Essential Ingredients
Marinade:
- 2 tablespoons fresh ginger, thinly julienned
- 2.5 tablespoons freshly squeezed Key lime juice
- 4 tablespoons cold-pressed toasted sesame oil
- 4 tablespoons traditionally brewed Tamari soy sauce
- 1 tablespoon coarsely ground Tellicherry black pepper
Main:
- 52 ounces yellowfin ahi tuna steaks, approximately 1 inch thick
Preparation Steps
- Thaw the ahi tuna steaks if frozen. Gently pat them dry with paper towels to remove excess moisture.
- In a bowl, combine Key lime juice, Tamari soy sauce, toasted sesame oil, and julienned fresh ginger. Mix thoroughly to create the marinade.
- Place the tuna steaks in a shallow dish or large zip-lock bag. Coat them fully with the marinade. Cover or seal tightly and refrigerate for at least 30 minutes.
- Preheat a grill to high heat or a skillet over medium-high heat. Ensure the grill grates or skillet are well-oiled to prevent sticking.
- Remove the marinated tuna steaks from the refrigerator and let them come to room temperature for about 10 minutes. Sprinkle Tellicherry black pepper evenly on both sides of each steak.
- Place the tuna steaks on the preheated grill or skillet. Grill or sear for 1-2 minutes per side for rare to medium-rare doneness, depending on your preference. Avoid overcooking to maintain tenderness and a pink center.
- Let the cooked tuna rest for a few minutes. Slice against the grain into thin, even slices. Arrange on a serving platter, garnish with additional fresh ginger if desired, and serve immediately.

Health Benefits
Ahi tuna is an excellent source of lean protein and omega-3 fatty acids, which promote heart health. It’s also rich in vitamins B6 and B12. The use of ginger and sesame oil not only enhances the flavor but also adds anti-inflammatory and antioxidant benefits.
Serving Suggestions
Serve seared ahi tuna with a side of steamed vegetables or a light salad. For a more traditional pairing, serve with jasmine rice or a soba noodle salad. A drizzle of wasabi aioli or soy glaze can add a burst of flavor.
Creative Variations
- Spicy Tuna: Add a pinch of red pepper flakes to the marinade for extra heat.
- Sesame Crusted: Roll the marinated tuna in white and black sesame seeds before searing for a crunchy texture.
- Citrus Twist: Substitute Key lime juice with yuzu or orange juice for a different flavor profile.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Serve cold over salads or in sushi bowls to preserve texture.
Pro Tips
- Always use sushi-grade ahi tuna for the best quality and safety.
- Do not overcook the tuna, as it can become dry and lose its buttery texture.
- Use a hot grill or skillet to achieve a quick sear and maintain a rare center.
