Prawns-Salad Tostadas with Tomatoes and Cucumber

This vibrant prawn salad tostada recipe is a fresh and zingy addition to your high-protein repertoire. Combining succulent prawns with crisp cucumber, ripened tomatoes, and a hit of serrano chilli, it offers a wonderful balance of textures and heat. The seafood is gently poached to maintain a delicate bite, then tossed in a bright lime and coriander dressing that keeps the dish light and refreshing. It is an ideal choice for a sophisticated weekend lunch or a colourful sharing platter for a garden gathering.

While this dish is naturally nutritious, the addition of creamy guacamole and a drizzle of soured cream provides a satisfying richness. You can use shop-bought tostada shells for a quick midweek meal, or fry your own corn tortillas for an authentic, extra-crunchy base. Prepared prawn salad can be kept chilled for up to a day, making it an excellent option for stress-free entertaining. Simply assemble just before serving to ensure the tostadas stay perfectly crisp.

  • 3–4 serrano chillies, stemmed, seeded, deveined, finely chopped

  • 160ml fresh lime juice

  • 1/2 cup coarsely chopped fresh coriander

  • 24 small corn tortillas or store-bought crispy tostada shells

  • Vegetable oil (for frying

  • if needed)

  • A candy or deep-fry thermometer

Fill a large bowl with 2400ml cool water; stir in 60ml salt (it should taste like seawater). Add prawns and soak 30 minutes, then drain.

Fill a medium pot with 1925ml water; stir in 60ml salt. Bring to a boil, add prawns, and immediately turn off heat. Let sit until pink, opaque, and barely cooked through, about 3 minutes. Drain, transfer to a large bowl, and let cool.

Add tomato, onion, cucumber, chillies, lime juice, and coriander to prawns. Season with salt. Chill until ready to use.

If frying tortillas, fit a large skillet with candy or deep-fry thermometer; pour in oil to measure 1". Heat over medium-high until thermometer registers 191°C. Fry tortillas in batches until crispy, turning every 30 seconds, about 2 minutes total. Drain on paper towel-lined baking sheets and season with salt.

Spread 1 heaping Tbsp. Hold-the-Lime Guacamole on a tostada shell. Top with 1/4 cup prawns salad, then lettuce, crema, queso fresco, and salsa. Repeat with remaining tostada shells. Serve at room temperature.

Prawns salad can be chilled for up to 1 day. Bring to room temperature before serving.
