How to Make Crock Pot Creamy Cajun Chicken Pasta Recipe

Step 1: Prep the chicken and veggies

Pat the chicken breasts dry with paper towels and trim any excess fat. Slice the onion and bell peppers into thin strips. Mince the garlic or measure out jarred minced garlic.

Place the chicken breasts in the bottom of the slow cooker in a single layer. Scatter the sliced onions, bell peppers, and garlic over and around the chicken.

Step 2: Mix the sauce base

In a medium bowl, whisk together the chicken broth, cream of chicken soup, heavy cream, Cajun seasoning, smoked paprika, garlic powder, onion powder, thyme, oregano, black pepper, and salt. Whisk until the mixture looks smooth and no big clumps of soup remain. Taste a small spoonful and adjust the Cajun seasoning or salt if needed.

Pour this sauce mixture evenly over the chicken and veggies in the slow cooker. Nestle everything so the liquid mostly covers the chicken.

Step 3: Slow cook the chicken

Cover the slow cooker with the lid. Cook on low for 3 to 4 hours, or on high for about 2 to 2½ hours, until the chicken feels very tender and reaches 165°F in the thickest part. I prefer the low setting, since it gives the chicken a softer, shreddable texture.

Avoid lifting the lid too often, since that drops the temperature and extends the cooking time. Use the last 20 minutes to start boiling water for the pasta.

Step 4: Cook the pasta

Bring a large pot of salted water to a boil. Add the pasta and cook it 1 to 2 minutes less than the package directions for al dente. This keeps the pasta from turning soft when it sits in the sauce.

Drain the pasta, then toss it with a tablespoon of olive oil so it does not stick together. Set it aside while you finish the sauce.

Step 5: Shred the chicken

When the chicken finishes cooking, transfer the breasts to a cutting board. Use two forks to shred the chicken into bite size pieces. You can also chop it with a knife if you like neater chunks.

Return the shredded chicken to the slow cooker and stir it into the sauce and veggies. Make sure the chicken mixes evenly with the flavorful liquid.

Step 6: Add the cheeses and finish the sauce

Add the cream cheese cubes to the slow cooker. Stir until the cream cheese melts into the hot sauce and turns it creamy and thick. Add the shredded Parmesan and mozzarella, then stir again until they melt and blend into the sauce.

If the sauce feels too thick, splash in a bit more warm broth or a little milk until it reaches your ideal consistency. Taste and adjust seasoning with more Cajun blend, salt, or pepper.

Step 7: Combine with pasta

Add the cooked pasta to the slow cooker. Gently fold the pasta into the creamy Cajun chicken mixture until every piece gets coated. Let the pasta sit in the sauce on warm for about 5 to 10 minutes so it absorbs flavor.

If the pasta soaks up too much sauce, add a small splash of broth or cream to loosen it. Sprinkle chopped fresh parsley and extra Parmesan on top right before serving.

Recipe Variations

Gluten free: Use gluten free pasta and a gluten free cream soup, and double check your Cajun seasoning label.
Low carb: Skip the pasta and serve the creamy Cajun chicken over zucchini noodles, spaghetti squash, or steamed cauliflower.
Vegan style: Use plant based chicken strips, vegetable broth, coconut milk or cashew cream, vegan cream cheese, and vegan cheese shreds, and choose a vegan cream style soup.
Extra protein: Add sliced smoked sausage at the start, or stir in cooked shrimp during the last 10 minutes on warm.
More veggies: Stir in spinach, kale, or peas during the last 5 minutes, or add mushrooms at the beginning with the peppers.
Extra spicy: Add cayenne pepper or crushed red pepper flakes to the sauce mix, or drizzle hot sauce on individual servings.
Kid friendly mild: Cut the Cajun seasoning in half and skip extra spicy add ins, then serve more seasoning at the table.

Ways to Serve Crock Pot Creamy Cajun Chicken Pasta Recipe

Spoon the pasta into bowls and top with extra Parmesan and chopped parsley.
Serve with a simple green salad and garlic bread or crusty baguette.
Pair with steamed broccoli, green beans, or roasted carrots for more veggies.
Pack leftovers into meal prep containers with a side of cucumber slices or a small side salad.
Serve over a bed of sautéed zucchini noodles if you want to stretch the sauce and lighten the carbs.

Storage Success

Store leftover Crock Pot Creamy Cajun Chicken Pasta Recipe in an airtight container in the fridge for up to 3 to 4 days. The sauce thickens as it chills, so stir in a splash of milk or broth when you reheat it on the stove or in the microwave. Heat gently and stir often so the creamy sauce stays smooth.

You can freeze portions without the pasta for up to 2 months, then thaw in the fridge and add freshly cooked pasta when you reheat. This method keeps the texture of the pasta much nicer.
