Imagine sushi and a crispy taco had a beautiful, flavor-packed baby. That’s this ahi tuna tostada.
Cool, buttery raw tuna. Crunchy fried tostada shell. Creamy avocado. Spicy mayo. It’s bright, fast, and dangerously addictive. No stove, no oven, and absolutely no cooking skills required—just sharp knife skills and good fish.
Prep the Tuna
Pat tuna dry with paper towels. Cut into small ¼-inch cubes.
Make the Sauce
In a small bowl, whisk together sriracha mayo, soy sauce, sesame oil, and lime juice.
Toss It Together
Place cubed tuna in a medium bowl. Pour half the sauce over it. Gently toss to coat.
Save the remaining sauce for drizzling.
Mash or Slice Avocado
Mash avocado lightly with a fork (or slice thinly). Season with a pinch of salt.
Assemble
Spread mashed avocado on each tostada shell.
Top with the sauced tuna.
Drizzle remaining sauce on top.
Garnish and Serve
Sprinkle with green onions, sesame seeds, and jalapeño if using.
Serve immediately with lime wedges. Eat within 5 minutes—soggy tostadas are sad tostadas.

Storage Notes
Do Not Store Assembled
Tostadas get soggy almost immediately. This is a eat-right-now recipe.
Prep Ahead Instead:
- Tuna: Cube and mix with sauce up to 2 hours ahead. Keep refrigerated.
- Avocado: Mash just before serving (it browns fast).
- Tostada shells: Store in a sealed bag at room temperature for weeks.
Leftover Tuna Warning:
Raw tuna does not keep once mixed with sauce. Make only what you’ll eat immediately.
