Simple Fish Pie with Two-cheese Mash

Fish pies can get a bit complicated – so try this easy version, topped with heavenly cheesy mash. Yum!


Serves 4 / Prep time: 25 minutes / Cook time: 55 minutes


1kg potatoes, peeled and cut into large chunks

150g broccoli, broken into small florets

100g frozen peas

400g fish pie mix (smoked haddock, salmon and cod or haddock chunks)

50g (reduced from 100g) cooked peeled prawns, thawed if frozen

300ml tub crème fraiche

2 tbsp chopped fresh parsley

3 tbsp semi-skimmed milk

50g (reduced from 75g) mature Cheddar cheese, grated

50g (reduced from 75g) Red Leicester cheese, grated

Freshly ground black pepper



1 Preheat the oven to 190°C, fan oven 170°C, Gas Mark 5.

2 Cook the potatoes in gently boiling water for 20 minutes, until tender. At the same time, cook the broccoli in gently boiling water for 4-5 minutes, adding the frozen peas for the final 2 minutes. Drain the green vegetables thoroughly. 

3 Tip the fish pie mix and prawns into a baking dish and add the crème fraiche and parsley. Season with black pepper. Add the broccoli and peas and stir everything together.


4 Drain and mash the potatoes, then beat in the milk and season with pepper. Stir in most of the grated cheeses. Spoon on top of the fish mixture. Sprinkle the remaining cheese on top and bake for 30-35 minutes until golden brown.

Cook’s tips: Buying fish pie mix should work out cheaper than buying the fish separately - look out for it in the chill cabinet, or buy from the fish counter. You could just use one variety of cheese if you’d rather – though the combination works well for colour and flavour.
