Fish pie recipe with a crispy seed topping

Crispy seed topped fish pie recipe

There’s something about a classic fish pie recipe that appeals to the cosy loving part of me and it’s one of the first recipes I learnt when stepping out into the Big Wide World. Over the years I have altered it and chopped and changed some ingredients but the most recent version I topped with seeds and we were all really pleased with the results.

The seeds add texture and flavour to the topping not to mention important nutrients.

This fish pie follows the classical basic recipe but then I added a few ingredients to make it even more special and I’d love to know your thoughts, here’s what the mixture looks like prior to adding the mash

    I love your recipes Mari – this looks particularly fab. I can’t eat fish but make a pie for the boys and students sometimes because it’s just so good for them all. I like the beans and spinach adds-they make a change from the carrots and broccolli I shove in ours! :)
