Crock pot creamy Cajun chicken pasta is a wonderfully easy dish that combines tender chicken, spicy Cajun seasoning, and a rich, creamy sauce all cooked slowly to perfection. The pasta soaks up the flavorful sauce, making every bite smooth and satisfying with just the right kick of spice.
I love how simple this recipe is to throw together—just toss your ingredients into the crock pot and let it do all the work while you go about your day. The Cajun seasoning gives it a nice smoky heat that’s balanced by the creamy sauce, so it’s never too spicy but always full of flavor. It’s one of those meals that feels homemade but requires very little effort.
My favorite way to serve this pasta is with a sprinkle of fresh parsley or a little extra cheese on top. It’s perfect for busy weeknights when you want something comforting and filling without standing over the stove. Plus, it tastes even better the next day, making great leftovers for lunch or dinner.
Key Ingredients & Substitutions
Chicken breasts: They stay tender and cook evenly in the crock pot. You can substitute with boneless thighs for a juicier bite or use pre-cooked chicken to save time.
Cajun seasoning: This is the heart of the flavor with its spicy, smoky notes. If you don’t have it on hand, mix paprika, garlic powder, onion powder, cayenne, oregano, and thyme as a quick fix.
Cream cheese and heavy cream: These create the rich, creamy sauce. For a lighter version, try half-and-half or sour cream. Just know the sauce won’t be as thick or rich.
Pasta: Fettuccine is classic here, but any flat or tubular pasta works. Add uncooked pasta right into the crock pot to soak up the sauce as it cooks.
Parmesan cheese: It melts into the sauce and adds umami depth. Pecorino Romano or Asiago can work well too.
How Do You Keep Chicken Tender and Juicy in the Crock Pot?
Slow cooking chicken can sometimes dry it out, but here’s how to avoid that:
- First, sear the chicken briefly in a hot pan. This locks in juices and adds flavor with a caramelized crust.
- Keep the chicken on top of the sauce, not submerged, so it steams gently without becoming rubbery.
- Cook on LOW for better tenderness if you have time; HIGH works if you’re short on it.
- Remove chicken before adding pasta to prevent overcooking, then shred or slice it before returning it to the sauce.
Following these steps leads to juicy, flavorful chicken that melts into the creamy Cajun sauce.
Equipment You’ll Need
- Crock pot/slow cooker – this is the star here; it cooks everything low and slow without needing your attention.
- Skillet – great for searing chicken to lock in flavor before slow cooking.
- Wooden spoon or heat-safe spatula – perfect for stirring the creamy sauce and pasta without scratching your crock pot.
- Chef’s knife and cutting board – you’ll need these to chop onions and garlic easily.
- Measuring cups and spoons – to get your Cajun seasoning and liquids just right.
Flavor Variations & Add-Ins
- Swap chicken breasts for smoked sausage slices; they bring a smoky depth and a different texture.
- Add bell peppers or spinach for extra color, crunch, and nutrition that blend well with the creamy sauce.
- Stir in a little cayenne or hot sauce if you like more heat beyond the Cajun seasoning.
- Use cheddar or pepper jack cheese instead of Parmesan for a sharper or spicier flavor twist.

For the Chicken and Sauce:
- 1 ½ pounds boneless, skinless chicken breasts
- 2 teaspoons Cajun seasoning (plus extra for chicken)
- 3 cloves garlic, minced
- 1 small onion, finely chopped
- 1 ½ cups chicken broth
- 2 cups heavy cream
- 8 ounces cream cheese, softened and cut into chunks

How Much Time Will You Need?
This dish takes about 15 minutes of prep time, with 4 to 5 hours of slow cooking on low or 2 to 3 hours on high. Then an extra 20 to 30 minutes to cook the pasta right in the crock pot before serving.
Step-by-Step Instructions:
1. Prepare and Sear the Chicken:
Start by seasoning the chicken breasts with Cajun seasoning, salt, and pepper on both sides. Heat olive oil in a skillet over medium-high heat and sear the chicken until golden brown, about 3 to 4 minutes per side. This step locks in the flavor and juices. Set the chicken aside when done.
2. Mix the Sauce in the Crock Pot:
Into your slow cooker, add the minced garlic, chopped onion, chicken broth, heavy cream, and cream cheese chunks. Stir gently to help the cream cheese start melting into the liquids.
3. Cook the Chicken with the Sauce:
Place the seared chicken breasts on top of the sauce in the crock pot. Sprinkle with 2 teaspoons of Cajun seasoning for extra flavor. Cover and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours until the chicken is tender and cooked through.
4. Add the Pasta and Finish the Dish:
About 30 minutes before you want to eat, remove the chicken and shred or slice it as you like. Then break the uncooked pasta in half and add it to the crock pot, stirring it to coat with the sauce. Cover and cook on HIGH for 20 to 30 minutes, stirring occasionally, until the pasta is tender. Return the shredded chicken to the crock pot, add the Parmesan cheese, and stir until it’s melted and creamy.
5. Serve and Enjoy:
Taste and adjust with salt, pepper, or more Cajun seasoning if you want more spice. Serve the pasta hot, garnished with freshly chopped parsley to brighten up the dish.
Can I Use Frozen Chicken in This Recipe?
Yes, you can use frozen chicken, but make sure to thaw it completely in the fridge overnight before starting. This helps the chicken cook evenly and safely in the crock pot.
Can I Substitute the Cream Cheese or Heavy Cream?
Absolutely! For a lighter option, you can use half-and-half or sour cream instead of heavy cream, though the sauce will be less rich. Greek yogurt can also work if added at the end to avoid curdling.
How Do I Prevent the Pasta from Getting Mushy?
To keep your pasta from overcooking, add it during the last 20-30 minutes of cooking and stir occasionally. Breaking the pasta in half helps it cook evenly in the sauce.
Can I Make This Recipe Ahead of Time?
Yes! Prepare the chicken and sauce in the crock pot as directed, then cool and refrigerate. Add and cook the pasta fresh when ready to serve for best texture.
