Learn how to cook restaurant-quality tuna steaks at home using a cast iron skillet. This quick recipe delivers a perfect sear and tender center, finished with a simple garlic herb butter.

Ingredients

Scale
  • 2 (6-ounce) fresh tuna steaks (Ahi or Yellowfin)
  • 1 tablespoon olive oil
  • 1 teaspoon coarse salt
  • 1/2 teaspoon black pepper
  • 1/2 cup (1 stick) unsalted butter
  • 3 cloves garlic, minced
  • 1 tablespoon fresh parsley, chopped
  • 1 teaspoon fresh thyme leaves
  • 1 tablespoon soy sauce (for finishing glaze)

Instructions

  1. Pat the tuna steaks completely dry using paper towels. Season both sides evenly with salt and pepper.
  2. Place a cast iron skillet over high heat. Add the olive oil. Wait until the oil is shimmering and almost smoking.
  3. Carefully place the tuna steaks in the hot skillet. Sear for 1.5 to 2 minutes per side for rare to medium-rare results. Do not move the steaks while searing to achieve a good crust.
  4. Remove the tuna steaks from the skillet and set them aside on a plate. Tent loosely with foil.
  5. Reduce the heat to medium-low. Add the butter to the same skillet. Let it melt.
  6. Add the minced garlic to the melted butter and cook for about 30 seconds until fragrant. Do not let the garlic brown.
  7. Stir in the chopped parsley and thyme. Cook for 15 seconds more.
  8. Remove the skillet from the heat. Drizzle the soy sauce into the butter mixture and swirl to combine, creating a quick glaze.
  9. Slice the tuna steaks against the grain into half-inch thick pieces. Drizzle the garlic herb butter sauce over the sliced tuna before serving immediately.

Notes

  • For a blackened tuna steak flavor, mix 1 tablespoon of your favorite Cajun seasoning into the salt and pepper before coating the steaks.
  • If you prefer a soy-ginger glaze, add 1 teaspoon of grated fresh ginger to the butter mixture along with the garlic.
  • Use high-quality, sushi-grade tuna for the best texture and flavor when searing.
