Key Ingredients for Tuna Tartare with Avocado
For the Tuna:
- 1 lb sushi-grade tuna (yellowfin or bigeye)
- 2 tablespoons soy sauce
- 1 tablespoon sesame oil
- 1 tablespoon rice vinegar
- 1 teaspoon sriracha (optional)
- 1 green onion, finely chopped
For the Avocado:
- 2 ripe avocados
- 1 tablespoon lime juice
- 1 tablespoon olive oil
- Salt and pepper to taste
For Garnish:
- 1 tablespoon sesame seeds
- 1 radish, thinly sliced
- Fresh cilantro leaves
- Wonton chips or crackers for serving

Step-by-Step Instructions
Step 1: Prepare the Tuna
Remove the tuna from refrigeration 10 minutes before cutting to bring it to room temperature. Using a sharp knife, cut the tuna into small, uniform cubes about ¼-inch in size. The key is keeping your knife very sharp for clean cuts that won’t tear the fish.
Step 2: Season the Tuna
In a medium bowl, gently combine the diced tuna with soy sauce, sesame oil, rice vinegar, and sriracha if using. Add the chopped green onion and mix carefully with a spoon to avoid breaking up the fish. Let it marinate for 5 minutes.
Step 3: Prepare the Avocado
Cut the avocados in half, remove the pits, and dice them into similar-sized pieces as the tuna. Drizzle with lime juice immediately to prevent browning. Add olive oil and season with salt and pepper.
Step 4: Combine and Plate
Gently fold the seasoned avocado into the tuna mixture, being careful not to mash the avocado. Taste and adjust seasoning as needed. Using a ring mold or small bowl, create neat portions on individual plates.
Step 5: Garnish and Serve
Sprinkle sesame seeds over each portion. Arrange radish slices and cilantro leaves around the plate. Serve immediately with wonton chips or your favorite crackers.
What to Serve Tuna Tartare with Avocado With
This elegant appetizer pairs beautifully with crisp white wines like Sauvignon Blanc or Pinot Grigio. For non-alcoholic options, try sparkling water with cucumber or a light green tea.
Complement the dish with Asian-inspired sides like edamame, cucumber salad, or seaweed salad. The clean, fresh flavors work well before heavier main courses like grilled salmon or chicken teriyaki.
For a complete meal, serve alongside miso soup and steamed rice. The tartare also makes an excellent topping for sushi bowls or poke bowls.
Top Tips for Perfecting Tuna Tartare with Avocado
Choose the Right Tuna
Always buy sushi-grade tuna from a reputable fishmonger. The fish should smell like the ocean, not “fishy.” If you can’t find sushi-grade tuna, this recipe won’t work safely with regular tuna.
Master the Knife Work
Keep your knife extremely sharp and clean. Dull knives will tear the fish and create mushy textures. Cut with confidence in smooth, decisive motions.
Timing is Everything
Prepare this dish just before serving. The lime juice will start to “cook” the fish if left too long, and the avocado may brown despite the lime juice protection.
Temperature Matters
Serve the tartare slightly chilled but not ice-cold. Remove from the refrigerator 5 minutes before serving for the best texture and flavor.
Storing and Reheating Tips
Storage: Tuna tartare is best consumed immediately after preparation. If you must store it, keep it refrigerated for no more than 24 hours in an airtight container. The quality will decline significantly after this time.
Freezing: This dish is not suitable for freezing as the texture of both the tuna and avocado will be compromised when thawed.
Make-Ahead Tips: You can dice the tuna and prepare the seasonings up to 2 hours ahead. Keep the tuna mixture and avocado separate until ready to serve. Mix them together just before plating.
Leftover Ideas: If you have leftover tuna tartare, it can be used as a topping for salads or rice bowls within 24 hours. Never leave it at room temperature for more than 2 hours.
Frequently Asked Questions
Can I use frozen tuna for this recipe?
You can use previously frozen sushi-grade tuna, but make sure it was properly frozen and thawed. Never use regular frozen tuna from the grocery store as it’s not safe to eat raw.
How do I know if my tuna is fresh enough?
Fresh sushi-grade tuna should have a bright red color, firm texture, and smell like the ocean. Avoid tuna that looks dull, feels mushy, or has a strong fishy smell.
Can I make this recipe dairy-free?
Yes! This recipe is naturally dairy-free. Just make sure your serving crackers or chips are also dairy-free if needed.
What can I substitute for avocado?
You can try diced cucumber for crunch, or mango for sweetness. However, avocado’s creamy texture is unique and hard to replicate perfectly.
How long can I keep leftover tuna tartare?
Consume within 24 hours for best quality and safety. The dish is really meant to be eaten fresh.
Is this recipe keto-friendly?
Yes! This recipe is naturally low-carb and keto-friendly. Just serve with cucumber slices or lettuce cups instead of crackers.
