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. Add half of the sesame seeds and mix well until combined. This savory marinade is bursting with flavor and will enhance the Asian Tuna Steak beautifully.
Step 2: Marinate the Tuna
Place your fresh tuna steaks in a shallow dish and pour half of the marinade over them, ensuring they are evenly coated. Cover the dish with plastic wrap and refrigerate for at least 20 minutes. For deeper flavor, feel free to marinate for up to overnight. This step helps infuse the tuna with the delightful sesame-ginger essence.
Step 3: Preheat the Grill
While the tuna marinates, preheat your grill to medium-high heat, around 350°F. If using a grill pan, heat it on the stovetop. This temperature is crucial for achieving that perfect sear while keeping the inside tender and juicy. You’ll know it’s hot enough when you can feel the heat rising from the grill.
Step 4: Coat the Tuna
After marination, remove the tuna steaks from the dish, letting the excess marinade drip off. Sprinkle the remaining sesame seeds generously over both sides of the tuna, pressing slightly to adhere. This crunchy coating will provide a wonderful texture to the Asian Tuna Steak as it cooks.
Step 5: Grill the Tuna
Carefully place the seasoned tuna steaks on the preheated grill. Cook for 2-3 minutes on each side, aiming for an internal temperature of 135°F for a perfect medium-rare finish. Keep an eye on the color; the tuna should take on a nice golden crust while remaining tender in the center.
Step 6: Serve
Once cooked to your desired doneness, remove the tuna steaks from the grill and let them rest for a moment. Drizzle with the reserved marinade and garnish with chopped green onions and additional sesame seeds. Serve immediately for a delightful meal featuring your homemade Asian Tuna Steak.

How to Store and Freeze Asian Tuna Steak
Fridge: Store any leftover Asian Tuna Steak in an airtight container in the refrigerator for up to 3 days. Make sure to let it cool down before sealing to maintain freshness.
Freezer: Wrap the cooked tuna steaks tightly in plastic wrap and then in foil. They can be frozen for up to 2 months, but for best quality, consume them sooner.
Reheating: When ready to eat, thaw the frozen tuna overnight in the fridge. Reheat gently in a skillet over low heat or in the microwave wrapped in a damp paper towel to prevent drying out.
Storage Tips: To preserve the tuna’s flavor and texture, avoid refrigerating or freezing with the marinade, as it can turn mushy upon reheating.
Make Ahead Options
These Easy Asian Tuna Steaks are perfect for meal prep! You can marinate the tuna steaks up to 24 hours in advance, allowing the bold flavors of the sesame-ginger marinade to penetrate deeply for unforgettable taste. Simply cover your marinated tuna in an airtight container and refrigerate until you’re ready to cook. If you prefer, you can also prepare the marinade up to 3 days ahead and store it in a sealed jar in the fridge; this will keep the ingredients fresh. When you’re ready to serve, preheat the grill and cook the tuna for just 2-3 minutes per side. This way, you’ll enjoy a truly delicious, homemade Asian Tuna Steak with minimal effort!

Asian Tuna Steak Recipe FAQs
What type of tuna should I use for the best results?
Absolutely, fresh tuna steaks are the star of this dish! Look for bright red, firm steaks without any dark spots. Opt for sustainably sourced fish if possible. If you can’t find fresh tuna, you can also use sushi-grade tuna to ensure the best flavor and texture.
How should I store leftover Asian Tuna Steak?
To keep leftovers fresh, store them in an airtight container in the refrigerator for up to 3 days. It’s important to let the tuna cool to room temperature before sealing it to maintain its moisture. For best results, consume the leftovers cold in salads or wraps.
Can I freeze Asian Tuna Steak?
Yes, you can! Wrap the cooked tuna steaks tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. They can be safely frozen for up to 2 months. When you’re ready to enjoy them, thaw the tuna overnight in the refrigerator and reheat gently to maintain tenderness.
What are some common mistakes to avoid when cooking tuna steaks?
Very! One common mistake is overcooking the tuna, which will lead to a dry texture. For best results, aim for an internal temperature of 135°F for medium-rare. Also, ensure your grill is preheated, and consider using a meat thermometer to check for doneness. A simple tip: avoid pressing down on the tuna with a spatula while it’s cooking to preserve moisture.
Can my pets eat cooked tuna steak?
While cooked tuna is safe for dogs in small amounts as an occasional treat, be cautious with the soy sauce and seasonings, as they can be harmful. Cats can also enjoy a little bit of plain, cooked tuna, but it’s essential to ensure it’s served without marinades or sauces to avoid potential health risks.
Can I modify the marinade for dietary restrictions?
Definitely! If you’re looking to make this dish gluten-free, simply substitute soy sauce with tamari.
