Essential Ingredients for Your Fish Pie

Start by choosing quality produce — this step sets the tone for a reliable, tasty dish.

Protein mix: Use 900g of a high-quality fish mix containing salmon, cod and haddock fillets. Including a little fresh salmon lifts texture and flavour and helps the filling feel special without fuss.

Selecting the best fillets

Pick firm, glossy fillets from a trusted seller. Fresh white fish and a touch of salmon give a balanced taste and flaky texture. Aim for even-sized pieces so everything cooks at the same rate.

Choosing fresh vegetables

Buy 2 medium leeks, trimmed and thinly sliced. Gently cook them in 40g unsalted butter to release sweetness and avoid bitterness.

Sauce essentials: For a smooth, creamy base you will need 500ml milk and 40g plain flour to make a stable roux. These simple ingredients form the backbone of the sauce and bind the filling together.

• 900g fish mix (salmon, cod, haddock)
• 2 medium leeks, trimmed and sliced
• 500ml milk, 40g plain flour, 40g unsalted butter

Preparing the Perfect Potato Topping

Start by preparing the potatoes so they form a chunky, golden topping that crisps in the oven.

Place 800g small potatoes in a pan of cold, potatoes salted water and bring to the boil. Cook for 15–20 minutes until the pieces are tender and mashable.

Once cooked, drain well and return the tubers to the pan. Crush them gently with a fork to create a rustic, chunky mash — not too smooth.

Season the mash with a few turns of the mill for salt pepper. Drizzle in 2 tbsp olive oil and a little lemon juice, then taste and adjust.

Spread the mashed potato topping evenly over the filling so the top browns beautifully in the oven. If you need to, set aside the mash briefly while you finish the filling.

• Boil potatoes salted for 15–20 minutes.
• Drain well and crush into rustic mashed potatoes.
• Season, oil and spread to brown on top.

Creating the Creamy Fish Filling

The filling starts with tender leeks, a light roux and steady whisking to create a smooth sauce.

First, melt 3g unsalted butter in a large skillet and cook the sliced leeks over low heat for a few minutes until softened.

Mastering the Roux

Add 40g flour to the butter and stir flour in for about 1 minute to form a pale paste. This step removes raw flour taste and gives the sauce body.

Gradually pour in 500ml milk while whisking constantly. Keep the heat gentle and cook until the sauce thickens and is glossy.

Fold in 900g fish mix, including salmon and haddock, and cook for a couple of minutes so the pieces just start to flake. Stir through a handful of spinach until wilted.

• Season with salt pepper, lemon zest and chopped dill.
• Keep the sauce warm, not boiling, for the best texture.

Assembling and Baking Your Dish

Fill a 2-litre baking dish with the creamy mix and level it so the potato topping sits evenly. Spoon the filling in gently, making sure pieces of fish are distributed across the base.

Top the filling with the crushed mashed potatoes so the entire surface is covered. This ensures a crisp, golden potato topping that seals in the sauce as it bakes.

Place the dish in a 200ºC (fan 180ºC) preheated oven. Bake for 30–40 minutes until the mashed potatoes are golden and the filling bubbles at the edges.

Remove the baking dish and let the pie rest for 10 minutes. Resting lets the sauce settle so slices hold their shape when served.

• Use a suitable baking dish to guarantee even cooking and the right depth for the filling.
• Check the top in the last few minutes to avoid over-browning.

Cooking Methods for Modern Kitchens

Modern kitchens make this dish easy to cook whether you favour a full oven or an air fryer. Both methods brown the topping and set the sauce, but timings and space matter.

Using the Oven

Preheat your oven to 200ºC (fan 180ºC). Use a suitable baking dish so heat spreads evenly and the filling cooks through.

Remember to boil potatoes salted water for 15–20 minutes, then drain well and set aside before you assemble. Cook the leeks over low heat minutes first so they become sweet and tender; this helps the milk-based sauce taste mellow and well rounded.

“A well-preheated oven gives the best rise and golden top.”

Air Fryer Adaptations

If you own a Ninja Megazone, set it to 170–180°C and cook for 25–35 minutes. Check the basket clearance: the baking dish must fit comfortably to allow air to circulate.

Use the same prep steps — boil potatoes salted, drain well and set aside — and keep an eye on browning. The air fryer often shortens baking time, so check early to avoid overcooking.

Tip:Let the pie rest briefly after cooking so the sauce firms up and slices hold shape.

Expert Tips for Success

A few practical tricks will help you keep the filling intact and the topping crisp.

Add fish pieces at the final stage of cooking the sauce so the fillets hold their shape and do not flake apart. Gently fold them in and warm through for only a few minutes.

If your mash tastes bland, boost it with a little extra salt and pepper. A touch more butter or a splash of milk will round the flavour if needed.

To make the dish lighter, swap full-fat dairy for semi-skimmed milk and cut back slightly on butter in the mash. This keeps the sauce creamy without extra richness.

Stir a teaspoon of mustard into the sauce for depth; it pairs especially well with salmon and haddock. For a crunchy finish, use a fork to texture the mashed potato topping before baking.

• Keep the sauce warm, not boiling, before adding fish.
• Check seasoning of mashed potatoes and adjust salt pepper.
• Use an oven-safe baking dish to ensure even baking.

Serving Suggestions and Pairings

A few well-chosen accompaniments lift this comforting dish into a full, satisfying meal. These sides add freshness, colour and texture to the creamy filling and rustic potato topping.

Ideal vegetable sides

Greens and peas

Serve steamed greens or buttered peas for bright flavour and a fresh bite. The lightness contrasts well with the rich sauce and mash.

Salads and roots

A simple mixed salad with a lemon dressing helps cut through the creaminess. Roasted carrots add natural sweetness that pairs nicely with the softened leeks.

Starches and finishing touches

Crusty bread is useful for mopping up any remaining sauce. Allow the pie to stand for a few minutes before serving so the mash and filling settle into a neat slice.

Conclusion

Simple steps and smart prep turn this recipe into a dependable family favourite. The creamy filling, tender fish and rustic potato topping combine to make a comforting dish that suits busy nights and special Sunday suppers.

You can assemble ahead and chill before baking to save time. When ready, pop the dish into the oven and let the topping go golden for the last 25–35 minutes so everything sets and the flavours meld.

Mastering the baking temperature and a short resting time gives neat slices and a smooth sauce. This approach makes the pie reliable for the whole family and easy to serve.

Enjoy creating this warm, satisfying dish and sharing it with loved ones for a memorable meal.
