Introduction
Asian Tuna Steak is a delicious and healthy dish featuring tender tuna steaks marinated in a savory sesame-ginger sauce. It’s quick to prepare and perfect for a flavorful weeknight dinner or a special occasion.

Ingredients
- 2 tuna steaks
- 2 tablespoons olive oil
- 1 teaspoon sesame oil
- 1 teaspoon ground ginger
- 1 tablespoon soy sauce
- 1 teaspoon garlic powder
- 1 tablespoon rice vinegar
- 2 tablespoons sesame seeds, divided
- Green onion, sliced (for garnish)
Instructions
- Step 1: In a small bowl, whisk together olive oil, sesame oil, ground ginger, soy sauce, garlic powder, rice vinegar, and half of the sesame seeds to prepare the marinade.
- Step 2: Place the tuna steaks in a shallow dish and pour half of the marinade over them, reserving the rest. Cover and refrigerate for at least 20 minutes or up to overnight.
- Step 3: Preheat your grill to medium-high heat (around 350°F) or heat a cast-iron skillet over medium-high heat if cooking on the stovetop.
- Step 4: Remove the tuna steaks from the marinade, discarding any excess liquid. Press 1 tablespoon of sesame seeds onto the surface of each steak to form a crust.
- Step 5: Grill or sear the tuna steaks for 2-3 minutes per side. While cooking, drizzle a small amount of the reserved marinade over the steaks.
- Step 6: Remove the tuna when the internal temperature reaches 135°F for medium-rare or 145°F for well-done. Let the steaks rest for 2 minutes.
- Step 7: Garnish with sliced green onions and extra sesame seeds. Serve immediately with your favorite sides.
Tips & Variations
- Use sushi-grade tuna for the best texture and flavor.
- Marinate the tuna for up to overnight to deepen the flavors.
- Press sesame seeds firmly onto the tuna to ensure they stick during cooking.
- For a spicy kick, add sriracha or red pepper flakes to the marinade.
- Try a squeeze of fresh lime juice before serving to brighten the dish.
- If you don’t have a grill, a cast-iron skillet works perfectly for searing.
Storage
Store leftover tuna steaks in an airtight container in the refrigerator for up to 2 days. For longer storage, wrap tightly and freeze for up to 1 month. To reheat, warm gently in a pan over low heat for about 30 seconds per side or enjoy cold to avoid drying out the fish.
