How to Make – Step by Step

Cooking ahi tuna can feel intimidating if you’ve never done it before, but the method is quick and foolproof. The key is a hot pan, a short sear, and confidence in leaving the center rare for that perfect tender bite. With this step-by-step approach, you’ll feel like a pro in no time.

1. Make the Marinade – In a small bowl, whisk together soy sauce, sesame oil, ginger, garlic, rice vinegar, and honey.
2. Marinate the Tuna – Place the tuna steaks in a shallow dish and pour marinade over. Let sit for 10–15 minutes (or up to 30 for stronger flavor).
3. Heat the Pan – Place a skillet or cast-iron pan over medium-high heat until very hot.
4. Sear the Tuna – Remove tuna from marinade and pat dry. Sear each side for 1–2 minutes, depending on thickness, until the outside is browned but the inside remains rare to medium-rare.
5. Garnish & Serve – Slice tuna against the grain, sprinkle with sesame seeds and green onions, and serve with lime wedges.
