What is prawn cocktail?
Prawn cocktail is a familiar British starter: prawns are served with a creamy, tangy Marie Rose sauce, often alongside lettuce and lemon. This version keeps the classic combination and layers it in glasses for easy serving.
The quick method relies on cooked prawns and a sauce stirred together by hand, so there is no cooking to do. The contrast between cool, crisp lettuce and the rich sauce makes each layer count.

The prawns provide most of the protein, while mayonnaise is the main source of fat and ketchup contributes carbohydrates. For a more substantial plate, serve a portion with extra salad or bread alongside.
The Marie Rose sauce
Mayonnaise: It gives the sauce its creamy body, while ketchup brings sweetness and a tomato flavour. Lemon juice and Worcestershire sauce sharpen the mixture.
Seasoning: Paprika keeps the flavour gentle, while cayenne gives it more heat. Add the cognac or brandy only if you want that optional extra, and adjust salt and pepper to taste.
Layering the glasses
Lettuce first: Divide the leaves between the glasses, then add sauce around the edges as directed. Repeating the layers gives the servings a striped look and spreads the sauce through the salad.
Prawns last: Coat the cooked prawns in the remaining sauce before spooning them into the glasses. This keeps the main prawn mixture together rather than mixing all the lettuce into it.
Choosing and preparing the prawns
Cooked king prawns: They are ready to use, so fold them into the sauce rather than cooking them again. Handle them gently to keep their shape.
Crevettes: These whole, unpeeled prawns are an optional finishing touch. Set one on each serving if you want a more decorative presentation.
Balancing flavour and texture
Crisp leaves: Use fresh lettuce and keep it separate from the sauce until you assemble the glasses. That helps the leaves retain their texture.
Bright garnish: Cherry tomatoes add a fresh contrast, and lemon slices make the servings easy to finish with a squeeze of citrus. A light dusting of paprika completes the top.
Serving ideas
As a starter: The recipe makes four servings in glasses, ready to serve straight after assembly. For a more substantial light lunch, the description suggests sharing the recipe between two.
As appetisers: Make smaller portions for party food and serve them in small glasses or dishes. Keep the same layers, adjusting the amount in each serving.
Recipe notes & tips
- Taste the sauce after adding the lemon juice and adjust the seasoning before assembling.
- Choose paprika for a milder flavour or cayenne for more heat.
- Keep some lettuce leaves aside for the top layer.
- Coat the prawns evenly in the remaining sauce before dividing them between the glasses.
- Add the lemon and tomatoes just before serving for a fresh finish.
Variations
- More heat: Use cayenne instead of paprika for a spicier sauce.
- Milder sauce: Choose paprika and leave out the optional cognac or brandy.
- Extra citrus: Serve with additional lemon slices for squeezing at the table.
- Party portions: Divide the layers among smaller glasses or dishes for appetisers.
- Decorative finish: Top each glass with a whole, unpeeled crevette.
Common mistakes to avoid
- Over-seasoning the sauce: Add salt, pepper and Worcestershire sauce gradually, then taste before serving.
- Using too much cayenne: Start with the stated pinch and add more only if you want extra heat.
- Mixing the lettuce into the prawn sauce: Keep the leaves in layers so they retain their separate texture.
- Skipping the lemon: Include the juice in the sauce and keep the slices for serving to balance its richness.
- Forgetting the garnish: Divide the 8 cherry tomatoes between the four servings, with 2 on each.
