Ingredients for the Perfect Creamy Cajun Shrimp Pasta
For this recipe, we’ve chosen a small selection of simple but impactful ingredients to build delicious layers of flavour. Opting for fresh, good-quality produce will elevate the final dish. Here is everything you will need to have ready:

- Pasta: We find that a long pasta such as linguine, fettuccine, or spaghetti works best, as it captures the creamy sauce so well. You’ll need about 350g (12 oz) for four generous portions.
- Raw King Prawns: Around 450g (1 lb) of large raw prawns, peeled and deveined, are required. For a touch of restaurant-style presentation, you can leave the tails on.
- Olive Oil and Butter: Using one tablespoon of each provides a perfect partnership; the oil has a high smoke point, while the butter imparts a rich flavour for searing the prawns.
- Garlic: Four cloves, minced very finely. In our opinion, you can never have too much garlic, but do adjust this amount to suit your own preference.
- Double Cream: This is the secret to our incredibly rich and creamy sauce. You will need 300ml (1 ¼ cups).
- Chicken or Vegetable Stock: A measure of 120ml (½ cup) of stock helps to loosen the sauce to an ideal consistency without watering down the flavour.
- Cajun Seasoning: The hero ingredient! You’ll want 1 to 2 tablespoons of your preferred Cajun seasoning blend. The precise amount will vary based on saltiness and spice preference. To delve deeper into this blend’s origins, you can learn about Cajun cuisine and its fascinating history.
- Parmesan Cheese: Always use freshly grated! Prepare about 50g (½ cup), with a little extra for serving. It lends a wonderful salty, nutty character to the sauce.
- Fresh Parsley: A small, chopped handful for the garnish. This adds a lovely freshness and a pop of colour that cuts through the sauce’s richness.
- Lemon Juice: A little squeeze from half a lemon right at the end really makes all the flavours sing.
- Salt and Black Pepper: To season every component perfectly.
How to Make Creamy Cajun Shrimp Pasta: A Step-by-Step Guide
Creating this dish is a remarkably straightforward affair. We have organised the process into four easy-to-follow stages to guarantee flawless results every single time. Simply follow our lead, and you’ll be serving up a culinary masterpiece before you know it.
Begin by filling a large pot with water, adding a generous amount of salt, and bringing it to a vigorous boil. Add your chosen pasta and cook it following the packet’s directions until it is al dente—cooked through but with a slight firmness. Before you drain it, carefully scoop out and set aside about 240ml (1 cup) of the starchy cooking water. This liquid serves as an excellent natural thickener for your sauce. Drain the pasta and set it aside. Then, sauté the prawns.
While your pasta is cooking, take your peeled and deveined prawns and pat them dry with a piece of kitchen roll. This step is essential for achieving a nice sear instead of merely steaming the food. Season the prawns liberally with about half of your Cajun seasoning, plus some salt and pepper. Heat a large skillet or frying pan over medium-high heat, then add the extra virgin olive oil and butter. When the butter has softened and begun to foam, arrange the prawns in a single layer. Cook for 1-2 minutes on each side until they are pink and translucent. Be careful not to overcook them, as this may cause them to become tough. Remove the baked prawns from the pan and place them on a plate. Next, prepare the Velvety Cajun Cream Sauce.
Using the same skillet, reduce the heat to medium. Add the minced garlic and let it cook for around 30 seconds until it becomes fragrant, making sure to scrape up any tasty browned bits from the pan’s base. Pour in the broth to degrease the pan, then add the heavy cream. Whisk and bring to a gentle boil. Then add the remaining Cajun seasoning and grated Parmesan. Keep whisking until the cheese completely melts and the sauce becomes smooth and slightly thickened. This is where you’ll create the perfect, tangy cream sauce. Taste and season with salt, pepper, or Cajun seasoning to your liking. Bring It All Together. Place the cooked prawns back into the skillet with their juices.. Tip the drained pasta directly into the pan and toss everything together until the pasta is evenly coated in the wonderful sauce. If your sauce is too thick, add some reserved pasta water to achieve your desired consistency. To finish, stir through the chopped fresh parsley and add a generous squeeze of lemon juice to brighten the entire dish. Serve straight away, garnishing with an extra sprinkle of Parmesan and a little more fresh parsley.

