We’re all about comfort food around here. Bonus points if it’s super simple to make with super simple kitchen staples, right?! This cajun chicken alfredo is one of those meals that we make over and over again. It’s one of the most popular recipes on our site and Pinterest. We’re so glad so many people have had the chance to enjoy it, and make it time and time again. We used chicken breasts for this recipe, but you could most definitely use chicken thighs if you prefer. The key is rubbing the chicken with our super delicious cajun inspired seasoning blend. (Check out the recipe later on in this post!)

If you’re looking for an easy to make, customizable dinner, make up a batch of this cajun chicken alfredo. You can prepare separate noodles and/or noodle replacements on the side! For instance, you can make spaghetti squash for those that follow a low carb diet, or regular noodles for you carb loving friends and family. Either way, you’re going to have something that everyone will enjoy! You can skip to the recipe card if you wish, if you want to get straight to it. Please note that we’ve also answered many questions about substitutions and more in the body of the post, so make sure to have a look at those if you have questions. Please feel free to let us know your thoughts in the comments!

Here’s What We Used For This Cajun Chicken Alfredo:​

For the Cajun Chicken Alfredo:

Homemade cajun seasoning blend- You can definitely use store bought cajun seasoning if you prefer. However, our homemade seasoning blend just makes everything taste so good. Making your own cajun seasoning allows you to control the spice level, salt level and it’s cost effective too! Keep reading for our super easy homemade cajun seasoning blend. **Please note, the seasoning recipe we provide is meant to be for a large batch, not used all at once!

Unsalted butter– We love using unsalted butter because it’s much easier to control the salt level in this dish. Since our seasoning blend already has salt in it, we want to control the other potential salty ingredients as much as we can. Parmesan cheese is another one of those naturally salty ingredients. We opt for unsalted butter to help us control what’s going in this dish!

Chicken breasts or thighs– As we mentioned above, we usually use chicken breasts, but chicken thighs would be wonderful as well. Leftover rotisserie chicken would work as well, but you may want to heat it up in you skillet with a little butter and lots of your cajun seasoning blend since you won’t be adding blackened chicken to the sauce.

Fresh garlic– Since there are so few ingredients in this dish, we highly recommend using freshly minced garlic to flavor your sauce. You could use jarred minced garlic or garlic powder if you want, but we think the fresh garlic is truly what you want for this.

Chicken broth – This thins out our sauce and adds a lot of flavor. It’s only natural to use chicken broth since this is a chicken dish. You can however use whatever you have on hand. Often we like to use this Pacific Foods Chicken Bone Broth to put even more flavor, protein and nutrients into this dish. Feel free to use chicken bouillon with a little water if that’s all you have on hand.

Heavy whipping cream- This is what makes our keto cajun chicken alfredo sauce rich and creamy! We suppose you could use half and half instead, but trust us, you want the heavy whipping cream. The flavor is unmatched, and truthfully that’s what makes this an alfredo sauce. We think it’s a pretty essential ingredient.

Parmesan cheese – Okay again, there aren’t many ingredients in this dish, so use the good stuff if you can get it. Pre-shredded can be convenient but it doesn’t melt very well, so if you can, get a block of parmesan and grate it up. Grating your own parmesan is going to be really helpful to get that velvety, luscious and creamy smooth sauce. Nobody wants chunky bits of parmesan cheese in the sauce!

Noodles of choice – We actually opt for a keto friendly noodle replacement, like spaghetti squash, zucchini noodles, or any low carb noodle replacement. We love our Healthy Noodles from Costco or Great Low Carb Noodles (so good!) If you aren’t concerned with carbs, just use your favorite pasta. Just make sure to add them into your nutrition facts later.

Fresh parsley– Optional, but a little parsley adds some color to this quite orange-ish yellow dish, plus it adds some freshness and lightness to this pretty heavy dish. If you don’t have fresh, you could always use dried as well. If you don’t like parsley, well, free to skip it!

What Noodles or Noodle Replacement Should I Serve This With?

Totally up to you, but we love using baked spaghetti squash, zucchini noodles, or some Healthy Noodles from Costco. We also just recently tried some elbow macaroni noodles from Great Low Carb and fell in love (this is a totally unsponsored opinion, we bought it with our own money and it’s not cheap, but WORTH IT!) Here’s a variety pack on Amazon. It includes some fettuccine, penne, elbow, and rotini noodles which would all work very well for this.

If you aren’t counting carbs, don’t worry, just use whatever you want and report back with how you enjoy this recipe! 🙂

**Please note, that for this recipe, we didn’t include any noodle or noodle replacements in the nutrition facts, because there are so many different options to choose from. We used spaghetti squash for our noodle base, but you could use whatever you’d like. As always, we list out the full nutrition facts in our recipe card below.

Can I Cook This In A Cast Iron Skillet?

Yes, absolutely! We absolutely love our Lodge Cast Iron cookware and we use it for everything. This recipe is no exception. Most of our recipes are one skillet dishes. We absolutely love cooking with cast iron. It’s so versatile, and it means less dishes! You do need to take quite good care of your cast iron cookware, but we promise that it’s super easy to do so. If you’re looking for ways to better care for your Lodge Cast Iron cookware, we made a very thorough guide with a tutorial video here.

What’s The Best Cajun Seasoning and How Do I Make My Own?

The spice mix we use for this recipe is our go-to, but you could certainly use any cajun spice blend you like. We premix a batch ahead of time, then it’s always ready to go in our pantry. Just be aware that some store bought blends may have a much higher sodium content, so this can affect the flavor. We’d also like to mention that this seasoning blend is quite spicy, as we prefer most of our food to be, so keep this in mind when making your blend.

We’d like to mention that this recipe for cajun seasoning is meant to be a LARGE batch. DO NOT use it all for this one recipe! One of our followers over on Instagram told us they accidentally did that, and we felt so bad. As much as we love spice, using this whole batch of cajun seasoning not what you want to do. To make this seasoning blend, simply combine all the spices in a bowl, then and store in a jar for later use. For this recipe will use about 1 – 1.5 tablespoons of this seasoning blend.

What Chicken Should I Use For This Cajun Chicken Alfredo?

You can use whatever your favorite cut of chicken is for this. We do often use chicken breasts, but chicken thighs are also amazing. Truthfully, we use what we have on hand! If you want to shred up some rotisserie chicken for this that would be really delicious. If you want you could sear the rotisserie chicken with a little bit of butter and a good amount of cajun seasoning to give it some good flavor. Let us know what you end up using in the comments!
