A delicious comfort food classic re-made, this fish pie still tastes every bit as good as the original but is lighter, healthier and packed full of veg. It's also got tested gluten and dairy free options that taste yummy, so no one has to miss out!
Preheat the oven to 200C/400F/gas 6. Bring a pan of water to the boil and add the peeled chopped potatoes. Simmer for 15-20 mins, until soft, adding the broccoli for the last 5 mins. Drain and set aside.
Pour the milk into a large saucepan and bring to a simmer, then add the fish, ground cloves and nutmeg. Cover with a lid and poach the fish for 5-10 mins, until cooked and easy to flake. Drain the fish, reserving the milk for later use, and flake the cooked fish into a large casserole dish, adding the prawns (you can add them straight from frozen if using them).
In a large frying pan, melt the butter (or oil) and add the finely diced vegetables. Cook over a gentle heat for 10 mins, or until the veg is nicely softened and slightly golden. Stir through the flour and cook for another minute before slowly stirring in the poaching milk. Simmer for a couple of mins until thickened, then add to the roasting dish and mix with the fish and prawns. Stir through the peas, spinach and capers, then season to taste. Mix everything well.
Mash the potatoes and broccoli (I like to blitz the broccoli with a hand blender or stick them in the food processor first so they really blend into the potatoes rather than stay a little chunky), and add the butter or oil, fresh herbs and seasoning. Mash well and layer over the fish and veg in the roasting dish. Sprinkle with the cheese, if using. Bake in the oven for 20-30 mins, until golden and bubbling. Serve hot with a side salad.
