Ingredients
This recipe makes 4 generous servings.
For the Tuna & Marinade
- 4 (6-ounce) tuna steaks, about 1-inch thick
- 1/4 cup low-sodium soy sauce (or tamari for gluten-free)
- 2 tablespoons toasted sesame oil
- 1/4 cup fresh orange juice (from about 1 orange)
- 2 tablespoons fresh lime juice (from about 1 lime)
- 1 tablespoon honey or maple syrup
- 1 tablespoon fresh ginger, grated
- 2 cloves garlic, minced
- 1 teaspoon toasted sesame seeds (for the marinade)
- 1/4 teaspoon black pepper
- 1 tablespoon olive oil or avocado oil, for grilling
For the Garnish
- 2 green onions, thinly sliced
- 1 teaspoon toasted sesame seeds
- Orange zest, for sprinkling (optional, but highly recommended)
Step-by-Step Instructions
-
Step 1: Prepare the Marinade
In a medium bowl, whisk together the soy sauce, sesame oil, orange juice, lime juice, honey (or maple syrup), grated ginger, minced garlic, 1 teaspoon toasted sesame seeds, and black pepper. Mix until everything is well combined and the honey has dissolved. This creates a beautifully balanced and aromatic base for your tuna.
-
Step 2: Marinate the Tuna
Place the tuna steaks in a shallow dish or a resealable plastic bag. Pour the prepared marinade over the tuna, ensuring each steak is fully coated. Cover the dish or seal the bag and refrigerate for at least 15 minutes, but no longer than 30 minutes. Small tip: Tuna is delicate. Marinating for too long can “cook” the fish with the acid, changing its texture. Stick to the recommended time for best results.
-
Step 3: Preheat the Grill
While the tuna is marinating, preheat your grill to medium-high heat. You want a good, hot surface to get that perfect sear. Clean the grill grates thoroughly with a wire brush. Small tip: Lightly oil the clean grill grates with a paper towel dipped in olive oil to prevent the tuna from sticking. Be careful when oiling a hot grill.
-
Step 4: Grill the Tuna
Remove the tuna steaks from the marinade, letting any excess drip off. Discard the remaining marinade. Place the tuna steaks on the hot, oiled grill. Grill for 2-4 minutes per side for medium-rare, or longer for your desired doneness. Tuna cooks very quickly, so keep a close eye on it. Small tip: For a perfectly cooked tuna steak, aim for an internal temperature of 125-130°F (52-54°C) for medium-rare. Use an instant-read thermometer for accuracy.
-
Step 5: Rest the Tuna
Once cooked to your liking, carefully remove the tuna steaks from the grill and transfer them to a cutting board or serving platter. Let the tuna rest for 5 minutes. This allows the juices to redistribute, ensuring a more tender and flavorful steak. You can slice the tuna against the grain if you prefer, or serve it whole.
-
Step 6: Garnish and Serve
Arrange the rested tuna steaks on individual plates. Sprinkle generously with the sliced green onions and the remaining toasted sesame seeds. For an extra pop of freshness and aroma, add a little orange zest over the top. Serve immediately and enjoy the incredible flavors!
Tips & Variations
- Gluten-Free Option: Easily make this recipe gluten-free by ensuring you use tamari instead of traditional soy sauce. All other ingredients are naturally gluten-free.
- Vegan/Vegetarian Option: This marinade is fantastic with plant-based proteins! Try marinating thick slices of firm tofu, tempeh, or large portobello mushroom caps. Grill them until tender and beautifully charred.
- Add More Vegetables or Protein: For a more substantial meal, grill some bell pepper strips, asparagus spears, or snap peas alongside your tuna. You could also serve it over a bed of protein-rich quinoa or brown rice.
- Spicy Version: If you love a little heat, add 1/2 teaspoon of sriracha or a pinch of red pepper flakes to the marinade. You can also drizzle a little chili oil over the finished dish.
- Broiling or Pan-Searing: No grill? No problem! You can achieve similar results by broiling the tuna steaks for 4-6 minutes, flipping halfway, or pan-searing them in a hot, oiled skillet for 2-3 minutes per side.

Health Benefits
This Sesame Citrus Grilled Tuna Steaks recipe is not just delicious; it’s packed with incredible health benefits. It’s a dish you can feel great about enjoying regularly!
Tuna is a fantastic source of lean protein, essential for muscle repair and growth. It’s also rich in omega-3 fatty acids, particularly EPA and DHA, which are crucial for heart health, brain function, and reducing inflammation throughout the body. These healthy fats are often lacking in modern diets.
The citrus in the marinade, especially the orange and lime juice, provides a powerful dose of Vitamin C. Vitamin C is a vital antioxidant that supports your immune system, promotes healthy skin by aiding collagen production, and helps protect your cells from damage. It also helps your body absorb iron more efficiently.
Ginger and garlic, key components of our marinade, are renowned for their medicinal properties. Ginger is a potent anti-inflammatory and can aid digestion, while garlic is known for its immune-boosting and cardiovascular benefits. Both are packed with antioxidants that contribute to overall well-being.
Finally, the humble sesame seeds contribute healthy monounsaturated and polyunsaturated fats, along with important minerals like calcium, magnesium, and iron. They add a lovely nutty flavor and a nutritional boost to every bite.
Serving Suggestions
- Serve your grilled tuna with a side of fluffy brown rice or quinoa to soak up all the delicious marinade flavors.
- Pair it with a simple steamed green vegetable like asparagus, broccoli, or green beans for a light and balanced meal.
- Create a vibrant bowl by flaking the tuna over a bed of mixed greens, adding cucumber, avocado, and a light vinaigrette.
- For a refreshing side, a simple Asian-inspired cucumber salad with rice vinegar and a touch of chili flakes would be perfect.
Storage Tips
Leftover Sesame Citrus Grilled Tuna Steaks can be stored in an airtight container in the refrigerator for up to 2-3 days. While you can technically freeze cooked tuna, it’s not recommended as the texture can become dry and fibrous upon thawing. To reheat, gently warm the tuna in a skillet over low heat or in the microwave on a low setting, just until heated through, to prevent it from drying out. It’s also delicious served cold or at room temperature flaked over a salad.
