Ingredients for the Perfect Tuna Tostadas
Before starting, make sure you have the freshest possible ingredients for the best results.
Sushi-Grade Tuna
The foundation of this dish is sushi-grade tuna—bright, tender, and safe to enjoy raw. Ask your seafood counter for sashimi-quality options, and always look for vibrant color and a gentle, clean scent.
Soy-Sesame Marinade
The marinade infuses the tuna with a combination of soy sauce, sugar, sesame oil, toasted sesame seeds, and green onions. This mixture balances umami, sweetness, and nuttiness for a crave-worthy effect.
Tostada Base
Choose between crispy corn tostadas or make your own by baking grain-free tortillas (such as Siete Cassava) for a gluten- and grain-free option. The crunch is essential for that perfect bite!
Chipotle Aioli
A quick chipotle aioli made by whisking mayonnaise with spicy chipotle powder, fresh lime juice, and a pinch of salt adds a creamy, smoky base flavor to each tostada.
Crispy Shallots
Thinly sliced shallots are fried until golden, adding a restaurant-level finishing touch (and irresistible crunch). They’re simple, quick, and elevate the whole dish.
Avocado & Fresh Herbs
Avocado cut into even chunks brings creaminess, while fresh cilantro leaves garnish with a pop of color and flavor.
Ingredients List
- 8 ounces sushi-grade tuna, chopped into 1-inch pieces
- 1/4 cup soy sauce
- 1 tablespoon sugar
- 2 teaspoons sesame oil
- 1 teaspoon toasted sesame seeds
- 2 green onions, thinly sliced
- 4 tostada chips OR 4 Siete grain-free tortillas
- 1/4 cup mayonnaise
- 1 teaspoon chipotle powder (adjust to taste)
- Juice of 1 lime
- Kosher salt to taste
- 1 shallot, peeled and thinly sliced

Step-By-Step Instructions: How to Make Tuna Tostadas
Follow these steps to prepare your jaw-dropping tuna tostadas with ease.
1. Preparing the Tuna Marinade
- In a small saucepan, combine soy sauce and sugar. Warm gently over medium heat until the sugar dissolves (do not boil), then remove from heat.
- Stir in sesame oil, toasted sesame seeds, and sliced green onions.
- Allow to cool to room temperature, then add the chopped tuna and toss well to coat.
- Cover and marinate for at least 30 minutes in the refrigerator to allow the flavors to develop.
2. Making the Chipotle Aioli
- In a bowl, whisk together mayonnaise, chipotle powder, lime juice, and a pinch of salt.
- Taste and adjust chipotle level for desired spiciness. Set aside.
3. Frying Crispy Shallots
- Thinly slice the shallot (using a mandoline helps for evenness).
- Heat a small pan with about 1/4 inch of olive or avocado oil over medium-high heat.
- Test the heat by dropping in a shallot slice; it should sizzle instantly.
- Fry the shallots in batches, stirring occasionally, until golden throughout.
- Remove with a slotted spoon to a paper towel–lined plate and sprinkle with a bit of salt.
4. Making the Tostada Base
- If using grain-free tortillas, bake on a sheet at 400°F for about 8 minutes until crisp and golden. Cool slightly before assembling.
- If using ready-made tostada shells, set aside for assembly.
5. Assembling Your Tuna Tostadas
- Gently spread a spoonful of chipotle aioli over each cooled tostada base.
- Top with a generous layer of the marinated tuna, followed by cubes of avocado, scattered evenly for a beautiful presentation.
- Sprinkle a handful of crispy shallots and finish with a few fresh cilantro leaves.
Expert Tips for Tostada Success
- Marination Matters: Let the tuna soak in the marinade for a minimum of 30 minutes to develop deep, integrated flavors.
- Shallots Must Be Golden: Don’t walk away when frying—the difference between perfect and burnt is seconds.
- Even Chopping: Cut tuna and avocado in uniform cubes for a balanced bite and prettier presentation.
- Eat Fresh: Tostadas are best served immediately, so assemble just before eating to maintain the crunch.
- Mind the Toppings Order: Layer thoughtfully—aioli, tuna, avocado, then shallots and cilantro—so every flavor and texture shines.
Serving Suggestions & Variations
There are plenty of ways to put your own twist on these tuna tostadas:
- Spicy Upgrade: Add thinly sliced jalapeño or drizzle with sriracha for extra heat.
- More Crunch: Toss in thinly sliced radish or shredded cabbage.
- Alternate Fish: High-quality salmon also works beautifully in place of tuna.
- Vegetarian Version: Try marinated tofu or diced roasted sweet potato instead of fish.
- Herb Options: Swap cilantro for microgreens, chives, or fresh mint for a different aromatic profile.
