Fish Pie with Crushed Potato Topping

Mary Berry shares her salmon, hake and spinach fish pie with a crushed potato topping. This recipe and more can be found in her new cookbook, Cooks The Perfect.

Introduction

The filling for this fish pie is a tasty blend of spinach, salmon, and hake. Instead of putting a classic mash on top, I’ve used quickly crushed potatoes, drizzled with olive oil to make them crunchy.

Serves 6

Ingredients

75g (21⁄2oz) butter, plus extra for greasing
1 large leek, trimmed and cut into 5mm (1⁄4in) thick slices
50g (13⁄4oz) plain flour
600ml (1 pint) hot, full-fat milk
1 1/2 tbsp chopped fresh dill
finely grated rind of 1⁄2 lemon
salt and freshly ground black pepper
400g (14oz) hake fillet, skinned and cut into 2.5cm (1in) cubes
400g (14oz) salmon fillet, skinned and cut into 2.5cm (1in) cubes
200g (7oz) fresh spinach
For the topping:
800g (13⁄4lb) new potatoes, such as Charlotte, scrubbed
2 tbsp olive oil, plus 2 tsp for drizzling

Essential kit

You will need a 1.7–2 litre (3–31⁄2 pint) baking dish, about 25 x 18cm (10 x 7in) and 7.5cm (3in) deep.

Instructions

525 calories per serving

Special equipment: 1.7–2 litre (3–31⁄2 pint) baking dish, about 25 x 18cm (10 x 7in) and 7.5cm (3in) deep

1. Grease the baking dish with butter. Melt 50g (13⁄4oz) of the butter in a large pan over a medium heat. Add the leek and fry for 3 minutes or until softened but not browned. Stir in the flour and cook, stirring, for 1–2 minutes. Remove from the heat and gradually pour in the hot milk. Return to a medium heat and stir until boiling, thickened, and smooth. Stir in the dill, lemon rind, and some salt and pepper. Add the hake and salmon to the sauce. Cook over a low heat for 2 minutes, stirring gently twice, just to start cooking the fish.

2. Pour the fish mixture into the buttered baking dish and set aside to cool. You can prepare up to this point 1 day ahead and refrigerate overnight.

3. Melt the remaining butter in a large, non-stick, deep-sided frying pan or sauté pan over a medium heat. Add the spinach and cook, stirring, for 1 1⁄2 – 2 minutes or until it wilts. Drain thoroughly in a colander, pressing down with the back of a wooden spoon to extract excess moisture. Roughly chop and set aside. Preheat the oven to 200ºC (fan 180ºC/400ºF/Gas 6).

4. Meanwhile, make the topping: put the potatoes in a large pan of cold salted water and bring to the boil. Cover and simmer for about 15 minutes or until tender. Drain well. Return the potatoes to the pan and, using a fork, break the potatoes down into rough, chunky pieces. Stir in the olive oil and some salt and pepper.

5. Scatter the spinach on top of the cooled fish mixture, then spoon the potatoes over the spinach layer. Drizzle over the remaining 2 teaspoons of oil and bake for 30–40 minutes or until the pie is bubbling at the edges and the topping is golden and crispy.
