How long do you bake cod and what temperature?

No matter how you decide to prepare your fish by poaching, broiling, grilling, stewing, etc. -- make sure not to overcook it. Think 8-10 minutes per inch of thickness, i.e. if you have 2 pieces of 1-1/2 inch thickness and weighing about 16-20 ounces, do not cook it for any more than 20-30 minutes. Your oven should be set no high than 350 F or 160 C. Grilled cod fish is done once it starts to flake.
