How to Grill Ahi Tuna Perfectly

1. Marinate the Tuna:
In a shallow dish, whisk together soy sauce, sesame oil, olive oil, lemon juice, ginger, and garlic. Add tuna steaks and coat evenly. Cover and marinate in the refrigerator for 20–30 minutes.

2. Preheat the Grill:
Heat your grill to high. If using a grill pan indoors, heat it until very hot but not smoking.

3. Remove from Marinade:
Take tuna out of the marinade and pat it dry lightly with a paper towel. Season both sides with salt and pepper.

4. Grill the Tuna:
Place tuna on the grill and sear for about 1.5–2 minutes per side for rare, 2.5–3 minutes for medium-rare. Do not overcook.

5. Rest & Slice:
Let rest for 2–3 minutes. Slice thinly against the grain or serve whole.
