This Cajun Chicken Alfredo combines tender chicken chunks coated in bold Cajun spices with a creamy parmesan sauce and perfectly cooked fettuccine for a restaurant-quality meal you can make at home.
I first made this Cajun Chicken Alfredo for my family game night and it became an instant hit. My kids who normally shy away from spicy foods kept asking for seconds, and now it's our go-to special dinner when guests come over.
Ingredients
- Fettuccine pasta: Forms the hearty base of this dish and holds up perfectly to the rich sauce
- Chicken breasts: Provide lean protein and become incredibly flavorful when coated in Cajun seasoning
- Cajun seasoning: Delivers that authentic Louisiana flavor profile with its blend of paprika, garlic, and herbs
- Butter: Adds richness and helps create a silky sauce texture
- Garlic puree: Intensifies the flavor foundation and pairs beautifully with the cream
- Heavy cream: Creates that luxurious restaurant-quality sauce you crave
- Parmesan cheese: Thickens the sauce and adds a savory depth that balances the spices
- Fresh chives: Bring a mild onion flavor and vibrant color contrast to finish the dish
Step-by-Step Instructions
- Prepare the Pasta:
- Cook the fettuccine according to package directions until al dente. Be sure to salt your pasta water generously for proper flavor. Drain but do not rinse as the starch helps the sauce adhere better.
- Season the Chicken:
- Cut chicken breasts into uniform 1-inch cubes to ensure even cooking. Place chicken chunks in a mixing bowl and add Cajun seasoning, making sure every piece is thoroughly coated. The seasoning will create a flavorful crust on the chicken as it cooks.
- Cook the Chicken:
- Add the seasoned chicken to a large sauté pan over medium-high heat. Allow the chicken to cook for 8 minutes, stirring occasionally but not constantly to allow proper browning on all sides. The chicken should develop a nice sear while remaining juicy inside.
- Create the Sauce Base:
- Add butter and garlic puree to the pan with the cooked chicken. Stir until the butter is completely melted and the garlic becomes fragrant, about 30 seconds. This builds the aromatic foundation for your creamy sauce.
- Develop the Cream Sauce:
- Pour in the heavy cream along with salt and pepper. Stir thoroughly to incorporate all ingredients and bring to a gentle boil. The cream will begin to take on the beautiful color of the Cajun spices. Cover with a lid and reduce heat to medium-low, allowing the sauce to simmer for 8 minutes to thicken and develop flavor.
- Combine with Pasta:
- Add the cooked fettuccine to the pan with the sauce and toss until every strand is coated. Allow the pasta to cook in the sauce for 4 additional minutes, which helps it absorb some of the flavors and further thickens the sauce.
- Finish the Dish:
- Sprinkle the shredded Parmesan into the pan and stir gently until completely melted and incorporated into the sauce. Finally, add the fresh chopped chives and give everything a final toss before serving. The cheese will help bind the sauce to the pasta creating a cohesive, luxurious dish.

My absolute favorite part of this recipe is watching the sauce transform as it simmers. The way the cream takes on the beautiful orange-red hue from the Cajun spices reminds me of cooking with my grandmother who taught me that patience builds flavor. Every time I make this dish, I think of her saying "good food takes time, even when it's quick."
Make It Ahead
This Cajun Chicken Alfredo reheats beautifully making it perfect for meal planning. Store in airtight containers in the refrigerator for up to 3 days. When reheating, add a splash of milk or cream to revive the sauce, and warm gently over medium-low heat. The flavors actually continue to develop overnight, making next-day leftovers something to look forward to rather than simply tolerate.
Spice Level Adjustments
Cajun cuisine is known for its bold flavors but you can easily tailor this dish to suit your family's preferences. For a milder version cut the Cajun seasoning to 2 tablespoons or substitute with a blend of paprika, garlic powder, and dried herbs. For heat lovers add a pinch of cayenne pepper or red pepper flakes when making the sauce. Remember that the dairy in the cream sauce helps temper the spice naturally.
Perfect Pairings
Complete your meal with a simple side salad dressed with lemon vinaigrette to cut through the richness of the cream sauce. Garlic bread makes an excellent accompaniment for soaking up any extra sauce. For beverages a crisp white wine like Pinot Grigio or Sauvignon Blanc complements the creamy texture, while a light beer also works wonderfully for casual dining.
Texture Secrets
The key to a perfect Cajun Chicken Alfredo lies in the sauce consistency. If your sauce seems too thin after adding the pasta, continue cooking uncovered for a few extra minutes. If too thick add a splash of pasta cooking water which contains starch that helps maintain the silky texture. Always serve immediately after adding the Parmesan for the optimal creamy consistency that coats each strand of pasta perfectly.
