Ingredients You’ll Need
Getting the ingredients right for this dish is both simple and crucial. Each component plays an important role — from the fresh tuna providing the main flavor and texture, to the crispy wonton chips that add a satisfying crunch and the creamy avocado that smooths everything out.
- 8 oz sushi-grade tuna: The foundation of this tartare, fresh and diced to perfection for tender bites.
- 1 ripe avocado: Adds creamy richness that balances the spice and zestiness.
- 2 green onions (green parts only): Provides a mild onion flavor and a pop of green color.
- 2 tbsp low-sodium soy sauce: Gives a salty umami kick without overpowering the delicate fish.
- 1 tbsp Sriracha sauce: Delivers the spicy punch that makes this recipe exciting; adjust amount to taste.
- 12 crispy wonton chips: Serve as a crunchy base to scoop up the tender tartare.
- 1 tbsp toasted sesame seeds: Sprinkled on top for an extra nutty crunch and visual appeal.
- Microgreens or cilantro: A fresh, herbal garnish that brightens the finished dish.
How to Make Spicy Tuna Tartare on Crispy Wonton Chips Recipe
Step 1: Prepare the Wonton Chips
Start by preheating your oven to 350°F (175°C). Use store-bought wonton wrappers cut into triangles or ready-made chips, and bake them until golden brown for about 5 to 7 minutes. This step ensures you get perfectly crispy chips that hold up well under the tartare.
Step 2: Mix Tuna
Gently combine your diced sushi-grade tuna with low-sodium soy sauce and Sriracha in a bowl. Stir just enough to coat the tuna evenly without breaking down its tender texture. This spicy mix is the heart of the tartare flavor profile.
Step 3: Add Avocado
Carefully fold the diced avocado into the tuna mixture. Take your time here to maintain the creamy chunks of avocado; this adds a wonderful silky texture contrast to the dish.
Step 4: Garnish the Mixture
Sprinkle finely chopped green onions and toasted sesame seeds over the tuna and avocado mix. These toppings lend extra flavor layers and a striking presentation that will impress your guests.
Step 5: Serve on Crispy Wonton Chips
Just before serving, scoop generous spoonfuls of the spicy tuna tartare onto each crispy wonton chip. The warmth of the chips and the coolness of the tartare creates an irresistible duo that will disappear fast.

Side Dishes
This Spicy Tuna Tartare on Crispy Wonton Chips Recipe stands out on its own but pairs wonderfully with light sides such as a crisp cucumber salad, pickled ginger, or even a refreshing seaweed salad. These sides complement the main dish without stealing the spotlight.
Creative Ways to Present
For a party, arrange the wonton chips on a large platter with the tartare mixture in a beautiful bowl at the center, letting guests build their own bites. Alternatively, you can serve the tartare in small individual spoons topped with a chip for an elegant hors d’oeuvre presentation.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, store the spicy tuna and avocado mixture separately in an airtight container in the refrigerator. The tuna tartare is best eaten within 24 hours to ensure freshness and safety.
Freezing
Freezing is not recommended for this recipe because the texture of fresh tuna and avocado can be compromised. The avocado may become mushy and the tuna can lose its fresh, delicate texture after thawing.
Reheating
This dish is designed to be enjoyed cold and fresh. Reheating is not advised as it will affect the texture and flavor balance that makes this Spicy Tuna Tartare on Crispy Wonton Chips Recipe so delightful.
FAQs
Can I use tuna other than sushi-grade for this recipe?
For safety and flavor, it’s best to use sushi-grade tuna, as this dish is served raw. Using other types may risk bacteria and won’t deliver the fresh, clean taste that makes this tartare shine.
What can I substitute for wonton chips?
If wonton chips aren’t available, try crisp pita chips or thin crackers. Just make sure they are sturdy enough to hold the tartare without breaking apart.
How can I adjust the spice level?
Sriracha is adjustable to your taste — start with less and add more if you want extra heat. You can also swap it for a milder chili sauce or add a dash of chili flakes for a different kind of kick.
Is it okay to prepare the tartare ahead of time?
You can prepare the tuna mixture a few hours ahead, but fold in the avocado only right before serving to keep it from browning and losing texture.
What are some alternative garnishes?
Try finely sliced radishes for crunch, a sprinkle of chives for mild onion flavor, or even a drizzle of spicy mayo to add a creamy, tangy twist on the classic presentation.
