Ingredients You’ll Need
- 400g raw king prawns, peeled and deveined
- 1 tablespoon olive oil
- 2 tablespoons unsalted butter
- 3 cloves garlic, finely minced
- 1 medium onion, finely diced
- 1 red bell pepper, thinly sliced
- 200ml double cream
- 250ml chicken stock (or vegetable stock)
- 300g dried fettuccine or linguine
- 1 tablespoon tomato paste
- 1 teaspoon smoked paprika
- ½ teaspoon cayenne pepper (adjust to taste)
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- ½ teaspoon black pepper
- ½ teaspoon salt, plus more for pasta water
- Fresh parsley, chopped, for garnish
Tip: For the best texture, buy raw prawns that still have their tails on; they look beautiful on the plate and have a better bite than pre-cooked ones.
How to Make Creamy Cajun Shrimp Pasta
- Prepare the prawns: Pat the prawns completely dry with kitchen paper. In a small bowl, toss them with half of the smoked paprika, a pinch of cayenne, and a little salt. The prawns should look evenly dusted and smell faintly of spice. Set aside while you start the pasta.
- Cook the pasta: Bring a large pot of generously salted water to a rolling boil. Add your fettuccine and cook until al dente, usually about 1 minute less than the packet suggests. You’ll hear the pasta clatter against the pot as it goes in; that’s a good sound. Reserve a mugful of the starchy pasta water before draining.
- Sear the prawns: While the pasta cooks, heat the olive oil in a large frying pan over a medium-high heat until it shimmers. Add the prawns in a single layer—don’t crowd them, or they’ll steam. Listen for the immediate sizzle. Cook for 90 seconds per side, until they turn a vibrant pink with a golden-brown crust and feel firm to the touch. Transfer them to a clean plate.
- Build the base: Reduce the heat to medium. Add the butter to the same pan; watch it melt and foam gently. Tip in the diced onion and sliced red pepper. Stir, and you’ll smell the sweetness begin to release. Cook for 4-5 minutes until the onion is translucent and the pepper has softened, the edges just beginning to catch colour.
- Bloom the spices: Add the minced garlic, remaining smoked paprika, cayenne, oregano, thyme, and black pepper. Stir constantly for about 45 seconds. The kitchen will fill with a warm, smoky perfume, and the garlic should be fragrant but not browned. Add the tomato paste and stir for another minute, watching it darken slightly as it cooks.
- Create the sauce: Pour in the chicken stock, using a wooden spoon to scrape up all the browned bits from the bottom of the pan—that’s pure flavour. Let it simmer for 2 minutes until it reduces slightly and looks glossy. Stir in the double cream, and watch the colour shift from a deep brick red to a beautiful, creamy coral. Let it bubble gently for 3-4 minutes until it thickens enough to coat the back of your spoon.
- Bring it together: Add the drained pasta and the seared prawns to the pan. Use tongs to toss everything thoroughly, coating every strand of pasta in that luscious sauce. If it seems a little thick, add a splash of the reserved pasta water—it will loosen the sauce and help it cling. Taste and adjust salt and cayenne. The pasta should look glossy and the prawns should be nestled throughout.
- Rest and serve: Let the pan sit off the heat for 2-3 minutes. This brief rest allows the flavours to meld and the sauce to settle into the pasta. Serve immediately in warmed bowls, garnished with a generous sprinkle of fresh parsley. The steam rising from the bowl will carry that final, aromatic note.
Tips From My Kitchen
- Make your own Cajun blend: Pre-mixed Cajun seasoning can vary wildly in salt content. By mixing your own smoked paprika, cayenne, oregano, and thyme, you control the heat and the sodium. I make a small jar of it to keep on hand—it’s a game-changer for this dish and for a simple Grilled Chicken Pasta Salad Easy.
- Dry prawns are happy prawns: Moisture is the enemy of a good sear. If your prawns are even slightly damp, they will steam in the pan rather than developing that beautiful golden crust. Pat them down with kitchen paper just before they hit the oil.
- Don’t skip the pasta water: That starchy, salty water is liquid gold. It helps to emulsify the cream sauce, giving it a silky, restaurant-quality finish that clings to every piece of pasta. Always save a cup before you drain.
