DO-AHEAD TIP: Marinate fish for 1 hour (see recipe).
Place fish in a large zipper-topped plastic bag. In a medium bowl, whisk together remaining ingredients (lemon juice through salt and pepper); pour mixture over fish then seal bag, turn to coat and refrigerate for 1 hour.
Heat an indoor grill pan over medium heat until hot. Remove swordfish steaks from marinade (discarding marinade and bag); grill for 5 minutes per side or until fish flakes easily when tested with a fork.
