A Completely Irresistible (and Foolproof!) Tuna Tartare!
Tuna tartare is one of those dishes that keeps us coming back for more. It’s fresh, flavorful, and unbelievably easy to prepare. Best of all? Just like with a classic beef tartare, here’s no cooking required! While often enjoyed in warm weather, I firmly believe it deserves a spot on any holiday appetizer table. Not only is it a showstopper, but it’s also significantly more budget-friendly to make at home than ordering it at a restaurant.

Ingredient Notes
For the Tuna:
- 8 oz fresh sushi-grade ahi tuna, finely diced
- 2 tbsp white onion, finely chopped
- 1 small jalapeño, minced (use half for mild, whole for extra heat)
- 1 tsp toasted sesame seeds, plus more for serving
- 1 small avocado, diced
- 2 tbsp chopped fresh cilantro (optional, for garnish)
For the Marinade:
- 2 tbsp low-sodium soy sauce
- 1 tsp ginger paste (or freshly grated ginger)
- 1 tbsp fresh lime juice
- 1 tsp toasted sesame oil
Beyond that, you’ll want to make sure you have lime wedges, chips or wonton crackers, and Sriracha for serving.

Simple Instructions
- Prepare the marinade. In a small bowl, whisk together the soy sauce, ginger paste, lime juice, and sesame oil. Set aside.
- Dice the tuna. Using a very sharp knife, cut the ahi tuna into small ⅛-inch cubes, discarding any sinew or skin. Place the diced tuna in a mixing bowl.
- Assemble the tartare. Add the onion, jalapeño, sesame seeds, and avocado to the bowl with the tuna. Pour the marinade over the top and gently toss to combine. Cover and refrigerate for 15 minutes to allow the flavors to meld.
- Serve and enjoy! Before serving, give the tartare a quick stir. Garnish with extra sesame seeds, a squeeze of lime juice, and fresh cilantro. Serve with wonton chips, crackers, or inside endive leaves for a beautiful presentation.

Expert Tips
- Use the freshest fish possible. Since tuna tartare is served raw, it’s crucial to use sushi-grade ahi tuna from a trusted fishmonger.
- Avoid over-marinating. Letting the tuna sit too long in lime juice will start to “cook” it, similar to ceviche. To prevent this, mix the marinade in just before serving.
- Want to prep ahead? Chop all the ingredients and store them separately in the fridge. When ready to serve, toss everything together with the marinade.

Serving Suggestions
Tuna tartare is an incredibly versatile dish! Here are some of my favorite ways to serve it:
- With wonton crisps or crackers for a crunchy contrast.
- In endive leaves or lettuce cups for a low-carb option.
- As a taco filling for a creative twist.
- Stuffed inside an avocado for an elegant presentation.
- With a drizzle of sriracha for those who love extra spice.
- Or simply eaten straight from the bowl with a spoon!

Equipment
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.
