Directions

1. Preheat grill to high. Whisk oil, garlic, salt and pepper together in a small bowl. Thoroughly pat fish dry with paper towels; place the fish on a baking sheet. Brush about ¼ cup garlic oil on both sides of the fish; reserve the remaining garlic oil. Let the fish stand while the grill preheats.
2. Once the grill is preheated, thoroughly oil the grill rack (see Tip). Place lemon halves, cut sides down, on the rack. Grill, uncovered, until the lemons are well charred on the cut sides, about 4 minutes. Transfer to a serving plate.
3. Meanwhile, place the fish in a grill basket. Place the basket directly onto the grill rack; grill for 4 minutes. Without flipping, brush the fish with the remaining garlic oil. Continue grilling until the fish is cooked through and a thermometer inserted in the thickest portion registers 145°F, 2 to 4 more minutes. (The fish should release from the basket and be slightly flaky on the edges and opaque on top.) Transfer the fish to the plate with the lemons. Squeeze the lemons over the fish and sprinkle with chives.
