Ahi is the Hawaiian name for yellowfin and bigeye tunas. Both of these types of tuna have flesh that ranges in color from pink—usually found in smaller fish—to a deep red found in larger fish that live deeper in the ocean.

When choosing your tuna steaks, you may have the option to buy ahi tuna that is "sashimi" or "sushi" grade. This simply means that the fish has been frozen to kill any parasites before it is consumed or prepared. There are no official standards for labeling fish sushi or sashimi-grade; they're really just marketing terms. 

Serve your tuna steaks with a salad, baked sweet potatoes, or green beans.


  • Balsamic Reduction:
  • 6 tablespoons/90 milliliters aged balsamic vinegar
  • 1 medium lemon (juiced)
  • 1 garlic clove (peeled and halved)

  • 1 1/2 teaspoons/7 1/2 milliliters Kosher salt
  • 1 teaspoon/5 milliliters coriander (ground)
  • 1 teaspoon/5 milliliters paprika
  • 1/4 teaspoon/5 milliliters cayenne pepper
  • 1 1/2 teaspoons/22 1/2 milliliters black pepper (coarsely ground)

  2. Make the balsamic reduction: Place the balsamic vinegar, lemon juice, and garlic in a small saucepan over medium-low heat.

  3. Simmer until the mixture reduces by half. Turn off the heat and reserve until needed. This sauce does not have to be hot for serving. The reduction will thicken slightly as it cools.

  4. Slice the tuna fillet into four rectangular steaks of equal size. In a small bowl, combine the salt, coriander, paprika, and cayenne pepper. Lay the tuna steaks out on a plate and sprinkle the spice mixture evenly on all sides.

  5. Evenly coat the tuna steaks with the freshly ground black pepper, and gently press it in, so that it adheres to the surface, being careful not to smash the flesh.

  6. Place a thick-bottomed frying pan or cast-iron skillet over medium-high heat. Add the oil and swirl to coat the pan. When you see small wisps of smoke, add the tuna to the pan and sear the steaks for about one minute per side, or until the desired doneness is reached.

  • A word about preparation: Seared ahi tuna is best cooked rare to achieve this signature meaty flavor and buttery texture. When it's overcooked and becomes too dry, that's when it becomes fishy tasting.
