Ingredients

Scale

For the Filling

  • 600g mixed fish (white fish, salmon, smoked haddock)

  • 150g cooked prawns (optional)

  • 1 leek, finely sliced

  • 50g butter

  • 50g plain flour

  • 600ml milk

  • 1 tsp Dijon mustard

  • 2 tbsp fresh parsley, chopped

For the Potato Topping

  • 1kg potatoes, peeled and chopped

  • 50g butter

  • 100ml warm milk or cream

  • Salt and pepper

  • Optional: handful of grated cheese for the top

Instructions

Step 1: Prepare the Mashed Potatoes

Boil potatoes until soft, then drain. Mash with butter, warm milk, salt, and pepper until smooth and fluffy.

Step 2: Cook the Leeks

Melt butter in a pan, add sliced leeks, and cook until softened and lightly fragrant.

Step 3: Make the Creamy Sauce

Sprinkle flour over the leeks and stir well. Slowly add milk, whisking continuously until thickened. Add mustard, parsley, salt, and pepper.

Step 4: Add the Fish

Cut the fish into chunks and stir gently into the sauce. Add prawns if using. Cook for a few minutes until slightly opaque.

Step 5: Assemble the Pie

Transfer the fish mixture into a baking dish. Spoon mashed potatoes on top, smoothing with a fork. Add grated cheese if desired.

Step 6: Bake Until Golden

Bake at 200°C (400°F) for 25–30 minutes until the top is golden and the sauce is bubbling.

Step 7: Serve Warm  

Allow the pie to rest briefly before serving for cleaner portions.