- Low and slow for the sauce: Once you add the cream, keep the heat at a gentle simmer. A vigorous boil can cause the cream to split and become grainy. You want small, lazy bubbles across the surface, not a frantic rolling boil.
- Rest before serving: This is the step many people skip, but it’s crucial. Those two minutes off the heat allow the sauce to relax and coat the pasta evenly. It also brings the temperature down just enough so you don’t burn your mouth on the first, eager forkful.
Equipment You’ll Need
- Large pot for boiling pasta
- Colander for draining
- Large frying pan or skillet (preferably with a lid)
- Tongs or a pasta fork for tossing
- Wooden spoon or silicone spatula
- Measuring spoons and cups
- Sharp knife and chopping board
Common Mistakes to Avoid
- Overcrowding the pan: If you pile too many prawns into the pan at once, they release too much moisture and end up boiling in their own juices. You lose that prized golden crust. Sear them in a single layer, and if you have a lot, cook them in two batches. It adds only two extra minutes, and the texture is incomparable.
- Wrong temperature: Cooking the garlic and spices over too high a heat will burn them, turning them bitter and acrid. The butter should foam gently, not sizzle aggressively. Keep a medium heat for the aromatics, and only crank it up for the initial sear on the prawns.
- Skipping the rest time: It’s tempting to serve straight from the stove, but the sauce hasn’t had a chance to meld with the pasta. Those final 2-3 minutes off the heat are when the magic happens—the flavours marry, the sauce thickens slightly, and the dish becomes truly cohesive rather than just pasta with a separate sauce.
Delicious Variations to Try
- Spicy Version: For those who like a real kick, add a finely chopped red chilli (seeds and all) along with the garlic. You can also increase the cayenne pepper to a full teaspoon, or finish the dish with a drizzle of hot chilli oil just before serving.
- Vegetarian/Vegan Option: Swap the prawns for 250g of firm tofu, pressed and cubed, or a generous handful of king oyster mushrooms sliced into thick rounds. Use a good vegan butter and replace the double cream with a full-fat coconut cream or a thick cashew cream. The Cajun spices work beautifully with both.
- Different Protein: This sauce is a fantastic canvas. Try it with diced chicken breast (seared first in the same pan), or with chunks of firm white fish like cod or haddock. For a different flavour entirely, use sliced andouille-style chicken sausage—the smoky notes are a natural fit.
What to Serve With Creamy Cajun Shrimp Pasta
- A simple green salad with a sharp lemon vinaigrette to cut through the richness.
- Garlic bread or crusty sourdough to mop up every last bit of the sauce from the bowl.
- Steamed green beans or tenderstem broccoli, simply dressed with a little butter and salt.

Frequently Asked Questions
Can I use frozen prawns?
Absolutely, and they often work very well. The key is to thaw them completely in the fridge overnight, then pat them extremely dry with kitchen paper before cooking. Any residual water will prevent them from searing properly, so be thorough with the drying step.
Can I make this dish dairy-free?
Yes, you can. Substitute the butter with a good-quality vegan block butter, and use a full-fat coconut cream or a thick oat-based cream alternative in place of the double cream. The sauce will have a slightly different texture but will still be wonderfully rich and flavourful.
How do I stop the cream sauce from splitting?
The most common cause is heat that is too high. Once you add the cream, keep the pan over a gentle heat—a low simmer with small bubbles, not a rolling boil. Also, ensure your cream is at room temperature before adding it to the pan to prevent a thermal shock.
Can I add vegetables to this pasta?
Certainly. Sliced courgette, asparagus tips, or halved cherry tomatoes are all lovely additions. Add firmer vegetables like courgette along with the onion and pepper, and add more delicate items like cherry tomatoes or spinach right at the end, just before you toss in the pasta.
How should I store and reheat leftovers?
Store any leftovers in an airtight container in the fridge for up to two days. To reheat, place the pasta in a frying pan with a splash of milk or stock and warm it gently over a low heat, stirring often. Avoid the microwave if you can, as it tends to make the prawns rubbery and the sauce grainy.
