Cajun prawn pasta

Cajun Prawn Pasta

This is one of those dinners that feels like you’ve cheated the system. Creamy, spicy, silky pasta loaded with juicy king prawns, built from a handful of ingredients, and on the table in 20 minutes. No complicated prep, no long simmer, just bold flavour and proper comfort in a bowl.

Cajun prawn pasta sits in that sweet spot between cosy and punchy. You’ve got sweetness from the prawns, heat and smokiness from the Cajun spice, richness from the cream cheese and parmesan, and just enough tomato paste to give depth and colour. It tastes layered, but it’s actually very straightforward.

The sauce isn’t heavy double cream territory. It’s lighter, silkier, and clings beautifully to the pasta without drowning it. The starch from the pasta water pulls everything together, creating that glossy finish that makes it feel restaurant level without the restaurant effort.

This is the sort of meal you make midweek when you want something comforting but not sluggish. It’s quick, it’s bold, and it looks impressive without requiring any heroics.

Minimal ingredients. Maximum flavour. Exactly how quick pasta should behave.

Why this pasta works so well

Cajun spice does most of the heavy lifting. It brings heat, smokiness, garlic, herbs and depth in one hit. That means you don’t need a long ingredient list to build flavour.

Tomato paste adds concentration and richness. It deepens the sauce without making it taste like a tomato pasta. It’s subtle, but important.

Cream cheese is the shortcut to a creamy sauce without needing loads of cream. It melts into the stock and creates a velvety texture while keeping things balanced rather than overly rich.

Vegetable stock adds savoury backbone and loosens everything just enough to coat the pasta properly.

King prawns cook quickly and stay tender if you don’t overdo them. They bring sweetness and protein while keeping the dish feeling light.

And the pasta water is your secret weapon. That starch helps emulsify the sauce, giving you that glossy, clingy finish that makes every forkful creamy rather than watery.

It’s bold, creamy, slightly spicy, and perfectly balanced.

Equipment you’ll need

A large saucepan for cooking the pasta.

A wide frying pan for building the sauce and finishing everything together.

Simple kit. Big results.

Ingredients

200 g pasta, linguine works brilliantly
1 onion, diced
1 tbsp tomato paste
1 tbsp Cajun spice
200 g king prawns
175 ml vegetable stock
40 g cream cheese
20 g parmesan, grated, plus extra for serving
10 g parsley, chopped
Salt and black pepper
Cooking oil

How to make it

Cook the pasta in salted boiling water according to the packet instructions. Make sure the water is properly salted. It should taste like the sea.

While the pasta cooks, heat a drizzle of cooking oil in a large frying pan over a medium to high heat.

Add the diced onion and cook for about 5 minutes until softened and lightly golden.

Stir in the tomato paste and Cajun spice. Cook for about 30 seconds to toast the spices and deepen the flavour.

Add the king prawns and cook for around 2 minutes, stirring occasionally, until they turn pink and opaque. Don’t overcook them or they’ll turn rubbery.

Pour in the vegetable stock and add the cream cheese. Stir well and bring to a gentle simmer. The cream cheese will melt and create a smooth sauce.

Drain the pasta, reserving a splash of pasta water.

Add the cooked pasta straight into the pan with the sauce. Toss everything together until the pasta is coated and creamy.

If the sauce feels too thick, add a splash of reserved pasta water to loosen it. If it’s slightly thin, keep tossing over the heat and the starch will thicken it naturally.

Stir through the grated parmesan and chopped parsley.

Taste and adjust seasoning if needed.

Serve immediately, finished with extra parmesan and black pepper.

Tips for best results

Don’t overcook the prawns. As soon as they’re pink and opaque, they’re done.

Toast the Cajun spice briefly before adding liquid. It wakes up the flavour.

Always reserve pasta water. It’s the easiest way to control sauce consistency.

If you like more heat, add a pinch of chilli flakes along with the Cajun spice.

If you prefer it extra creamy, add an extra spoon of cream cheese or a splash of double cream.

Use freshly grated parmesan for the best melt and flavour.

Storage and leftovers

This is best eaten fresh, as prawns can toughen when reheated.

If you do have leftovers, store in an airtight container in the fridge for up to 2 days.

Reheat gently in a pan with a splash of water to loosen the sauce. Avoid blasting it in the microwave for too long, or the prawns may overcook.

Freezing is not recommended due to the prawns and cream cheese sauce.

FAQs

Can I use frozen prawns?
Yes. Just make sure they’re fully thawed and patted dry before cooking.

Is this very spicy?
It has a mild to medium heat depending on your Cajun spice mix. Adjust the quantity to suit your taste.

Can I use chicken instead of prawns?
Absolutely. Slice chicken breast or thigh and cook it through before adding the stock.

What pasta works best?
Linguine, tagliatelle or fettuccine are great because the sauce clings well. Penne also works if that’s what you have.

Can I make it dairy-free?
You could try a dairy-free cream cheese alternative and skip the parmesan, but the flavour will change slightly.

What vegetables could I add?
Spinach, cherry tomatoes or sliced peppers would all work well and add colour.

Creamy, spicy, fast and full of flavour. This Cajun prawn pasta proves you don’t need a long ingredient list to make something that tastes big.

Twenty minutes, one pan, proper satisfaction. Weeknight dinner handled.
