Swede and Potato Rosti Fish Pie

I have mentioned before that instead of buying fresh meat and fish all the time I buy frozen, because a) It saves money (its always a lot cheaper to buy frozen than fresh) and b) it saves waste, the amount of chicken, mince and fish I have thrown away because I forgot about it in the fridge, is ridiculous. This fish pie is a great way to get veg into the mouths of babes, not that we have any problem with that but for those of you with fussy eaters, the topping is a Rosti of swede and potato and you could always hide veg throughout the pie instead of on the side too!

What you need:

300g potatoes
1/2 medium swede
500g Frozen fish of choice
600ml milk 
50g Butter
2 leeks 
50g Plain Flour
Bunch Parsley (chopped)
1tsp English Mustard (add more or less to taste)
Grated Mozzarella

First of all peel and grate (thickly) your potatoes and swede, squeeze the excess liquid and cook through in a frying pan, stirring constantly, when 3/4 cooked pop to the side for later.

Next put your fish in a shallow pan and cover with the milk, bring your milk to a gentle simmer and cook for around 5-10 minutes. After this time take from the heat, remove the fish and put to the side you need to KEEP THE MILK, as it will be used for the sauce.

To make your sauce, melt the butter in a pan. Add the leeks and cook until softened. then sieve the flour over the top and stir into your leeks, remove from the heat and gradually add the milk you poached the fish in, stir constantly to avoid lumps.

Pop back on the heat and bring to the boil, reduce to a simmer and stir in the chopped parsley and English mustard.

Put the grill on medium and pull/cut your fish fillets into chunks and add to the sauce mixture before transferring to a oven proof dish, topping with the rosti mix and put under the grill for 10 minutes, for the final 5 minutes add a sprinkle of breadcrumbs and mozzarella.

Serve with a side of vegetables. (I served with tender-stem broccoli, baby carrots and sweetcorn.)
