Cajun Chicken Pasta

Where do I even begin. First, this recipe has THE best Alfredo sauce recipe that you’ll ever find. (I actually got it from Olive Garden.)

The chicken is easy to season and has a perfectly golden-brown outer crust that’s super juicy on the inside.

You can use any pasta that you have on hand, and the additional ingredients that you can add is almost endless, see below!

PLUS, this meal is make-ahead and freezer-friendly. Read on!

How to Make it

*See recipe card below this post for ingredient quantities and full instructions.

Slice chicken breast in half and pat dry. Season generously with Cajun seasoning and desired amount of salt and pepper.

Sear chicken in olive oil over medium-high heat until a brown crust has formed and it’s cooked through. Set aside, let it rest for 10 minutes prior to slicing.

Melt butter to the same skillet over medium heat. Add minced garlic and cook for 1 minute.

Make-Ahead Method

  • Alfredo sauce is a convenient make-ahead and freezable sauce. Unlike some other cheese sauces, the flour in this recipe helps it to maintain it’s consistency when cooled and reheated.
  • It can be stored in the refrigerator for up to 3 days.
  • It can also be frozen and is best if used within 1-2 months.

Reheating

  • For best results, reheat leftovers in a double boiler with the lid on. The consistency, texture, and flavor is much better than microwaving. (Here’s how to make your own double boiler.)
  • Frozen sauce should be thawed overnight in the fridge before reheating.
  • It’s always best to freeze sauce by itself and boil fresh pasta before serving.
  • If the sauce is too thick when reheated, add a splash of milk or chicken broth to thin it out.

This Cajun Chicken Pasta has SUPER Creamy Alfredo Sauce, perfectly seasoned chicken, and your favorite pasta. This 30 minute meal is also make-ahead and freezer friendly!

Ingredients

  • 1 large boneless/skinless chicken breast, equal to about 1 lb.
  • 2 tablespoons olive oil
  • Salt/Pepper
  • 1 Tablespoon Cajun seasoning
  • 6 Tablespoons salted Butter
  • 4 cloves garlic, minced
  • 2 Tablespoons all-purpose flour
  • 3 cups half and half
  • ½ cup Parmesan cheese, finely grated
  • ½ cup Romano cheese, finely grated
  • ¾ pound pasta

Instructions

  • Pro Tip: Let the grated cheese and half and half come to room temperature prior to adding to the sauce.
  • Bring a pot of salted water to a boil. As it gets up to temperature, prepare the chicken.

Sear the Chicken

  • Slice chicken breast in half lengthwise and pat dry. Season generously with Cajun seasoning and desired amount of salt and pepper.
  • Heat olive oil in a skillet over medium-high heat. Add chicken and let it sear, undisturbed, for about 5 minutes on each side, until a brown crust has formed and the chicken is cooked through. Set aside, let it rest for 10 minutes prior to slicing.
  • Add the pasta to the boiling water and cook according to package instructions. Meanwhile, prepare the sauce.

Prepare the Sauce

  • Melt butter to the same skillet over medium heat. Use a silicone spatula to scrap up any brown bits from the bottom of the pan. This will give the sauce plenty of flavor. Add minced garlic and cook for 1 minute.
  • Whisk in the flour and heat for 30 seconds. Slowly add the half and half.
  • Reduce heat to low. Gradually sprinkle in the Parmesan and Romano cheese, whisking to incorporate.
  • Add the drained pasta. Use kitchen tongs to toss and incorporate into the sauce. The sauce will continue to thicken upon standing.
  • Add the sliced chicken and toss to incorporate into the sauce allow it 1-2 minutes to heat through.
  • Remove from heat and serve with homemade garlic bread.

Notes

Optional Additions

  • 1-2 Tablespoons Hot Sauce

  1. I am planning on making this for dinner tonight and I would love to add shrimp! 
    What would be the steps to add that? 
    Thank you! 

  2. This was a huge hit with my husband and his parents. Great flavor and pretty easy to make

  3. Best Cajun Alfredo I’ve ever had and so easy! Also made with gluten-free flower and fettuccine and it’s perfect!

    • This makes me so happy to hear Maria! I love the flavors of this one. Thanks so much for the great comments and for taking the time to leave a review!❤️

  4. Looking to freeze this dish as a whole my friend is having surgery and will not be able to cook I live too far away to make this fresh for her. Would it be okay to freeze everything together and do you have any tips for freezing and reheating altogether? 

    • Hi Ashley! You can make this meal, let it cool completely, and freeze it either as a whole or in portion sizes. Your friend would then want to let it thaw completely, and then I would recommend reheating it in a makeshift double boiler for the best results. Since this is a cream sauce it’s a better way to ensure that it gets restored back to it’s original consistency as much as possible. I also have a selection of freezer food here that you can look through. My Chicken Broccoli Rice casserole is a great meal to prepare ahead of time and freeze, then bake when ready to eat.

  5. Had this for dinner tonight and it was amazing! I served the chicken on the side because I can’t do spicy but my husband loves it so I did part of it without the Cajun seasoning. We loved it. Thanks for sharing. Comments on the buttermilk biscuits as well.

    • Sounds like you pulled off another great meal Diane, nice work!🙌 I love making some extra with this one since leftovers are so yummy😋. Thanks so much for your support!
