What Temperature should Cod be Cooked at:

Any cooking method that is used for making cod, it will be done when it reaches an internal temperature of 130 degrees Fahrenheit. It is best to use a meat thermometer for the most accurate internal temperature. Once cod reaches the proper cooking temperature the color of the fish will become opaque and flakey. If you do not have a meat thermometer by looking at the cods color can help.

The Recipe Critic Pro Tip:

Stick a fork in the thickest part of the fish and gently twist the fork at a 45 degree angle. If the fish comes along with the fork and has flaky, opaque color to it, it has reached its cooking temperature. Undercooked fish will not be translucent and it will resist flaking. 

Is Baked Cod Healthy?

Yes! That is what I love about cod and most fish recipes. Cod is nutritious with a lot of hidden flavor. It is known to have lean protein, vitamins and minerals. This is perfect to eat while maintaining a healthy diet.

A nice fruit salad with loads of colors, a side salad and many vegetable sides are all great ways to complete this meal. This cod recipe is perfect for a lighter meal but also can add in mashed potatoes or skillet potatoes to make it more filling.

FAQs for Baking the Best Cod:

  • Why is my cod tough? This usually entails that your cod was overcooked during the baking process. To avoid this, try using a meat thermometer or my fork test to ensure the best cooked cod.
  • Can you eat undercooked Cod? It is best to have a cooked fish to avoid any parasites in your body.
  • Should I cover fish in the oven? You do not need to cover the fish while it is being cooked.
  • What is the difference between cod loin and cod fillet? A loin is the prime cut of the fish. It is a section cut from the fillet. A fillet is the entire part of the fish.
  • Is salmon or cod healthier? Both fish are known to be healthy just in different ways. They do hold many nutrients, vitamins and are both a lean meat.

  1. Can you use different spices other than the Cajun? I’m quite the spice wimp. LOL
    It looks fantastic but I worry I wouldn’t enjoy it if it were too spicy.
    On another note, I have tried & enjoyed MANY other recipes from your site. Thank you. You have changed dinner from same old, same old to better & honestly restaurant quality.

    Hi there – Well I am going to give this a try in my Air Fryer. And, I am going to change the seasoning to Italian Seasoning because that is what I have on hand. Will give you an update on how it came out. Thanks for sharing this recipe.

  3. 5 stars
    Great recipe for cod! Only note: if you use ‘homemade (or store bought) Cajun spice, watch the salt intake. My homemade Cajun spice (from a recipe on Google) had salt in it. You may want to adjust the amount of salt on the cod fillets to little or none! I used unsalted butter as well. I accompanied my cod with parmesan garlic (& breadcrumbs) broccoli florets & rice!

    1. Butter and oil aren’t unhealthy in moderation and it doesn’t take anything away from the vitamin and nutrient density of the fish.

  4. 5 stars
    I should have taken a picture! This was truly superb fish. When you want a quick delicious and impressive meal this should be your centerpiece.

    We had a baked potato and mushrooms sautéed in ghee and garlic with asparagus on top and citrus infused balsamic drizzled over..

    I love the flavor and for the first time my kids ate it all without arguing…
    I have tilapia and I’m making the same recipe… i hope it taste the same!

  7. Absoluteloy Delicious! Used tinfoil on a barbeque and cooked on high for 10 min. Thanks for sharing a great recipe!

  8. 5 stars
    I made this recipe and placed on lettuce wraps and they were delicious! My husband loves them and so did my 2 picky toddlers! Definitely will be saving this to make again. I’m not a big spicy fan so I just added 1/2tbsp instead of the whole tbsp and they were the perfect amount of spice.

  9. 5 stars
    OMG! This is so delicious! I baked the cod over very thinly sliced zucchini rounds! Happy happy mouth! Thank you!

  10. 5 stars
    It was so Tasty and flaky! I didn’t stray from the recipe and it turned out. Nice amount of taste too. Thank you!

  11. Fantastic recipe! If you’re not sure how to cook card this is the recipe for you. Very flavorful so easy to make it’s almost full proof. I served it with asparagus and mushroom risotto. Unbelievable five star.

  12. I am cooking this tonight. I have put slices of lemon and lime under the fish and serving with smashed new potatoes with parmesan, and a salad of pea shoots, purple radish,courgette strips marinated in lemon and a little salt, garlic chives, baby broad beans and feta with a vinaigrette dressing. Both my husband and I cannot wait to try it, it looks and smells delicious. Thank you

  13. 4 stars
    I don’t eat cod anymore (never comes out moist or with flavor), but tried this with my fave fish Barramundi. It turned out great! Definitely a staple now.

  14. Second time making this dish but this time I added a little more Cajun spice and pilaf rice and a nice salad on the side! Mmmm good.

  15. 4 stars
    I unfortunately oversalted my fish, and my store bought cajun seasoning had salt in it also. So it was practically inedible. BUT that is my fault. The butter sauce smelled amazing on its own. I will try this again but I don’t think I will salt the fish at all.
