Cajun Chicken Pasta Alfredo

Me and one pot meals are BFF’s lately. How nice is it to only dirty one pan and have a delicious and hearty meal for dinner?

They are fast, easy, and my family went crazy over this one!

It all started at Chili’s with my love for Cajun Chicken Pasta.

I actually have a dang good copycat recipe here on the blog. I order every time, and my boys do too!

So I was thinking one day. Why don’t I make this recipe in one pot that is quick and easy? So I did. And it was awesome.

The cajun flavor added so much flavor to this one pot meal. It added just the right amount of kick to the creamy alfredo sauce. It was amazing!

I loved throwing everything into the pot. Covering it for about 12 minutes and dinner was ready.

The cajun wasn’t too spicy for the kids either. They gobbled it down.

Quick. Easy. One Pot. Delicious. I call this meal a success!

What you need to make cajun chicken Alfredo pasta

This is a tried and true recipe that I can’t get enough of.

I love all the flavor combinations, fettuccine with chicken mixture and everything all in one pot!

It is a huge win for me.

Most ingredients you already have on hand and ready to go!

We love to make this recipe on a busy weeknight. It has never failed us.

30 minutes and we are all at the table together enjoying our meal.

  • Olive oil: this helps cook your chicken, adds a nutty flavor and prevents the chicken from sticking to the pan.
  • Boneless skinless chicken breast: cut into bite size chunks.
  • Cajun seasoning: you will love the flavors of cajun seasoning over top. This will be divided for you so it is not too powerful for kids.
  • Garlic cloves: minced and always brings on that subtle garlicky flavor.
  • Chicken broth: more of a salty flavor but this will help bring in more juices and tenderize the chicken and pasta.
  • Half and half: rich and creamy cream that will thicken the Alfredo Sauce.
  • Salt and Black pepper: just a pinch!
  • Garlic powder: add in the garlicky flavoring to this one pot meal.
  • Fettuccini pasta: thick, rich pasta that is best for soaking up Alfredo Sauce but not overpowering the chicken.
  • Grated parmesan cheese: blends right in and adds a rich cheesy flavor to the overall meal.

How you make cajun chicken Alfredo pasta

This is basically a basic type of recipe.

Cook your chicken, cook your noodles and mix it all together with seasonings and creamy deliciousness.

Chicken does not take long to cook through and your fettuccine noodles are even easier to cook.

I love the smell of the chicken and olive oil cooking together and then adding in the cajun seasoning and garlic just is a real hit.

Alfredo Sauce is one of my favorites too! If you are looking for more Alfredo Sauce recipes click here.

  • Prepare and cook your chicken: Heat the oil in a large pot over medium high heat. Add the chicken and season with 1 teaspoon cajun seasoning. Cook until the chicken is cooked throughout and no longer pink in the center. Add the garlic and continue cooking for 1 minute.
  • Prepare and cook fettuccine: Add the broth, half and half, 1 teaspoon cajun seasoning, salt, pepper, and garlic powder to the pot. Break the fettuccine noodles in half and add them to the pot.
  • Cook noodles and chicken together: Cover and bring to a rapid boil. Reduce heat to medium low and continue to cook for 10-12 minutes or until the noodles are al dente and there is only about ¼ inch of liquid along the bottom.
  • Add parmesan cheese: Remove from heat and stir in the parmesan cheese. Serve immediately.

Tips for Cajun Chicken Alfredo Pasta

This cajun chicken Alfredo Pasta is straight forward and precisely perfect in most ways.

It is hard to substitute most things or add in other seasonings since it is mastered with those ingredients.

Here are some variations and tips to making the perfect cajun chicken Alfredo Pasta combination.

If you need to substitute anything just be sure that it will alter the taste, texture and even some of the meal.

  • If you are in a hurry, tenderizing your chicken breast by rolling or pounding it to make it thinner will help speed up the cooking process. I do not recommend this though. Thick chunks of chicken are a big hit with this meal.
  • If you are a cajun lover like me, when preparing your chicken you can directly rub your cajun seasoning on the chicken before you cook it.
  • Make sure that your oil in your one pot pan is hot before adding your chicken.
  • Substituting half and half for whole milk and light or heavy cream will work if you don’t have half half.
  • Al dente means that it is cooked firm or until done.
  • You will want your pasta cooked al dente in the sauce. It will continue to cook as the sauce thickens and it is on the stove top.
  • Love another type of pasta?! Penne or bowtie even are great substitutes to this one pot meal.

