A creamy Cajun chicken pasta bake that’s easy, kid-friendly, and doesn’t require babysitting on the stovetop! What’s not to love?! The cozy casserole is a perfect example of a simple weeknight supper that brings the family together — even on busy evenings — and keeps you out of the kitchen.

Cajun Chicken Pasta – Easy To Make At Home

The great benefit of making your own Cajun chicken pasta at home (rather than ordering it from a restaurant like Chili’s or Applebee’s) is that you can completely control the ingredients. You can make it more or less spicy, adjust the garlic, or load it with extra veggies! Using our favorite dump-and-bake method, you’ll pull together a family-friendly one-dish meal that offers maximum flavor for minimum effort!

Ingredient Notes and Tips for Success

  • This recipe is specifically designed for and tested with rotini pasta. If you don’t have rotini, you can substitute with other short pasta shapes like penne pasta, rigatoni, or elbows. Just pick a pasta that has a similar cooking time as the rotini (about 7-8 minutes recommended on the package directions) — otherwise you’ll need to adjust the casserole’s baking time in the oven.
  • You’ll need a total of about 2 ½ cups of Alfredo sauce, which is approximately one very large 22-ounce jar or 1 ½ 15-ounce jars.
  • Use the meat from a store-bought rotisserie chicken for convenience, or cook your own chicken at home. You will need about 1 lb. of raw boneless, skinless chicken breasts (or thighs) to equal about 2 cups of cooked, shredded meat.
  • Use Cajun seasoning or Creole seasoning — both work well. Since these blends include salt, you’ll want to use low-sodium broth (or even water), and wait to add salt to your dish at the end after you’ve had a chance to taste it.

How to Make Cajun Chicken Pasta

This baked Cajun chicken pasta comes together in minutes and then the oven does the work! You’ll find detailed directions in the recipe card below, but here’s the overview:

  • In a large casserole dish, whisk together the Alfredo, broth, tomatoes, and seasoning.
  • Stir in the uncooked pasta, the chicken, and the veggies.
  • Cover and bake until the pasta is al dente, about 35 minutes. The total cooking time will vary depending on the type of pan that you use and on your individual oven. Glass or ceramic baking dishes will take longer than metal pans, for instance.
  • Once the pasta is al dente, give it a stir, add cheese on top, and bake until the cheese melts, about 5 more minutes. To know when your casserole is done, taste a bite of the pasta. The noodles should be tender and much of the liquid should be absorbed. Be careful not to overbake the casserole or the pasta will become mushy.
  • Garnish with sliced green onion or chopped fresh parsley. Serve!

Serving Suggestions

Serve this Cajun chicken pasta recipe with a house salad with candied pecans, okra and tomatoes, Southern collard greens, 3-ingredient buttermilk biscuits, Jiffy cornbread with creamed corn, 3-Ingredient sour cream muffins, or a French baguette.

Preparation and Storage Tips

  • Make Ahead: You can assemble the casserole a few hours in advance, or even leave it covered in the fridge overnight before baking. The pasta will start to soften and absorb some of the liquid as it sits, so you may need to decrease the baking time slightly.
  • Storage: This dish is best enjoyed immediately from the oven. Leftovers will keep in an airtight container in the refrigerator for 3-4 days. The pasta will dry out a bit as it sits, so you may need to stir in some additional sauce or broth when you reheat the dish. Individual portions can be reheated in the microwave for about 1-2 minutes.
  • I do not recommend freezing this casserole because pasta has a tendency to get gummy and mushy when thawed.

I just tried it and added florets from a head of broccoli. Worked fine. Great recipe.

This easy Cajun chicken pasta comes together in one dish. You don't even have to boil the noodles first!

