- 4 tuna steaks (about 6 oz each): Use fresh, high-quality tuna for the best texture and flavor.
- 4 tbsp olive oil: Helps create a smooth marinade and prevents sticking on the grill.
- 2 tsp sesame oil (toasted adds extra flavor): Adds a deep, nutty aroma that’s essential to the dish.
- 2 tsp ground ginger or 1 tbsp fresh grated ginger: Gives a lively, spicy brightness that pairs perfectly with the fish.
- 2 tbsp soy sauce: Brings the savory umami punch that makes this recipe standout.
- 2 tsp garlic powder: Adds a gentle garlic warmth without overpowering the marinade.
- 2 tbsp rice vinegar: Introduces a mild acidity that balances the richness of the oils.
- 4 tbsp sesame seeds, divided (white or black): Toasted on the grill for a crunchy, toasty finish.
- Sliced green onion, for garnish: Fresh and mild, it adds a pop of color and crispness.
- Optional twist – 1 tbsp honey or maple syrup: For a subtle sweet-savory contrast that enhances depth.
- Optional heat – ½ tsp red pepper flakes or a drizzle of sriracha: Adds a playful kick for spice lovers.
How to Make Grilled Sesame-Ginger Tuna Steaks Recipe
Step 1: Make the Marinade
Start by whisking together olive oil, toasted sesame oil, freshly grated or ground ginger, soy sauce, garlic powder, and rice vinegar in a bowl. This combination forms the flavorful base that saturates the tuna with that signature bold, umami-packed taste.
Step 2: Marinate the Tuna
Lay your tuna steaks in a shallow dish or place them inside a zip-top bag for easy marinating. Pour the marinade over the fish, ensuring each steak is thoroughly coated. Let them rest comfortably in the refrigerator for 20 to 25 minutes, flipping once halfway through to maximize flavor absorption without losing the perfect texture.
Step 3: Preheat and Grill
Get your grill or grill pan nice and hot, heating it over medium-high to create a sear-worthy surface. Place the tuna steaks on the grill and let them cook for 3 to 4 minutes per side, depending on thickness and desired doneness. If you prefer tuna with a rare, melt-in-your-mouth center, aim for around 2 to 3 minutes per side to keep it juicy and tender.
Step 4: Add Sesame Seeds and Finish
During the last minute of grilling, sprinkle the divided sesame seeds over the steaks to toast them lightly, giving your dish that essential crunchy and nutty character. Once cooked, remove the tuna from heat and allow it to rest for a few minutes; this helps the juices redistribute for maximum tenderness.
How to Serve Grilled Sesame-Ginger Tuna Steaks Recipe

Garnishes
Top your beautifully grilled tuna with thinly sliced green onions to add freshness and a mild oniony crunch. For a little extra flavor, drizzle with honey or a few red pepper flakes, or even a splash of sriracha, to suit your taste and elevate the dish.
Side Dishes
This recipe pairs wonderfully with light, summery sides such as steamed jasmine rice, a crisp Asian slaw, or a chilled cucumber salad tossed with rice vinegar and sesame oil. These sides complement the bold sesame-ginger flavors and keep the meal well-balanced and satisfying.
Creative Ways to Present
For an eye-catching presentation, serve the tuna steaks sliced into thin strips over a bed of mixed greens or lightly dressed soba noodles. You can also arrange them alongside avocado slices and a sprinkle of toasted sesame seeds on a stylish wooden board to impress your guests without any fuss.
Make Ahead and Storage
Storing Leftovers
If you have leftover tuna steaks, store them in an airtight container in the refrigerator for up to 2 days. Keep them chilled and away from strong-smelling foods to preserve their fresh, vibrant flavor.
Freezing
While fresh tuna is best enjoyed soon after cooking, you can freeze leftover grilled tuna steaks by wrapping them tightly in plastic wrap and then placing them in a freezer-safe bag. Use within 1 month for optimal taste and texture.
Reheating
To reheat, gently warm the tuna over low heat in a pan or in the oven at a low temperature to avoid overcooking. Because the steak is best enjoyed medium-rare to medium, be careful not to dry it out during reheating.
FAQs
Can I use fresh ginger instead of ground ginger?
Absolutely! Fresh ginger adds a brighter, zesty spice to the marinade and is often preferred for its more vibrant flavor. Use about one tablespoon of fresh grated ginger to replace two teaspoons of ground ginger.
How do I know when the tuna steaks are done?
Tuna steaks are best when still slightly pink in the center. A good rule of thumb is to grill for about 3 to 4 minutes per side for medium, or 2 to 3 minutes per side if you like it rare. Overcooking can lead to a dry texture.
Can I use a stovetop grill pan instead of an outdoor grill?
Yes! A grill pan works perfectly when outdoor grilling isn’t an option. Just preheat the pan over medium-high heat and follow the same cooking times to achieve those beautiful grill marks and that incredible sear.
Is there a way to make this recipe vegan or vegetarian?
While this recipe is designed for tuna, you can easily adapt the marinade and method for tofu or thick slices of eggplant for a vegan-friendly alternative. Just be sure to press tofu well and grill gently to maintain texture.
Can I prepare the marinade in advance?
Definitely! The marinade can be made a day ahead and stored in the refrigerator. This also allows the flavors to deepen, which can add even more punch to your Grilled Sesame-Ginger Tuna Steaks Recipe.

- Sliced green onion, for garnish
Optional Ingredients
- 1 tbsp honey or maple syrup (for a sweet-savory balance)

Instructions
- Make the Marinade: In a bowl, whisk together olive oil, toasted sesame oil, ground or fresh grated ginger, soy sauce, garlic powder, and rice vinegar until well combined.
- Marinate the Tuna: Place the tuna steaks in a shallow dish or sealable zip-top bag. Pour the marinade over the steaks, ensuring each piece is fully coated. Refrigerate for 20 to 25 minutes, turning the tuna halfway through for even flavor absorption.
- Preheat the Grill: Heat your outdoor grill or grill pan over medium-high heat until hot and ready to sear the tuna steaks.

- Toast Sesame Seeds: During the last minute of grilling, sprinkle the sesame seeds over the tuna steaks to add a toasty crunch and enhance the nutty flavor.
- Rest and Garnish: Remove the tuna steaks from the grill and let them rest for a few minutes. Top with sliced green onions and, if desired, add a drizzle of honey or maple syrup for sweetness or sprinkle red pepper flakes or sriracha for heat before serving.
Notes
- For best flavor, use fresh tuna steaks that are at least 1-inch thick.
- Adjust grilling time depending on your preferred doneness—less time for rare, more time for well done.
- The optional honey or maple syrup provides a nice sweet balance to the savory marinade.
- If you prefer a gluten-free soy sauce alternative, tamari works well.
- Serve with steamed rice, a fresh green salad, or grilled vegetables for a complete meal.
