Quick & Easy Sesame Ginger Tuna Tartare

This Ahi Tuna Tartare is fresh, vibrant, and ready in minutes. It also happens to be my personal favorite seafood appetizer! 🥳 Sushi-grade tuna is tossed with lime, soy sauce, and jalapeño for a perfectly balanced, restaurant-worthy appetizer. I love to serve it with crispy wonton chips, but cucumber rounds are a very close second.

Ingredients

For the Marinade

  • 2 Tbsp reduced-sodium soy sauce (use tamari to make gluten-free)
  • 1 Tbsp sesame oil
  • 2 tsp fresh lime juice
  • 1 tsp ginger paste, or 1 tsp grated fresh ginger

For the Tuna

  • 1 lb ahi tuna, fresh, sushi-grade
  • ½ medium ripe avocado, diced
  • 3 Tbsp white onion, very thinly sliced
  • 1 jalapeño, minced, with or without seeds
  • ¼ cup fresh cilantro, finely chopped
  • 1 tsp toasted sesame seeds,
  • Lime wedges
  • Wonton crisps or thin crackers

Instructions

  • Make the marinade. Combine soy sauce, sesame oil, lime juice, and ginger paste in a small bowl, then whisk well. Set aside.
  • Cut the tuna. Using a very sharp knife, cut the tuna into ⅛-inch dice, trimming away any sinew or skin. Place tuna in a large mixing bowl.
  • Add remaining ingredients. Add avocado, onion, jalapeño (remove seeds if you want it mild), cilantro, and 1 tsp sesame seeds. Pour marinade on top, then toss to thoroughly coat. Cover and refrigerate for 15 minutes.
  • To serve. Stir the tartare, then serve with an extra sprinkle of sesame seeds and lime wedges.

Notes

  • Use the best fish you can find, preferably fresh sushi-grade ahi tuna. Salmon, yellowtail, or even finely diced sea scallops are excellent substitutes.
  • Mix just before serving: Prep all ingredients ahead of time, but wait to combine the fish with lime juice until the last minute. The acid will begin to “cook” the fish if it sits too long.
