Whisk together lemon juice, oil, pepper and salt in a shallow nonreactive dish. Add catfish and turn to coat with marinade. Cover and refrigerate for 30 minutes.Advertisement
Preheat grill or broiler.
Grill or broil fish on a lightly oiled rack, turning once, until the fish is opaque, about 10 minutes per inch of thickness. Serve with lemon wedges.
Fish on foil: Fish that flakes easily requires a delicate touch to flip on the grill. If you want to skip turning it over when grilling, measure a piece of foil large enough to hold the fish and coat it with cooking spray. Grill the fish on the foil (without turning) until it flakes easily and reaches an internal temperature of 145°F.
