Why You’ll Love This One-Pot Creamy Cajun Chicken Pasta
- One pot, minimal mess: You only need a large, deep skillet or pot. No separate pans for boiling pasta or cooking sauce means less scrubbing after dinner.
- Fast enough for a busy weeknight: From chopping the first onion to serving the final plate takes just over half an hour, making it faster than a takeaway delivery.
- Deep, complex flavour without fuss: The Cajun seasoning does all the heavy lifting, creating a smoky, slightly spicy base that tastes like it has been simmering for hours.
- Uses everyday ingredients: You likely have most of these in your fridge and cupboard already. It’s a fantastic way to use up chicken breasts and a bit of double cream.
- Perfect for making ahead: The leftovers reheat beautifully, and I often double the batch so we have lunch sorted for the next day.
Ingredients You’ll Need
- 2 tablespoons olive oil
- 500g boneless, skinless chicken breasts, cut into bite-sized pieces
- 1 large onion, finely chopped
- 3 cloves garlic, minced
- 1 red bell pepper, diced
- 1 yellow bell pepper, diced
- 2 tablespoons Cajun seasoning
- 1 teaspoon smoked paprika
- 400ml chicken stock
- 300ml double cream
- 250g dried penne pasta (or any short pasta)
- 100g grated Parmesan cheese
- Salt and freshly ground black pepper, to taste
- Fresh parsley, chopped, for garnish
Tip: For the best flavour, use a good-quality Cajun seasoning blend. If you are sensitive to salt, check the label and adjust the salt you add later accordingly. Friends always ask me for this recipe after trying it at dinner parties, and the secret is always the seasoning.
How to Make One-Pot Creamy Cajun Chicken Pasta
- Brown the chicken: Heat the olive oil in a large, deep pot or Dutch oven over a medium-high heat. Add the chicken pieces in a single layer — you should hear a satisfying sizzle. Cook for 3-4 minutes until the underside is golden brown and you can see a crisp, caramelised edge. Flip and cook for another 2 minutes. The chicken should smell nutty and look golden. Remove with a slotted spoon and set aside.
- Sweat the aromatics: Reduce the heat to medium. Add the chopped onion to the pot. Stir and scrape up any browned bits from the bottom. Cook for 3 minutes until the onion turns translucent and softens. You will notice the raw onion smell mellowing into a sweet fragrance. Add the minced garlic and cook for just 30 seconds until it becomes fragrant — do not let it brown.
- Build the base: Tip in the diced red and yellow bell peppers. Cook for 4-5 minutes, stirring occasionally, until they begin to soften and release their moisture. The peppers will turn vibrant and the kitchen will smell wonderfully sweet.
- Add the seasoning: Sprinkle over the Cajun seasoning and smoked paprika. Stir continuously for 1 minute. This step is crucial — it toasts the spices, releasing their oils and deepening their flavour. The aroma will become smoky and intense.
- Pour in the liquids: Pour in the chicken stock and the double cream. Stir well to combine, scraping the bottom of the pot to lift any flavourful bits. Bring the mixture to a gentle simmer. You will see small bubbles breaking the surface, and the sauce will start to thicken slightly. The colour should be a beautiful, warm orange.
- Cook the pasta: Add the dried penne pasta directly into the pot. Stir to ensure every piece is submerged in the liquid. Bring to a boil, then reduce the heat to a low simmer. Cover the pot with a lid and cook for 12-15 minutes, stirring halfway through. The pasta will absorb the sauce and swell. The sauce will become thicker and creamier. Check the pasta is al dente by tasting a piece — it should be tender but still have a slight bite.
- Finish the dish: Return the browned chicken to the pot, along with any juices that have collected on the plate. Stir in the grated Parmesan cheese until it melts into the sauce. The cheese will add a salty, nutty richness and the sauce will become silky and glossy. Season with salt and black pepper to taste. Remove from the heat.
- Rest and serve: Let the pasta sit for 2-3 minutes. This allows the sauce to thicken further and cling beautifully to every piece of pasta. Garnish generously with fresh chopped parsley. The final dish should look luscious, with a creamy, speckled sauce coating the chicken and pasta.
