Grilled Cod

Cod has a very mild flavor, making it a great candidate for grilling with blackened seasoning. I don’t like to mess with my fish too much, so giving it a good seasoning and searing it on the grill allows the flavor of the fish to really shine through.

Blackened cod is such a tasty and tender bite of flavorful white fish. Cod is one of my favorite fish to grill because the flavor is inherently buttery and the char from a hot grill makes for the perfect flavor companion. An added bonus and argument for grilling is that the savory and spicy blackened seasoning gets smoky when cooked inside. Outdoors is the perfect place to cook up this grilled cod!

Blackened Seasoning for Grilled Cod

With cod being such a mild-flavored fish, I just knew it would cook wonderfully with blackened seasoning. This seasoning was a huge hit with my recipe for Grilled Mahi Mahi, and it did not disappoint on the cod either.

My recipe for blackened seasoning combined smoked paprika and eight wonderfully balanced herbs and spices to bring plenty of flavor with a little heat as well.

I love this blackened seasoning so much, I wrote an entire post about it. If you want more information on making and storing this seasoning, check out the full write-up by clicking this link for The Best Blackened Seasoning.

How to Grill Cod

We’ve already established that cod is super tasty cooked on the grill (and even better when blackened), so let’s talk about how to get this fish cooked to perfection. Grilling cod is as easy as 1-2-3! Simply season, sear, and grill!

  1. Season. Combine all ingredients for the blackened seasoning in a bowl. You can get the full recipe in the recipe card below or head to the post for Blackened Seasoning for more information on making this awesome blend. Any unused seasoning can be stored in an airtight container for a few weeks. Liberally season all sides of the cod with the blackened seasoining.
  2. Sear. Preheat the grill to 400 degrees F, then place a 12-inch cast-iron skillet on the grill to preheat. Once the skillet is hot, add avocado oil then the seasoned cod (seasoned side down) to the skillet once the oil starts to smoke. Sear for 3-4 minutes.
  3. Grill. Turn down the heat in the grill to 350 degrees F. Flip the cod over, and continue cooking for another 10-12 minutes or until the internal temp of the fish reaches 145 degrees F.

Once your fish is fully cooked, remove it to a serving dish and serve immediately. This fish is pretty much ready to go, but you can always add a squeeze of fresh citrus if you desire.

How Long to Grill Cod

It will take approximately 15 minutes to cook a cod fillet that is around 1.5 inches thick. 

As you likely know by now, each piece of meat or fish will cook just a bit differently, so you should always cook to temperature and not to time. Cod fillets are not always perfectly consistent in thickness, so I highly recommend taking the temperature of each fillet, and removing them from the heat when they reach an internal temperature of 145 degrees F.

Thicker pieces of cod will take slightly longer to cook, so give them as much time as needed to reach doneness. You definitely don’t want to be serving or eating undercooked fish!

  • 4 cod fillets at least 1.5 inches thick
  • 3 Tablespoons avocado oil

Blackened Seasoning

  • 1 Tablespoon smoked paprika
  • 2 teaspoons salt
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon cayenne pepper
  • ¾ teaspoon fresh ground white pepper
  • ¾ teaspoon fresh ground black pepper
  • ½ teaspoon dried thyme leaves
  • ½ teaspoon dried oregano leaves


  • Preheat. Preheat your grill to 400 degrees F.
  • Make the seasoning. Combine all ingredients for the blackening seasoning in a small bowl. Liberally season all sides of the cod fillets.
  • Sear the cod. Place a 12-inch large skillet (preferable cast iron) on the grill grates to preheat. Drizzle in the avocado oil. When the oil just starts to ripple and smoke, place the cod fillets seasoning side down in the skillet. Sear for 3-4 minutes or until a beautiful crust has developed on the seasoning.
  • Finish cooking. Flip the fillets over, turn the heat down on the grill to 350 degrees F and close the lid of the grill. Cook for an additional 10-12 minutes, or until the internal temperature of the fish reaches 145 degrees F and flakes easily with a fork. If your fillets are really thin, they will cook faster, if they are thick, they will take a little longer. Use a thermometer to track your internal temperature so you don’t end up with over- or undercooked fish.
  • Serve. Remove the cod from the grill to a serving dish. Serve immediately.
