This Maple Soy Grilled Tuna features fresh tuna steaks marinated in a simple blend of soy sauce, maple syrup and horseradish, then grilled to tender perfection in just minutes.
Combine the soy sauce, maple syrup and horseradish in a large heavy-duty zip bag; add the tuna to the bag. Turn to cover the tuna in the marinade. Seal and chill for 1 hour, turning occasionally. Remove the tuna from the bag; discard the marinade.
Preheat your grill to high heat. Grill the tuna, covered, over high heat for 2 minutes on each side or to desired degree of doneness.
Notes
For the best results, use high-quality fresh tuna steaks that are similar in thickness for even cooking.
Tuna cooks very quickly and is best served rare to medium-rare, but adjust the cooking time to your preferred doneness.
If using a charcoal grill, make sure the coals are very hot before cooking.
Tamari may be substituted for soy sauce to make this recipe gluten-free.
Do not reuse the marinade after the raw fish has been removed.
Leftover grilled tuna is delicious sliced over salads, rice bowls or tucked into wraps the next day.
