Bluefin Tuna Wonton Tostadas Recipe
Introduction
These Bluefin Tuna Wonton Tostadas are a delightful fusion of crisp, savory, and fresh flavors. Perfect as an elegant appetizer or a light snack, they combine tender sushi-grade tuna with crispy wonton wrappers and a flavorful miso-wasabi mayo.
Ingredients
- 10-12 wonton wrappers
- Avocado oil spray
- 1½ tbsp toasted sesame seeds
- 4 nori squares (small and toasted)
- ½ tsp MSG powder
- ½ cup Japanese mayo
- 1½ tsp white miso paste
- 1-1½ tsp real wasabi paste (start with less, this is milder)
- 8 oz sushi-grade bluefin tuna (or sushi-grade tuna of choice)
- 1 lemon (zest only, no juice)
- Chives (to taste)
- Olive oil (to taste)
- Flaky salt (to taste, use sparingly)
Instructions
- Step 1: Preheat your oven to 350℉ (175℃).
- Step 2: Using a knife, cut an “X” in the center of each wonton wrapper to prevent puffing while baking. Arrange them on a foil-lined baking sheet and spray the tops lightly with avocado oil. Bake for 8-12 minutes or until golden and crispy.
- Step 3: While the wrappers bake, finely grind the toasted sesame seeds, nori squares, and MSG powder together using a mortar and pestle or a small food processor.
- Step 4: In a bowl, combine the Japanese mayo, white miso paste, and wasabi paste. Start with ½ teaspoon of wasabi and adjust to taste. Mix until smooth and well combined.
- Step 5: Thinly slice the tuna and arrange the slices side by side on parchment paper. Cover with another sheet of parchment and gently roll over with a rolling pin to thin the fish evenly. Cut the fish into squares that match the size of the wonton tostadas.
- Step 6: Spread the miso-wasabi mayo over each crispy wonton base. Top with a square of sliced tuna, a sprinkle of lemon zest, chopped chives, a drizzle of olive oil, and a very light touch of flaky salt to finish.
Tips & Variations
- Use sushi-grade tuna for the best flavor and safety. If unavailable, other sashimi-grade fish like yellowtail or salmon work well.
- Adjust the wasabi quantity gradually to control the heat level in the mayo.
- For added texture, sprinkle with toasted sesame seeds just before serving.
- Try substituting avocado oil spray with a light olive oil spray if preferred.
Storage
These tostadas are best served fresh for maximum crispiness. If you need to store, keep the tuna topping separate from the wonton shells and assemble just before serving. Store the wrapped tuna in the refrigerator for up to 24 hours. Reheat the wonton shells briefly in the oven if needed to restore crispness.

Serve this delicious recipe with your favorite sides.
FAQs
Can I use other types of fish instead of bluefin tuna?
Yes, you can substitute with any sushi- or sashimi-grade fish like yellowtail, salmon, or albacore tuna. Just ensure the fish is fresh and suitable for raw consumption.
How do I prevent the wonton wrappers from puffing up too much?
Cutting an “X” in the center of each wonton wrapper before baking allows steam to escape, keeping the shell flat and crisp rather than puffed.

Ingredients
Wonton Tostadas
- 10–12 wonton wrappers
- Avocado oil spray
Sesame-Nori Topping
- 1½ tbsp toasted sesame seeds
- 4 small toasted nori squares
- ½ tsp MSG powder
Wasabi-Miso Mayo
- ½ cup Japanese mayo
- 1½ tsp white miso paste
- 1–1½ tsp real wasabi paste (start with ½ tsp and adjust)
Tuna and Garnishes
- 8 oz sushi-grade bluefin tuna (or sushi-grade tuna of choice)
- Zest of 1 lemon (no juice)
- Chives, to taste
- Olive oil, to taste
- Flaky salt, to taste (use very lightly)
Instructions
- Preheat and Prepare Wontons: Preheat your oven to 350℉. Using a knife, make an “X” cut in the middle of each wonton wrapper to prevent puffing while baking. Place the wontons on a foil-lined baking sheet and lightly spray the tops with avocado oil.
- Bake Wonton Tostadas: Bake the prepared wonton wrappers in the preheated oven for 8-12 minutes or until golden and crispy. Remove from oven and let cool.
- Prepare Sesame-Nori Mixture: While the wontons bake, combine the toasted sesame seeds, toasted nori squares, and MSG powder in a mortar and pestle or a small food processor. Pulverize until finely ground to create a crunchy, flavorful topping.
- Make Wasabi-Miso Mayo: In a bowl, mix together the Japanese mayo, white miso paste, and wasabi paste. Start with ½ teaspoon of wasabi and adjust according to heat preference. Stir until fully combined.
- Slice and Thin Tuna: Cut the sushi-grade bluefin tuna into thin slices. Arrange the slices on parchment paper and cover with another piece of parchment. Using a rolling pin, gently roll over the fish to thin and even it out. Then cut the thin fish sheets into squares matching the size of the baked wonton tostadas.
- Assemble Tostadas: Spread a layer of the wasabi-miso mayo evenly on each crispy wonton. Top with a square of the thinly sliced tuna. Sprinkle the lemon zest over the tuna to add bright acidity. Garnish with chopped chives, a drizzle of olive oil, and a very light sprinkle of flaky salt.
Notes
- Make sure to use sushi-grade tuna to ensure freshness and safety when eating the fish raw.
- Adjust the amount of wasabi paste depending on your heat preference; start small and increase gradually.
- Do not skip lemon zest as it adds crucial acidity to balance the richness of the mayo and tuna.
- Use avocado oil spray to keep wontons crispy without adding heavy grease.
- The “X” cut on the wonton wrappers prevents them from puffing up too much in the oven for an even flat tostada base.
- These can be served as an elegant appetizer or as part of a special sushi or seafood spread.
