  • 350 g Mixed Diced Fish buy from frozen and defrost in fridge overnight
  • 1 Leek roughly chopped
  • 350 ml Milk
  • 20 g Butter
  • 20 g Plain Flour
  • 1 Vegetable Stock Cube
  • 1 tbsp Chopped Flat Leaf Parsley
  • 1 Lemon grated zest only


  • 600 g Maris Piper Potatoes  peeled and cut into large dice
  • 20 g Butter
  • 1 Egg Yolk
  • Salt and Pepper



  • In a non-stick pan, melt the butter and add the leek. Cook gently for 4 minutes, taking care not to burn the butter or the leek.
  • Add the flour and mix well. Stir over the heat for a minute or so.
  • Add the milk a little at a time, stirring well over the heat to form a smooth paste after each addition. Keep it moving so it does not burn.
  • When you have added all the milk, you should have a smooth sauce. Crumble in the stock cube, turn the heat right down and leave to gently cook for a couple of minutes.
  • Add the parsley and grated lemon zest and remove from heat.
  • Place the fish into an oven proof dish. Pour over the sauce and set aside until the topping is ready.


  • Preheat you oven to around 180C.
  • Place the potatoes in a large pan and cover with cold water. Add a little salt, place on the heat and bring to the boil. Turn down and gently simmer for 15-20 minutes.
  • When the potatoes are cooked (a fork should go through one with little resistance), remove from the heat and drain well.
  • Place back into the pan and place the pan on a very low heat to try and dry out the potatoes a little before mashing.
  • Mash the potatoes well until all the lumps are removed. Add the butter and melt in, then add the egg yolk and mix well.
  • Pipe or spoon the potato on top of the filling.
  • Sprinkle a little smoked paprika on top and place into the over.
  • Cook in the oven for 20-25 minutes until the top is nicely browned and everything is cooked through and piping hot.
