Air-Fryer Cod Fillets: Quick, Crispy, Delicious

Air fryer cod is a quick, easy, and healthy way to cook fish, with a cooking time of under 20 minutes. It's a great option for a busy weeknight as it requires minimal prep and cleanup. The air fryer gives the cod a crispy golden crust while keeping the inside tender and flaky. This simple recipe can be made with a variety of seasonings and served in several ways, making it a versatile dish that can be tailored to your taste preferences.

Choosing the right cod fillets

When choosing cod fillets for your air fryer, there are a few things to keep in mind to ensure the best results. Firstly, it is recommended to use thicker fillets or cod loins, as they tend to be of higher quality and are less likely to dry out during the cooking process. This is especially important if you are cooking frozen cod, as thinner fillets may cook too quickly and become dry.

If you are starting with frozen cod, it is important to properly thaw it before cooking. Avoid using hot water, as this can start the cooking process and affect the final texture of the fish. Instead, place the frozen cod in the fridge overnight, or submerge it in a sealed bag of cold water for a quicker thaw.

Once your cod is thawed, it is important to pat the fillets dry with a paper towel before adding any seasoning. Removing excess moisture will help the fish brown better and result in a crispier exterior. It is also crucial to ensure that your cod fillets are of similar thickness. This will help ensure even cooking, so that some pieces are not overcooked or undercooked.

When it comes to seasoning, the possibilities are endless. You can brush the fillets with olive oil, avocado oil, or melted butter, and then add your preferred herbs and spices. Popular choices include Old Bay Seasoning, lemon pepper, Cajun spice, garlic powder, paprika, salt, and black pepper. You can also experiment with pre-made seasoning blends, such as taco seasoning.

Brushing with oil or butter

Brushing your cod fillets with oil or butter is an essential step in the air-frying process. It ensures that your cod fillets emerge with a crispy exterior and a juicy, flaky interior. The oil or butter also helps the seasoning stick to the fish, enhancing the flavour.

To brush your cod fillets with oil or butter, start by patting the fillets dry with a paper towel. This step is crucial as it removes excess moisture, allowing for better browning and a crispier texture. You can use a variety of oils, such as olive oil, avocado oil, or vegetable oil. If you prefer butter, melt a small amount, about 2 teaspoons, in a microwave or a small heatproof bowl in the air fryer.

Once your fillets are dry, use a pastry brush to coat the flesh side of the fish generously with your chosen oil or butter. Make sure to brush both sides of the fillets to ensure even coverage. If using oil, you can also brush the inside of your air fryer basket with the remaining oil to prevent sticking. This step is optional but can help ensure your cod fillets don't stick to the basket during cooking.

After brushing with oil or butter, it's time to season your cod fillets. Sprinkle your chosen seasoning or spice mix on both sides of the fillets. You can use a variety of seasonings, such as Old Bay Seasoning, Italian seasoning, garlic powder, paprika, salt, and black pepper. Get creative and experiment with different combinations to find your favourite flavour profile.

Finally, let the cod fillets sit for a few minutes to absorb the spices and herbs. This step ensures that the flavours really penetrate the fish, resulting in a more flavourful dish. Once the fillets have rested, they are ready to be placed in the air fryer and cooked to perfection.

Adding seasoning

When it comes to seasoning your cod fillets, the options are endless. You can use any herbs and spices you like to suit your taste buds.

Start by patting the fillets dry with a paper towel. This helps to remove excess moisture, allowing for better browning. Then, brush both sides of the fillets with oil or melted butter. You can use olive oil, avocado oil, or butter.

Next, it's time to add your chosen seasonings. You can use a pre-made seasoning blend, like Old Bay Seasoning, Italian seasoning, or taco seasoning. Or, create your own blend by mixing spices like garlic powder, paprika, salt, black pepper, and lemon pepper. Get creative and experiment with different combinations to find your perfect flavour profile.

After seasoning, let the cod marinate for a few minutes to absorb all the flavours. You can also sprinkle on additional seasoning after cooking for an extra punch of flavour.

Don't forget to grease the air fryer basket with oil or cooking spray before placing the seasoned cod inside. This will ensure your cod doesn't stick and helps to achieve that perfect crispy exterior.

Air-frying

Step 1: Prepare the Cod Fillets

Start by patting the cod fillets dry with a paper towel. This step is crucial to remove any excess moisture, ensuring better browning and a crispier texture. If your cod fillets are frozen, it is recommended to thaw them first. You can do this by placing them in the refrigerator overnight or submerging them in a sealed bag of cold water for a quicker method.

Step 2: Preheat the Air Fryer

Preheat your air fryer to the desired temperature. The ideal temperature for cooking cod fillets is between 350°F and 400°F (200°C). Preheating ensures even cooking and helps achieve the desired crispy texture.

Step 3: Season the Cod Fillets

Brush both sides of the cod fillets with oil, butter, or a mixture of olive oil and lemon juice. You can also add lemon zest for extra flavour. Then, season the fillets with your choice of herbs and spices. Popular options include Old Bay Seasoning, garlic powder, paprika, salt, and black pepper. You can also experiment with other seasonings like Italian seasoning, taco seasoning, or a flavoured rub.

Step 4: Air Fry the Cod Fillets

Place the seasoned cod fillets in the air fryer basket. Make sure to grease the basket with oil or cooking spray beforehand to prevent sticking. Cook the cod fillets for 8 to 10 minutes, depending on their thickness. For best results, flip the fillets halfway through the cooking time to ensure even cooking and browning on both sides.

Step 5: Check for Doneness

Use a meat thermometer to check if the cod fillets are cooked through. The internal temperature should reach 145°F (63°C) for safe consumption. If you don't have a meat thermometer, you can also check for doneness by forking the fish. The cod is cooked when it flakes easily and has a completely white or opaque colour.

Step 6: Serve and Store

Serve the air-fried cod fillets immediately for the best taste and texture. You can garnish with fresh parsley, lemon wedges, or your favourite sides. If you have any leftovers, store them in an airtight container in the refrigerator for up to three to five days. To reheat, use the air fryer at 350°F for a few minutes to regain the crispy texture.

Serving and storing

When serving air-fried cod, it is recommended to serve it immediately to enjoy its optimal taste and texture. You can serve it with a side of tartar sauce, aioli, or a zesty homemade salsa for an extra burst of flavor. It can also be served with rice, vegetables, potatoes, or salad.

For storing, place the leftovers in an airtight container and store them in the refrigerator for up to four to five days. To freeze, let the fish cool completely, then transfer it to a shallow container and store it in the freezer for up to two months.

To reheat, you can use an air fryer or a skillet. Reheat the fillets for 2-3 minutes or until heated through. It is worth noting that the crunchiness might not be the same, but it will still taste good.