Storing cajun chicken Alfredo pasta

You will enjoy how easy this cajun chicken Alfredo Pasta is to make. It is one of kind and so delicious!

Every bite is going to have a sweet, savory and a kick of spice to complete this meal.

All you need in one complete meal.

You can make this ahead of time but it is best served right away after you add your parmesan on top.

When warming up you will see a separation in sauce and noodles.

I ensure you by slowly warming up the pasta and stirring continuously it will look back to normal.

  • Making ahead: Usually you will leave out the pasta when making ahead and adding that when warming up. In this case, that is the main ingredient. You will want to make it as is according to the recipe and put in pre-made Tupperware or an airtight container in the refrigerator until ready to serve. You can also let it sit on the stove top on low to keep warm, stirring it occasionally. Just add the parmesan right before you serve it.
  • Refrigerating: Same as making ahead. You will make this according to the recipe and add this to an airtight container to store in the refrigerator for 3 to 5 days.
  • Freezing: Unfortunately, this recipe is not the best for freezing. It can be done but you will need to be careful when warming up. This will be cooked and cooled completely. Add the chicken pasta into a freezer container and freeze for up to one month.
  • Warming up: This is the key to warming up the pasta: SLOWLY. haha. The slower, the better. It is quick to make but slow to warm up. You do not want the Alfredo to separate and have a hard time getting to combine again. Warm on low over the stovetop for best results, stirring it until it is warm and combined sauces. If you are in a hurry and need to use a microwave, warm up in 1 minute intervals. Stirring after every minute. Garnish with a little more parmesan cheese and stir together. Enjoy!

  1. this was amazing!!! My kids loved it, even the picky-eater ate two servings. Will be making this again 🙂

  2. I’m a saucy kinda of woman, would it hurt the taste of this recipe if I doubled the sauce?

  3. This recipe has great flavor! I just can’t seem to get the sauce/pasta right though. If I cook it for the full 12 minutes (which is how I like my pasta – not al dente), then there is nothing left of the sauce. If I cook it for less time until there is just enough liquid left in the bottom, the pasta isn’t done. Do you have any recommendations? Add a bit more to the sauce maybe?

  4. Making this soon! One question—what kind of Cajun seasoning do you use? Does it have salt in it, like Tony Chachere’s Cajun Seasoning? Thanks!

  5. I love one pot meals! When you make everything in one pot it’s just so simple and easy. I love to cook but sometimes I don’t want to get all fancy and chop all the veggies and cook one thing, and put one thing in one bowl then another, and you get my drift I am sure. My sister came over to do her laundry so this was as good a time as any to make this. Everyone loved it! My sister, who is a big eater, had 3 bowls full! I had one and a half bowls. Mom likes a little pasta with her sauce and for her there wasn’t enough sauce. We have only a little leftovers so I will make more sauce for her. She said it was very tasty! This is definitely a keeper!

    1. Forgot to say that I had made some of Emeral’s Seasoning but I cut down on some of the spices that were to hot for me. I added bacon, about 3 slices of diced cooked and some tasty tiny baby leftover frozen peas. Since they were already cooked I added them at the end so we didn’t have mush. It was even more yummy with the added ingredients and besides, everything is better with bacon!

  6. This stuff is AMAZING! I have made it for the last 3 nights due to a sinus infection. My 3yo doesn’t like it (too spicy) but hubs and I both do! I love that it only takes one pan. Also, the chicken is easily omitted.

  7. Made this tonight and after reading the comments, I doubled the sauce and added a little extra noodles. I also cooked the noodles 20 minutes instead of 12, since my husband likes them well done. I have to say this was a hit! We love Cajun alfredo when we go out, and I’m excited to have a great recipe for home. Thanks! !

