There’s more than one way to prepare blue cod, a favorite of many and a true delicacy from the sea.
And although each method gives a unique result, all of them must respect a basic safety rule: the safe minimum internal temperature for the consumption of fish.
If you feel like you’re always winging it when it comes to preparing blue cod, whether on the stovetop, in the oven, or on the grill, you no longer need to! We’ve written this guide to help you know exactly what internal temperature to look for, and more.
Cook your blue cod to an internal temperature of 145°F (63°C). This temperature applies to all cooking methods and should be measured with a meat thermometer inserted into the thickest part of the fish.
Some bloggers, celebrity chefs, and cookbook authors may recommend lower internal temperatures for more tenderness. Although the decision is ultimately yours, keep in mind that you’re taking a risk by doing so, as bacteria, parasites, and viruses in undercooked blue cod can make you sick.
Also, do not forget that by cooking blue cod for the members of your household, you’re very often taking that decision for them. If you’re preparing blue cod for the young, the pregnant, the elderly, and those with a compromised immune system, cook it thoroughly to keep the risk of foodborne illness to an absolute minimum.
What About the Time in the Recipe?
Cooking times given in recipes are only approximate, and you should treat them as such.
The exact cooking time for blue cod, whole or filleted, comes down to its size, the appliance you cook it on, the cooking vessel you prepare it in, the method of cooking, as well as the amount of heat used.
These factors, as you have probably already thought to yourself, vary greatly from home kitchen to home kitchen and from cook to cook. The only way to reliably tell if blue cod is done is to check it early and check it often.
Now you know how, and what internal temperature to look for!
The Best Ways to Cook Blue Cod
Blue cod is best prepared in three ways: under the broiler, in the pan, and on the grill.
Broiling blue cod: To broil blue cod, heat your broiler for 15 to 30 minutes. Just before cooking, take the blue cod out of the refrigerator, season it generously with salt, place it on a greased sheet pan and slide it under the broiler. Check for doneness after 2-3 minutes.
Pan-frying blue cod: To pan-fry blue cod, pull out a cast iron skillet or non-stick pan, add a big dollop or two of cooking oil, and heat over medium heat. Salt the blue cod liberally and fry. Check for doneness when it’s golden brown on both sides.
Grilling blue cod: For charcoal grills, light the coals and wait 20 minutes. For gas grills, light the burners and heat on medium for 15 minutes.
Season the blue cod, place it on a tray greased with cooking oil and let it cook on the grill with the lid closed. Check for doneness when it has turned a golden brown color.
Blue cod pairs deliciously well with.
Can You Undercook Blue Cod?
Blue cod can indeed be undercooked. And when it is, eating it can lead to food poisoning or a parasite infection. Take caution to cook your blue cod to the safe minimum internal temperature for consumption.
A lot of home cooks and their households enjoy eating lightly cooked blue cod. But blue cod, high in moisture and rich in proteins, can harbor disease-causing bacteria and harmful parasites of the sea if undercooked.
In particular, raw or undercooked blue cod may be contaminated with Salmonella, a pathogenic bacterium that causes a serious disease called salmonellosis, as well as a number of parasites, called “worms,” known to infect fish.
Can You Overcook Blue Cod?
Like all other fish and creatures of the sea, blue cod overcooks quickly.
Overcooked blue cod is dry, tough, and rubbery, and is often left uneaten. Sure, you can always give it a makeover by adding it to a soup or stew—but then there’s little point in baking, broiling, grilling, or pan-frying it in the first place.
Remove the blue cod from the heat as soon as it reaches an internal temperature of 145°F (63°C). If you don’t trust yourself to keep the blue cod from overcooking, braise or poach it.
Both of these cooking methods rely on moist heat, and so they’re more forgiving of mistakes and haste.
Blue cod should be cooked to a minimum internal temperature of 145°F (63°C), regardless of the cooking method. Broil it, pan-fry it, or cook it on the grill, and be sure that you neither under- or overcook it.
