Classic Prawn Cocktail – Easy, Delicious & Impressive
This prawn cocktail is a classic starter that has stood the test of time — it’s fresh, simple, and always feels a little special. This version is easy to prepare, requires no cooking, and can be assembled ahead of time, making it perfect for entertaining, especially at Christmas.
I’ve kept it simple and traditional with crisp cos lettuce, sweet tomatoes, avocado and a homemade prawn cocktail sauce. You can easily make it your own if you wish. For an extra little kick, a spoonful of my homemade chilli jam stirred through the sauce is absolutely delicious.

- ½ – 1 tsp lemon juice to taste
- ½ – 1 tsp Worcestershire sauce to taste

Instructions
Prepare the prawns
- Peel the prawns and remove the tails and heads. Remove the vein by gently pulling it out from the back.
- Refrigerate the peeled prawns while you prepare the other ingredients.
Prepare the vegetables
- Cos lettuce: Trim off the ends and shred. You’ll need enough to fill at least half of each glass or bowl.
- Tomatoes: Cut into quarters or halves so they’re bite-sized.
- Avocado: Dice just before serving. Toss gently with a squeeze of lemon juice to prevent browning.
- Finely chop the parsley, if using.
Make the cocktail sauce
- In a bowl, whisk together the cream, tomato ketchup and mayonnaise.
- Season with lemon juice and Worcestershire sauce to taste.
- Add a few drops of Tabasco or a pinch of cayenne if you like a little kick.
- Adjust seasoning — the sauce should be creamy, tangy and well balanced.
- Refrigerate until needed.
Assemble the prawn cocktails
- You can use martini glasses, small bowls, tumbler-style glasses, wine glasses or any attractive serving vessels.
- Place shredded cos lettuce into each glass so it comes up at least halfway.
- Add a small layer of tomatoes.
- Spoon over some avocado.
- Reserve one good-looking prawn per serve for garnish.
- Pile the remaining prawns generously on top. If any are very large, cut them in half so they’re easy to eat with a fork.
- Spoon a little cocktail sauce over the prawns, allowing the layers underneath to remain visible.
- Garnish with the reserved prawn and a light sprinkle of parsley.
To serve
- Serve with lemon wedges and extra cocktail sauce on the table so guests can add more if they wish. For best results, the prawn cocktails are nicest served very well chilled — once assembled, refrigerate for about 1 hour before serving so everything is properly cold and refreshing.
