You can easily cook High Liner frozen fish products in an air fryer, as the appliance circulates intense, rapid dry heat that crisps breaded and battered coatings exceptionally well while keeping the interior tender and flaky. Preparing them this way typically requires preheating the air fryer to around 380 to 400 degrees Fahrenheit and cooking the frozen fillets for roughly 10 to 14 minutes, shaking or flipping halfway through to ensure an even, golden-brown crunch.