Tips From My Kitchen
- Don’t skip browning the chicken: This step creates a deep, savoury flavour base through the Maillard reaction. The browned bits left in the pot are pure gold for the sauce. My husband, who’s usually picky, asked for seconds the first time I made this, and I credit that initial sear.
- Toast your spices: Adding the Cajun seasoning to the hot vegetables for a minute before adding the liquid unlocks their volatile oils. It transforms the spice blend from tasting raw and dusty to warm, smoky, and complex.
- Use a heavy-bottomed pot: A heavy pot distributes heat evenly, preventing the dairy from scorching on the bottom. A cast-iron Dutch oven or a good-quality stainless steel pot works brilliantly.
- Stir halfway through pasta cooking: Dried pasta has a tendency to stick to the bottom as it absorbs liquid. A quick stir after about 6-7 minutes ensures even cooking and prevents any sticky clumps.
- Reserve a splash of stock: If the sauce looks too thick after the pasta has finished cooking, stir in a splash of warm chicken stock. This loosens it without diluting the flavour. If it is too thin, let it simmer uncovered for a couple of minutes.
- Make it ahead: This pasta is fantastic as a make-ahead meal. Prepare it completely, then cool and refrigerate. To reheat, add a splash of milk or stock and warm gently on the hob, stirring often. The flavours actually deepen overnight.
Delicious Variations to Try
- Spicy Version: To ramp up the heat, add a finely chopped red chilli or a teaspoon of cayenne pepper along with the Cajun seasoning. You can also finish the dish with a drizzle of chilli oil before serving for an extra kick.
- Vegetarian/Vegan Option: Swap the chicken for a large can of drained chickpeas or a block of firm tofu, cubed and pan-fried until golden. Use a good-quality vegetable stock instead of chicken stock, and replace the double cream with full-fat coconut milk or a dairy-free cream alternative. Nutritional yeast can stand in for the Parmesan.
- Different Protein: Sliced beef steak or turkey breast work wonderfully in this dish. Simply adjust the cooking time to ensure the meat is cooked through. For a seafood twist, add raw peeled prawns during the last 3 minutes of cooking the pasta — they will turn pink and perfectly cooked.
What to Serve With One-Pot Creamy Cajun Chicken Pasta
- A simple green salad with a sharp vinaigrette to cut through the creaminess. Try our 10 Minute Avocado And Red Onion Salad for a fresh, zesty side.
- Garlic bread or crusty baguette for mopping up every last bit of the creamy sauce from the bowl.
- Steamed green beans or broccoli, simply seasoned with salt and a squeeze of lemon, for a pop of colour and extra vegetables.
- A light, tangy side like our Cold Tortellini Salad With Pesto if you are serving a crowd and want a variety of textures.

Frequently Asked Questions
Can I use milk instead of double cream?
You can, but the sauce will be significantly thinner and less rich. Double cream provides the luxurious, velvety texture that makes this dish so satisfying. If you want a lighter option, use half double cream and half whole milk, or stir in a tablespoon of cream cheese at the end to add body back into the sauce.
What type of pasta works best for this recipe?
Short, sturdy pasta shapes work best because they hold up well to the creamy sauce and the one-pot cooking method. Penne, fusilli, rigatoni, or farfalle are all excellent choices. Avoid long, delicate pasta like spaghetti, as it tends to clump together when cooked in a smaller amount of liquid.
How do I store and reheat leftovers?
Store any leftovers in an airtight container in the fridge for up to three days. To reheat, place the pasta in a pot over a low heat with a splash of milk or chicken stock. Stir gently until the sauce loosens and the pasta is hot throughout. Avoid using the microwave if possible, as it can make the sauce separate and become grainy.
Can I freeze this creamy Cajun chicken pasta?
Yes, you can freeze it, but the texture of the cream sauce may change slightly upon thawing. For the best results, allow the pasta to cool completely, then transfer it to a freezer-safe container. Freeze for up to two months. Thaw overnight in the fridge and reheat gently on the hob, adding a little extra cream or stock to restore the silky consistency.
Is this dish very spicy?
The level of heat depends entirely on your Cajun seasoning blend. Most standard blends are moderately spiced, offering a warm, smoky kick rather than intense heat. If you are cooking for children or those sensitive to spice, use a mild Cajun seasoning or reduce the amount by half. You can always add more heat at the table.
