Coronation Prawn Sandwich

A coronation prawn sandwich takes the familiar British curry-mayonnaise dressing and gives it a lighter seafood focus. Cooked peeled prawns are folded through a creamy mix of mayonnaise, mild curry powder and mango chutney, with lemon and black pepper to sharpen the sweetness and keep the flavour fresh. Served in buttered white bread with crisp iceberg lettuce, it has the soft, creamy texture of a classic sandwich filling with enough crunch to stop it feeling heavy. Best assembled just before eating, it suits a quick lunch, picnic spread or simple afternoon tea plate.

Why this recipe works

  • Fast assembly: Cooked peeled prawns and a simple stirred dressing keep the whole sandwich ready in minutes.
  • Balanced richness: Lemon juice cuts through the mayonnaise and mango chutney, keeping the filling bright rather than heavy.
  • Creamy and crisp: Tender prawns and creamy dressing are balanced by cold iceberg lettuce and soft buttered bread.

Ingredient notes

  • Use well-drained prawns: Pat the prawns dry before mixing so the dressing stays creamy and does not become watery.
  • Keep the curry powder mild: A gentle curry powder suits the sweet mango chutney and lets the prawns remain the main flavour.

Texture tips

  • Protect the bread: Butter the bread evenly and place the lettuce against the filling to help stop moisture soaking into the slices.
  • Fold gently: Mix the prawns into the dressing with a light hand so they stay intact and evenly coated.

Make-ahead tips

  • Assemble just before serving: The prawn mixture can be refrigerated briefly, but keep the bread and lettuce separate until you are ready to eat.
  • Best eaten fresh: This sandwich has the best texture straight after assembly, while the lettuce is still crisp and the bread is soft.

Serving ideas

  • Lunch pairing: Serve with crisps, a simple green salad or cucumber sticks for a classic light lunch.
  • Fresh finish: Add a little extra lemon juice or black pepper just before serving if the filling needs more lift.

  1. In a bowl, whisk together the mayonnaise, mango chutney and curry powder. Squeeze in a little lemon juice and add the black pepper, then taste and adjust with a touch more lemon if you like it brighter.
  2. Add the prawns and gently fold until evenly coated in the coronation-style dressing. Let it sit for 1 minute so the flavours settle.
  3. Butter the bread slices. Layer the iceberg lettuce on one slice, spoon over the coronation prawns, then top with the second slice and press lightly. Serve straight away.

Recipe notes

Tips

  • If your prawns are very cold from the fridge, let them sit at room temperature for 5 minutes before mixing so the dressing coats evenly.
  • For the neatest sandwich, keep the lettuce leaves whole and tuck them in so they form a barrier that helps stop the bread getting soggy.

Substitutions

  • Replace White bread with Brioche bread for a softer, slightly sweeter sandwich.
  • Replace Mango chutney with Orange marmalade for a similar sweet-fruity note with a little bitterness.

Storage

  • Refrigerate up to 1 days
  • Best eaten immediately. If needed, refrigerate the prawn mixture in a sealed container for up to 1 day and assemble the sandwich just before serving.
