Ingredients

Scale
  • 4 large corn tortillas
  • Vegetable oil (for frying or brushing if baking)
  • 8 oz (225g) sushi-grade tuna steak, about 1 inch thick
  • 2 tbsp sesame seeds (black and white mix recommended)
  • Salt and freshly ground black pepper, to taste
  • 1 tbsp neutral oil (grapeseed or avocado oil) for searing
  • 1 large ripe avocado
  • 1 tbsp fresh lime juice
  • 2 tbsp sour cream or crème fraîche (Greek yogurt as substitute)
  • Salt, to taste
  • 1 tbsp finely chopped fresh herbs (chives or cilantro, optional)
  • Microgreens or thinly sliced radishes (for garnish)
  • Soy sauce or ponzu (for drizzling)
  • Pickled ginger or thinly sliced cucumber (optional garnish)

Instructions

  1. Prepare the Tostada Shells: Heat about 1 inch of vegetable oil in a deep frying pan over medium-high heat until it reaches 350°F (175°C) or a small piece of tortilla sizzles immediately. Fry each corn tortilla one at a time, flipping after 30 seconds until golden and crisp—about 1 minute per side. Drain on paper towels and season lightly with salt. Alternatively, brush tortillas lightly with oil and bake at 400°F (200°C) for 8-10 minutes, flipping halfway.
  2. Make the Avocado Mousse: In a small blender or food processor, combine the ripe avocado, lime juice, sour cream or crème fraîche, salt, and herbs if using. Blend until smooth and creamy. Taste and adjust salt or lime juice if needed. Transfer to a bowl and refrigerate while prepping the tuna.
  3. Prepare and Sear the Tuna: Pat the tuna steak dry with paper towels. Season both sides with salt and pepper. Spread sesame seeds on a plate and press the tuna into the seeds to coat evenly. Heat 1 tablespoon of neutral oil in a hot skillet over medium-high heat until shimmering. Sear the tuna for 45 seconds to 1 minute per side for rare, or longer if preferred. Remove from heat and let rest for 5 minutes before slicing thinly against the grain.
  4. Assemble the Tostadas: Spread a generous layer of avocado mousse on each tostada shell. Top with a few slices of seared tuna. Garnish with microgreens, radish slices, or pickled ginger. Drizzle lightly with soy sauce or ponzu.

Notes

[‘Do not skip the sesame seed crust for added texture and flavor.’, ‘Use a very hot pan to sear the tuna quickly to keep the inside rare and tender.’, ‘Ensure avocado is ripe but not overripe for best mousse texture.’, ‘Fry tostadas just until golden to avoid greasiness.’, ‘Slice tuna thinly for balanced texture with the tostada and mousse.’, ‘Rest tuna before slicing to keep juices locked in.’, ‘Avocado mousse can be made up to 6 hours ahead; cover tightly with plastic wrap pressed on surface to prevent browning.’, ‘Tostadas are best fried or baked just before serving to maintain crunch.’, ‘Leftover tuna can be refrigerated up to 1 day; store separately from tostadas to avoid sogginess.’]
