Ahi Tuna Tartare may sound fancy, but it’s surprisingly simple to prepare and makes an impressive starter for guests. The most important step is sourcing sushi‑grade tuna steaks. I’ve found excellent sushi‑grade tuna in the freezer sections at stores like Central Market and Whole Foods. Once you have good tuna, this bright, zesty tartare comes together quickly and bursts with fresh flavors.


Ingredients:
- About 1 lb sushi‑grade tuna steaks, thawed if frozen
- 1/4 cup extra virgin olive oil
- 1 tsp freshly grated ginger
- 3 tbsp fresh lime juice
- 2 tbsp tamari (or soy sauce)
- 1 tsp toasted sesame oil
- 2 cloves garlic, minced
- 1/2 tsp kosher salt, or to taste
- Zest of 1/2 lime
- 1 tsp sriracha (adjust to taste)
- 1 jalapeño, seeds removed and finely chopped
- 1/4 cup thinly sliced scallions
- 1 ripe avocado, diced
- 1/4 cup freshly chopped cilantro
Method:
- With a very sharp knife, trim and cut the tuna into roughly 1/4‑inch cubes. Place the tuna in a large mixing bowl.
- In a small bowl, whisk together the olive oil, grated ginger, lime juice, tamari, sesame oil, minced garlic, salt, lime zest and sriracha until well combined.
- Pour the dressing over the cubed tuna and toss gently to coat each piece.
- Fold in the finely chopped jalapeño and scallions, mixing gently to distribute evenly without bruising the fish.
- Cover and refrigerate if desired to let the flavors meld for up to 2 hours. If serving immediately, proceed to the next step.
- Right before serving, gently fold in the diced avocado and the chopped cilantro so they remain fresh and creamy.
- Serving suggestion: Spoon the tartare onto thin, neutral crackers or small toasts for an elegant appetizer. You can also serve it over cucumber rounds, endive leaves, or small wonton crisps.

Tips: Always buy the freshest sushi‑grade tuna you can find and keep it well chilled until ready to prepare. Adjust heat and salt to your preference. For a lighter variation, swap half the olive oil for a neutral oil or reduce the oil slightly and add a splash of rice vinegar for brightness.
