If you are following the Slimming World plan and looking for delicious recipes, you’ve come to the right place! This Slimming World Fish Pie is made with Philadelphia (so no Quark here!) I personally do not like Quark, even though I know it is free! I’d rather use the Syns on this SW fish pie and use Philly.

However, I do give a few options, so if you want Syn free fish pie or one that has fewer Syns read on for the Slimming World fish pie recipe!

Slimming World Fish Pie

If you are one of the many people following the Slimming World (SW) plan and looking for some meal-time inspiration then look no further.

This recipe has been adapted from an official SW book that I had. I usually adapt recipes to suit my family’s personal tastes. So maybe leaving an ingredient out (e.g., mushrooms) or adding extras spices (e.g., more chilies), or making tweaks to the way it is made.

As mentioned, I make these recipes for my family as we are all trying to eat healthier and lose some weight. So you can rest assured that any changes I make are still going to be Slimming World friendly.

So for example, I wouldn’t replace 5% beef mince (Free) with 20% beef mince (not Free) or add olive oil to a recipe without including the Syn count.

All of the Slimming World-friendly recipes I share on The Purple Pumpkin Blog have been made by me and tried and tested by family.

Fish Facts

Health guidelines say we should eat two portions of fish per week, one of which should be oily fish, such as salmon or mackerel.

Most of us could probably include more fish in our diet – I know we could. We do often have grilled or steamed salmon once a week, but white fish not so often.

Fish that is steamed, baked or grilled is a healthier choice than fried fish. Frying can increase the fat content of fish and shellfish, especially if they’re cooked in batter.

To ensure there are enough fish to eat now and in the future, we should try to eat a wide variety of fish and buy fish from sustainable sources.

Fish Market

What Fish Can I Use In A Fish Pie?

If you are worried about bones in your fish, buy filleted fish from the supermarket, or ask the fishmonger to de-bone the fish for you.

In this Slimming World fish pie recipe, I use a fish pie mix that my supermarket sells. It contains white fish, smoked haddock, and salmon. The fish is cut up into cubes so I really don’t have to do much prep.

The beauty of a fish pie is that you can use whatever fish you prefer.

I actually turned this fish pie into a seafood pie because I used not only fish but also a seafood mix of prawns, mussels, squid, and scallops.

I thought having a mix would make for a more textured and flavourful pie – and I was right – this really was delicious!

How Can I Make A Slimming World Friendly Fish Sauce?

I used Philadelphia Light to make the sauce, which is 2 Syns per 25g (at the time of writing, please check your SW book or online for current values). You could use a flavored variety like garlic and herbs, or chives if you like as they are the same Syns count.

It’s around 16 Syns for the whole dish, but it’s 4 portions. You could make it with fewer Syns by using Extra Light Philadelphia (1.5 Syns per 25 at the time of writing), or you could make it completely free by using Quark.

This recipe for Slimming World Friendly Fish Pie serves 4 and has 4 Syns per serving when Food Optimising.

Weight Loss Trackers

A visual representation of how many pounds you have lost can be a great motivator. At SW meetings you get stickers for half-stones, and stones lost. But what if you don't attend a meeting?

Here are some products I found on Etsy that I think are fantastic, and I'm investing in a couple of them myself to help me stay focused on my journey.
