Here, I show you how to make a delicious and easy unofficial Slimming World Fish Pie. It uses blended oats, milk and cheese as part of your allowances when serving 4 people.

I've wanted to make my own Slimming Fish Pie for so long! Years, in fact. But the reason I've never found the right time is that fish isn't everyone's favourite in our house.
I love cooking fish recipes for lunches (and so does my dog!) But my husband, not so much. So I whipped this up with enough portions to last three the next three days.
It's also a great meal to make ahead and freeze.

IS LOW FAT FISH PIE HEALTHY?
There's a well-known saying that floats around Slimming World meetings. And that is, "if it swims, it slims". Normally, Fish Pie is made with butter and flour to make a roux and sometimes with added cream.
However, I used my favourite blended oats and milk method to make a Syn Free roux. It's also infused with onions, bay leaves, mustard and seasoning. I also omitted the butter and thickened in the microwave over short bursts.
In total, it serves 4 large portions at approximately 368 calories each. It also uses oats, milk, and cheese as each person's allowance. I've also since created a Slimmer's cauliflower cheese sauce with this exact same method!

WHAT FISH DO I NEED FOR HEALTHY FISH PIE?
I like to make savings when I cook most of my meals. (Unless it's a special dessert). And while I went shopping for my healthy fish pie ingredients, I discovered the instant saving was to buy a prepacked fish pie mix.
Although it's dearer by the pound, it costs much more buying the fish separately. Or you could of course cut what you need of the following and freeze the rest for another meal.
- 130g smoked haddock
- 130g salmon
- 130g cod
- And prawns if you wish

CAN YOU FREEZE FISH PIE?
Yes, you can!
When there is a mashed potato topping on any of my recipes, I freeze before cooking.
That way, it avoids over burning the top. Or you could bake then reheat in the oven from frozen with tin foil. It's also up to you whether you want to add cheese before freezing or not.
