This fish pie combines flaky white fish, smoked fish, and prawns in a creamy sauce, topped with buttery mashed potatoes. Mary Berry’s version is rich and indulgent, making it a standout dish during the holiday season. It’s the perfect combination of creamy textures and delicious flavors.
Preheat your oven to 200°C (400°F).
In a saucepan, heat the milk gently and add the white fish and smoked fish. Poach for 5 minutes, or until the fish starts to flake. Remove the fish, reserving the milk, and set aside.
In the same saucepan, melt the butter and stir in the flour to form a roux. Gradually add the reserved milk, whisking continuously, until the sauce is smooth and thickened. Stir in the leeks, parsley, nutmeg, and seasoning.
Flake the poached fish into bite-sized pieces and combine it with the cooked prawns in the sauce. Pour the mixture into a baking dish.
Boil the potatoes until tender, then drain and mash with butter and cream. Season with salt and pepper, and spread the mash evenly over the fish filling. Use a fork to create decorative ridges on the surface.
Sprinkle grated cheese over the mashed potato if desired for a golden crust.
Place the baking dish in the oven and bake for 25-30 minutes, or until the top is golden and bubbling.
Let the pie cool for a few minutes before serving. Garnish with extra parsley for a festive touch.
