Dave isn’t a huge fan of fish – we usually eat a lot of chicken – yet he loved our first Slow Cooker Fish Pie! Amazingly, there aren’t that many slow cooker fish recipes online and a lot of people don’t really think cooking fish in a crock pot is something you can do. But, you can definitely cook fish and even seafood in the slow cooker so I thought I’d share this one and it’s turned out to be one of our favourite slow cooker recipes and one of our regular dinner ideas too.

You can cook the whole recipe in the slow cooker pot as long as you have an ovenproof slow cooker inner. After cooking the fish element and cooking your mash potatoes you then need to construct the pie and grill or oven until golden brown on top which adds slightly to the cook time.

Do I need to cook fish before making this fish pie slow cooker recipe?

This super easy slow cooker fish pie is a great meal for all the family and a real comfort food. You can include any fish you like in this mixed fish pie recipe – and you don’t need to cook it beforehand either. Smoked haddock or any smoked fish, salmon fillets, cod fish and even prawns or shrimps if you fancy them. The ingredients can be varied to suit the tastes of your whole family.

Why should I make a slow cooker fish pie?

The slow cooker fish pie is a great way of getting fish into your diet and even our young children love it. The mashed potato topping makes it the perfect one pot meal or you can add vegetables on the side if you wish or even put them in the slow cooker too – peas or sweetcorn would work wonderfully.

Alternatively, any seasonal vegetables would be a great accompaniment to this dish. The whole family love this fish pie and it’s a really healthy slow cooker meal.

What fish should I use in the slow cooker fish pie?

A slow cooker fish pie is as wholesome and full of flavour as a shepherds pie or cottage pie but is a great way of getting more fish into your diet and you can use any kind of fish depending on your favourite flavours or what fish is on offer when you’re looking to make this easy fish pie.

Is a fish pie a lot of work to make?

The sauce is the hardest part of the fish pie to make but it only takes a few minutes and then everything can be popped in the slow cooker to start the cooking process. The sauce is made just from milk, flour and butter which thickens up nicely and makes a great base for the fish pie.

If you have an oven proof slow cooker pot you can take a couple of minutes to just spoon the mash on top of the mixture once cooked, topping with the sprinkle of cheese and then continue with the rest of the recipe.

You can also make individual mini fish pies if you want too which would be fantastic to freeze in portions as baby food or for children’s meals for the little ones. It’s not quite finger food but is something the children loved when they were weaning as toddlers.

What to serve with fish pie?

When ready to serve the food, the Crock Pot Fish Pie should be lovely and golden brown on top. It’s one of those meals that is ready to eat straight away and we have also had leftovers the following day at times – just make sure you heat the leftovers fully before eating.

Fish pie is best served simply with steamed vegetables and a crack of ground black pepper. We love a selection of green veg and sometimes even sweetcorn too and frozen peas can also be thrown into the fish pie mix before baking. You could also add lemon slices on the side if you wanted.

This is quite a low fat, healthy, low calorie recipe and apparently it could be a Weight Watchers friendly or Slimming World fish pie if you’re looking for low syn or syn free recipe. I’ve never followed Slimming World or used any Slimming World recipes but I hope this helps! It’s definitely one recipe we loved when we were focusing on weight loss.

The is the best fish pie recipe we have ever used, it’s a pretty healthy fish pie too and it’s something the whole family really enjoy for dinner. It’s become one of our favourite family meals.

    • I’m sure you could as long as it hasn’t been frozen before from a health/reheating/freezing perspective. As it’s quite a creamy style sauce I’m not sure how well it will freeze – we haven’t tried it. If you try can you report back and let me know? 🙂
