Cajun chicken pasta is a great spicy recipe for pasta night! This pasta has a bit of a kick to it, mainly from the cayenne. It was a nice change from my regular pasta recipes. My recipe is from scratch – no jarred Alfredo. Has just the right amount of heat and creaminess.
Key Ingredients
- Chicken – Use boneless skinless chicken breasts for this dish. They shred up perfectly.
- Seasonings – Make a homemade cajun seasoning blend with cayenne pepper, red pepper flakes, oregano, onion powder, garlic powder, paprika, salt, and pepper. You can add more cayenne pepper for a bolder cajun flavor.
- Chicken broth – This is the base of the sauce and will help keep chicken breast moist during the cooking process.
- Heavy Cream – Makes the dish creamy and helps thicken it, don’t use half and half or milk.
- Parmesan Cheese – This adds flavor to the creamy alfredo sauce. You can use shredded parmesan cheese or grated parmesan cheese.
- Fettuccine Noodles – A classic noodle for cajun chicken pasta.
How to Make Cajun Chicken Alfredo
- Cook the chicken in seasoned broth until tender.
- Shred the chicken, then stir in cream, parmesan, and cooked pasta.
- Let it warm through until the sauce thickens and everything is well combined.
Tips & Variations
Shrimp – Add shrimp 15 minutes before the cooking time is done. Shred the chicken, add the cream and noodles and cook for the 20 additional minutes still. Make sure the shrimp is cooked through.
Andouille sausage – You can add one pound of sliced andouille sausage at the beginning of the cooking time.
Pasta Swap – You can use penne pasta instead of fettuccine noodles for a heartier noodle.
Add Veggies: To make this a complete meal, add steamed broccoli or frozen peas to the pasta just before serving.
Cream Swap: You can add a block of cream cheese to this dish instead of heavy cream. You can add it at the beginning of the cooking time, or microwave it for 30 seconds before adding the dish at the end of the cooking time.
Cajun Seasoning: You can use two teaspoons of cajun spice seasoning (such as Tony’s Chachere’s Creole Seasoning) instead of the different seasonings in this dish. Don’t add any more, for it can be on the salty side.
Why isn’t my Pasta Spicy?
Cayenne pepper loses its potency the longer it’s been on the shelf, or it may not be as spicy as other brands. You can add additional cayenne pepper after the dish is done cooking for more Cajun spice.

Ingredients
- 1 cup chicken broth
- 1/4 tsp. cayenne pepper
- 1/2 tsp. garlic powder
- 1/4 tsp. onion powder
- 1/2 tsp. dried leaf oregano
- 1/4 tsp. red pepper flakes
- 1 1/2 tsp. paprika
- 1 tsp. salt
- 1/4 tsp. pepper
- 2 lbs. boneless skinless chicken breasts
- 1 small white onion, diced
Add at the end:
- 1 lb. fettuccine noodles, cooked according to package directions
- 2 cups heavy cream
- 3/4 cup parmesan cheese, divided
- dried parsley or oregano for garnish
- paprika for garnish
Instructions
- Add the chicken broth to the slow cooker, add the cayenne, garlic powder, onion powder, oregano, red pepper flakes, paprika, salt and pepper. Stir.
- Add the chicken breasts and flip them around in the seasoned chicken broth to get the seasonings on the chicken.
- Sprinkle the onions over the chicken and broth.
- Cover and cook on low for 6 hours without opening the lid during the cooking time.
- After the cooking time is done, shred the chicken with two forks right in the slow cooker. Add the heavy cream.
- Add the cooked and drained pasta and a ½ cup of the Parmesan cheese. Stir.
- Sprinkle over the remaining parmesan cheese. I added a touch more paprika and also parsley flakes to the top of my pasta to make it look pretty. Cover and cook for 20 more minutes. Cooking for a bit longer helps the sauce thicken from the gluten in the pasta.
- Serve and enjoy!

I used chickpea pasta so I assume because itโs not gluten that was why the sauce didnโt thicken. Thatโs my own doing, but the recipe and taste was great! Thank you!

Do you think you could substitute cooked or roasted cauliflower instead of pasta? If so, could you estimate how much cauliflower to use?
Hi! I’m unsure about the amount. I would think about a half of a head.
