It’s an ideal choice for anyone seeking a quick, nutritious, and delicious meal without the hassle of extensive prep work or complex cooking techniques. The air fryer excels at cooking fish from frozen, creating a wonderfully crisp exterior and a tender, flaky interior that rivals oven-baked or pan-fried methods, but with far less oil.

The Health Benefits of Cod

Cod is a fantastic white fish, celebrated for its delicate flavor and lean protein content. Unlike fattier fish such as salmon or sardines, cod has a much milder taste, making it a popular choice for even the pickiest eaters in your family. While it contains slightly less omega-3 fatty acids than oily fish, cod is still an excellent source of essential nutrients, including B vitamins, phosphorus, and selenium. Incorporating cod into your diet is a great way to boost your seafood intake, especially given that many of us in the U.S. don’t meet recommended fish consumption guidelines.

This recipe transforms frozen cod fillets in the air fryer into a culinary delight that’s not only good for you but also incredibly satisfying. It’s a cornerstone in my own dinner rotation, and I’m confident it will become a beloved everyday meal for your family too. Its simplicity makes it perfect for novice cooks, ensuring a successful and delicious outcome every time.

To effortlessly air fry frozen cod fillets, gather these simple ingredients:

• Frozen Cod Fillets: Two pieces, each weighing 4-5 ounces (113-142 grams). Look for fillets that are approximately ½-inch (1.27 cm) thick for optimal and even cooking. This is crucial for preventing the fish from drying out.
• Cooking Spray: A light coating of olive oil spray or your preferred cooking oil spray helps prevent sticking and promotes a beautifully browned exterior.
• Cod Seasoning: ¼-½ teaspoon. This is optional, but highly recommended. Classic choices include Old Bay seasoning, simple salt and black pepper, or get creative with your favorite fish spice blend (e.g., lemon pepper, garlic powder, paprika, dill, or a Mediterranean herb mix).

Choosing the Right Cod for Air Frying

The success of this recipe largely depends on the thickness of your cod fillets. Aim for pieces that are consistently ½-inch (1.27 cm) thick. Avoid fillets with significantly thicker middles and thin edges, as this can lead to uneven cooking—the thinner parts will dry out before the thicker sections are fully cooked. If your fish pieces are too thick (e.g., 1-inch/2.54 cm or more), they are likely to become dry before reaching the safe internal temperature. Cod loins, often cut from the thickest part of the fillet, might be too dense for this specific cooking method.

For convenience, individually packaged cod fillets are ideal as they won’t stick together when frozen. However, if your cod is frozen in a block, don’t worry—the initial air frying step will help separate the pieces. If you have fresh cod that you won’t be cooking immediately, consider freezing it in a single, non-touching layer. This prevents them from sticking and makes them perfect for this recipe.

You can also create smaller frozen cod bites in the air fryer. Just remember that smaller pieces will require a shorter cooking time, so adjust accordingly and keep a close eye on them to prevent overcooking.

Air Fryer Compatibility

This recipe works wonderfully with most air fryer models, including popular brands like Ninja Foodi, Philips, Cosori, Instant Vortex, Cuisinart, Pampered Chef Air Fryer, Actifry, Nuwave, and Power Air Fryer. However, cooking times can vary slightly between different air fryer brands and models due to differences in heating elements and air circulation. It’s always a good idea to monitor your fish and adjust the cooking time as needed, especially the first time you try the recipe with your specific air fryer.

Prepare Your Cod for Air Frying

Carefully place your frozen cod pieces in a single layer in your air fryer basket or on the tray. It’s important not to overcrowd the air fryer, as this can hinder air circulation and lead to uneven cooking. Do not rinse the frozen fish fillets; doing so can make them waterlogged and affect their texture. If you’re using an air fryer oven, position the tray on the top rack for best results.

Initial Thaw and Separation

If your cod pieces are slightly stuck together at the edges, don’t worry—this first step will take care of it. Air fry the frozen cod for 4 minutes at 350°F (175°C). This initial, lower-temperature phase is designed to gently thaw the fish, allowing the fillets to separate easily and preparing them for seasoning.

How long does frozen cod take in air fryer? What temperature for frozen cod in an air fryer? The optimal cooking strategy for air fryer frozen cod involves a two-stage approach. Start by air frying for 4 minutes at 350°F (175°C) to partially thaw the fish. Then, increase the temperature to 375°F (190°C) and continue air frying for an additional 8-15 minutes, flipping the fillets halfway through this second cooking phase. This ensures the cod cooks thoroughly without drying out.

Unlike oilier fish like salmon, cod can become dry and overcooked very quickly due to its lean nature. Our two-stage temperature method is designed to prevent this. The initial 350°F (175°C) phase gently thaws the fish, making it easier for the cooking oil and seasoning to adhere. The subsequent 375°F (190°C) phase then cooks the cod to a perfect flaky tenderness. Always use a meat thermometer to confirm the internal temperature reaches 145°F (63°C) for food safety and optimal texture.
