These seared ahi tuna smash tacos are a bright, flavor-forward dinner that feels light and fresh while still being exciting and simple to make. Think smash burger technique, but with sushi-grade ahi tuna pressed thin on a tortilla and quickly seared. Each taco is finished with a crunchy snap pea and herb salad, creamy avocado, crispy shallots and a drizzle of sriracha mayo. Ready in about 30 minutes, they’re perfect for a weeknight or a fun twist for taco night.
Smash tacos with a poke-inspired twist
This recipe starts with sushi-grade ahi tuna combined with garlic, ginger, green onions, soy sauce and a little mayo, pulsed briefly until it forms a sticky, paste-like mixture. Spread that thinly on tortillas, sear the tuna side until golden and slightly charred, then top with a bright snap pea and herb salad, sliced avocado, crispy shallots and spicy mayo. The combination of textures—silky tuna, crunchy salad and crispy onions—makes every bite sing.
For the herb salad, I recommend using a mix of green onion tops, Thai basil, mint and cilantro. Thinly slicing the snap peas on the bias gives the salad the best crunch and texture.
This is the kind of recipe I make when I’m really craving it; it’s not always the most kid-friendly meal, so I sometimes serve my girls a modified version like a cheese quesadilla and sides while the adults enjoy the fully assembled tacos. Small adjustments keep everyone happy without making a whole separate dinner.
Do it. Make these tacos. They’re worth it.
What you’ll need:
- Look for sushi-grade fresh tuna steaks at your seafood counter. If it’s not on display, ask the fishmonger—many stores will bring it out from the back.
- Fresh garlic and ginger are best, but paste is an acceptable shortcut that speeds things up.
- Use the white parts of the green onions in the tuna mixture for a milder onion flavor, and save the green tops for the salad.
- Low-sodium soy sauce helps control salt; use tamari or coconut aminos for a gluten-free alternative.
- Fajita-size flour tortillas give a nice crispy edge and a good filling-to-tortilla ratio. Corn tortillas can be used for a gluten-free option.
- The herb mix—mint, basil, cilantro and green onion tops—is essential. Use them together so the salad feels substantial, not just a garnish.
- Crispy shallots or fried onions add a satisfying crunch. Any store-bought crispy onions will work.
Step-by-step overview
Start by tossing the sliced snap peas with chopped herbs, rice vinegar, toasted sesame oil and sesame seeds. Season lightly with salt so the salad stays crisp and bright rather than soggy.
Pat the tuna dry, cut into large chunks, then pulse briefly with garlic, ginger, the white parts of the green onions, soy sauce, mayo and a pinch of salt and pepper until you have a mostly smooth, sticky mixture. Lay out tortillas and use lightly oiled hands to press the tuna into a thin layer that reaches the edges—this helps achieve a good sear.
Heat a nonstick skillet with a splash of high-heat oil. Place each tortilla, tuna-side down, press gently and cook about a minute until the tuna develops a golden, lightly charred crust. Flip briefly to warm and crisp the tortilla. Repeat until all tacos are cooked.
Assemble by piling on the snap pea herb salad, avocado slices, crispy shallots, a generous drizzle of sriracha mayo and a squeeze of lime. Serve immediately.
That’s it—tacos ready to enjoy.
FAQs
Canned tuna won’t give the same texture or flavor and won’t hold together like fresh ahi. For best results, use sushi-grade ahi tuna.
You could substitute ground chicken, turkey or pork, but I haven’t tested this recipe with those proteins. They should produce a tasty alternative though.
Cut the tuna into roughly 2-inch cubes and marinate briefly in the seasonings (without mayo). Sear the cubes in a hot skillet about 30 seconds per side until seared. Assemble tacos with the seared cubes and the remaining toppings. It won’t be a smash taco, but it will still be delicious.
Store the cooked tacos and the salad separately. Reheat tacos in a skillet or air fryer briefly to crisp them up, then add the fresh toppings before serving.
I’ll take at least five ahi tuna tacos, please and thanks.

Ingredients
Ahi Tuna Tacos
- 1 lb sushi-grade ahi tuna steaks, cut into 2–3-inch chunks
- 1 tablespoon garlic, minced or paste
- 1 tablespoon ginger, grated or paste
- 1/4 cup green onions, thinly sliced (white parts only)
- 2 tablespoons low-sodium soy sauce
- 2 teaspoons mayo
- Pinch kosher salt and freshly cracked black pepper
- 7–8 6-inch flour tortillas (fajita-size)
- Splash of avocado oil for searing
Snappy Herb Salad
- 6 oz snap peas, thinly sliced (about 2 heaping cups)
- 1 1/2 cups fresh herbs – Thai basil, mint, cilantro and green onion tops
- 1 tablespoon rice vinegar
- 2 teaspoons toasted sesame oil
- 1 teaspoon sesame seeds
- Pinch of salt
Toppings
- Crispy shallots
- Avocado slices
- Sriracha mayo
- Lime wedges
Instructions
- Make the snappy herb salad: In a bowl combine sliced snap peas, chopped herbs, rice vinegar, toasted sesame oil and sesame seeds. Season lightly with salt and set aside.
- Prepare the tuna: Pat tuna dry and cut into large chunks. Pulse in a food processor with garlic, ginger, white parts of the green onions, soy sauce, mayo and a pinch of salt and pepper until a mostly smooth paste forms (10–15 seconds).
- Form the tacos: Lay out tortillas and divide the tuna mixture among them. With lightly oiled hands press the mixture into a thin, even layer to the edges of each tortilla.
- Cook: Heat a nonstick skillet with a splash of avocado oil over medium-high heat. Place a tortilla tuna-side down, press gently and cook about 1 minute until charred. Flip briefly to warm and crisp the tortilla. Repeat with remaining tacos.
- Assemble: Top each taco with the snap pea herb salad, avocado, crispy shallots, sriracha mayo and a squeeze of lime. Serve immediately.
Notes
Crispy shallots – Any crispy fried onions work; I like the small packages sold near salad toppings or in the produce section.
Sriracha mayo – Mix mayonnaise and sriracha to taste. A suggested ratio is 1/3 cup mayo to 1 teaspoon sriracha; add a little sweet chili sauce if you prefer sweet heat.
