If you’re a fan of seafood and you like a bit of spice, this dinner is perfect. Plus it’s so quick to pull together too!

I love cooking with ready-peeled king prawns. No need to get into chopping up and trimming meat – each prawn is the perfect bite-size portion!

Prawns cook so quickly – which means we can start off putting the pasta on to boil, and the rest of the recipe comes together while the pasta is cooking. I chop up the pepper, onion and jalapeno once the pasta is already on, so there’s hardly any up-front prep time.

📋 What ingredients do we need?

Ingredients for Cajun prawn linguine on a wooden board.
  • King prawns or shrimp – de-shelled and de-veined
  • Linguine – or swap for spaghetti, tagliatelle or your favourite pasta shape
  • Red bell pepper, onions, Jalapeno and garlic for colour, flavour and crunch
  • Hot pepper sauce – I use Franks hot sauce for the perfect Buffalo-style tangy heat. You can replace with another hot sauce – such as sriracha if you like (i’d start with 1 tbsp sriracha and add more in if needed later)
  • Worcestershire sauce and cider vinegar – it adds extra flavour and tanginess – which balances perfectly with the cream
  • Cream and parmesan – for creamy cheesy goodness

👩‍🍳PRO TIP Be sure to save some of the water from cooking the pasta. We add splashes of this water in at the end to make extra sauce. The starchiness of the water makes the sauce cling to the pasta.

🍽️ What to serve it with

I find this to be a nice filling meal, so I usually just serve it by itself, but if you wanted a little extra, try serving with:

You can adjust the 🌶 spice level to your liking. If you don’t like it too hot, just go with one tablespoon of hot sauce and leave out the jalapeno. The cider vinegar and Worcestershire sauce still provides a lovely tang that compliments the cream and parmesan in the sauce.

  • Cook the linguine in a large pan of boiling salted water, as per the pack instructions.
    300 g (10.5 oz) dried linguine
  • Once cooked, drain, reserving half a cup of the pasta cooking water.
  • Meanwhile, heat the oil in a large frying pan (large skillet), over a medium heat.
    2 tbsp oil
  • Add the onion, red pepper, jalapeno, and garlic, and fry for 5 minutes, stirring often, until the onion starts to soften.
    1 small onion, 1 red bell pepper, 1 jalapeno, 2 cloves garlic
  • Add the prawns to the pan and sprinkle the Cajun seasoning on top. Stir together and fry for a further 2 minutes, until they’re just starting to turn pink.
    300 g (10.5 oz) king raw king prawns, 1 tbsp Cajun seasoning
  • Add the hot pepper sauce, cider vinegar, Worcestershire sauce, and cream.
    3 tbsp hot pepper sauce, 1 tbsp cider vinegar, 1 tbsp Worcestershire sauce, 120 ml (1/2 cup) double cream (heavy cream)
  • Stir together and bring to a gentle simmer, then stir in the parmesan.
    75 g (3/4 cup) grated parmesan
  • By now the linguine should be ready. Add to the pan, along with a a good splash (about 4-6 tablespoons) of the pasta cooking water.
  • Stir together, using a set of tongs, until the linguine is coated in the sauce. Add more pasta cooking water if you want to loosen it up further.
  • Turn off the heat and divide between bowls. Top with grated parmesan, black pepper, and parsley before serving.
    grated parmesan, black pepper, finely chopped curly parsley



Can I make it ahead and/or freeze it?
I don’t recommend making this dish ahead. Linguine doesn’t reheat well, and there’s a risk of the prawns becoming rubbery upon reheating.
Ingredient swaps
  • Swap the linguine for spaghetti, tagliatelle or your favourite short pasta
  • Swap the prawns for small chunks of white fish or salmon (they will take a little longer to cook than prawns, so please do ensure they’re fully cooked).
  • This dish can easily take an extra couple of vegetables. Peas, courgette and mangetout work great.
  • Fancy a chicken version?  Try my Buffalo Chicken Pasta.

    We substituted chicken for the prawns and swapped out the creme for a reduced fat creme fraiche to make a lighter version and it was absolutely delicious. A nice warming heat.
