Ingredients You’ll Need
This recipe calls for a handful of simple, fresh ingredients that each play a crucial role in building layers of flavor, texture, and color. Everything from the seasoning to the veggies is essential for creating that authentic Cajun taste and creamy finish.
- 1 ½ pounds boneless skinless chicken breasts: The star protein that soaks up the Cajun spices beautifully for tender results.
- 1 tablespoon Cajun seasoning: Brings the signature smoky, spicy flavor typical of Cajun cuisine.
- 1 teaspoon paprika: Adds earthiness and vibrant color to the chicken.
- ½ teaspoon garlic powder: Enhances savoriness and depth of taste.
- ½ teaspoon onion powder: Complements the fresh onions and boosts umami.
- ½ teaspoon salt: Balances and intensifies the seasonings.
- ¼ teaspoon black pepper: Provides a subtle bite without overpowering the dish.
- 1 red bell pepper (sliced): Contributes sweetness and crunch along with a pop of bright color.
- 1 green bell pepper (sliced): Adds freshness and a mild bitterness that balances spice.
- 1 small yellow onion (sliced): Gives a sweet and savory base flavor as it softens.
- 3 cups low-sodium chicken broth: Ensures the chicken stays moist while cooking and creates a flavorful cooking liquid.
- 8 oz penne or rotini pasta: Perfect shapes for holding onto the creamy sauce once added.
- 1 cup heavy cream: Delivers the luxuriously rich and creamy texture this pasta deserves.
- ½ cup grated Parmesan cheese: Adds sharp, nutty flavor that melts into the sauce beautifully.
- 2 tablespoons cornstarch mixed with 2 tablespoons cold water (optional): Use this slurry if you want a thicker, clingier sauce.
- Fresh parsley for garnish: A fresh herbaceous finish for color and brightness on top.
How to Make Crock Pot Cajun Chicken Pasta Recipe
Step 1: Season and Layer the Ingredients
Start by seasoning your chicken breasts thoroughly with Cajun seasoning, paprika, garlic powder, onion powder, salt, and black pepper. This blend of spices really sets the tone for the dish, infusing the meat with deep flavor. Place the chicken at the bottom of your crock pot and layer the sliced red and green bell peppers along with the yellow onion on top. Pour in the chicken broth, which will keep everything juicy as it simmers.
Step 2: Slow Cook to Perfection
Cover and cook the mixture on low for 4 to 5 hours or on high for 2 to 3 hours. Patience here is key because this is what allows the chicken to become incredibly tender and the flavors to meld together wonderfully. Once cooked, remove the chicken breasts and shred them finely with two forks before returning the shredded chicken back into the crock pot for the next step.
Step 3: Add Pasta and Creamy Ingredients
Next, stir in the uncooked pasta, heavy cream, and Parmesan cheese. If you prefer a thick sauce, toss in the cornstarch slurry at this point. Cover again and cook on high for 20 to 30 minutes or until the pasta reaches a tender texture. Stir occasionally to prevent sticking and ensure even cooking. This step transforms the broth into a luscious, creamy sauce that coats every nook of pasta and tender chicken bite.
Step 4: Final Touches and Seasoning
Once the pasta is cooked, taste your creation and adjust any seasonings as needed—maybe a pinch more salt or an extra dash of Cajun seasoning to amp up the flavor. Garnish generously with fresh parsley to add a fresh, green pop that lifts the entire dish.
How to Serve Crock Pot Cajun Chicken Pasta Recipe

Garnishes
A sprinkle of freshly chopped parsley is a simple yet beautiful garnish for this dish. It adds just the right fresh touch to contrast with the creamy, spicy pasta. You can also add a few grates of Parmesan on top for extra cheesiness and a squeeze of lemon juice if you want a subtle tang that brightens the richness.
Side Dishes
This hearty Crock Pot Cajun Chicken Pasta Recipe pairs wonderfully with crisp, refreshing sides. Consider a green salad with a citrus vinaigrette or roasted vegetables to balance the creaminess. Garlic bread or crusty French bread is also fantastic for soaking up that flavorful sauce.
Creative Ways to Present
For a festive meal, serve this pasta in individual bowls topped with extra parsley and a slice of lemon on the side. You can even sprinkle some crushed red pepper flakes for guests who like it hotter. If you’re entertaining, serve alongside a Cajun-spiced shrimp appetizer to keep the theme going strong.
Make Ahead and Storage
Storing Leftovers
Leftover Crock Pot Cajun Chicken Pasta Recipe keeps well in the refrigerator for up to 3 days. Store it in an airtight container to preserve moisture and flavor. The creamy sauce might thicken up a bit overnight, but a quick stir with a splash of broth or cream brings it back to life.
Freezing
This dish freezes nicely for up to 2 months. Use freezer-safe containers or bags, leaving some space for expansion. When you’re ready to enjoy it again, thaw overnight in the refrigerator to help the textures remain intact and avoid watery sauce after reheating.
Reheating
Reheat leftovers gently on the stovetop over low heat, stirring often and adding a little chicken broth, cream, or milk to loosen the sauce if necessary. Avoid microwaving at full power to preserve the creamy consistency and avoid drying out the chicken.
FAQs
Can I use frozen chicken for this recipe?
Yes, you can use frozen chicken breasts, but you should increase the cooking time slightly and ensure the chicken reaches a safe internal temperature before shredding and adding pasta.
What can I substitute for heavy cream?
If you want a lighter option, half-and-half or even whole milk can be used, but the sauce will be less rich and creamy. For a dairy-free version, coconut milk works well but will add a distinct flavor.
Is this recipe gluten-free?
This Crock Pot Cajun Chicken Pasta Recipe can easily be made gluten-free by using gluten-free pasta. Just watch the cooking time for the pasta to avoid overcooking.
How spicy is this dish?
The spice level is moderate thanks to the Cajun seasoning, but feel free to add cayenne pepper or jalapeños if you want to turn up the heat to your liking.
Can I prepare this dish in advance?
You can prep the ingredients the day before and store in the refrigerator, then add to the crock pot when ready. However, it’s best served fresh after cooking the pasta to maintain the perfect texture.
