Ingredients

• 2 pieces (6 oz each) fresh ahi tuna steak
• 2 tablespoons low sodium soy sauce
• 1 tablespoon fresh lime juice
• 1 teaspoon sesame oil
• 2 cloves, minced garlic
• 1 teaspoon, finely grated ginger root
• 1 teaspoon crushed red pepper flakes
• 1 small, finely chopped jalapeño
• 2 stalks, finely sliced green onion
• 1 teaspoon toasted sesame seeds
• 1 tablespoon avocado oil
• 2 tablespoons, chopped (optional) cilantro leaves

Directions

Step 1

In a small bowl, whisk together the low sodium soy sauce, fresh lime juice, sesame oil, minced garlic, grated ginger, and crushed red pepper flakes to make the marinade.

Step 2

Place the ahi tuna steaks in a shallow dish or resealable plastic bag and pour the marinade over them. Ensure the steaks are evenly coated and let them marinate in the refrigerator for 15-20 minutes.

Step 3

While the tuna is marinating, prepare the jalapeño, green onions, and cilantro, if using, for garnish.

Step 4

Heat the avocado oil in a nonstick or cast iron skillet over medium-high heat until shimmering.

Step 5

Remove the tuna steaks from the marinade (reserve the marinade) and pat them dry with a paper towel to ensure a good sear.

Step 6

Sear the tuna steaks in the hot skillet, about 1-2 minutes per side for medium-rare or longer if you prefer more doneness.

Step 7

Transfer the tuna steaks to a cutting board and let them rest for 2 minutes before slicing into thin strips.

Step 8

Meanwhile, pour the reserved marinade into the skillet and cook for 1-2 minutes over medium heat to reduce slightly and thicken.

Step 9

Drizzle the reduced marinade over the sliced tuna steaks and garnish with chopped jalapeño, sliced green onions, toasted sesame seeds, and cilantro (if using). Serve immediately.
