Method
Prep Your Spuds
- The first step of this process is to boil your peeled and cut potatoes in salted water until cooked through. Once soft, drain and mash them with a splash of warm milk, a good knob of butter, and a speck of salt and pepper. Set aside for later.
Poach the Fish
- Add your choice of fish fillets and pour ¾ of the milk into a large saucepan. Bring to the lowest simmer and poach for about 5–7 minutes or until the fish just starts to flake. Gently lift the fish out to a plate, reserving the milk for the sauce. Flake the fish into large pieces, discarding bones.
Make the Sauce
- In another pan, melt the butter over medium heat then add the chopped onion and cook until softened. Stir in the flour to make a paste (a roux), then whisk in the reserved poaching milk in stages until you have a smooth, silky sauce. Add the prawns (if using), dill and lemon zest, and season with salt and pepper. Taste and adjust as needed.
Assemble the Pie
- Gently fold the flaked fish into the sauce, being careful not to break it up too much. Spoon this mixture into a large baking dish and top with your mashed potatoes. Spread it evenly with a fork and create a bit of texture on top — this allows it to crisp up beautifully in the oven.
Bake & Serve
- Place the assembled dish in a preheated oven (190°C/375°F/gas 5) for about 30 to 40 minutes, or until the top is browning and the edges are bubby. Take out of the oven, let it rest for a little while, then dig in. A simple green salad or some bright, steamed greens on the side rounds out the meal.
