Learn to cook perfect, restaurant-style tuna steaks quickly using a hot pan and a simple garlic herb butter finish.

Ingredients

Scale
  • 2 (6 ounce) tuna steaks, about 1 inch thick
  • 1 tablespoon olive oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 4 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 tablespoon fresh parsley, chopped
  • 1 teaspoon fresh thyme leaves

Instructions

  1. Pat the tuna steaks completely dry with paper towels. Season both sides evenly with salt and pepper.
  2. Heat the olive oil in a heavy-bottomed skillet, preferably cast iron, over medium-high heat until the oil shimmers.
  3. Carefully place the tuna steaks in the hot skillet. Sear for 1.5 to 2 minutes per side for rare to medium-rare. Adjust time slightly for your preferred doneness.
  4. Remove the skillet from the heat. Add the butter, minced garlic, parsley, and thyme to the pan.
  5. As the butter melts, tilt the pan and use a spoon to baste the melted garlic herb butter over the tuna steaks for about 30 seconds.
  6. Remove the tuna steaks immediately to a cutting board. Let them rest for 2 minutes before slicing against the grain.
  7. Serve immediately with the pan sauce spooned over the top.

Notes

  • For a great sear, make sure your pan is very hot before adding the fish.
  • Use sushi-grade or sashimi-grade tuna for the best texture and safety when serving rare.
  • If you prefer a different flavor, substitute the herb butter with 3 tablespoons of soy sauce mixed with 1 teaspoon of grated fresh ginger during the last minute of cooking.
