Fish and seafood in an air fryer are prepared with the needs of a low-carb base in mind. An air fryer circulates hot air around the food and quickly creates browning with little added fat. Arrange food in one layer, avoid overcrowding the basket, and check doneness earlier than in a regular oven.

The key is not to overheat the delicate protein, to keep the juices, and to add a fatty keto dressing, butter, or creamy sauce.
