Prepare your grill and let it heat up for about 15 minutes until it reaches a temperature of 500°F. If you are using a pellet grill, we recommend using Alder, Apple, or Maple pellets.
Brush the swordfish steak on both sides with oil and season generously with salt.
Grill the swordfish steaks over high heat, as close to the heat as possible, turning once after 5 minutes, getting good grill marks. Flip the steak over and grill the other side for another 2-3 minutes. Transfer the fish to a platter and divide in half. Serve with Lemon-Dill Aioli sauce. Serves 2
