Killer Tuna Taco Recipe

Prepare tuna

Pat the diced tuna dry with paper towels to remove excess moisture. Place in a medium mixing bowl.

Add mayonnaise, soy sauce, sriracha, sesame oil, and fresh lime juice to the bowl with tuna. Gently fold until pieces are evenly coated—avoid mashing the tuna; you want distinct chunks.

Fold in thinly sliced green onions and chopped cilantro. Season with salt and freshly ground black pepper. Taste and adjust: add more sriracha for heat or more lime for brightness.

Cover and refrigerate the tuna mixture for 10–15 minutes to let flavors marry (optional but recommended).

While the tuna chills, prepare vegetables: finely shred the red cabbage, julienne the carrot, and thinly slice the radish. Arrange in a small bowl or platter for assembly.

Slice the avocado just before assembly to prevent browning and set aside with lime wedges.

If using store-bought creamy cilantro-lime sauce, stir briefly to loosen. For a quick homemade version: blend 1/2 cup plain yogurt or mayo with 2 tbs chopped cilantro, 1 tbs lime juice, 1 small garlic clove, pinch of salt, and water to thin to desired consistency.

Place toasted sesame seeds and extra sriracha nearby for finishing touches.

Warm tortillas: heat a large skillet over medium-high. Add the neutral oil or butter and swirl to coat. Warm each tortilla 20–30 seconds per side until pliable and slightly charred in spots. Keep wrapped in a clean towel to stay warm.

Lay a warm tortilla flat. Spoon about 1.5 to 2.0 ounces (roughly 3 tbs) of the chilled tuna mixture into the center of each tortilla.

Top with a small handful of shredded red cabbage, a spoonful of julienned carrot, and a few radish slices for crunch and color.

Add 2–3 slices of avocado on top of the veggies. Drizzle 1–2 tbs of the creamy cilantro-lime sauce over the filling and a scant drizzle of extra sriracha if you want more heat.

Sprinkle toasted sesame seeds and additional chopped cilantro or green onion if desired. Serve with lime wedges alongside to squeeze over the tacos just before eating.

Serve immediately while tortillas are warm. Leftover tuna can be kept covered in the refrigerator for up to 24 hours (best eaten same day).
