First of all......find yourself one of these babies

4 thick, skinless fillets, about 140g each
50g fresh white breadcrumbs
finely grated zest of 1 lemon
25g Parmesan, freshly grated
1-2 thyme sprigs, leaves stripped
sea salt and black pepper
1-2 tbsp olive oil
lemon wedges, to serve
 
Heat the oven to 220C.
Place fillets, skinned side up, on a lightly oiled baking tray.
In a bowl, mix together the breadcrumbs, lemon zest, Parmesan, thyme and a little salt and pepper to taste, Stir in a little olive oil to combine.
Spread the breadcrumb mixture evenly on top of each fish fillet.  

Bake in the oven for between 7 minutes and 12 mins (depends on the thickness of the fish) The topping should be golden brown and crisp and the fish flesh is opaque - you will be able to push a fork through without any resistance......MMmmmmm
Pretty yum on Cods as well....actually, probably pretty good on most fish :)
