The Key to Making Sure Cod is Fully Cooked
The key to making sure cod is fully cooked is investing in a meat thermometer to check internal doneness. This takes all the guesswork out of ensuring that the fish is safe to eat, while also preventing you from overcooking it. If you need a good recommendation, try out the Thermapen MK4. I’ve been using it for years to help me make everything from fish to Thanksgiving turkey to smoked beef brisket.
Did you know? The safe internal temperature for cod is 145°F. Pull it out of the oven once it reaches this temperature and it’s sure to be flakey and moist.

3 Tips to Prevent Rubbery Cod
Here you’ll find 3 top tips to help you prevent your cod from turning rubbery and tough. All-too-often, this fish is overcooked and given a bad rep. Follow these simple instructions and you’ll be golden.
- Pat the cod completely dry after cleaning it. If you leave any water on the cod after rinsing it, it will boil in the oven and cause the top of the cod to overcook. Diligently pat the fish dry of any excess moisture and you’ll be good to go!
- Cook the cod with fresh lemons. As the cod bakes, the lemons will release juices that keep the fillets hydrated. A notoriously finicky fish, cod needs as much moisture as it can get in the hot oven.
- Cook the cod at a high temperature. The less amount of time the cod spends in the oven, the less likely it is to turn out rubbery and dry. That is to say, cooking it at a high temperature is key to not making it rubbery.

Best Ways to Store Your Cod Leftovers
Whether you have a few leftover fillets you plan to eat throughout the week or a batch you’d like to freeze, here are the best ways to store oven-baked cod.
- Refrigerator: To keep cod on hand for 3-4 days, store it in an airtight container in the fridge. This will keep it from drying out. Above all, it will keep your fridge from smelling fishy.
- Freezer: To freeze oven-baked cod fillets, first allow them to cool down completely. Then, wrap each individual fillet tightly in plastic wrap. Finally, place the wrapped fillets in a freezer-safe bag and store them for up to a month. To thaw, place the fillets in the fridge for a couple of hours.
Reheating Tip: The best way to reheat cod is in the microwave or oven with a couple of extra spritzes of lemon juice and a little more butter. If you have an air fryer, you can also use for reheating (‘m obsessed with the COSORI air fryer right now).

There are several different ways you can prepare the best cod. It can be baked, grilled, deep-fried, or pan-fried.
How much time does cod take to cook?
It takes about 15 minutes to bake cod in the oven at 425°F. You’ll know it’s fully cooked when the internal temperature reads 145°F, the flesh turns opaque, and it easily flakes with a fork.
Should white fish be cooked at a high temperature?
Yes, white fish should be cooked at a high temperature. You’ll want to refrain from slow-cooking white fish at a lower temperature, as it’s prone to drying out.
Does cod need to be fully cooked to be safe to eat?

Why did my cod come out so tough?
Your cod likely came out tough because it was overcooked. A general rule of thumb is cod should be cooked for 10 minutes per inch of thickness. Most fillets are about an inch-and-a-half thick, so test the internal temperature at the 15-minute mark to see if it needs additional time in the oven.
