Air Fryer Frozen Fish: How Long Does It Take?

Cooking frozen fish in an air fryer is a quick and convenient way to prepare a healthy meal. The cooking time will depend on the type of fish, the thickness of the fillets, and the specific model of your air fryer. On average, it takes between 10 to 20 minutes to cook frozen fish in an air fryer, with some recipes suggesting a cooking time of 12 to 15 minutes. It is recommended to preheat the air fryer before adding the fish, and to flip the fillets halfway through the cooking process to ensure even cooking.

Preheat the air fryer

Preheating your air fryer is a crucial step in achieving that desirable crispy exterior on your fish. It ensures your fish cooks evenly, so it's well worth the wait. Here are some tips to help you master this important step:

Preheating Time

Preheat your air fryer for about 3 to 5 minutes before adding your fish. This will ensure the appliance has reached the desired temperature, and your fish will start cooking immediately upon entering the basket.

Temperature Settings

When preheating your air fryer, the temperature you set will depend on the model of your appliance and the type of fish you're preparing. A temperature range of 350-400°F (177-204°C) is recommended for most frozen fish fillets. For thicker fillets or those with a hearty breading, consider using a higher temperature within this range.

Air Fryer Compatibility

To ensure even cooking and optimal results, choose fillets that are uniform in thickness and size. This consistency allows for even heat distribution and helps achieve that all-around crispiness.

Arranging the Fish

Once your air fryer is preheated, it's time to arrange the fish fillets. Place them in a single layer with enough space between each piece to allow for proper air circulation. This spacing is crucial for achieving an even cook and the desired crispiness on all sides of the fillets.

Visual Cues

As your air fryer reaches the desired temperature, keep an eye on it. You'll know it's ready when the preheat light goes off or when it reaches the set temperature, depending on your model.

By following these tips, you'll be well on your way to perfectly cooked, crispy fish every time!

Oil the air fryer basket

Oiling the air fryer basket is not always necessary when cooking frozen fish. Some sources say that the hot circulating air will make the fish crispy without the need for oil. However, if you want to ensure your fish doesn't stick to the basket, or if you want it to be extra crispy, you can add a light spray of olive oil or cooking spray.

If you don't want to use oil, there are alternatives to prevent your fish from sticking to the basket. You can line the basket with aluminium foil or parchment paper, poking a few holes in the foil or paper to allow the hot air to circulate. You can also use perforated parchment paper or silicone mats, which are designed to allow hot air to cook the food evenly while preventing sticking.

If you are using oil, avocado oil is recommended due to its high smoke point. Olive oil, vegetable oil, or cooking spray can also be used.

Arrange the fish fillets

Now that your air fryer is preheated, it's time to arrange the fish fillets. Place them in a single layer with enough space between each piece to allow for proper air circulation. This spacing is key to achieving an even cook and the desired crispiness on all sides of the fillets.

If you are cooking multiple fillets, make sure they are evenly spread out and in one layer. This ensures that the hot circulating air reaches all the pieces, cooking them evenly. If your air fryer basket is not big enough, you may need to cook the fish in multiple batches.

When placing the fish fillets in the air fryer, be careful not to overcrowd the basket. This will prevent the fish from crisping up and achieving that desirable golden colour. Leave a little bit of space between each fillet to allow the hot air to circulate properly.

If your fish fillets are frozen, there is no need to defrost them first. Simply coat them with a thin layer of olive oil and then with your chosen breading or seasoning. The oil will help the breading stick to the fish and also promote crispiness.

Once your fillets are arranged in the air fryer, it's time to start cooking! Depending on the thickness and type of fish, the cooking time will vary. For example, thin tilapia fillets may cook faster than thicker cuts of cod or halibut. As a general rule, the cooking time for non-breaded fillets can range from 12 to 15 minutes, while breaded fillets may need a few extra minutes.

Flip the fillets halfway

Flipping the fillets halfway through the cooking process is an important step to ensure even cooking and achieve the desired texture. Here's a detailed guide on flipping frozen fish fillets in an air fryer:

By flipping the fillets, you ensure that both sides receive equal exposure to the heat, promoting even cooking. This simple step makes a significant difference in the texture and doneness of your fish, resulting in a crispy exterior and juicy interior.

When to Flip the Fillets

The ideal time to flip your frozen fish fillets is at the halfway mark of the cooking process. For example, if the total cooking time is 12 to 15 minutes, you should flip the fillets after approximately 6 to 7.5 minutes. This ensures that both sides of the fish cook evenly and achieve the desired level of doneness.

How to Flip the Fillets

When flipping the fillets, use a nonstick spatula to carefully turn them over. The fish can be delicate, so it's important to handle them gently to avoid breaking them apart. If you're cooking breaded fish, be extra careful as the breading may be prone to falling off.

Adjustments for Different Fish Types

The thickness and type of fish will impact the cooking time and temperature. Thicker fillets, such as cod or halibut, may require a higher temperature or slightly longer cooking time compared to thinner fillets like tilapia. Adjust the temperature and timing accordingly, and always refer to a reliable recipe for specific instructions.

Visual and Temperature Cues for Doneness

To check if your fish is done, look for visual cues such as an opaque and flaky texture. Additionally, use a digital thermometer to ensure the fish has reached an internal temperature of 140-145°F. This temperature range indicates that the fish is fully cooked, safe to eat, and has that perfect flaky texture.

Check for doneness

Checking for doneness is an important step to ensure your frozen fish is cooked safely and thoroughly. Here are some detailed instructions on how to do this:

Firstly, it is recommended to use a digital thermometer to check the internal temperature of the fish. The fish is fully cooked and safe to eat when the internal temperature reaches 140-145°F. This temperature range indicates that the fish has a flaky texture and is opaque, which are signs of doneness.

Secondly, visual cues can also be used to determine if your fish is done. Look for an opaque appearance and a flaky texture. These visual cues indicate that your fish is cooked properly.

Thirdly, you can also check for doneness by inserting a fork into the thickest part of the fish fillet and gently pulling the flesh apart to see if it flakes easily. If the fish flakes easily and is moist and tender, it is likely done.

Lastly, if you've followed a recipe, the recommended cooking time and temperature will give you a good indication of when your fish is done. However, it's important to note that air fryer models vary, so it's always a good idea to check the doneness of your fish a few minutes before the recommended cooking time is up.
