❤️Why we love this recipe
- A delicious classic. A classic pasta dish that's rich, creamy, and has so much flavor. With just the right amount of kick, it's major comfort food!
- Protein packed. The juicy and tender chicken breast adds a protein-rich element to the dish, making it filling and satisfying.
- Simple ingredients. This recipe is made with 9 simple ingredients that you probably already have on hand in your pantry and kitchen. Anything you need can be found at your local grocery store.
- Quick and easy recipe. Getting a complete meal on the table in under an hour is not an easy task, but this recipe is straight forward and quick to make.
🍝Ingredients
Here are the ingredients we used for this recipe. You can find more information for substitutions below.
- Boneless skinless chicken breast. Chicken thighs can also be used.
- Cajun seasoning. We like making our own homemade Cajun seasoning blend, but you can use your favorite Cajun seasoning. If using a store- bought version, you probably don't need any extra salt, as these versions usually have a lot of added sodium.
- Parmesan cheese. Freshly grated. This is important. Pre-shredded bags of cheese don't always melt properly, because they have additives in them, so you'll want to grate it yourself, or else you will end up with a lumpy sauce!
- Pasta. We'd recommend using fettuccine or linguine pasta.
- Pasta water. Liquid gold! Starchy pasta water can help loosen up the noodles if they begin to dry out, and revive a dried-up sauce, turning it back into a creamy sauce. Make sure to save some before draining the pasta.

✨Substitutions & Variations
Here are a few suggestions on additional flavors to try, or simple variations to this recipe.
- No Cajun seasoning. Use creole seasoning, or you can make a quick seasoning blend of black pepper, smoked paprika, garlic powder, onion powder, cayenne pepper, oregano, and thyme.
- Add veggies. To add more vegetables to this dish, cook down tomatoes and/or red bell peppers and onions when starting the sauce. You could also stir in some fresh spinach at the end.
- Lighter option. Make a lighter cream sauce made with whole milk or half and half.
- Thicker sauce. To thicken the sauce, add some room temperature cream cheese.
- Spicier. Add more cayenne pepper, Cajun seasoning, or red pepper flakes.
- Gluten free. The only swap you'll need to make is to use a gluten free pasta, and make sure to check your store bought seasoning blends to ensure there's no gluten as well.
- Keto friendly. To make this recipe low carb and keto friendly, serve it with a keto friendly pasta of choice, or cooked spaghetti squash, or zucchini noodles.
- Use leftover (pre-cooked) chicken. For a super quick and easy meal, you can use leftover chicken, although we want to mention that the flavor won't be quite as good! Make sure to add in extra Cajun seasoning if you go this route!
🔪Prep work
- Dry chicken breasts off with paper towels.
- Mince garlic.
- Grate parmesan cheese.
- Preheat a large skillet over medium heat.
- Bring a large pot of salted water to a rolling boil for the pasta.
- Measure out all remaining ingredients.
📋Instructions
Season the chicken breasts liberally with the cajun seasoning blend and kosher salt on all sides. (Image 1)
To a hot skillet, add 2 tablespoons of butter. Add chicken, and sear on all sides over medium-high heat, until the internal temperature reaches 165°F with an instant read thermometer (affiliate link), about 5-6 minutes per side. (Image 2)
Once cooked, remove from the skillet and set aside to rest for 5-10 minutes before slicing into pieces. Don't drain any of the drippings from the skillet.
Meanwhile, cook the pasta for just a few minutes under the package instructions until it's al dente. Undercooking the pasta will make sure it doesn't get overcooked later, since the noodles will continue to cook in the sauce. *Make sure to save a cup of pasta water to thin the sauce, and for reheating purposes later.
Reduce the heat to medium, and add the rest of the butter, and a little splash of chicken broth to the skillet. Add in the minced garlic. (Image 3)
Cook until fragrant, stirring often for about 1 minute, then, immediately deglaze the pan with the rest of the chicken broth. (Image 4)
Reduce to low heat. Add in the heavy cream. (Image 5)
Stir in parmesan cheese slowly, adding in small handfuls, stirring to melt before adding the next handful. (Image 6)
Season with the remaining Cajun seasoning, and salt to taste.
Add the cooked pasta, and a little bit of pasta water, along with parsley. (Image 7)
Toss to combine, adding more pasta water until the sauce clings to the noodles. (Image 8)
Add the chicken pieces back over top, sprinkle with more parsley and freshly grated parmesan. Enjoy!
✨Tips & tricks
- Cook the chicken fresh and season it well for the best flavor. While you can use pre-cooked chicken, the flavor just won't be quite the same.
- Cook the pasta until it's al dente (cooked but still firm) to prevent it from becoming mushy. We'd recommend cooking it 1-2 minutes under the package directions. As we mentioned before, the pasta will continue to cook in the sauce.
- Heavily salt the pasta water. You want about 2 tablespoons of kosher salt per every 1 pound of pasta. The salt will flavor the noodles!
- Reserve some pasta cooking water. It's great for thinning the sauce, and for reviving leftovers the next day.
- Taste the sauce as you go and adjust the seasoning as needed to achieve the desired level of saltiness and spiciness. Especially if making this recipe for the first time, you'll want to make sure the taste is to your liking.
- To prevent the alfredo sauce from curdling or separating once the heavy cream has been added, be sure to stir it frequently and cook it over low heat. Do not boil it.
- Use freshly grated parmesan and add it slowly. Make sure each handful of cheese is melted and incorporated before adding the next. Again, low heat (or even off the heat) is your friend here.
- Let the chicken rest for a few minutes before slicing it to help keep the juices inside instead of leaking out.

