Learn to cook restaurant-quality tuna steaks at home using a cast iron skillet. This recipe delivers a perfect sear and a quick, flavorful soy-ginger glaze for a high-protein, fast dinner.

Ingredients

Scale
  • 2 (6-ounce) tuna steaks (Ahi or Yellowfin)
  • 1 tablespoon olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon soy sauce
  • 1 tablespoon fresh ginger, grated
  • 1 teaspoon honey
  • 1 clove garlic, minced
  • 1 teaspoon sesame oil

Instructions

  1. Pat the tuna steaks completely dry with paper towels. Season both sides evenly with salt and pepper.
  2. In a small bowl, whisk together the soy sauce, grated ginger, honey, minced garlic, and sesame oil to create the glaze. Set aside.
  3. Place a cast iron skillet over high heat. Add the olive oil and let it heat until it just begins to smoke slightly. This high heat is key for a good sear.
  4. Carefully place the tuna steaks in the hot skillet. Sear for 1.5 to 2 minutes per side for rare to medium-rare results. Adjust time based on your preferred doneness.
  5. Remove the tuna steaks from the skillet and place them on a cutting board. Let them rest for 2 minutes.
  6. Brush the tops of the rested tuna steaks generously with the prepared soy-ginger glaze.
  7. Slice the tuna steaks against the grain into half-inch thick pieces. Serve immediately.

Notes

  • For a blackened tuna steak finish, mix 1 tablespoon of Cajun seasoning into the salt and pepper before seasoning the fish.
  • If you prefer a thicker crust, lightly coat the seasoned steaks in sesame seeds before searing.
  • Pair this lean seafood entree with steamed asparagus or a fresh mixed greens salad for a complete meal.
