Halibut, with its mild, slightly sweet flavor and firm, flaky texture, is a favorite among seafood lovers. Known for being versatile and nutrient-rich, this white fish is an excellent source of protein, omega-3 fatty acids, and essential vitamins such as B12 and D. Cooking halibut from frozen can be intimidating, especially for those new to air fryers, but this kitchen appliance simplifies the process, ensuring a crispy exterior and tender, juicy interior without the need for deep frying or lengthy preparation. This guide explores the optimal techniques, timing, and temperatures for air frying frozen halibut, helping you achieve a perfectly cooked fish every time.
Air fryers cook by circulating hot air at high speeds, mimicking the effects of frying while reducing oil usage. Temperature is critical in ensuring halibut cooks evenly while remaining moist. The ideal temperature for cooking frozen halibut in an air fryer is 400°F (204°C).
At this temperature, the fish develops a lightly crisped outer layer within minutes, while the inside cooks thoroughly without drying out. Temperatures lower than 375°F may result in uneven cooking and a rubbery texture, while temperatures above 425°F can overcook the exterior before the interior is fully done.

Cooking time depends on the thickness of the fillets and whether the halibut is coated or seasoned. On average, frozen halibut fillets that are 1 to 1.5 inches thick require 10-12 minutes at 400°F. For thinner fillets (around 0.5 inches), 8-10 minutes is sufficient, while thicker cuts may need up to 14 minutes.
It’s recommended to flip the fillets halfway through the cooking time to ensure even heat distribution and prevent over-browning on one side.
Proper doneness ensures the fish is both safe to eat and enjoyable in texture. Indicators include:

Cooking time directly affects texture and doneness.
Yes, you can cook frozen halibut directly in an air fryer. The appliance circulates hot air evenly, which allows the fish to cook thoroughly without prior thawing. However, it is important to adjust the cooking time and temperature to ensure the center cooks fully while the exterior does not overcook.
A typical recommendation is to cook frozen halibut at 400°F (200°C) for 12-15 minutes, flipping halfway through. The exact time may vary depending on the thickness of the fillet and the air fryer model, so using a food thermometer to ensure the internal temperature reaches 145°F (63°C) is ideal.
Yes, you can season frozen halibut, but it is best to apply light seasoning or a thin layer of oil to help the spices adhere. Salt, pepper, garlic powder, paprika, and lemon juice are common options. For more even seasoning, some cooks prefer to season halfway through cooking after the surface softens slightly.
Using oil is optional but recommended to prevent the fish from sticking and to enhance browning. A light brush or spray of oil on both sides is usually sufficient. Avoid over-oiling, as the air fryer produces a crispy exterior with minimal fat.
The best method is to check the internal temperature with a meat thermometer, which should reach 145°F (63°C). The fish should also be opaque and flake easily with a fork. The exterior should be golden and slightly crisp but not burnt.
Yes, flipping the fillet halfway through the cooking process helps ensure even cooking and browning on both sides. Skipping this step may result in uneven texture, with one side more cooked than the other.
Yes, frozen halibut with skin can be cooked in an air fryer. Leaving the skin on can help protect the fish from drying out and adds extra flavor and crispiness. Cook skin-side down first for best results and adjust cooking time slightly for thicker fillets.
