About this Ahi Tuna Tostada Recipe recipe

Ahi tuna is packed with protein and is easy to prepare. It tastes great and leaves you feeling satisfied without feeling overly stuffed.

For this sesame crusted ahi tuna recipe, I paired the ahi tuna with spicy mango salsa. This salsa can literally go on anything. If you have leftover salsa, try it on grilled chicken, halibut or as a tasty dip with tortilla chips.

To add that extra crunch factor, I loaded the tuna on top of lightly fried and salted wonton tostadas. To finish the dish, I sprinkled a healthy amount of crushed cashews over everything. Oh and don’t forget to dip everything into a dollop of my spicy creamy sauce. This tuna recipe is absolute perfection.

Skip the spicy creamy sauce and use a touch of sriracha or soy sauce to keep things lighter. For a lower carb option, substitute the fried tostada for a lettuce cup. One things for sure, no matter how you dress these sesame encrusted ahi tuna tostadas with spicy mango salsa, they are incredible.


Best enjoyed immediately. Option to refrigerate extra ahi tuna and mango salsa in separate airtight containers. Tostadas are best enjoyed the same day. As they will begin to soften in the sauce. Looking for more sushi grade ahi tuna recipes? Try my tuna poke lettuce cups.

Sesame Encrusted Tuna and Fried Wontons

  • 6-8 ounces sushi grade ahi tuna steak
  • ¼ cup sesame seeds, white or black will work
  • ¼ teaspoon salt
  • 6-8 wonton wrappers
  • 4-6 tablespoons avocado oil, for frying the wontons

Spicy Creamy Sauce

  • ¼ cup mayonnaise
  • 1 tablespoon sriracha
  • 1 tablespoon low sodium soy sauce
  • 1 teaspoon maple syrup



Prepare the Salsa

  • In a large mixing bowl, combine the diced mango, diced pineapple, shallots, diced avocado and jalapeno.
    Next, you'll add the lime, along with the cilantro and a pinch of salt. Gently toss everything together and set it aside.

Prepare the Tuna

  • Pat the tuna dry using a paper towel. Add the sesame seeds to a plate and firmly press the tuna into the seeds making sure the entire tuna is well coated.
  • Gently spray a small skillet with cooking spray and place it over medium high heat.
    Right before you add the sesame encrusted tuna into the pan, season it with some salt. Add the tuna to the hot pan, sear it for 1-2 minutes on each side. Remove from the pan and set the tuna aside.
    Using a sharp knife, thinly slice your tuna. It should be rare on the inside.

Prepare the Fried Wontons

  • In a small skillet, add avocado oil over medium/high heat.
    Add one wonton wrapper at a time into the hot oil. They will cook very fast so have your tongs ready.
    Place the fried wonton wrappers on a paper towel and season them with flaky salt. Repeat until you have 6-8 fried wontons.

Prepare the Spicy Sauce

  • Combine the mayonnaise, maple syrup, low sodium soy sauce, and sriracha in a small bowl. Mix well. Set aside.

Assemble the Dish

  • Add a smear of the spicy sauce to your plate. Next, add a fried wonton chip, and top it with thinly sliced sesame encrusted tuna. Top the tuna with the mango salsa. Serve and enjoy!
