This classic prawn cocktail sauce brings back the timeless flavor of seafood houses with a perfect balance of tangy and creamy. I’ve refined this recipe over years of testing to capture that signature taste.
The base is simple: quality mayonnaise blended with ketchup for sweetness and a touch of horseradish for a subtle kick. A squeeze of lemon juice brightens the sauce, while Worcestershire adds depth.
What you get is a smooth, tangy dip that complements prawns without overpowering them. It clings beautifully to every bite, delivering consistent flavor in every spoonful.
Make a batch ahead—it keeps well in the fridge for up to a week, and the flavors only improve with time.
Ingredients for Prawn Cocktail Sauce Recipe Mayonnaise
Eight ingredients blend into that nostalgic seafood house dip you love.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥄 | 1 cup | Full-fat for creaminess |
| Ketchup 🍅 | ½ cup | Quality brand preferred |
| Prepared Horseradish 🌿 | 2 tbsp | Adjust for heat preference |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed preferred |
| Worcestershire Sauce 💧 | 1 tsp | Adds umami depth |
| Hot Sauce 🔥 | ½ tsp | Optional, for extra kick |
| Salt 🧂 | ¼ tsp | Fine grain preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
The mayonnaise is non-negotiable here—Duke’s or Hellmann’s give you that classic creamy base. Most grocery stores carry them, but if you’re feeling fancy, Whole Foods has some excellent organic options. Horseradish can be found in the condiment aisle, usually near the mustards. Look for the refrigerated kind if you can—it’s got more bite than the shelf-stable version.
No horseradish? A pinch of cayenne or extra hot sauce works in a pinch. Out of Worcestershire? A splash of soy sauce with a dash of lemon can mimic the savory depth (just go light). Fresh lemon juice is ideal, but the bottled stuff is fine too—just don’t skip it entirely. The ketchup can be swapped for chili sauce if you want a slightly sweeter, spicier twist.
This keeps beautifully. Store in an airtight container in the fridge for up to 1 week. The flavors actually get better after a day or two, so making it ahead is a win. If you’ve got leftovers after 5 days, it’s still safe but best used soon after.

Step-by-Step Instructions for Prawn Cocktail Sauce with Mayonnaise
Here’s the method. Straightforward, tested, works every time.
Step 1: Combine the Base Ingredients
In a medium bowl, add the 1 cup Mayonnaise and 0.5 cup Ketchup. I like to start with these two as the foundation—they create that classic creamy-tangy base that defines this sauce.
Whisk them together until fully combined and smooth. You shouldn’t see any streaks of ketchup in the mayonnaise. This blending step is important because it ensures even distribution of flavors throughout the sauce.
Step 2: Add the Bold Flavors
Next, stir in the 2 tbsp Prepared Horseradish, 1 tbsp Lemon Juice, and 1 tsp Worcestershire Sauce. The horseradish adds that signature sharp kick, while the lemon juice brightens everything up.
The Worcestershire sauce might seem like a small addition, but it adds a deep umami richness that balances the other flavors perfectly. Mix well after each addition so everything incorporates evenly.
Step 3: Season and Adjust to Taste
Now, add the 0.5 tsp Hot Sauce, 0.25 tsp Salt, and 0.25 tsp Black Pepper. The hot sauce gives an extra layer of heat, but feel free to adjust if you prefer a milder or spicier result.
Taste and adjust the seasoning as needed. If it needs more tang, add a bit more lemon juice. If it’s too thick, thin it slightly with a splash of water or more lemon juice. The sauce should be thick enough to cling to prawns but still easy to dip into.
Step 4: Chill and Let Flavors Meld
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes. This resting time allows all the flavors to meld together and the sauce to thicken slightly.
I always make this sauce ahead of time if possible—it tastes even better after sitting for a few hours. Give it a quick stir before serving to ensure everything is well combined.
Pro Tips For Making Prawn Cocktail Sauce Recipe Mayonnaise
- Chill the Sauce: After mixing, refrigerate the sauce for at least 30 minutes—this lets the flavors meld and mutes the sharpness of the horseradish and lemon juice.
- Use Full-Fat Mayo: Skip the light mayo; full-fat gives the sauce a richer texture that clings to the prawns instead of sliding off.
- Add Horseradish Last: I learned this the hard way—mix in the horseradish at the very end so its potency doesn’t fade as the sauce sits.
- Balance with Lemon: If the sauce tastes too sweet from the ketchup, a squeeze of fresh lemon juice—about 1 teaspoon at a time—actually changes the outcome.
