
• Thicken the sauce until it coats a spoon before combining with the fish.
• Let both sauce and mash cool slightly so the topping does not sink.
• Add a squeeze of lemon to brighten the sauce and lift the flavour of the fish.

If fillets are overcooked, cut a few minutes from the poaching time and allow oven residual heat to finish the job. A good whisk and steady heat are your best tools during cooking.

Creative Variations to Customise Your Dish

A few clever swaps in the filling or topping will personalise the dish without complicating the method.

For extra greens, fold steamed spinach or peas into the filling. They add colour, vitamins and a bright contrast to the creamy sauce.

Swap smoked haddock for smoked salmon if you want a lighter smoky note. Alternatively, increase white fish pieces to keep the dish leaner and still satisfying.

Change the topping by using sweet potato mash for a subtle sweetness, or sprinkle 50–70g grated cheddar over the mash for a golden crust. Using leeks instead of onions gives a sweeter, gentler base flavour.

• Try dill or chives in place of parsley to alter the aromatic profile.
• Swap prawns for extra white fish pieces to reduce richness while keeping texture.
• Add 1–2 tbsp lemon juice or a twist of lemon zest to brighten the filling before baking.

These small changes keep the heart of the mary berry recipe intact while making each bake feel fresh and personal.

Storing and Reheating Your Leftovers

Proper cooling and airtight storage preserve both texture and flavour for the next meal. Allow the pie to cool completely before covering so condensation does not make the potatoes soggy.

Fridge: Transfer portions to an airtight container and refrigerate for up to 2 days. This keeps the sauce and filling at their best and protects the delicate fish from overcooking.

Freeze: For longer storage, freeze the unbaked dish for up to 3 months. Freezing before baking preserves the texture of the sauce and milk-based elements.

• Reheat in the oven at 180°C for 20–25 minutes until piping hot in the centre — this protects the fish quality.
• Avoid reheating more than once to prevent the filling and sauce from breaking down.
• Microwave in short bursts if needed, stirring occasionally so heat distributes evenly.
• To refresh a chilled topping, use an air fryer at 160°C for 8–10 minutes to restore a golden finish.

Simple storage and reheating make it easy to enjoy this mary berry fish pie again with minimal fuss.

Ideal Side Dishes for a Complete Meal

Choose sides that bring colour and acidity to offset the creamy filling and golden topping.

Steamed greens such as broccoli, green beans or spinach add a fresh contrast to the rich potato topping. They steam in minutes and keep the plate light.

A crisp side salad dressed with a light lemon dressing cuts through the sauce and brightens each mouthful. The acidity works especially well with salmon and haddock in the main dish.

Roasted carrots bring sweetness and colour while peas offer a classic, family-friendly option. Both are simple to prepare and pair naturally with the oven-baked flavours.

• Serve crusty bread for soaking up any remaining sauce.
• Try steamed spinach or shredded leeks lightly sautéed in 1 tbsp olive oil for extra greens.
• Finish salads with a squeeze of lemon to lift the whole meal.

Tip: Combine two sides — a green vegetable and a bright salad — to make a balanced, satisfying plate in under 10 minutes.