Our Top Tips for the Best Pasta Dish
To help you transform your Creamy Cajun Shrimp Pasta from merely good to truly spectacular, we suggest keeping these handy tips in mind:
- Don’t Overcook the Prawns: This is our number one rule. Prawns cook in a flash, and overcooked ones become disappointingly chewy. Sauté them until they turn pink and curl, then remove from heat immediately.They will cook a little more when returned to the hot sauce.
- Use Freshly Grated Parmesan: Packaged pre-grated cheese often includes additives that can stop it from melting properly into a sauce. Grating cheese from a block of Parmesan yields a creamier and more flavorful product.
- Reserve Your Pasta Water: We’ve said it before, but it’s a game-changer! This starchy water serves as an excellent emulsifier, allowing the sauce to adhere to the pasta beautifully and giving you control over its final thickness.
- Taste and Adjust: Not all Cajun seasoning blends are created equal; they can vary widely in salt and heat levels. Always start with a conservative amount, taste your sauce, and then add more until the flavour is perfectly balanced for you.
Customise Your Creamy Cajun Shrimp Pasta
One of the finest qualities of this recipe is its wonderful versatility. It’s incredibly easy to modify to match your personal taste or to make use of whatever ingredients you have in the kitchen. Here are some of our favourite ways to adapt it:
-
- Add Some Veggies: Sliced bell peppers of any colour, onions, mushrooms, or even sun-dried tomatoes are all fantastic additions. Sauté them after the garlic but before you pour in the cream. You can also add a few large handfuls of fresh spinach at the end.
– **Try a Different Protein:** If prawns aren’t your thing, this sauce is equally delicious with sliced chicken breast, smoky andouille sausage, or even delicate scallops.
- Make it Extra Spicy: For those who enjoy a serious kick of heat, add a pinch of cayenne pepper or a few dashes of your go-to hot sauce when you add the Cajun seasoning.
- Go Dairy-Free: To create a dairy-free alternative, you can substitute double cream with full-fat coconut milk or a plant-based cream option. The flavour profile will change slightly but will remain incredibly tasty.
Frequently Asked Questions
Can I prepare this creamy Cajun shrimp pasta ahead of time?
This dish is truly at its most delicious when served immediately, as cream-based sauces tend to thicken and prawns can become chewy when reheated. If you do need to prepare in advance, you can make the sauce and store it in an airtight container in the fridge for up to two days. When you’re ready to serve, gently warm the sauce on the hob, cook your pasta and prawns fresh, and then combine everything at the last minute.
What is the best way to store and reheat leftovers?
Store any leftovers in an airtight container in the refrigerator for up to two days. To reheat, we recommend placing the pasta in a pan over a low heat with a little splash of milk or stock to help loosen the sauce. Warm it through gently, taking care not to let it get too hot, which can toughen the prawns.
What’s the best pasta shape to use?
We are particularly fond of long, flat pasta shapes like fettuccine or linguine, as they offer plenty of surface area for that creamy sauce to adhere to. With that said, short pasta with plenty of texture, such as penne, rigatoni, or fusilli, are also superb choices because they trap the sauce in all their ridges and curves.
Can I use frozen prawns?
Of course! Using frozen raw prawns is an excellent and convenient choice. It’s essential to make sure that they are completely thawed before cooking. You can achieve this by leaving them in the refrigerator overnight or, if you’re short on time, placing them in a colander and rinsing them with cold water for a few minutes.
What should I serve for dessert after this rich pasta?
Following such a hearty and flavour-packed main course, a simple, comforting dessert often makes the perfect finale. For a timeless sweet treat, why not give our easy Banana Bread a go? Or, if you’re in the mood for something a bit more indulgent, our Banana Bread Brownies are a guaranteed hit with everyone.
