Ingredients

• 16 oz. fettuccine, cooked al dente
• 2 lbs boneless, skinless chicken breasts
• 2 tablespoons Cajun seasoning, divided
• ½ teaspoon smoked paprika
• Pepper to taste
• 2 tablespoons butter, divided
• 1 tablespoon olive oil
• 3​-4 cloves garlic, minced
• 1 tablespoon tomato paste
• 1 cup chicken broth
• 2 cups heavy cream
• 4 tablespoons parsley, finely chopped
• ½ cup Parmesan cheese, freshly grated
• 1 ½ tablespoons lemon juice

Step​-by​-Step: How to Make Creamy Cajun Chicken Pasta

1. Boil a generous pot of salted water and cook the fettuccine until it reaches al dente, following the directions on the package.
2. Meanwhile, pound the chicken breasts to an even 1​-inch thickness. Season both sides of the chicken with 1 tablespoon of Cajun seasoning, the smoked paprika, and pepper to taste.
3. In a large skillet or Dutch oven over medium​-high heat, melt 1 tablespoon of butter and add the olive oil. Sear the chicken on each side until golden brown and cooked through (internal temperature ~165 °F), about 4​-5 minutes per side. Transfer the chicken to a cutting board, slice into thick pieces or bite​-sized chunks, and set aside along with any juices.
4. Reduce heat to medium. In the same skillet, melt the remaining 1 tablespoon of butter and sauté the minced garlic for about 30 seconds until fragrant. Add the tomato paste and stir to combine. Then pour in the chicken broth and heavy cream, scraping any browned bits from the bottom of the pan. If you saved the chicken juices, you can add them now for extra flavour.
5. Bring the sauce to a gentle boil, then add the chopped parsley and slowly stir in the grated Parmesan cheese until the sauce becomes smooth and slightly thickened.
6. Add the remaining 1 tablespoon of Cajun seasoning, the lemon juice, and pepper to taste. Taste the sauce and adjust seasonings as needed. Let it simmer for another ~5 minutes until it reaches your desired thickness.
7. Add the cooked fettuccine to the skillet and toss to coat thoroughly in the creamy sauce. Then either mix in the sliced chicken or place the chicken pieces on top of the pasta as you serve.
8. Dish up immediately, and optionally sprinkle extra parsley and Parmesan over the top for garnish. Serve hot. Enjoy!

Helpful Tips

• Be careful not to overcook the chicken—pounding it to an even thickness ensures it cooks evenly and stays tender.
• When sautéing garlic, keep the heat moderate and watch carefully—garlic burns quickly and can turn bitter.
• When adding the cream and cheese, stir continuously so the sauce remains smooth and doesn’t separate.
• The sauce will thicken as it cools a bit; if it gets too thick, stir in a splash of broth or cream when reheating.
• Use freshly grated Parmesan rather than pre​-grated for better melting and flavour.
• If you’re sensitive to spice, start with a lesser amount of the Cajun seasoning and adjust upward—many Cajun blends vary significantly in heat and salt content.
• Cook the pasta until just al dente so it doesn’t become mushy when tossed in the sauce.

Substitutions And Variations

• Protein swap: Instead of chicken breasts, you can use boneless chicken thighs, sliced sausage (such as andouille), or even shrimp or scallops for a seafood twist.
• Vegetables added: Bell peppers, onions, mushrooms, or frozen peas add colour, texture, and nutrition. Some one​-pan versions include the “holy trinity” of bell pepper, celery and onion for a deeper Cajun base.
• Lighter cream: If you’d like a lighter version, substitute half the heavy cream with half​-and​-half or milk—but note the sauce may be thinner.
• Spice level: If your Cajun seasoning is especially salty or hot, reduce the amount and add more gradually to taste.
• Dairy free or lower fat: Omit or reduce the cheese, and use a lighter milk or a non​-dairy cream alternative—but the sauce texture will differ.
• Pasta shape: While the recipe uses fettuccine, you can use linguine, penne, rigatoni, or even a short pasta shape. Just mind cooking times.

Storage Instructions

Place any leftovers in a sealed container and refrigerate for up to 3 to 4 days. When reheating, add a splash of chicken broth or milk to loosen the sauce, then gently warm through on the stove or in the microwave. Note: the pasta may absorb more sauce on storage, so a little extra liquid helps restore the creamy texture.
Freezing is possible (the sauce may thicken and texture may change slightly). Thaw overnight in the fridge and reheat gently, adding liquid if needed.

Serving Suggestions

• Serve this dish with a simple green salad dressed with vinaigrette to balance the richness of the cream sauce.
• Garlic bread or focaccia make an excellent accompaniment to soak up any remaining sauce.
• Add a squeeze of fresh lemon or a sprinkle of fresh parsley right before serving to brighten the flavours.
• For a side vegetable, roasted broccoli or steamed asparagus pair nicely and add colour to the plate.
• If you like spice, serve with hot pepper flakes or sliced jalapeños on the side so diners can adjust to taste.

Frequently Asked Questions About Creamy Cajun Chicken Pasta

Q: Can I make this ahead of time?
Yes — you can cook the chicken and pasta ahead, but I recommend waiting to toss them together with the sauce until just before serving. The pasta tends to absorb the sauce as it sits, which can change texture. When reheating, add extra broth or cream to refresh the sauce.

Q: How can I reduce the spice if I’m not good with heat?
If you’re sensitive to spice, use a milder or smaller amount of the Cajun seasoning. Since blends vary widely in heat and salt content, start with half the amount your recipe calls for and taste before adding more.

Q: Can I use a different pasta type or gluten​-free option?
Absolutely — any hearty pasta shape works, from penne to rigatoni or even gluten​-free pasta. Just make sure the texture is sturdy enough to hold the creamy sauce, and adjust cooking time based on the pasta package instructions.

Q: My sauce separated / curdled a little when reheating. What happened?
Cream​-based sauces can sometimes separate when reheated too quickly or at high heat. To avoid this, reheat gently over medium​-low, stir continuously, and add a splash of milk or chicken broth to help bring it back together. Freshly grated cheese melts more smoothly too.

Q: Can I lighten this dish or make it dairy​-free?
Yes — you can reduce the heavy cream, use half​-and​-half or even milk, and omit or reduce the Parmesan cheese. For dairy​-free, you can use a non​-dairy cream substitute, though texture and flavour may differ. Keep in mind the sauce will be thinner and less rich.
