Slow Cooker Fish Pie Recipe

Hubby isn’t a huge fan of fish – we usually eat a lot of chicken – yet he loved this 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 slow cooker 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. It’s a great meal for all the family and you can include any fish you like – smoked haddock, salmon and even prawns 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?

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.

When ready to serve the food, the Slow Cooker 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.

The is the best fish pie recipe we have ever used and it’s something the whole family really enjoy. If you’re looking for weaning recipes then this would be a great easy fish pie recipe for babies, toddlers and beyond.

    I would never of thought to cook fish pie in a slow cooker but this looks delicious. Infact I need to dust off my slow cooker and start using it again x

    Are you able to freeze if the fish I use is chilled and not frozen? Wondered if I could make a batch?

      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? 🙂
