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! The best part, it’s on your table in minutes!

  1. Whisk: Preheat the oven to 400 degrees Fahrenheit. Addย the codย to a 13 x 9 x 2-inch baking dish, then season withย salt and pepperย to taste. In a small bowl, whisk together the melted butter,ย 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, youโ€™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 โ€” itโ€™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 130ยฐF for that perfect, flaky finish.

How to Store Baked Cod

  • In the Fridge:ย 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 โ€” think simple salads, roasted veggies, or a quick rice pilaf.

    It was delicious!!! Added asparagus and jasmine rice as my sides!! We will be having this again and Iโ€™m making sure to share it with friends!! Super easy day of the week meal!!

  2. 5 stars
    Wow! This was so good and so quick and easy. I donโ€™t understand how anyone could call it bland if they made it per recipe. Must have old seasoning.

  3. This was really good! I think people saying it was bland maybe were not using a good Cajun seasoning. Like one person who commented serving it with rice, I did the same with rice pilaf.Thanks!!

    1. Hi, thank you for commenting. I am not sure why this didn’t have enough flavor for you. Garlic and cajun seasoning are typically very flavorful. You can always add ore seasoning, or salt and pepper to help if you feel it is lacking in flavor. I am sorry this dish didn’t meet your expectations.

  4. 5 stars
    Hardly any preparation required. A quick dish with a good deal of spice. We will have this again.

    This was ok not great. Too much butter/oil made it greasy. Needed more Cajun seasoning. I will stick with recipes that call for coating the fish.
