This is a seasonal take on the classic fish pie! Celeriac is at its best right now and makes a lovely alternative to mashed potato. For me, fish pie has to have cod, smoked haddock, and prawns in it to taste really special. I’ve used seasonal leeks, combined with dill and parsley to add comforting flavours to the creamy sauce of the pie. As kale is also seasonal right now I hope you will enjoy this as the perfect nutritious accompaniment to your pie.
