Flavored with Cajun seasonings and lemon, this tilapia in air fryer is low calorie and keto (has no panko or bread crumbs) and goes well with (cauliflower) rice and vegetables such as Brussels Sprouts.
Grease the air fryer basket either by spraying no stick cooking spray or by brushing it with a vegetable oil such as olive oil. Cook in a single layer for 8-10 minutes (depending on the size or thickness of the fillets), flipping halfway through with a silicone spatula if you can.
If needed, cook them in batches, leaving a space between the fillets for hot air to circulate and cook them evenly. They have cooked fully when they show a brown exterior and are flaky in the thickest part.
