Ingredients

4 cod fillets, about 6 ounces each

2 tablespoons olive oil or avocado oil

1 teaspoon paprika

1 teaspoon smoked paprika

1 teaspoon garlic powder

1 teaspoon onion powder

1 teaspoon dried thyme

1 teaspoon dried oregano

½ teaspoon cayenne pepper, or more if desired

½ teaspoon black pepper

1 teaspoon kosher salt

½ teaspoon ground cumin

¼ teaspoon white pepper

½ teaspoon brown sugar, optional for balance

Choosing the Best Cod

Fresh cod should have a clean, mild smell with firm flesh.

Frozen cod works wonderfully as long as it is completely thawed before cooking.

Pat the fish completely dry with paper towels before seasoning. Removing excess moisture helps create the perfect crust.

Choose fillets that are similar in thickness so they cook evenly.

Homemade Blackened Seasoning

A homemade seasoning blend offers better flavor than many store-bought versions.

Mix together:

Paprika

Smoked paprika

Garlic powder

Onion powder

Dried thyme

Dried oregano

Kosher salt

Black pepper

White pepper

Ground cumin

Cayenne pepper

Brown sugar if using

Stir until everything is evenly combined.

Any extra seasoning can be stored in an airtight container for several months.

Preparing the Cod

Remove the cod from the refrigerator about 15 minutes before cooking.

Pat each fillet completely dry.

Brush both sides lightly with olive oil.

Sprinkle the blackened seasoning generously over every surface of the fish.

Press the seasoning gently into the fillets so it adheres well.

Allow the seasoned fish to rest for 5 to 10 minutes before air frying. This helps the spices stick better and improves the flavor.

Preparing the Air Fryer

Preheat the air fryer to 400°F (200°C) for about 3 to 5 minutes.

A preheated air fryer gives the fish a more even crust and shorter cooking time.

Lightly spray the air fryer basket with cooking spray if desired to reduce sticking.

How to Cook Air Fryer Blackened Cod

Arrange the seasoned cod fillets in a single layer inside the basket.

Leave a little space between each piece for proper air circulation.

Do not overcrowd the basket.

Cook at 400°F (200°C) for 8 to 10 minutes.

The exact cooking time depends on the thickness of the fillets.

Thicker pieces may require an additional 1 to 2 minutes.

The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Unlike many meats, cod usually does not need to be flipped during cooking because the circulating hot air cooks it evenly.

How to Know When the Fish Is Perfectly Cooked

The flesh changes from translucent to opaque.

A fork slides easily into the fish.

The fillets separate into moist flakes.

The edges begin to lightly brown.

The seasoning develops a beautiful dark crust.

The fish remains moist rather than dry.

Optional Garlic Lemon Butter

For extra richness, prepare a quick butter sauce.

Melt 3 tablespoons butter.

Add 2 minced garlic cloves.

Cook for about one minute.

Stir in one tablespoon fresh lemon juice.

Mix in a little chopped parsley.

Brush the warm butter over the cooked cod immediately before serving.
