Ingredients

  • 500 g white fish, e.g., cod or haddock *Or use a bag of frozen fish pie mix.
  • 200 g salmon
  • 200 g prawns, peeled and deveined
  • 1 kg potatoes, peeled and diced
  • 100 g butter
  • 200 ml cream *Can replace the cream with milk
  • 200 ml milk
  • 40 g flour
  • 150 g cheddar cheese, grated
  • 2 tablespoon fresh parsley, finely chopped
  • Salt and pepper to taste

Instructions

Preparing the Mashed Potatoes:

  • In a large pot, place potatoes, cover with water, and bring to a boil.
  • Boil for 15-20 minutes or until soft.
  • Drain and mash the potatoes using 50g of butter and a splash of milk. Set aside.

Making the Creamy Fish Pie Filling:

  • In a saucepan, melt 50g of butter over medium heat.
  • Stir in flour to form a roux, cooking for 1-2 minutes.
  • Gradually whisk in milk and cream (if using), stirring constantly until thickened.
  • Add the parsley and season with salt, and pepper.
  • Mix in white fish, salmon, and prawns into the saucepan, coating them well in the creamy sauce and remove the pan from the heat.

Assembling and Baking:

  • Preheat your oven to 200°C (400°F).
  • Pour the creamy fish pie filling from the saucepan into a large casserole dish.
  • Smoothly layer the mashed potatoes on top of the filling.
  • Sprinkle the surface with grated cheddar cheese.
  • Bake for 25-30 minutes or until the top turns golden brown.

Notes

Fish: Using frozen fish is fine, but make sure to fully thaw it first.
Cheese: For a lighter option, consider using low-fat cheddar.
Sauce Thickness: If the sauce feels too thick, add a splash of milk to thin it out; too thin, and a little more flour can help thicken it.
Cheese Alternatives: If you're not a fan of cheddar, Gruyère or Parmesan also work well as a cheesy topping.
Oven Temperatures: Ovens can vary. Keep an eye on the pie during the last 10 minutes of baking to avoid over-browning.
Gluten-Free: To make this dish gluten-free, use gluten-free flour for the roux and ensure all other ingredients are gluten-free.
Make-Ahead: The fish filling can be prepared a day in advance and stored in the fridge, covered. Assemble and bake the next day for an easy meal prep.
