How to Make Grilled Sesame-Ginger Tuna Steaks Recipe
Step 1: Make the Marinade
Start by whisking together the olive oil, toasted sesame oil, ground or fresh grated ginger, soy sauce, garlic powder, and rice vinegar in a bowl. This marinade is simple but packs a powerful punch of flavor that will infuse every bite of your tuna steaks.
Step 2: Marinate the Tuna
Place your tuna steaks in a shallow dish or a zip-top bag and pour the marinade over them. Make sure each steak is well coated, then let them rest in the fridge for 20 to 25 minutes. Flip the steaks halfway through to ensure even marination. This step not only tenderizes the fish but also locks in those irresistible sesame-ginger notes.
Step 3: Preheat and Grill the Tuna
Heat up your grill or a grill pan to medium-high. When hot, place the tuna steaks down and sear for about 3 to 4 minutes on each side. If you like your tuna rarer in the center, aim for 2 to 3 minutes per side. The high heat gives you that perfect crust while keeping the inside tender and juicy.
Step 4: Add the Sesame Seeds and Finish
During the last minute of grilling, sprinkle sesame seeds over the tuna steaks to toast them lightly. This adds a delightful crunch and enhances the sesame flavor. Once off the grill, let the steaks rest for a few minutes, allowing the juices to redistribute for maximum juiciness.
Step 5: Garnish and Serve
Top your grilled sesame-ginger tuna steaks with freshly sliced green onions and, if you like, a drizzle of honey or a sprinkle of red pepper flakes for extra depth and a hint of heat. Serve immediately to enjoy the full spectrum of flavors and textures.
How to Serve Grilled Sesame-Ginger Tuna Steaks Recipe

Garnishes
Fresh sliced green onions add a crisp, refreshing bite that perfectly complements the rich, toasted flavors of the tuna. Don’t hesitate to add a sprinkle of sesame seeds and a touch of spicy chili flakes or a light honey drizzle for an extra layer of interest.
Side Dishes
Serve alongside steamed jasmine rice or quinoa to soak up the savory sauce. A simple cucumber salad or roasted vegetables with a light vinaigrette also pairs beautifully, bringing balance and vibrant colors to your plate.
Creative Ways to Present
For a dinner party, slice the tuna steaks thinly and fan them out on a long platter, garnished with microgreens and a drizzle of the marinade reduced into a glaze. Alternatively, serve over a bed of mixed greens for a lighter, elegant meal that feels fresh and satisfying.
Make Ahead and Storage
Storing Leftovers
If you have any leftover tuna steaks, store them in an airtight container in the refrigerator. They will keep well for up to two days, making for a quick and delicious next-day lunch or dinner.
Freezing
While fresh tuna is best enjoyed fresh, you can freeze marinated but uncooked tuna steaks by wrapping them tightly in plastic wrap and placing them in a freezer bag. Use within one month for optimal flavor and texture.
Reheating
To reheat leftover tuna steaks, gently warm them in a skillet over low heat or enjoy them cold in a salad. Avoid overheating, as the delicate fish can dry out quickly.
FAQs
Can I use fresh ginger instead of ground ginger?
Absolutely! Fresh grated ginger provides a brighter, zestier flavor, which many people prefer. Use about one tablespoon of fresh ginger for every two teaspoons of ground ginger.
How do I know when tuna steaks are cooked perfectly?
Tuna cooks quickly and is best enjoyed with a slightly rare center, which means about 2 to 3 minutes per side on high heat. If you prefer more well-done fish, simply increase the grilling time by a minute or two, but be careful not to overcook.
Can I use this marinade for other types of fish?
Yes! This sesame-ginger mixture works wonderfully with firm fish like salmon or swordfish. Just adjust the marinating and grilling time to suit the thickness and delicacy of the fish you choose.
Is there a substitute for sesame oil?
Toasted sesame oil is quite unique, but if you need a substitute, you can use a small amount of toasted peanut oil or increase olive oil slightly. Keep in mind the flavor will be milder.
Can I prepare this recipe without a grill?
Definitely. Use a grill pan or a heavy skillet on the stove-top to achieve a similar sear and flavor. Just make sure to get the pan very hot and cook the tuna steaks in batches to avoid overcrowding.

Optional Ingredients

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 to create a flavorful marinade.
- Marinate the Tuna: Place the tuna steaks in a shallow dish or a zip-top bag. Pour the marinade over the tuna ensuring each steak is coated thoroughly. Refrigerate for 20–25 minutes, flipping the steaks once halfway through the marinating time for even flavor absorption.
- Preheat the Grill: Heat your grill or grill pan to medium-high heat, ensuring it’s hot enough to sear the tuna quickly and lock in juices.
- Grill the Tuna: Place the marinated tuna steaks on the grill and sear for 3–4 minutes per side, depending on the steak’s thickness and your preferred doneness. For a rare center, grill for 2–3 minutes each side.

Notes
- Adjust grilling time based on tuna steak thickness and preferred doneness.
- To toast sesame seeds even more, dry sauté them for a minute before adding to the tuna.
- Use fresh grated ginger for a brighter, more intense ginger flavor compared to ground ginger.
- Marinating longer than 25 minutes may begin to cook the tuna slightly due to the acidity in the marinade.
- Serve with steamed rice or a fresh salad for a complete meal.
