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.
Reheat and reduce the leftover marinade in a small saucepot, and serve with tuna steak, along with mashed cauliflower and fresh tomato salsa (recipes provided in the blog post!)
Place a pan over medium heat. Once the oil is hot add tuna steak and sear for 2 minutes on one side. Flip the tuna and sear the other side for another 2-3 minutes. (For at least 2-3 inches thick steak)
