Make restaurant-quality tuna steaks quickly using a simple soy-ginger marinade. You can pan-sear or grill these steaks for a tender, flavorful, healthy dinner ready in under 15 minutes.

Ingredients

Scale
  • 2 (6 ounce) tuna steaks (about 1 inch thick)
  • 1 tablespoon soy sauce
  • 1 tablespoon fresh ginger, grated
  • 1 teaspoon sesame oil
  • 1 clove garlic, minced
  • 1 teaspoon honey or brown sugar
  • 1 tablespoon olive oil or avocado oil (for searing)
  • Optional: Sesame seeds for garnish

Instructions

  1. Prepare the marinade: In a small bowl, whisk together the soy sauce, grated ginger, sesame oil, minced garlic, and honey.
  2. Place the tuna steaks in a shallow dish or zip-top bag. Pour the marinade over the steaks, turning to coat them evenly. Let the tuna marinate for 10 to 15 minutes at room temperature. Do not marinate longer, as the soy sauce can begin to cure the fish.
  3. Remove the tuna from the marinade and pat them dry with paper towels. Discard the remaining marinade.
  4. Heat the olive oil in a heavy skillet (cast iron works well) over medium-high heat until it shimmers, or preheat your grill to medium-high.
  5. Carefully place the tuna steaks in the hot skillet or on the grill. Sear for 1.5 to 2 minutes per side for rare (cool, red center), or 3 to 4 minutes per side for medium-rare. You want a nice crust on the outside.
  6. Remove the tuna from the heat immediately. Let the steaks rest on a cutting board for 3 minutes before slicing.
  7. Slice the tuna against the grain, sprinkle with sesame seeds if desired, and serve immediately.

Notes

  • For a blackened crust, use a high-smoke point oil like avocado oil and increase the heat slightly.
  • If you prefer to grill, ensure your grates are clean and oiled to prevent sticking.
  • Serve these tuna steaks with quick side dishes like steamed asparagus or a simple rice pilaf.
