Creamy Fish Pie Recipe (NZ Style): A Comfort Food Classic Made Easy

When it comes to classic comfort food in New Zealand, few dishes can compete with a warm, hearty creamy fish pie. Packed with tender flaky fish, rich white sauce, and topped with buttery mashed potatoes, it’s a dish that feels like home. Whether you’re feeding the family on a weeknight or looking for something satisfying to meal prep for the week ahead, this creamy fish pie NZ style ticks all the boxes.

What Makes This a New Zealand-Style Fish Pie?

New Zealand’s abundant coastline offers an excellent range of fresh fish, making seafood a staple in many households. A creamy smoked fish pie NZ version is also popular, particularly in coastal towns, where smoked kahawai, trevally, or warehou are often used for added depth of flavour.

What sets the Kiwi-style fish pie apart is its simplicity and quality of fresh fish, especially locally sourced fish for maximum freshness and quality.

Ingredients

For the filling:

• 600g white fish fillets (e.g., hoki, tarakihi, snapper, or gurnard)

• Optional: 150g smoked fish (kahawai or warehou), flaked

• 1 small onion, finely chopped

• 2 tablespoons butter

• 2 tablespoons plain flour

• 2 cups whole milk

• 1 teaspoon Dijon mustard

• Salt and pepper, to taste

• 1/4 cup chopped fresh parsley

• Optional: 1/2 cup frozen peas or sweetcorn for added texture

For the mash topping:

• 700g floury potatoes (e.g., Agria), peeled and chopped

• 2 tablespoons butter

• 1/4 cup milk or cream

• Salt and pepper, to taste

Step-by-Step Instructions

1. Prepare the Fish

Start by poaching your fish gently in simmering water or milk for 4–5 minutes until just cooked through. If you’re using smoked fish, you can flake it directly without pre-cooking. Drain and allow the fish to cool slightly before flaking it into bite-sized pieces. Be sure to remove any bones.

2. Make the White Sauce

In a medium saucepan, melt the butter over a low heat. Add the chopped onion and sauté until soft and translucent, around 5 minutes. Stir in the flour and cook gently for 1–2 minutes to form a roux this gets rid of the raw flour taste.

Slowly whisk in the milk, a little at a time, ensuring there are no lumps. Keep stirring until the sauce thickens and becomes smooth. Add the mustard, salt, pepper, and parsley. If you’re including frozen peas or corn, stir them into the sauce now.

Add the flaked fish and gently fold it through the sauce, being careful not to break the fish up too much. The goal is a rich, creamy filling with visible chunks of fish.

3. Make the Mashed Potato Topping

Boil the potatoes in salted water until soft (about 15–20 minutes). Drain well and mash with butter and a splash of milk or cream until smooth and fluffy. Season to taste with salt and pepper.

4. Assemble the Pie

Preheat your oven to 180°C (fan bake). Spoon the fish filling into an ovenproof baking dish. Carefully top with the mashed potato, spreading it evenly to seal in the filling. For extra crispiness, rough up the surface with a fork and dot with a little extra butter.

5. Bake to Perfection

Bake in the oven for 25–30 minutes, or until the top is golden brown and the filling is bubbling at the edges. If you like an extra golden crust, you can finish it under the grill for 2–3 minutes.

Serving Suggestions

Serve your creamy fish pie NZ style with a side of steamed greens  think silverbeet, peas, or green beans. A wedge of lemon on the side adds a refreshing zing.

• Best fish to use: Hoki and tarakihi are affordable and hold up well in pies. Gurnard offers a slightly sweeter flavour. Adding a little smoked fish gives an authentic creamy smoked fish pie NZ twist.

• Avoid overcooking the fish: Poach it just until cooked. Remember, it will cook further in the oven.

• Add herbs: Parsley is classic, but you can also use dill or chives for extra flavour.