Ingredients
  

  • 1 (22 ounce) jar Alfredo sauce (about 2 ½ cups)
  • 2 ½ cups low sodium chicken broth
  • 1 (14.5 ounce) can petite diced tomatoes, not drained
  • 1 tablespoon Cajun or Creole seasoning
  • ½ teaspoon garlic powder (or 2 teaspoons minced fresh garlic)
  • 1 (16 ounce) package uncooked rotini pasta
  • 2 cups cooked, shredded chicken (such as the meat from a store-bought rotisserie chicken)
  • 1 red bell pepper, seeded and finely diced
  • 1 green bell pepper, seeded and finely diced
  • 1 cup finely diced yellow onion (about 1 small onion)
  • 1 cup shredded mozzarella or cheddar cheese
  • Optional garnish: fresh parsley and/or sliced green onion, for garnish

  • Uncover the dish; gently stir the pasta with a fork. At this point you should check the pasta to make sure that it is al dente (firm but just about finished cooking). If it’s still too hard, cover the dish and return it to the oven until the pasta is al dente. Then move on to the next step.

Recipe Variations

  • Use andouille sausage to make a dump-and-bake Cajun sausage pasta instead, or try this Cajun shrimp and sausage pasta. For a mild dish, try this dump-and-bake chicken pot pie pasta.
  • Cooking for Two? Cut the ingredients by ¼ to get two small servings of the pasta dish. For instance, just use 4 ounces of uncooked pasta, 6 ounces of Alfredo sauce, ¾ cup of chicken broth, ½ cup diced chicken, etc. Bake in a small dish (about 5 x 6-inches) if you have one, or divide into two single-serve dishes. The cooking time will be slightly shorter, but not by much so keep an eye on it!
  • This is a great way to use up leftover turkey instead of chicken.
  • Add extra veggies if you’ve got them in your fridge, such as broccoli or zucchini.

    I love the sound of cajun chicken pasta! I’ve never made my own before, but you’re right, a lot of restaurants do have their own version. This dump and bake one sounds perfect for that kick of flavor when you’re short on time!

    1. Blair says:

      Thanks, Gayle! You should totally try this version! Great flavor for very little effort. ๐Ÿ™‚

  2. Ann Martin says:

    My family loves spicy food. This looks like a super easy dinner to make on a busy night!

    1. Blair says:

      You’ll love this version, then! Thanks so much, Ann! Enjoy!

    Hi
    I tried this recipe and though it was delicious, the sauce turned out thin and runny. Your photos how the sauce to be thick and creamy. Any idea what I might have done wrong?

    I’ve tried and enjoyed many of your recipes.

    Keep up your good work.

    1. Blair says:

      Hi, Dennis! I’m not sure — did you use penne as called for, or did you substitute with a different pasta shape? Was the pasta cooked through, or did it still need more time to finish absorbing some of the liquid? I can’t think of any other variables that would have affected the consistency of the sauce, so I’m not sure what the problem was. Sorry I don’t have a more specific suggestion.

      Thanks for reading the blog! I appreciate you following along with us! Have a great weekend!

  4. Robin Moritz says:

    Can you boil and cook pasta before baking or will they be too mushy?

    1. Blair says:

      Hi, Robin! Yes, you can definitely pre-boil the pasta in the same way that you would for a more traditional casserole. That said, you’ll have to adjust the amount of liquid that you use in the dish. When you bake the UNcooked pasta, the pasta absorbs a lot of the liquid as it bakes. If you’re starting with cooked pasta, I would suggest eliminating most of the chicken broth (maybe just set aside a little bit to thin the sauce, as necessary). Hope that helps, and enjoy!

    This has become my go to pasta during the week ! So easy to make. Thank you for sharing .

    1. Blair says:

      That’s awesome, Brittany! I totally agree — it doesn’t get much easier! ๐Ÿ™‚

  6. Karleigh says:

    Great recipe! Could you prep it all then freeze it? Or would it need to be cooked first before frozen?

    1. Blair says:

      Hi, Karleigh! You can freeze it either way — before or after baking. If you freeze it before baking, the pasta may have a slightly mushier texture after baking, but it will still be okay. Enjoy!

  8. Marion McClung says:

    I was going to make my own Cajun seasoning for this since the manufactured ones have an awful lot of salt. Then I can adjust the salt. Do you recommend a particular “recipe” for making my own seasoning?

    1. The Seasoned Mom says:

      Hi Marion! Any cajun seasoning recipe you like best will work, but this one tends to be pretty popular.

      1. Marion McClung says:

        Thanks!
