Ahi Tuna Tacos – a light and refreshing tuna tacos recipe with mango pineapple salsa! Healthy and delicious!


  • 1 batch Mango Pineapple Salsa
  • 1-inch thick tuna steak
  • kosher salt and ground black pepper
  • 2 teaspoons white sesame seeds
  • 1 tablespoon extra-virgin olive oil
  • street taco tortillas 
  • fresh cilantro, chopped
  • lime wedges


  1. Make salsa: combine Mango Pineapple Salsa ingredients together in a medium bowl; set aside. 
  2. Cook tuna steak: Place tuna steak on a plate and sprinkle each side with salt, pepper, and 1 teaspoon of sesame seeds per side. Pat seasoning into each side to make sure they stick. Bring a large cast iron skillet to medium-high heat and drizzle in the oil. When oil just starts to smoke, place tuna steaks in hot skillet. Cook for 30-45 seconds per side (or up to 1 minute if you just barely want it rare in the middle). Remove and let the tuna rest on clean plate for 5 minutes.
  3. Assemble tacos: cut tuna into bite-sized chucks. Take the street taco tortillas and add some salsa and pieces of tuna. Top with fresh cilantro and another squeeze of lime juice. 


  • Make ahead: feel free to make the salsa ahead of time and store in an airtight container in the refrigerator for 2-3 days. 
  • Extra: you might have extra salsa, depending upon how many people you are serving – simply save the rest or serve with tortilla chips!
