Gorgeous and delicious, sweet and creamy, they’re both at the tippy top of my favorite foods list(s).

Seared Ahi Tuna Mango-Avocado Appetizer Recipe
Prep time
Total time
Serves: Serves 2 as an appetizer
  • 1 (½-pound) sushi grade Ahi tuna fillet (see notes)
  • Grape seed oil for the pan
  • 1 Ataulfo mango (see notes)
  • ½ large, ripe avocado
  • Sea salt and freshly ground black pepper (see notes)
  • Drizzle of Tamari if desired
  • About 2 teaspoons finely chopped chives
  1. Place the Ahi fillet on a clean, dry plate.
  2. Lightly sprinkle all of the sides with sea salt, then either sprinkle or grind black pepper directly onto the top and bottom surfaces of the fillets. The pepper should be a thin, but generous layer.
  3. Coat a small sauté pan with grape seed oil and place it over high heat.
  4. Once the pan is very hot, add the Ahi and sear each side until it's only cooked through ⅛ to ¼-inch, 1 minute or less per side. (If you don't hear a sizzling sound when the tuna hits the pan, it's not hot enough -- wait for the sizzle!)
  5. Remove the seared tuna from the pan and place it on a clean plate. Once it has cooled completely, cut it into thin, evenly sized slices -- about ¼-inch each. Set aside. (You should have at least 14 slices.)
  6. Cut the mango into halves. Then, slice each half into approximately 14 evenly sized slices, about ¼-inch each. HERE'S HOW TO CUT A MANGO.
  7. Cut the avocado into halves. Then, horizontally, slice the half into approximately 14 evenly sized slices, about ¼-inch each. HERE'S HOW TO CUT AN AVOCADO.
  8. Arrange the Ahi, mango, and avocado slices evenly between two appetizer plates -- I like alternating them, but arrange them any way you'd like to.
  9. Drizzle with a bit of Tamari if desired, and sprinkle with the chives.
  10. Serve immediately, or cover the plates with plastic wrap, drizzle the avocados with a bit of lemon juice, and refrigerate them until you're ready. (Up to an hour or so.)
Ideally the Ahi tuna fillet is more or less a square -- you can trim it to be as close to the fruit slices as you can, if that's important to you.

Ataulfo mangoes are my favorite, but use any variety you like -- as long as they're perfectly ripe.

If you can get your hands on some, I love Kampot pepper on my Ahi. Here's why.

    I made this last evening with the Kampot pepper. What a delicious dish, and the taste of the pepper added yet another level of complexity to it. Thank you again for introducing me to Kampot pepper, the Pepper Project, and their noble causes!
