Crock pot creamy Cajun chicken pasta is the perfect combination of tender chicken, rich and creamy sauce, and a little spicy kick from Cajun seasoning. This dish is a one-pot wonder where the flavors all blend together beautifully while cooking slow and easy, making it super convenient for busy days.
I love how this recipe lets the slow cooker do all the work while filling the house with the most inviting aroma. The creamy sauce thickens perfectly by the time the chicken is juicy and tender, and the Cajun spices add just the right amount of heat to make every bite exciting without being overwhelming. It’s totally comforting but still has that little spark that keeps you coming back for more.
My favorite way to serve this is straight over some warm pasta or even tossed with fresh veggies or garlic bread on the side. It makes for a hearty meal that feels a little special but doesn’t need any fuss. Whenever I make this, it’s a hit with the whole family, and there’s usually some happy second helpings happening around the table!
Key Ingredients & Substitutions
Chicken breasts: I like using boneless, skinless chicken breasts for tender meat that cooks evenly in the crock pot. You can also swap with thighs for richer flavor and more moisture.
Cajun seasoning: This is the star for adding that spicy, smoky kick. If you don’t have Cajun seasoning, a mix of paprika, garlic powder, onion powder, cayenne, and oregano works great.
Heavy cream: It creates the creamy texture and rich sauce. For a lighter option, use half-and-half or coconut milk, but the sauce won’t be as thick or creamy.
Pasta: Fettuccine or linguine is ideal since it holds the sauce well. You can use penne or rigatoni if preferred—just watch cooking times when adding to the crock pot.
Parmesan cheese: Provides a cheesy depth and helps thicken the sauce. If you want to change it up, Pecorino Romano or Asiago are tasty substitutes.
How Do I Prevent The Pasta From Getting Mushy in the Crock Pot?
Cooking pasta directly in the crock pot can be tricky because it might turn mushy if cooked too long.
- Add uncooked pasta only after the chicken is fully cooked and shredded.
- Pour in heavy cream and stir with the pasta so it’s coated in sauce.
- Cook covered on high for 30-40 mins, stirring occasionally to prevent sticking.
- Check pasta often and remove from heat as soon as it’s al dente to avoid overcooking.
Stirring is key here—it helps pasta cook evenly and keeps it from clumping. With these tips, you get tender, perfectly creamy pasta that soaks up the Cajun flavors without getting mushy.
Equipment You’ll Need
- Crock pot – This slow cooker makes the dish hands-off and lets flavors meld over time without extra effort.
- Skillet – Great for searing the chicken to lock in flavor and add a nice crust before slow cooking.
- Wooden spoon or heatproof spatula – Perfect for stirring pasta in the crock pot without scratching it.
- Knife and cutting board – For slicing onions, garlic, and chopping parsley easily and safely.
Flavor Variations & Add-Ins
- Swap chicken for shrimp or sausage – Shrimp cooks quickly and adds a seafood twist; sausage boosts smoky richness.
- Add bell peppers or mushrooms – These veggies add color and texture, plus mild sweetness that balances the spice.
- Use pepper jack cheese instead of Parmesan – It brings creamy spice and melty texture that pairs well with Cajun seasoning.
- Stir in fresh spinach or kale at the end – For a quick green boost that softens in the warm sauce without extra cooking time.

How Much Time Will You Need?
This recipe takes about 15 minutes of prep time. Then, cook the chicken on low for 4-5 hours (or on high for 2-3 hours). After shredding the chicken, add pasta and cream, and cook for another 30-40 minutes until the pasta is tender. Overall, plan for around 5 hours, mostly hands-off cooking.
Step-by-Step Instructions:
1. Prepare and Sear the Chicken:
Rub the chicken breasts on both sides with 1 tablespoon of Cajun seasoning. Heat olive oil in a skillet over medium-high heat and sear the chicken for 2-3 minutes on each side until golden brown but not fully cooked. Set aside.
2. Set Up the Crock Pot:
Layer the thinly sliced onions and minced garlic on the bottom of the crock pot. Spread the drained diced tomatoes on top.
3. Add Chicken and Seasoning:
Place the seared chicken breasts on top of the onion and tomato layers. Sprinkle the remaining 1 tablespoon of Cajun seasoning over the chicken.
4. Add Broth and Cook:
Pour the chicken broth into the crock pot, then cover and cook on low for 4-5 hours or on high for 2-3 hours until the chicken is tender and cooked through.
5. Shred Chicken:
Remove the chicken breasts from the crock pot and shred them using two forks.
6. Add Pasta and Cream:
Return the shredded chicken to the crock pot. Add the uncooked pasta and pour in the heavy cream. Stir everything together to combine.
7. Cook the Pasta:
Cover and cook on high for 30-40 minutes, stirring occasionally to prevent sticking, until the pasta is tender.
8. Finish with Cheese and Seasoning:
Stir in the shredded Parmesan cheese. Add salt and pepper to taste, mixing everything well.
9. Serve and Garnish:
Serve the pasta hot, garnished with freshly chopped parsley for a pop of color and freshness. Enjoy your creamy, flavorful Crock Pot Cajun Chicken Pasta!
Can I Use Frozen Chicken in This Recipe?
Yes, but be sure to fully thaw the chicken before cooking. Using frozen chicken can increase the cooking time and may lead to uneven cooking in the crock pot.
Can I Substitute the Heavy Cream?
You can use half-and-half for a lighter sauce or coconut milk for a dairy-free alternative, but the sauce may be less rich and creamy.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove or in the microwave, stirring occasionally to keep the sauce creamy.
Can I Add Vegetables to This Recipe?
Definitely! Bell peppers, mushrooms, or spinach work great. Add firm veggies like bell peppers early with the onions, and add delicate greens like spinach toward the end.
