Step‑by‑Step Instructions for Asian Tuna Steak
Step 1: Prepare the Marinade
In a small mixing 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. To enhance the flavor profile of your Asian Tuna Steak, mix in half of the sesame seeds. Set aside the remaining sesame seeds for later use.
Step 2: Marinate the Tuna
Place two tuna steaks in a shallow dish and pour half of the savory marinade over them. Make sure to cover the steaks thoroughly. Seal with plastic wrap or a lid and refrigerate for a minimum of 20 minutes and up to overnight. This marinating time will infuse the fish with delicious flavors and ensure a juicy result.
Step 3: Preheat the Grill
While the tuna marinates, preheat your grill to medium-high heat, aiming for around 350°F. This ensures a perfect sear when you cook the Asian Tuna Steak, which locks in moisture while creating that desirable crust. If you prefer pan-searing, get your skillet hot with a drizzle of olive oil instead.
Step 4: Coat the Tuna
After marinating, take the tuna steaks out of the fridge and discard the excess marinade. On a clean plate, coat each steak generously with the reserved sesame seeds to form a crunchy crust. This step adds delightful texture and nutty flavor to your Asian Tuna Steak.
Step 5: Grill the Tuna
Carefully place the tuna steaks on the preheated grill. Cook for about 2-3 minutes on each side, or until they reach the desired doneness: 135°F for medium-rare or 145°F for well-done. As they cook, look for a beautifully seared exterior while keeping the center tender and slightly pink.
Step 6: Serve
Once cooked to perfection, remove the tuna steaks from the grill and let them rest for a minute. Drizzle with the reserved marinade for extra flavor, and garnish with chopped green onions for freshness. Your Asian Tuna Steak is now ready to impress—it’s best served immediately alongside your favorite sides!

How to Store and Freeze Asian Tuna Steak
Fridge: Store leftover Asian Tuna Steak in an airtight container for up to 3 days to maintain freshness. It’s best to reheat gently to avoid drying out the fish.
Freezer: If you have uncooked marinated tuna steaks, freeze them in a resealable bag for up to 3 months. Thaw in the refrigerator before grilling or cooking.
Reheating: For reheating leftovers, place the tuna steaks in a skillet over low heat with a splash of water or broth. Cover to steam for 3-5 minutes until warmed through without losing moisture.
Airtight Storage: Wrap cooked tuna steaks tightly in plastic wrap before placing them in the fridge or freezer to prevent freezer burn and maintain great taste.
Make Ahead Options
These Asian Tuna Steaks are perfect for meal prep, saving you time on busy weeknights! You can marinate the tuna up to 24 hours in advance. Simply whisk together all the marinade ingredients, coat the tuna steaks, and refrigerate them, ensuring they’re covered tightly to lock in flavor and prevent dryness. If you’re short on time, a 20-minute marination is also sufficient! When you’re ready to serve, simply remove the steaks from the fridge, coat them with sesame seeds, and grill them to your desired doneness. This approach ensures you’ll enjoy tender, flavorful tuna steaks with minimal effort when dinner time rolls around!
