How to Make Asian Sesame-Ginger Tuna Steak with Green Onions Recipe
Step 1: Prepare the Marinade
Start by whisking together olive oil, sesame oil, ground ginger, soy sauce, garlic powder, rice vinegar, and half of the sesame seeds. This marinade is packed with umami and fragrant notes that soak beautifully into the tuna, setting the tone for an unforgettable dish.
Step 2: Marinate the Tuna
Pour half the marinade over your fresh tuna steaks, making sure both sides get coated well. Reserve the other half for later. Cover the tuna and refrigerate for at least 20 minutes, giving the flavors a chance to work their magic. For even deeper flavor, you can marinate it overnight.
Step 3: Preheat the Grill
While the tuna marinates, preheat your grill to medium-high heat, about 350°F. A hot grill is key to achieving that gorgeous sear and locking in all the delicious juices inside the tuna steaks.
Step 4: Coat the Tuna
Remove the tuna steaks from the marinade and discard any excess liquid. Now, coat each steak generously with a tablespoon of sesame seeds. This step creates a delightful crust that adds crunch and visual appeal when grilled.
Step 5: Grill the Tuna
Place the sesame-crusted tuna directly onto the hot grill. Grill for about 2 to 3 minutes per side, depending on your preferred doneness. Use the reserved marinade to drizzle over the steaks as they cook, enhancing both moisture and flavor. For a juicy, medium-rare finish, aim for an internal temperature of 135°F, while well-done cooks to 145°F.
Step 6: Serve and Enjoy
Once grilled to perfection, remove your tuna steaks from the heat. Top them with the remaining marinade, fresh sliced green onions, and a sprinkle of extra sesame seeds for that final fragrant touch. Serve immediately to enjoy the full burst of flavors and textures.

Garnishes
Beyond the sliced green onions and extra sesame seeds, consider adding a wedge of lime or a sprinkle of chili flakes for those who love a touch of heat. These small additions brighten the dish and add exciting contrasts.
Side Dishes
This tuna recipe pairs beautifully with steamed jasmine rice or fluffy quinoa, helping soak up all the luscious marinade drippings. A side of lightly sautéed or steamed Asian greens like bok choy or snap peas adds a fresh, crisp counterbalance to the richness of the tuna.
Creative Ways to Present
For a stylish twist, slice the grilled tuna steak thinly and arrange it atop an Asian slaw or mixed greens salad. Drizzle a little extra sesame oil and soy sauce with a sprinkle of toasted sesame seeds and green onions for a bright, restaurant-quality presentation.
Make Ahead and Storage
Storing Leftovers
Store any leftover tuna steaks in an airtight container in the refrigerator for up to 2 days. Because tuna is best enjoyed fresh, try to consume leftovers quickly to preserve texture and flavor.
Freezing
It’s best not to freeze cooked tuna steaks, as the texture can become dry and crumbly once thawed. If you want to freeze, do so only with the raw tuna prepared in the marinade, and use within 1 month for best results.
Reheating
Reheat leftovers gently by warming in a skillet with a drizzle of sesame oil or soy sauce over low heat to avoid overcooking or drying out the tuna. Alternatively, enjoy the tuna cold atop a salad for a refreshing meal.
FAQs
Can I use other types of fish for this recipe?
Absolutely! While tuna steaks work wonderfully for their meaty texture and bold flavor, you can experiment with salmon or swordfish steaks, which also hold up nicely to grilling and absorb the marinade beautifully.
Is it necessary to grill the tuna, or can I pan-sear it?
Grilling imparts a delightful smoky flavor and attractive char marks, but pan-searing is an excellent alternative if you don’t have a grill. Use a hot, heavy skillet and cook for about the same time to achieve a great crust.
How long can I marinate the tuna before cooking?
For best results, marinate the tuna steaks for at least 20 minutes but no more than 24 hours. Over-marinating, especially with acidic ingredients like rice vinegar, can start to ‘cook’ the fish and affect texture.
What’s the best way to tell when tuna is done?
Tuna is best enjoyed medium-rare for moistness and flavor. Aim for an internal temperature of 135°F. If you prefer it well-done, let it reach 145°F, but be aware it will be firmer and less tender.
Can I prepare this recipe for a larger group?
Definitely! Just multiply the ingredients accordingly and marinate the tuna in batches if needed. This recipe scales well, making it perfect for dinners with friends or family gatherings.
