Total Time2 hours 5 minutes
Course: Main Course
Cuisine: American
Servings: 4 servings/1 steak per serving

Ingredients

  • 4 tuna steaks ( 4-6 ounces each, fresh or frozen)
  • ¼ cup soy sauce
  • 2 tbsps olive oil
  • 2 tbsps fresh lemon juice
  • 2 tbsps fresh orange juice
  • 2 tbsps honey
  • 3 cloves of garlic, minced
  • 1 tablespoon fresh ginger, grated
  • 1 teaspoon seasame oil
  • 1 teaspoon black pepper
  • ½ teaspoon salt
  • 2 green onions, thinly sliced (for garnish)
  • Sesame seeds (for garnish)
  • Lemon wedges (for garnish)

Instructions

  • In a medium bowl, whisk together the soy sauce, olive oil, lemon juice, orange juice, honey, minced garlic, grated ginger, sesame oil, black pepper, and salt until well combined.
  • Place the tuna steaks in a resealable plastic bag or a shallow dish. Pour the marinade over the tuna steaks, ensuring they are evenly coated. Seal  the bag or cover the dish and refrigerate for at least 30 minutes or up to 2 hours for more flavor.
  • Preheat your grill pan or grill to medium-high heat (about 400°F/200°C). Add a little oil or cooking spray to prevent the tuna from sticking.
  • Remove the tuna steaks from the marinade, allowing any excess to drip off. Discard the marinade.
  • Grill the tuna for 2-3 minutes per side for rare to medium-rare doneness. Adjust the cooking time based on your preferred level of doneness, but be careful not to overcook, as tuna can become dry quickly.
  • Transfer the grilled tuna steaks to a serving platter. Garnish with thinly sliced green onions and sesame seeds. Serve with lemon wedges on the side for squeezing over the fish.

Notes

  • Tuna is best served rare to medium-rare. It should have a seared outer layer while remaining pink and tender in the center. Use a meat thermometer if needed, aiming for an internal temperature of 115°F (46°C) for rare and 125°F (52°C) for medium-rare.
  • These tuna steaks pair well with grilled vegetables such as Brussels sprouts, asparagus, roasted potatoes, or a fresh cucumber salad. For a more Asian-inspired meal, serve with steamed rice and stir-fried vegetables.
  • If you have leftover tuna, you can flake it and put it into salads or make it into a tuna salad for sandwiches.
  • If using frozen tuna steaks, thaw in the refrigerator and follow the instructions on the packaging for best results. 
  • Make sure that the grill or grill pan is clean prior to cooking the tuna.
