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.

  • 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.

    This fish is SO good. It is now part of my dinner rotation 🙂 It is savory and full of flavor and healthy! I made it with some steamed broccoli (which I drenched with the sauce afterwards) and we dipped our bread in it! Thank you for posting this!

  2. 4 stars
    Nice recipe! One tip people should know that most store-bought Cajun spice brands are ridiculously oversalted. If theirs has 150mg or more per serving (Some have up to 350mg!), probably best to use less, or skip the extra salt, depending on taste.

    Also, you say 130°, but literally every source I’ve ever seen says 145°for cod to be safely done.

    Made this yesterday and my partner and myself absolutely loved it, served it with mini roasties and green beans.

    My husband absolutely loves this recipe. He asks for it at least twice a week. It is easy to throw together & it has great flavor. Made it as stated except I added more garlic because we love garlic in everything.
    Thanks for sharing

    First time baking cod. It was delicious. Your recipe and instructions were followed to a T without a question about cooking time ( always a question of mine). Thank you. My husband absolutely loved it. We buy our fish fresh from Alaska…how could it be better?

    First time making cod. I skipped the initial salt and peppering since it was in the Cajun mix. Super yummy! Thank you!

  7. This recipe was great. I just love cod. It was quick and easy to prepare. I do think it was just a bit salty.

  8. 5 stars
    I had some leftover sundried tomatoes in olive oil which I substituted for just olive oil, and I added 1/4 C of half and half to give it a little more substance to serve with our side of couscous and baked green beans. It was rich and we ate about 1/2, but the base recipe was the perfect starting point. We’ve never cooked fresh cod before. Absolutely perfect! Thank you!

  9. The pictures show green herbs and lemon slices but there’s no mention of them in the ingredients 🙈😂 Is there?
    Anyway… I’ll pop those on my shopping list too before I make this one!

      1. 5 stars
        This was quick and tasty! I opted to follow the recipe for the homemade Cajun seasoning since I didn’t have any on hand and I think it made all the difference. Definitely adding this to the rotation!

  10. 5 stars
    Excellent flavor with the Cajun seasoning. Instead of using the oven I did it on top the stove in a non stick pan, on med low to low with a cover. This is a keeper.
