How to Make Crock Pot Cajun Chicken Alfredo Recipe
Step 1: Sear the Chicken
Begin by patting the chicken breasts dry to ensure a nice sear. Season them generously with salt, pepper, and garlic powder—this simple seasoning sets the cornerstone for flavor. Heat olive oil in a large pan over high heat and brown each side of the chicken. This quick sear locks in juices while creating a beautiful crust, but don’t worry about cooking through completely because the slow cooker will finish the job.
Step 2: Combine and Slow Cook
Once seared, add the browned chicken to your slow cooker along with sliced smoked sausage, heavy cream, chicken broth, butter, garlic cloves, Cajun seasoning, and the remaining salt and pepper. Set your slow cooker to low and let it work its magic for four hours. The long, slow simmer melds the spicy Cajun flavors with the creamy sauce and tender meats, creating a rich and comforting base for your pasta.
Step 3: Prepare the Pasta and Slice Chicken
About 30 minutes before the cooking time is up, carefully remove the chicken breasts and let them cool slightly. Slice them into bite-sized pieces while you add the uncooked penne pasta directly into the slow cooker. Increase the heat to high and cook for another 30 minutes. The pasta will absorb all those fantastic flavors from the sauce, becoming tender without turning mushy.
Step 4: Finish with Parmesan and Assemble
When the pasta is perfectly cooked, stir in the shredded parmesan cheese which will melt into the sauce, offering a gorgeous, cheesy finish. Finally, top the dish with your sliced chicken pieces, allowing each bite to have a balance of creamy sauce, smoky sausage, and tender chicken. Your Crock Pot Cajun Chicken Alfredo Recipe is now ready to serve and savor!
How to Serve Crock Pot Cajun Chicken Alfredo Recipe

Garnishes
To elevate this dish, sprinkle freshly chopped parsley or green onions on top right before serving. These fresh garnishes not only add a pop of color but also provide a slight brightness that balances the creamy richness perfectly. A dash of extra parmesan or a squeeze of lemon can also brighten and enhance layers of flavor beautifully.
Side Dishes
This Crock Pot Cajun Chicken Alfredo Recipe pairs wonderfully with simple, fresh sides to cut through the richness. Think crisp green salads with a light vinaigrette, roasted vegetables like asparagus or Brussels sprouts, or even a crusty garlic bread to soak up every last bit of sauce. These sides keep the meal balanced and satisfying.
Creative Ways to Present
For a fun twist, serve this creamy Cajun classic over a bed of steamed rice or creamy mashed potatoes instead of pasta. You can also layer it in a casserole dish topped with breadcrumbs and bake it for a golden, crispy crust. This flexibility makes the recipe a perfect weeknight go-to or a show-stopping crowd-pleaser at dinner parties.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 to 4 days. Because this dish is so creamy, make sure it’s cooled before sealing the container to keep the sauce thick and luscious when reheated.
Freezing
You can freeze the Crock Pot Cajun Chicken Alfredo Recipe, but it’s best to freeze without the pasta added as it can become mushy when thawed. Freeze the sauce and meats in a freezer-safe container for up to 2 months. When ready, thaw overnight and cook fresh pasta to mix in before serving.
Reheating
Reheat gently on the stovetop over low heat, stirring frequently to prevent the cream from separating. Add a splash of chicken broth or heavy cream if the sauce seems too thick. This will restore the creamy texture and help it warm evenly, making every bite taste as fresh as the first.
FAQs
Can I use chicken thighs instead of chicken breasts?
Absolutely! Chicken thighs tend to stay juicier and can add a bit more flavor, especially when slow-cooked. Just adjust the cooking time slightly if needed to ensure they are tender and cooked through.
How spicy is this Crock Pot Cajun Chicken Alfredo Recipe?
The Cajun seasoning adds a nice, medium-level heat with some smoky undertones. If you prefer it milder, you can reduce the Cajun seasoning by half or adjust to your taste. For extra heat, add a pinch of cayenne pepper or some sliced jalapeños.
Can I make this recipe in an Instant Pot?
Yes! You can adapt this recipe by searing the chicken using the sauté function, then cooking all ingredients under pressure for about 15 minutes, followed by adding pasta and pressure cooking a few more minutes. Just keep an eye on the liquid ratios since Instant Pots cook much faster.
What pasta works best in this recipe?
Penne is ideal because its tube shape holds onto the creamy sauce wonderfully, but you can substitute with rigatoni, rotini, or even farfalle depending on what you have on hand. Just be sure to use a sturdy pasta that won’t turn mushy.
Is it possible to make this recipe dairy-free?
You can swap heavy cream and butter for coconut cream or a dairy-free butter alternative and use a dairy-free cheese substitute. Keep in mind this may change the texture and flavor, but the dish will still be delicious with that Cajun flair.

