Creamy Lemon Fish Pie Recipe

The beauty of this recipe is that you can use any type of fish. Use half-fat cream if you want to cut down on the fat content. And you can also use mashed sweet potato or even a mix of carrot and floury potatoes for the topping. Serve with mixed greens on the side. 

Serves: 4
Prep Time: 15 minutes
Cook Time: 60 minutes


  • 1kg ­ floury potatoes
  • Salt and black pepper
  • 350ml milk
  • 130g butter, plus extra for baking
  • 60g ­ flour
  • ½ tsp mustard powder
  • Pinch of nutmeg
  • 750ml cream
  • 3-4 tbsp lemon juice
  • 1 tbsp parsley leaves, chopped, plus extra for topping
  • 1 tsp dill, chopped
  • 500g boneless fish, cut into 4cm chunks
  • 100g peeled prawns


  1. Place the potatoes in a large pot and cover with water. Add two teaspoons of salt and bring to the boil. Cook for about 20 minutes until the potatoes are soft. Drain well, then add the milk and half of the butter. Mash the potatoes until smooth, then season well with salt and pepper.
  2. Preheat the oven to 200°C/180°C fan/gas mark 6. Melt the remaining butter in a saucepan over a medium heat. When the butter starts to foam, whisk in the ‑ flour for about one minute. Whisk in the mustard powder and nutmeg.
  3. Gradually whisk in the cream until smooth and thick. Season well to taste.
  4. Leave to cool slightly, then stir in the lemon juice, parsley and dill.
  5. Pour about half of the sauce into a shallow baking dish. Top with the  fish and prawns, then pour over the remaining sauce.
  6. Spread the mashed potato over the  filling, adding a few dots of butter on top. Bake for 25-30 minutes until the mixture is bubbling at the sides and golden brown on top.
