FAQs about this Easy Fish Pie recipe
Why does fish pie sometimes go watery?
This can often happen when your mashed potatoes are too soft to start with, they need to be left a little thicker than normal.
It can also happen if your fish is fresh and gives off water as it cooks. But honestly? I think a tiny bit of water in the sauce is worth it rather than having overcooked fish or having the extra step of pre-cooking the fish.
Is this gluten free?
If you use gluten free breadcrumbs (or omit them), this recipe is gluten free.
Do I really not need to cook the fish before putting into the pie?
Nope. I really think if you do it a) overcooks the fish and b) is just another step that we don’t need in our life.
Just be sure to check that the pie is hot all the way through before serving (push a metal knife into the middle and when you pull it out it should be burning hot OR better still use a meat thermometer).
Can I make fish pie in advance?
Yep. I prepare it all up to the stage where you would put it into the oven. Then it will keep in the fridge for up to 24 hours.
When you come to cook it, it will take about 10- 15 minutes longer to cook than if you were using a sauce/potatoes that’s already warm.
As above, just check that it is hot all the way through before serving.
Can you freeze this recipe?
Yes, you can freeze this pie. I tend to make it all up to the point where you put it in the oven and then freeze.
Allow to defrost fully and then bake in the oven on the day you want to eat it.
Is this recipe suitable for toddlers and weaning?
Yes, my children were fed on this so much! Leave out the salt and you can freeze small, leftover portions and reheat before serving.

Ingredients
- 520 g Fresh fish pie mix (cod, salmon and smoked haddock) (2 x 260g Packs) See Note 1.
- 175 g Cooked prawns
For the topping:
- 1.25 kg Potatoes Peeled and cut into chunks.
- 3 tbsp Butter
- Sea salt and freshly ground black pepper
- 100 g Cheddar cheese Grated.
- 50 g Panko breadcrumbs
For the sauce:
- 400 ml Milk Full fat or semi-skim.

Instructions
- Preheat the oven to 180C.
- Put your potatoes, with a sprinkle of salt, in a pan of boiling water and cook for 10 minutes or until a knife slides in easily.
To make the sauce:
- While the potatoes are cooking, put the cornflour into a mug and mix with a small amount of the measured milk until it forms a paste.

- Add the chives and plenty of salt and pepper.
To make the pie:
- Put the raw fish pie mix and prawns into the bottom of a large dish. Pour over the sauce.
