Ingredients

• 4 ounces each Ahi tuna steaks
• 2 tablespoons Low-sodium soy sauce
• 2 tablespoons Lemon juice
• 1 teaspoon Sesame oil
• 1 teaspoon, grated Fresh ginger
• 1 minced Garlic clove
• 0.5 teaspoon Black pepper
• 2 tablespoons White sesame seeds
• 2 tablespoons Black sesame seeds
• 1 tablespoon Olive oil
• 0.25 teaspoon Salt

Directions

Step 1

In a small bowl, whisk together the low-sodium soy sauce, lemon juice, sesame oil, grated ginger, and minced garlic to make the marinade.

Step 2

Place the Ahi tuna steaks in a shallow dish and pour the marinade over them, ensuring they are well-coated. Cover and allow to marinate for 10 minutes at room temperature.

Step 3

In another small bowl, mix the white and black sesame seeds together. Set aside.

Step 4

After the tuna has marinated, remove it from the marinade and pat dry with paper towels. Season each steak with salt and black pepper.

Step 5

Coat the tuna steaks evenly with the sesame seed mixture, pressing gently to adhere the seeds to the surface.

Step 6

Heat the olive oil in a non-stick skillet over medium-high heat. Once the oil is shimmering, add the tuna steaks.

Step 7

Sear the tuna for about 2-3 minutes on each side for rare, or longer if desired, ensuring the sesame crust is nicely golden and crispy.

Step 8

Remove the tuna steaks from the pan and let rest for a minute before slicing. Serve immediately, pairing it with a side of fresh salad or steamed vegetables for a complete heart-healthy meal.
