Chicken and pasta are mainstays around here. In fact, either chicken or pasta show up on our dinner table multiple nights each week. One of our favorites is creamy Cajun chicken pasta. This is a copycat dish from Chili’s restaurant, and is arguably one of their best and most popular dishes.


The first step is to grill your Cajun spiced chicken breasts. There are a few ways you can prepare the chicken for your this dish. It can either be grilled on an outdoor grill, indoors on a grill pan, or sauteed in a skillet. Chicken thighs can be substituted in place of breasts, if desired.

While the chicken is cooking, I boil my pasta and make the creamy sauce. The chicken gets arranged over the top of the pasta, and the finishing touch is a sprinkling of fresh diced tomatoes, green onions and shredded parmesan cheese.

Tips for Cajun chicken pasta

  • For this dish, any short pasta will work if you don’t have penne on hand.
  • No green onions? Try chopped parsley or basil instead.
  • This dish tastes best if you make it with freshly grated parmesan cheese.
  • You can also try making this recipe with Cajun shrimp instead of chicken.

Any pasta that is smaller or “shorter” in size such as penne, is considered a short pasta. Pasta such as spaghetti wouldn’t work because it’s not a short pasta. Other short pastas are elbow macaroni, cavatappi, rigatoni, etc. I love using penne in this dish because the ridges on the pasta really help that creamy sauce cling to each noodle.


Homemade Cajun seasoning is a delicious and easy spice to make on your own. It’s made with a blend of garlic powder, herbs and spices. I definitely recommend making your own if you can, as I think it has a much better flavor than the store bought kind.


You can use store bought Cajun seasoning for the recipe, or make your own. To make Cajun seasoning, combine 2 1/2 tablespoons paprika, 1 1/2 tablespoons salt, 1 1/2 tablespoons garlic powder, 1 tablespoon black pepper, 1 tablespoon onion powder, 1 tablespoon dried oregano,  2 teaspoons cayenne pepper and 1 1/2 teaspoons dried thyme. Mix everything together and store in an airtight container until you’re ready to use it.

I’ve always loved taking the family out for a nice dinner from time to time. However, I also love when I can capture one of our favorite dishes without having to go out and get it from a restaurant. Cajun chicken pasta has definitely made it onto our favorites list!

    The perfect mix of spicy and creamy, with tender pieces of chicken and the right amount of heat. It’s definitely a go-to recipe for a flavorful and satisfying meal.

    I made this a few nights ago and it was delicious! The only change I made was adding one garlic to the Alfredo sauce. The consistency of the Alfredo is perfect! Not too heavy and coated the pasta just right. It is so good I am planning to make it again today for lunch, using salmon as a protein this time. Thank you for posting this recipe!

  3. This looks absolutely amazing! I need to give this a try real soon. I’m saving this so I can make it later. Can’t wait to give it a try!

    My family loves pasta so much and this cajun chicken pasta recipe looks really delicious and looks so easy to make. I will try to make this for my family and I am sure they will love it.

  5. This looks absolutely amazing! Definitely going to have to give this a try. My husband loves Cajun chicken!

  6. This looks amazingly delicious! While I personally don’t eat chicken or any kind of meat for that matter, I know that my family would enjoy this recipe. Especially, my oldest son. He LOVES chicken.

      But all you have to do is use a substitute meat & get all those other delicious flavours, that’s what I do. And did, in this case. I’m not sure if the UK ‘Cajun’ powders are the same but I thoroughly enjoyed this,wonderful with salads & jacket spuds. I wish people would comment more on how they enjoyed a recipe or what they did to tweak it to make it different, rather than just say they intend to do it, I have to trawl through that & it isn’t at all interesting.

  7. 5 stars
    I couldn’t imagine how the cajun flavors would work in a pasta dish but I do have to say that it looks amazing. I will definitely show this to my family!