  8. I’ve made this several times now, and it’s become one of my favorites for an easy, tasty, and very satisfying meal. I did want to get some veggies in there, so I chopped up some broccoli and tossed it in the pot for the last five minutes or so–it’s a really tasty addition!

  9. Hello! This looks simple and delicious but I have a question before I can make it: we don’t have half and half in the UK. What would you recommend as a substitute?

    1. Half and half is just half milk and half heavy cream. You can substitute with a higher fat content of milk to still get the creaminess of the sauce.

  10. This recipe is tasty and in the spirit of cooking more food for more people, I [exactly] doubled this recipe.
    It scales just fine except for the black pepper and perhaps the salt, as the black pepper overpowered the Cajun spice (Tony Chachere in this case). Some loved the black pepper tongue-burn, most did not. Plus many Cajun spices have a fair amount of salt anyway (looking at you “Slap Ya Mama”).

    In the subsequent, doubled, preparation, I reduced the amount of black pepper and salt by a third each, and the food was just right for the crew. Those who wanted tongue-burn were easily able to add more black pepper on their own.


  11. Just made it for dinner! It’s great and very simple. Because cajun seasoning and chicken broth already has salt, I choose not to add anymore. Also, I brought mine to a boil with the lid then removed the lid while it simmered. The sauce is pretty deceptive as it becomes very thick when it cools (YUMMY). Lastly, I did add some juice of a lemon, lemon zest, and cilantro to brighten up the flavor. Because I’m a veggie junkie, I think I’ll add some steamed broccoli right before serving next time.

  12. For 6-8 people… double everything except salt, pepper, and cajun seasoning. Could cut salt down to 1/2 tsp total for double recipe. I used slap yo mama cajun seasoning. I also used 4 cups broth for double recipe because that is how much was in the container. We like spice, but with everything doubled it was too peppery and too spicy. Great consistency and flavor. From the picture you can’t tell how creamy it is. Very good. Thank you. Will make again with changes.

  13. Great recipe! I doubled the sauce and added more noodles because we wanted more! Also added shrimp, mushrooms and topped with green onions. Both the kiddos loved this. Thanks for the great and easy recipe!

  14. I have made this with the chicken and it was delicious but was wondering….Could I make this without the chicken? Just the cajun alfredo pasta? Would I just said the garlic and then add the chicken broth and continue recipe? Thanks!

  15. Hi! I’m going to make this tonight!
    I have a couple of quick questions…

    1. In step three, after it reaches a boil, do I keep the pot covered while it simmers for 10 to 12 more minutes?

    2. Does the chicken boil/simmer for the 10-12 minutes with the pasta and liquid? I’m worried the chicken would be over cooked?

    Thanks so much for helping me out!

    1. Hi Heather,

      1. Yes, leave your lid on to simmer.
      2. Once your chicken reaches an internal temperature of 165 degrees Fahrenheit then add in all your ingredients leaving the chicken in the pot. The sauces will keep it moist and soft.

  16. 5 stars
    This is the easiest but most delicious meal I’ve made in a long time!! We had shrimp on hand so I started the shrimp, pulled them out and then threw them back in at the end. It was phenomenal!

  17. Made this the other night for dinner. Absolutely fabulous. Tasty and light compared to other alfredo recipes!

  18. 5 stars
    This was DELISH!!! Next time I have to double the sauce and because of the kiddos, will try 1 tsp Cajun. I think would be more delicious without the chicken!

  19. 5 stars
    Used tempeh instead of chicken and vegetarian “chicken” broth and it came out amazing! I also added mushrooms when adding the dry pasta. At the end, when adding parmesan cheese, I also added two big handfuls of spinach. My family really liked it!!! In the future, b/c my vegetarian chicken broth has salt, I will omit the teaspoon of salt. Also, I think it tasted great even before the parmesan cheese was mixed in! Thank you for a great, simple recipe! 🙂

  20. Is there an instant pot recipe for this? I make this quite often and it is delicious! But I would like to try it in the instant pot

  21. This was such good recipe. My husband went back for second and that never happens when I cook. Thank you.

  22. Just divine— and easy clean up! I replaced the chicken with andouille sausage, and it was just as good!
