What you’ll need
Before diving into the cooking process, here’s a quick rundown of the key ingredients required for this dish:
- 1 lb (450 g) sushi-grade ahi tuna, diced into small cubes
- 4–6 crispy tostada shells (store-bought or homemade)
- 1 ripe avocado, diced
- 1 cup red cabbage, thinly shredded
- 2 tbsp fresh cilantro, chopped (for garnish)
- Juice from 1 lime (reserve a little zest if you like)
- 2 tbsp low-sodium soy sauce
- 1 tsp sesame oil
- 1 tsp rice vinegar
- 1 tsp sriracha or chili garlic sauce (optional)
- 1 small garlic clove, minced
- 1 tsp fresh ginger, grated
- ½ cucumber, thinly sliced
- 1 tbsp sesame seeds or a pinch of togarashi seasoning (for garnish)
- ¼ tsp salt
- ¼ tsp black pepper (adjust to taste)
For a twist, feel free to swap out ingredients where needed; for instance, if you prefer spicy, consider adding a bit more sriracha or trying a different type of fish.
Step-by-step instructions
Now that you have all your ingredients, let’s get into the cooking! Follow these simple steps to create your Ahi Tuna Tostadas:
- Prepare the Marinade: In a medium bowl, whisk together the soy sauce, sesame oil, rice vinegar, lime juice, minced garlic, grated ginger, and sriracha (if you’re feeling adventurous). Add a pinch of salt and pepper to finish.
- Add the Diced Ahi: Gently fold the tuna cubes into the marinade, ensuring each piece is well-coated. Cover and let it chill in the refrigerator for about 10–15 minutes to meld the flavors.
- Prep Your Toppings: While the tuna marinates, shred the red cabbage, dice the avocado (squeeze some lime juice over it to keep it fresh), thinly slice the cucumber, and chop the cilantro.
- Crisp the Tostadas: If you’re making homemade tostadas, lightly brush corn tortillas with oil and bake them at 400°F (200°C) for 8–10 minutes until they’re golden and crunchy. If you’re using store-bought ones, they’re ready to go!
- Build Each Tostada: Start with a layer of shredded cabbage on each tostada to prevent sogginess. Then, spoon the marinated tuna evenly over the cabbage. Top with diced avocado, cucumber slices, and a sprinkle of cilantro.
- Finish and Garnish: Just before serving, layer on sesame seeds or togarashi and add a squeeze of lime for that extra zing. Serve immediately to keep the tostada shells nice and crispy.
How to serve Ahi Tuna Tostadas
These tostadas serve beautifully as an appetizer, but they can also shine as the main course. For added flair, consider arranging them on a vibrant platter with lime wedges and extra cilantro for garnishing. Pair them with a refreshing cucumber salad or a tangy mango salsa to enhance the overall dish.
Storage and reheating tips
If you find yourself with leftovers, it’s best to store the prepared components separately. Keep the marinated tuna, toppings, and tostada shells in airtight containers in the refrigerator. The tuna is best consumed within 24 hours for optimal freshness and safety. When you’re ready to enjoy your leftovers, simply assemble the tostadas again for a quick meal!
