Why This Recipe Works (And Why Most People Overcomplicate It)
Most tartare recipes read like a chemistry exam. Long ingredient lists. Fancy equipment. Techniques that assume you went to culinary school.
This one doesn't.
Tuna Tartare with Avocado & Sesame Crisps strips it back to what matters: quality ingredients, clean flavors, and a little bit of texture contrast. That's it. No drama.
The sesame crisps do the heavy lifting on crunch. The avocado brings the creaminess. The tuna brings everything else.
“Consistent beats perfect — especially on a weeknight.”
What You'll Need
🐟 For the Tuna Tartare
| Ingredient | Amount | Notes |
|---|---|---|
| Sashimi-grade tuna | 200g (7 oz) | Ask your fishmonger directly |
| Ripe avocado | 1 large | Soft but not mushy |
| Soy sauce (low sodium) | 1 tbsp | Or tamari for gluten-free |
| Sesame oil | 1 tsp | Toasted, not plain |
| Fresh lime juice | 1 tbsp | Bottled won't cut it here |
| Sriracha | ½ tsp | Optional, but worth it |
| Fresh ginger (grated) | ½ tsp | Microplane it fine |
| Green onion | 2 stalks, sliced thin | |
| Sesame seeds (black + white) | 1 tbsp | For garnish |
🫙 For the Sesame Crisps
- 6 wonton wrappers (or rice paper rounds)
- 1 tbsp sesame oil
- 1 tbsp mixed sesame seeds
- Pinch of flaky sea salt
How to Make Tuna Tartare with Avocado & Sesame Crisps
Step 1: Make the Crisps First
Preheat your oven to 375°F (190°C).
Brush wonton wrappers lightly with sesame oil. Sprinkle sesame seeds and a pinch of salt on top. Lay them flat on a parchment-lined baking sheet.
Bake 8–10 minutes until golden and crisp. Watch them — they go from perfect to burnt fast.
Set aside to cool. They'll firm up more as they sit.
Step 2: Prep the Tuna
Keep the tuna cold until the last second. Cold fish cuts cleaner.
Dice it into small, even cubes — about ½ inch. Uniform cuts matter here. This isn't the place to rush.
Place in a bowl and add:
- Soy sauce
- Sesame oil
- Lime juice
- Grated ginger
- Sriracha (if using)
Toss gently. Let it sit for 5 minutes max — you're not curing it, just seasoning it.
Step 3: Prep the Avocado
Halve, pit, and dice the avocado the same size as the tuna. Squeeze a little extra lime on top to keep it green.
Don't mash it. You want clean chunks, not guacamole.
Step 4: Assemble
Layer avocado in the base of a bowl or use a ring mold if you want it to look sharp.
Spoon the seasoned tuna on top.
Finish with:
- Sliced green onion
- Sesame seeds
- A tiny drizzle of sesame oil
- Optional: microgreens or thin cucumber slices
Serve immediately with sesame crisps on the side.
Ingredient Swaps & Variations
Real ones know — flexibility is what makes a recipe actually useful.
| Swap This | For This | Why |
|---|---|---|
| Tuna | Salmon (sashimi-grade) | Same process, different flavor |
| Wonton wrappers | Rice crackers | Gluten-free option |
| Soy sauce | Coconut aminos | Lower sodium, slightly sweeter |
| Sriracha | Chili crisp | More texture, more depth |
| Lime juice | Yuzu juice | Elevated citrus note |
Food Safety — Don't Skip This Part
Sashimi-grade tuna is the only tuna for this recipe. Full stop.
Regular grocery store tuna fillets are not the same. Sashimi-grade has been handled and frozen to specific safety standards that make it safe to eat raw.
Ask your fishmonger or check the label. If it doesn't say sashimi-grade or sushi-grade, keep looking.
- Buy it the same day you plan to eat it
- Keep it refrigerated until you're ready to dice
- Don't let the dressed tartare sit for more than 30 minutes before serving
Do the work on this one step. It's worth it.
