Prawn and Fennel Salad Ingredients: What You'll Need

Getting your mise en place ready for this easy seafood salad recipe is half the fun. You've got sweet prawns (or shrimp) meeting the crisp, subtle anise crunch of fresh fennel bulb, peppery watercress, and a punchy Dijon-lemon dressing that ties this Mediterranean salad together.

Step 1: How to Cook Prawns for Salad

Bringing your prawns to tender, pink perfection is all about speed and timing. Don't overcook them, or you'll miss that juicy bite!

Drop your raw prawns into a boiling saucepan of water, return to a boil, and simmer for just 2 minutes until they turn pink and cooked through. If your pan isn't large enough to fit them all in a single layer, cook them in 2–3 batches, letting the water return to a full boil between each one - this keeps every prawn cooking evenly rather than some turning rubbery while others stay underdone. Drain them, cool them down, pat them dry with paper towels, and slice them cleanly in half lengthways before tossing them into your main serving bowl.

Ingredients

  • 1.25 kg raw large prawns (shrimp), tails removed. Plump succulent shellfish, cleaned and prepared to cook up tender and sweet. (See the ⚠️ Don't skip this section at the bottom of this card)
  • 1 large fennel bulb, thinly sliced (400 g) Crisp, pale green bulb offering a subtle aniseed crunch and refreshing bite.
  • 300 g watercress: Peppery, vibrant dark green leaves providing a crisp, earthy freshness to balance the rich seafood.
  • 2 tbsp finely chopped chives: Delicate, mild onion-flavored green shoots adding a subtle, elegant herbaceous finish.
  • 125 ml extra virgin olive oil: Premium, fruity cold-pressed oil to tie the dressing together with rich, velvety depth.
  • 1 tablespoon Dijon mustard: Sharp, tangy French mustard acting as an essential emulsifier with a clean, spicy kick.
  • Fresh lemon juice, to taste - Bright, zesty acidity that lifts the dressing and cuts through the richness of the oil.
  • 1 large garlic clove, finely chopped: Pungent, aromatic allium delivering a warm, savory punch to the dressing.
  • Salt and cracked black pepper, to season: Coarse seasonings added meticulously to elevate and harmonize every underlying flavour.

  • How to Make It: Instructions

    Cooking the Prawns

    1. Bring a large saucepan of water to the boil. If your prawns won't fit in a single layer, cook them in 2–3 batches rather than all at once - overcrowding the pan drops the water temperature and cooks the prawns unevenly. 

    2. Drain and leave to cool. Pat the prawns dry with paper towels and slice in half lengthways. Place in a large serving bowl.

    Building the Salad

    1. Add the fennel, watercress and chives to the bowl and mix well.

    Dressing & Serving

    1. To make the dressing, whisk the oil, lemon juice, mustard and garlic together until combined.

    2. Pour the dressing over the salad, season with salt and cracked black pepper and toss gently. Arrange the salad on serving plates and serve immediately.
⚠️ Don't skip this
Cook the prawns in batches if needed. Adding too many at once cools the water down, so the prawns simmer instead of boil - you'll end up with some pieces undercooked and others overcooked by the time they're all done. Also, pat the prawns completely dry before slicing and adding them to the bowl - any lingering water will water down the dressing and leave you with a soggy salad instead of a crisp, punchy one.

Who says a salad can't steal the show? This prawn and fennel salad recipe proves that a handful of fresh, honest ingredients tossed together with a little care can taste every bit as impressive as something far more fussy.

Prawn and Fennel Salad FAQs

Can I use cooked prawns instead of raw?

Yes - if your prawns are already cooked, skip the boiling step entirely. Just pat them dry, slice them in half lengthways, and toss them straight into the bowl with the fennel and watercress before dressing. This also makes for an even quicker version of the salad.

Do I need to cook the prawns in batches?

Only if your pan is on the smaller side. 1.25 kg of prawns is a lot to fit in a single layer, so if they'd be piled on top of each other, cook them in 2–3 batches instead. This keeps the water at a strong boil throughout, so every prawn cooks evenly in the full 2 minutes rather than some staying underdone while others overcook.

What can I substitute for fennel in this salad?

If fennel isn't your thing or you can't find it, thinly sliced celery gives a similar crisp bite, though you'll lose the subtle anise flavour. Sliced radish or cucumber also work well if you want something cool and crunchy instead.

Can I make this prawn salad ahead of time?

The prawns can be cooked, cooled, and refrigerated up to a day in advance. However, hold off on slicing the fennel and dressing the salad until just before serving, since watercress wilts quickly and fennel loses its crunch once cut and dressed.

Is this prawn and fennel salad gluten-free?

Yes, this salad is naturally gluten-free as written. Just double check your Dijon mustard label, since some brands add wheat-based thickeners, though most are safe.

Pro Tips for the Best Prawn and Fennel Salad

  • Don't overcook the prawns - Two minutes is all it takes. Pull them the moment they turn pink and curl; a few extra seconds in the water and they'll turn rubbery.
  • Cook in batches for even results - Don't crowd the pan. If the prawns can't sit in a single layer, do 2–3 smaller batches so each one gets a proper rolling boil.
  • Slice the fennel thin - Use a mandoline or a very sharp knife so the fennel stays delicate rather than woody, and dress with any fronds still attached for extra flavour.
  • Dress at the last minute - Watercress is delicate and wilts fast once dressed, so toss everything together right before it hits the table.
  • Chill your serving bowl - A cold bowl helps keep the prawns and watercress crisp for longer, especially if you're serving outdoors on a warm day.