This was delicious. I was a little disappointed in how thin the sauce was, but it was truly delicious. My kids (teenage boys) really loved it and gobbled it right up. One of my kids has celiac disease, and it was easy to adapt for him. Will make again! (It says it feeds 8. I would say more like 6ish).
Briana says
Hi there! Thanks so much for letting us know your thoughts about this recipe and for the feedback! I'm wondering if the sauce ended up a little thin when using gluten-free noodles? This is good feedback for us, as regular pasta tends to add more starch that thickens up the sauce a bit. You can always feel free to reduce the amount of broth next time, add more cheese, or even add a bit of softened cream cheese to make the sauce a bit thicker. I'm going to contemplate any other solutions that might work for this recipe to make the sauce thicker for those who are gluten-free. Thanks again for giving it a try!
Brittney Buell-Schneider says
This was my first time making homemade Cajun chicken Alfredo. MY GOSH…IT WAS SO, SO GOOD!!! I will say though, the prep time took me quite a bit longer than expected. Definitely make sure you have it all ready to go before you start cooking. I did however add quite a bit more Parmesan cheese to the sauce. Probably about 4-6 more ounces than what the double recipe called for. However, it tasted amazing!!! I also pre-sliced my chicken before cooking. (I like to season my food religiously. I made sure the chicken was fully coated on every slice. So, that added a little more kick to where I didn’t have to season the pasta when all mixed together.) 10/10 recommend this recipe! You will not be disappointed!
Briana says
Hi Brittney, thank you so much for all this information, and we're so glad you enjoyed it so much, that makes us so happy! Thanks for letting us know how you made yours differently. Honestly, you can't go wrong with extra parmesan! Thank you again for your kind review. 🙂
Sabrina says
If I made this using homemade pasta do you think I should completely omit the initial cooking step? I generally only cook my pasta for 3-4 minutes and it overcooks to mush so quickly so I am worried that might happen here with a double cook. Thank you so much! I am new to the site and think it looks beautiful, I can't wait to look around! 🙂
Briana says
Hi Sabrina,
Thanks for your comment! We do recommend cooking the noodles before adding them back to the sauce because there isn't enough liquid in the sauce to really get the pasta fully cooked. With that said, we'd recommend undercooking them a little bit so that they don't end up getting mushy.
Thanks also for the compliments! We work really hard on our content, we're so glad you enjoy it!:)
Cheers,
Briana & Chamere

Can you use chicken thighs instead of breast?
Briana says
Yes, certainly!
Marla says
I made this tonight and I am very happy with it! It turned out delicious. This time I used a store bought Cajun spice (Urban Accents) and I used Palmini noddles, to make it quicker and easier. Next time I will try making your seasoning blend. Thank you for sharing your recipes.
Briana says
Hey Marla, That is great to hear! We're so glad you enjoyed! Thanks so much for giving it a try. 🙂

The BEST EVER!!!! TRY IT!!

YAY! Thank you Sharon, you are awesome. So glad you like it so much!
Daralyn says
Pretty sure it should be 165F instead of 65F?
Briana says
Hi Daralyn,
Yes! You're absolutely right. Thanks for pointing that out. Just a typo!
