  • Can I use Frozen Filets? You can use frozen cod, but it needs to be thawed in the fridge overnight before cooking.

How To Make Cajun Baked Cod

Whether you’re a seafood lover or not, this baked cod will change your mind. Even my kids, who usually run from anything fishy, gobble it up every time! Pair it with some dirty rice for the perfect combo.

  1. Whisk: Preheat the oven to 400 degrees Fahrenheit. Add the cod to a 13 x 9 x 2-inch baking dish, then season with salt and pepper to taste. In a small bowl, whisk together the melted butter, olive oil, garlic, and Cajun seasoning.
  2. Brush & Bake: Brush the sauce evenly over the filets in the baking dish, then bake uncovered for about 15 minutes or until the fish is opaque and flakes easily. Make sure it reaches an internal temperature of 130 degrees Fahrenheit. Garnish with chopped parsley and lemon slices, if desired.

Alyssa’s Pro Tip

Fork Test: Stick a fork in the thickest part of the fish and give it a little twist. If it flakes easily and looks opaque, you’re golden. If it fights back or looks see-through, it needs more time!

FAQs for Baking the Best Cod

  • Why is my cod tough? To avoid this, try using a meat thermometer or my fork test to ensure perfectly cooked, tender cod every time.
  • What is the difference between cod loin and cod fillet? A loin is considered the prime cut of the fish — it’s a thick, center portion taken from the fillet. A fillet refers to the full side of the fish, including both thick and thin parts.
  • Is salmon or cod healthier? Both are healthy options, just in different ways. Cod is leaner and lower in fat, while salmon is rich in heart-healthy omega-3s and healthy fats.
  • Can I use this method with other types of fish? Absolutely! Just stick to similar-sized cuts, use the same baking method, and make sure it reaches 130°F for that perfect, flaky finish.

How to Store Baked Cod

  • In the Fridge: Place in an airtight container and store in the refrigerator for 3 to 5 days.
  • In the Freezer: Let it cool completely before storing, then place in an airtight container or ziplock bag and store flat in the freezer for up to 1 month.
  • Reheating: Place in the oven at 350 degrees Fahrenheit for 12 to 15 minutes or gently warm in the microwave with shorter time intervals.

Make it a Meal!

If you’re looking to make it a meal, I’ve got you covered. This fish is light and fresh, so keep the sides in the same vibe — think simple salads, roasted veggies, or a quick rice pilaf.

    This recipe is absolutely delicious! I was wondering if you would be able to tell me how many weight watchers points it would be? Thank you!!

    1. I used to do weight watchers and haven’t in so long. Let me see if I am able to find it for you!

  2. 5 stars
    Wow wow wow!!!! Absolutely love this recipe. It was quick and easy but soooo delicious. I’m not normally a fan of fish but my boyfriend was craving, so I tried this recipe out and we both fell in love. Used frozen cod (thawed out during the day) and you could not even tell in the slightest. Thank you so much for an amazing recipe. Will definitely be adding this to my cook book 🙂 A++

  3. This dish is simply delicious! So easy, no fuss but tastes like it took a lot of effort. I’ll definitely be making this again!

    Sounds like a winner … making. Tonight to go with cabbage … can’t wait to try it? Threw in a few shrimp on the stone too:)

    I saw fresh looking cod at Costco. I quickly googled recipes and came across this one. I was very happy that I did. It was quick and easy to prepare and clean up. Everyone loved it including two teenagers not familiar with the fish. I will use this recipe again.

    Husband loved this! It’s now a favorite. He’s diabetic so I’m always looking for variety in tasty recipes.

  8. This looks awesome. I’m making it tonight along with the suggested green beans with bacon. I will rate tomorrow. Just a suggestion, please cut down on the ads. I’m having trouble loading the recipe and there is no way the video will load. I would love to watch, though

    1. Dani,
      I find ads annoying when looking at recipes too. My suggestion is to click the print recipe button. Most often this opens the recipe in a new tab but you don’t have to print. No ads. ?

    Made this tonight for dinner and it was not only quick and easy, but absolutely delicious as well! Adding this recipe to my collection as I’ll definitely make it again.

      I baked it with cod right out of the freezer! (I think this is a cooking faux-pas but I do it often with white fish or I’d never have time for fish dinners) The fish was moist and soft. You lose a bit of flakiness but it wasn’t rubbery. Add about 10 minutes to the cooking time, and don’t cover it, I think that would make it soggy. Delicious, easy recipe! We thought a squirt of lemon wedge was good with it too.

  10. I noticed in the picture of this recipe: BAKED CAJUN GARLIC BUTTER COD, there are lemons and parsley in the dish, but the recipe makes no mention of these?

  11. I made this last night using homemade Cajun seasoning. I sprinkled lemon juice over the cod filets and omitted the salt and pepper — I figured there was enough of that in the seasoning I had just made. It turned out to be perfect and the whole family enjoyed it. I am looking forward to making the one-pot Cajun pasta next. Thanks for a great recipe!

  12. 5 stars
    First time I made it, turned out a little too salty because I sprinkled some salt before the Cajun butter mix. Second time I made it, only sprinkled fish with black pepper and oregano before the Cajun butter and came out great! Thanks for this simple, yet delicious recipe 🙂

  13. I finally tried some of your recipes and they have been wonderful. We had lobster bisque one night so I tried your air fryer grilled cheese and yum! Last night I made the chocolate chip cookies recipe and my husband loved them! I will definitely be making more of your recipes. Keep up the good work!
