Step‑by‑Step Instructions for Asian Tuna Steak
Step 1: Prepare the Marinade
In a small bowl, whisk together 2 tablespoons of olive oil, 1 tablespoon of sesame oil, 1 teaspoon of ground ginger, 2 tablespoons of soy sauce, 1 teaspoon of garlic powder, and 1 tablespoon of rice vinegar until fully combined. This savory mixture will serve as the marinade for your Asian Tuna Steak, infusing it with rich flavor.
Step 2: Marinate Tuna
Place the tuna steaks in a shallow dish and pour half of the marinade over them, ensuring they are well-coated. Cover the dish with plastic wrap and refrigerate for at least 20 minutes. If you have more time, letting it marinate overnight will enhance the flavors even further, creating a deliciously tender steak.
Step 3: Preheat Grill
While the tuna steaks are marinating, preheat your grill to medium-high heat, about 350°F (175°C). If you’re using a grill pan, place it over medium-high heat on your stovetop. This step is crucial for achieving a perfect sear on the Asian Tuna Steak, creating that irresistible crispy crust.
Step 4: Coat Tuna
Once marinating is complete, remove the tuna from the refrigerator and discard the excess marinade. Roll the tuna steaks in the remaining sesame seeds until evenly coated. This adds a delightful crunch to the outside of the tuna and enhances the presentation of your Asian Tuna Steak.
Step 5: Grill Tuna
Place the tuna steaks on the hot grill and cook for about 2-3 minutes per side. You’re looking for an internal temperature of 135°F (57°C) for medium-rare or 145°F (63°C) for a well-done result. Avoid overcooking to maintain the juicy tenderness that makes this dish so delightful.
Step 6: Serve
Once cooked to your liking, remove the tuna steaks from the grill and drizzle with the reserved marinade. Garnish with sliced green onions and any remaining sesame seeds for an appealing finishing touch. Serve immediately for the best flavor and texture, showcasing your delicious Asian Tuna Steak.

Reheating: Gently reheat the tuna steak in a skillet over low heat, drizzled with a little olive oil or water to prevent drying out, for about 5 minutes.

Expert Tips for Asian Tuna Steak
-
Quality Matters: Always choose fresh, high-quality tuna steaks for the best flavor and tenderness. Fish that’s frozen and thawed properly can also work well.
-
Marinate Wisely: While a 20-minute soak is effective, letting the tuna marinate overnight enhances the flavor even more, ensuring a more robust taste in your Asian Tuna Steak.
-
Mind the Heat: Preheat your grill properly. A hot grill is essential for achieving that beautiful sear and preventing the fish from sticking.
-
Avoid Overcooking: Keep a close eye on cooking times. Tuna steaks are best enjoyed medium-rare to retain their juicy quality. Use a meat thermometer for precision.
-
Use Leftover Marinade: Don’t toss the leftover marinade! It’s perfect for drizzling over the cooked tuna or basting while grilling for extra flavor.
Make Ahead Options
These Asian Tuna Steaks are perfect for busy home cooks looking to save time without sacrificing flavor! You can prepare the sesame-ginger marinade up to 24 hours in advance, allowing the flavors to deepen. Simply whisk together the marinade ingredients and store them in an airtight container in the fridge. The tuna steaks can also be marinated for up to 3 hours; if you marinate overnight, they’ll be even more flavorful! When you’re ready to serve, just coat them with sesame seeds and grill for a quick 2-3 minutes per side. This way, you ensure your Asian Tuna Steak is just as delicious with minimal effort during the week.