Trust me when I say that this Crock Pot Cajun Chicken Alfredo Recipe has the power to become a fast favorite in your kitchen.

Description
This Crock Pot Cajun Chicken Alfredo is a hearty, creamy slow-cooked dish that combines tender Cajun-seasoned chicken, smoky sausage, and penne pasta simmered in a rich Alfredo sauce made with heavy cream and parmesan cheese. Perfect for a comforting family meal with minimal hands-on cooking.
Ingredients
Proteins
- 1 pound boneless skinless chicken breasts
- 1 pound smoked sausage, sliced into 1 inch pieces
Dairy
- 3 cups heavy cream
- 4 tablespoons butter
- 8 ounces shredded parmesan cheese
Pantry Items & Seasonings
- 1 tablespoon olive oil
- 4 cups low sodium chicken broth
- 2 tablespoons Cajun seasoning
- 2 cloves garlic, minced or whole as preferred
- 1 teaspoon garlic powder
- 1.5 teaspoons salt, divided
- 1.5 teaspoons black pepper, divided
Pasta
- 1 pound uncooked penne pasta
Instructions
- Season and Sear the Chicken: Pat the chicken breasts dry and season them with 1 teaspoon of salt, 1 teaspoon of black pepper, and the garlic powder. Heat olive oil in a large skillet over high heat and sear the chicken pieces until browned on both sides but not fully cooked. This helps lock in flavor and texture.
- Combine Ingredients in Slow Cooker: Transfer the seared chicken to an 8-quart slow cooker. Add sliced smoked sausage, heavy cream, low sodium chicken broth, butter, whole or minced garlic cloves, Cajun seasoning, and the remaining 1/2 teaspoon salt and 1/2 teaspoon pepper. Stir gently to combine all ingredients evenly.
- Cook on Low Heat: Cover and cook the mixture on low heat for 4 hours. This slow cooking process tenderizes the chicken and allows the flavors to meld thoroughly.
- Prepare Chicken and Add Pasta: About 30 minutes before the cooking time ends, remove the chicken breasts from the slow cooker and let them cool slightly. Slice the chicken into bite-sized pieces. Add the uncooked penne pasta directly into the slow cooker and increase the heat setting to high. Cook uncovered for an additional 30 minutes, or until the pasta is tender and has absorbed the flavors.
- Finish with Parmesan Cheese and Serve: Once the pasta is cooked, stir in the shredded parmesan cheese until melted and creamy. Top the dish with the sliced chicken. Serve warm for a delicious, creamy Cajun-inspired Alfredo meal.
Notes
- Make sure not to overcook the pasta in the slow cooker to avoid it becoming mushy; check pepper for seasoning at the end and adjust if necessary.
- Use low sodium broth to control the saltiness of the dish, especially since the sausage and cheese contribute salt.
- If you prefer a spicier dish, add more Cajun seasoning or include a pinch of cayenne pepper.
- Leftovers can be refrigerated for up to 3 days and reheated gently on the stovetop or microwave.
- For a lighter version, substitute half-and-half for heavy cream, but the sauce will be less rich.
