Creamy, garlicky, lemon-infused prawns with ripe avocado piled onto crispy toasted bread make this Prawn Crostini the kind of bite that works just as well for lunch as it does for entertaining. The contrast between the crunchy base and the cool, fresh topping keeps every mouthful balanced, which is exactly what makes prawn and avocado such a timeless pairing.

It also fits beautifully alongside dishes like Lemon Garlic Butter Chicken, where those same buttery and garlicky notes tie everything together. If you love prawn and avocado recipes that feel light but still special, this prawn and avocado crostini brings an elegant seafood touch without feeling over the top.

What Makes This Recipe So Good

This Prawn Crostini works because it treats the prawns like the star instead of burying them under heavy toppings. A quick garlic and lemon sauté keeps the prawns juicy and bright, while the avocado adds just enough creaminess to soften the sharp edges, which is what makes prawn and avocado such a reliable pairing when you want something that feels fresh but still indulgent.

It also hits that sweet spot between impressive and easy. You get all the elegance of prawn and avocado crostini without complicated steps or fussy plating.

This prawn and avocado crostini keeps things simple on purpose, so each ingredient earns its place. You are not building layers of random toppings here.

  • King Prawns: These give Prawn Crostini its bold, juicy centre, delivering that sweet seafood bite that stands up to garlic and lemon without getting lost.
  • Garlic Olive Oil: Using garlic-infused oil builds deep flavor right from the pan, letting the prawns pick up that savoury backbone without needing extra butter or heavy sauces.
  • Ripe Avocado: This adds natural creaminess that softens the sharp lemon and garlic, which is why prawn and avocado recipes feel so luxurious without being heavy.
  • Crusty Ciabatta or Sourdough: A firm, airy bread gives you the crunch that holds everything together, keeping the prawn and avocado crostini crisp underneath while the toppings stay fresh on top.

Note: Please see recipe card at the bottom for a full list of ingredients with measurements.

How To Make Prawn Crostini

Preheat your grill or broiler to medium high, arrange the bread slices on a lightly greased tray, and toast until golden and crisp.
  1. Toast the Bread: Preheat your grill or broiler to medium high, arrange the bread slices on a lightly greased tray, and toast until golden and crisp before setting them aside to cool slightly.
 In a bowl, toss the prawns with garlic, paprika, and lemon juice.
  1. Season the Prawns: In a bowl, toss the prawns with garlic, paprika, and lemon juice until evenly coated, then lightly season with salt to bring out their natural sweetness.
Heat the garlic olive oil in a wide skillet over medium high, add the prawns and cook.
  1. Sauté the Prawns: Heat the garlic olive oil in a wide skillet over medium high, add the prawns, and cook for a few minutes until just starting to turn pink.
Lower the heat, sprinkle in the parsley.
  1. Finish with Parsley: Lower the heat, sprinkle in the parsley, and let the prawns gently finish cooking until they are juicy, glossy, and fully opaque.

  1. Mix the Avocado Salad: Combine the avocado, tomato, lemon juice, and salt in a bowl, stirring gently so the avocado stays creamy but not mashed.
Fold the warm prawns through the avocado mixture, then spoon everything generously over the toasted bread.
  1. Assemble the Crostini: Fold the warm prawns through the avocado mixture, then spoon everything generously over the toasted bread and serve right away.

This Prawn Crostini pairs especially well with dishes that bring warmth and texture to the table without stealing attention from the fresh prawn and avocado topping. Try serving it with Zuppa Toscana for a cozy, savoury soup option, Crispy Parmesan Asparagus with Garlic Butter to add a bright and crunchy vegetable side, and Moist Cornbread for something soft and slightly sweet to round out the plate.

Tips For Making Garlic Prawn Crostini

  • Use prawns that are as dry as possible before cooking so they sear instead of steaming, which keeps them juicy and lightly golden instead of watery.
  • Toast the bread until it is properly crisp because the prawn and avocado topping is moist and you want a base that can hold everything without going soggy.
  • Add the warm prawns to the avocado just before serving so the heat softens it slightly but does not turn it into mash.
  • If your avocado is very ripe, fold gently with a spoon instead of stirring so you keep creamy chunks instead of a paste.

Recipe FAQ’s

How Do I Keep The Bread From Going Soggy?

Make sure the bread is well toasted and fully cooled before adding the topping. Spreading a very thin layer of olive oil on the toast also creates a light barrier that helps keep it crisp longer.

Can I Make These For A Party Table That Sits Out?

You can keep the toasted bread and prawn mixture separate and assemble just before serving. This way, the crostini stay crunchy and the prawn and avocado topping stays fresh and bright.

How Do I Keep The Avocado From Browning?

The lemon juice helps slow oxidation, but covering the bowl tightly with plastic wrap pressed directly onto the surface also makes a big difference if you need to wait a little before serving.

    Is the avacado salad savable? If there was leftover would it save well?
