Make this restaurant-quality spicy tuna tartare at home. This easy, no-cook seafood appetizer features fresh ahi tuna, creamy avocado, and crispy wonton chips for a gourmet starter.

Ingredients

Scale
  • 1 lb sushi-grade ahi tuna, finely diced
  • 1 ripe avocado, diced
  • 2 tablespoons soy sauce
  • 1 tablespoon sesame oil
  • 1 tablespoon rice vinegar
  • 1 teaspoon sriracha (or more for extra spice)
  • 1 teaspoon fresh ginger, grated
  • 1 scallion, thinly sliced
  • 1 teaspoon toasted sesame seeds
  • Pinch of salt
  • Wonton wrappers, cut into triangles for frying
  • Vegetable oil for frying

Instructions

  1. Prepare the wonton crisps: Heat about 1 inch of vegetable oil in a small pot to 350°F (175°C). Fry wonton triangles in batches until golden brown and crisp, about 1-2 minutes per side. Remove with a slotted spoon and drain on paper towels. Lightly salt immediately.
  2. Prepare the tuna: In a medium bowl, combine the diced sushi-grade tuna, soy sauce, sesame oil, rice vinegar, sriracha, grated ginger, and salt. Gently fold the ingredients together until the tuna is evenly coated. Do not overmix.
  3. Fold in the avocado: Gently fold in the diced avocado and half of the sliced scallions into the tuna mixture. You want the avocado to remain in distinct pieces for texture.
  4. Assemble the tartare: Use a ring mold or a small bowl to shape the tuna tartare mixture onto serving plates. Press lightly to hold the shape.
  5. Garnish and serve: Top the tartare with the remaining sliced scallions and toasted sesame seeds. Serve immediately with the homemade wonton crisps for scooping.

Notes

  • You must use high-quality, sushi-grade tuna for this raw preparation. Ask your fishmonger for the freshest cut available.
  • For a Nobu style flavor, you can add a small amount of Kewpie mayonnaise to the dressing mixture for extra creaminess.
  • If you do not want to fry wontons, use store-bought crispy crackers or cucumber slices as an alternative base.
