Cooking frozen cod fillets in an air fryer is a quick and easy way to get a delicious, healthy meal on the table in under 20 minutes. There are a few different ways to cook frozen cod fillets in an air fryer, depending on your desired level of crispiness and flakiness. Some recipes recommend thawing the cod fillets first, while others suggest cooking them straight from frozen for extra convenience.

Preheat the air fryer

Preheating your air fryer is an important step in the cooking process, as it ensures your cod fillet cooks evenly and efficiently. The ideal temperature to preheat your air fryer to is 400°F (200°C).

Firstly, remove the cod from its packaging and place it on a plate. Drizzle olive oil over the cod fillet and rub it into all surfaces. This will ensure the fish doesn't stick to the air fryer basket and helps to create a crispy exterior.

Next, season the cod fillet. You can use salt and pepper, and dried herbs such as oregano or parsley. You can also try garlic powder, paprika, or lemon pepper. Leave the cod to marinate for 5 minutes so it can absorb the herbs and spices.

While the cod is marinating, preheat your air fryer to 400°F for 5 minutes. This is the optimal temperature for cooking frozen cod, as it will ensure the exterior is crispy and the interior is tender.

Once the air fryer has preheated, you can place the cod fillet inside and begin cooking. It's important to note that the cooking time will depend on the thickness of your cod fillet. For a thicker fillet, you may need to increase the cooking time to ensure the fish is cooked through.

Pat the cod fillets dry

If you have time, it is recommended to thaw your frozen cod before cooking. You can do this by placing the cod in the fridge overnight or submerging it in a sealed bag of cold water. However, if you are short on time, it is safe to cook the cod straight from the freezer, as long as you ensure it reaches an internal temperature of 145°F, or 63°C, to avoid any bacterial growth.

Once your cod fillets are thawed and patted dry, you can proceed to season them with your desired herbs and spices. Some popular options include salt, pepper, paprika, garlic powder, and dried oregano or parsley. You can also experiment with different seasonings like Old Bay, lemon pepper, or cajun spice to find your favorite flavor combinations.

After seasoning, it is crucial to preheat your air fryer to ensure even cooking. Most recipes recommend preheating to temperatures between 350°F and 400°F for about 5 minutes. This step helps to create a crispy exterior on your cod fillets.

By patting your cod fillets dry, you are setting yourself up for success in achieving well-browned, crispy, and flavorful air-fried cod.

Season the fillets

Seasoning the cod fillets is a crucial step in the cooking process, as it adds flavour and helps to create a crispy exterior. The type of seasoning you use is entirely up to your preference, but here are some suggestions:

Firstly, you can pat the cod fillets dry with a paper towel. This step helps to remove excess moisture, which can interfere with the browning process. Then, brush both sides of the fillets with oil or melted butter. You can use olive oil, avocado oil, or any other cooking oil of your choice. Make sure to get a good coat on both sides, as this will help the seasonings stick to the fish and create a crispy exterior.

Next, it's time to add your chosen seasonings. You can use a variety of herbs and spices, such as garlic powder, paprika, salt, and black pepper. You can also use pre-made seasoning blends, such as Old Bay Seasoning, lemon pepper, or cajun spice. If you want to keep it simple, just salt and pepper will do. Be sure to sprinkle or rub the seasonings generously onto all surfaces of the cod fillets.

If you have time, you can let the cod fillets marinate in the refrigerator for a few minutes to absorb the spices and herbs. This will give your fillets a more intense flavour. In the meantime, you can preheat your air fryer to the desired temperature, usually between 350-400 degrees Fahrenheit.

Once your cod fillets are seasoned and your air fryer is preheated, you're ready to place the fillets in the air fryer basket and begin cooking. Depending on the thickness of your fillets and the temperature of your air fryer, they should cook for around 8-20 minutes. Be sure to flip the fillets halfway through the cooking process to promote even cooking and browning.

Cook at 350°F for 8 minutes

To cook frozen cod fillet in an air fryer, start by preheating your air fryer to 350°F. It is important to ensure that your air fryer is preheated to the correct temperature before you put your cod fillet in. This will ensure that your cod cooks evenly and efficiently.

Next, you'll want to prepare your cod fillet. If your cod is wrapped in plastic, be sure to remove this first. It is also recommended to pat your cod fillet dry with a paper towel before seasoning. This will help to remove any excess moisture, which will, in turn, help with the browning of your cod.

Now, it's time to season your cod fillet. Brush each side of the fillet with olive oil and lemon juice. You can also add your own choice of seasonings to each side of the fish. Try a blend of herbs and spices, such as garlic powder, paprika, salt, and pepper, or dried parsley. Alternatively, you could make a lemon and butter emulsion to drizzle over the top.

Once your cod fillet is prepared, place it in the air fryer basket and cook for 8 minutes at 350°F. It is important to note that the cooking time may vary depending on the thickness of your cod fillet. For this reason, it is recommended to use a meat thermometer to check that your cod has reached an internal temperature of 145°F. This will ensure that your cod is cooked safely and thoroughly.

After 8 minutes, or when your cod has reached 145°F, it should be ready to serve. It should be golden brown and crispy on the outside, with a soft and flaky middle. Serve with a squeeze of fresh lemon juice, or a dipping sauce such as tartar sauce or avocado cilantro sauce. Enjoy!
