These air fryer ahi tuna steak slices are marinated in dark sauce, then perfectly fried in an air fryer (or stovetop instructions included) until medium-rare, have a smoky flavor, and simply just melt in your mouth.
Leave to marinate in the fridge for 20 minutes. Reserve the marinade for later if using. Preheat air fryer to 370 Fahrenheit according to manufacturer directions.
Once preheated transfer tuna steaks to the air fryer basket and fry for 1 minute. Open the air fryer, turn the tuna steaks over, air fry for another 1 minute.
