  1. Preheat the oven to 190˚C/170˚C/gas 5. Put the milk and bay leaves into a large lidded saucepan or deep frying pan and heat until steaming and just beginning to bubble. Add the fish, put the lid on and turn the heat off for 4 mins. Carefully lift the fish onto a plate and reserve the poaching liquid (discard the bay leaves). Remove the skin from the haddock and roughly flake the fish into large chunks.
  2. In another large frying pan, heat 1 tbsp of oil and cook the shallots over a medium heat for 10-12 mins until golden. Add the garlic for 1 min. Stir in the flour for another 2 mins, stirring constantly, then add the milk little by little and stir for 3-4 mins until thick enough to coat the back of a spoon. Add the zest, parsley and half the cheese and stir until melted, then add the fish, and spoon into a 2-litre baking dish.
  3. Toss the breadcrumbs with the remaining tbsp of oil and scatter over the top, then scatter over the remaining cheese. Bake for 25-30 mins until golden and bubbling then serve with a scattering of parsley.
