Grilled Tuna Steak

Instructions

1. Prepare the marinade
   In a bowl, combine olive oil, lemon juice, minced garlic, rosemary, thyme, salt, pepper, and lemon zest. Whisk until well blended.
2. Marinate the tuna
   Place tuna steaks in a shallow dish and pour the marinade over them. Turn to coat both sides. Cover and refrigerate for at least 30 minutes, but no longer than 1 hour as the acid in the lemon juice can start to 'cook' the fish.
3. Prepare the grill
   Preheat your grill to high heat (450-500°F). Oil the grates to prevent sticking. If using a grill pan, heat it over high heat until very hot.
4. Grill the tuna
   Remove tuna from the marinade, letting excess drip off. Place tuna steaks on the hot grill and cook for 1-2 minutes per side for rare (cool, red center), 3 minutes per side for medium-rare (warm, red center), or 5 minutes per side for medium (warm, pink center). Avoid overcooking as tuna becomes dry quickly.
5. Rest the tuna
   Transfer the grilled tuna to a cutting board and let rest for 5 minutes to allow the juices to redistribute throughout the fish.
6. Slice and serve
   If desired, slice the tuna steaks against the grain into 1/2-inch thick slices. Arrange on plates, sprinkle with capers if using, and serve immediately with lemon wedges.
