Prepare the swordfish: Start by patting the swordfish steaks dry with a paper towel. This will help achieve a nice crispy texture. Lightly brush each side of the steaks with olive oil.
Season the swordfish: In a small bowl, mix together the minced garlic, lemon zest, lemon juice, salt, and pepper. Rub the seasoning mixture evenly over both sides of the swordfish steaks.
Preheat the air fryer: Set your air fryer to 400°F (200°C) and allow it to preheat for about 3-5 minutes.
Cook the swordfish: Place the seasoned swordfish steaks into the air fryer basket. Cook at 400°F for 8-10 minutes, flipping halfway through. The swordfish should be golden on the outside and opaque in the center.
Serve: Once the swordfish is cooked to perfection, remove it from the air fryer and garnish with fresh herbs like parsley or thyme. Serve with your favorite side dish and enjoy!
