Fish pie with soufflé crouton topping

A classic pie of fish in white sauce, topped with a simple bread and soufflé style topping.

Equipment: You will need a 1.5 litre/2½ pint shallow, wide-based, ovenproof dish.

• 50g/1¾oz butter, plus extra for greasing
• 1 leek, thinly sliced or chopped
• 50g/1¾oz flour
• 600ml/20fl oz hot milk
• 2 tbsp chopped fresh dill
• 2 tbsp lemon juice
• 350g/12oz fresh haddock, skinned and cut into evenly sized cubes
• 350g/12oz undyed smoked haddock, skinned and cut into evenly sized cubes
• 3 hard-boiled eggs, each cut into 4 or 8 wedges

For the soufflé topping

• 1 small (400g/14oz) loaf white bread (about 2-3 days old)
• 50g/1¾oz full fat cream cheese
• 75g/2½oz butter
• 75g/2½oz mature cheddar, grated
• 1 large free-range egg white
• salt and freshly ground black pepper
  • Grease a 1.5 litre/2½ pint shallow wide-based ovenproof dish with butter.
  • To make the fish pie, melt the butter in a saucepan, add the leeks and gently soften over a low heat until completely tender but not coloured.
  • Sprinkle in the flour and stir over a high heat for a minute. Gradually pour in the hot milk, stirring all the time until the sauce is smooth, thick and has come to the boil. Remove from the heat and add the chopped dill, lemon juice, fish and season with salt and pepper. Cook for two minutes, stirring. Remove from the heat.
  • Spoon into a 1.5 litre/2½ pint shallow wide-based ovenproof dish. Arrange the eggs on top of the sauce and press in gently. Level the top and set aside until cold. Cover with cling film and chill in the fridge for about an hour or until firm.
  • Preheat the oven to 200C/180C Fan/Gas 6.
  • To make the soufflé topping, remove the crusts from the loaf and discard. Cut into five slices then cut each slice into small cubes (about 1.5cm/¾in across). You will need 150g/5½oz of bread cubes.
  • Add the cream cheese, butter and cheddar to a saucepan, melt over a low heat until runny (the mixture may look curdled but do not worry). Set aside for a moment.
  • In a spotlessly clean bowl, whisk the egg white until stiff peaks form when the whisk is removed. Fold the eggs whites into the cheese mixture. Season with salt and pepper and carefully stir. Stir in the bread cubes so they are all coated in the mixture. Spoon onto the top of the chilled fish mixture so the cubes are in a single layer.
