Ingredients

• 2 pieces (about 6 ounces each) Ahi tuna steaks
• 2 tablespoons Olive oil
• 2 tablespoons Soy sauce
• 1 tablespoon Lemon juice
• 2 cloves Garlic, minced
• 1 teaspoon Ground black pepper
• 2 tablespoons Sesame seeds
• 0.5 teaspoon Salt
• 2 stalks Green onions, sliced

Directions

Step 1

In a small bowl, whisk together olive oil, soy sauce, lemon juice, minced garlic, ground black pepper, and salt to create the marinade.

Step 2

Place the ahi tuna steaks in a shallow dish and pour the marinade over them, ensuring that they are well coated. Let the steaks marinate for about 10 minutes, flipping them halfway through.

Step 3

Remove the tuna steaks from the marinade and lightly press sesame seeds onto both sides of each steak.

Step 4

Heat a non-stick skillet over medium-high heat.

Step 5

Once the skillet is hot, add the tuna steaks and sear for 2-3 minutes on each side for rare, or slightly longer if you prefer the tuna more cooked.

Step 6

Remove the tuna from the skillet and let it rest for a couple of minutes.

Step 7

Slice the rested ahi tuna into 1/4-inch thick slices.

Step 8

Serve the seared ahi tuna topped with sliced green onions, along with any remaining marinade drizzled over the top for extra flavor.
