Prep the Tuna: Start by patting the tuna steaks dry with paper towels to remove any excess moisture. Lightly coat both sides of the tuna steaks with a drizzle of olive oil, ensuring even coverage for a crispy, golden finish.
Season: In a small bowl, combine the salt, pepper, garlic powder, paprika, and thyme. Rub the seasoning blend evenly over both sides of the tuna steaks.
Preheat the Air Fryer: Set your air fryer to 400°F (200°C) and let it preheat for 2-3 minutes.
Cook the Tuna: Place the seasoned tuna steaks in the air fryer basket in a single layer. Cook for 3-4 minutes per side for medium-rare. If you prefer your tuna well-done, cook for an additional 1-2 minutes per side.
Serve: Once cooked, remove the tuna steaks from the air fryer. Serve with fresh lemon wedges and your favorite dipping sauce or side salad.
