Add the chicken breasts, heavy whipping cream, chicken broth, butter, garlic powder, and Cajun seasoning to your Crock Pot. Give the ingredients a gentle stir to distribute the seasoning evenly across the chicken.
Set your Crock Pot on low and cook for 4-6 hours (or 2-3 hours on high). This slow cooking ensures the chicken is tender and absorbs all those spicy Cajun flavors. Once the chicken reaches an internal temperature of 165°F, it’s ready for the next step.
Remove the chicken from the pot and shred it using forks or a hand mixer. You can dice it too if you prefer chunkier pieces in your pasta.
Whisk the sauce in the Crock Pot to make sure everything is smooth and well-mixed. Then, return the shredded chicken and stir in the uncooked pasta. The pasta will absorb all that creamy, flavorful goodness as it cooks.
Cover the Crock Pot and cook on high for another 20-30 minutes until the pasta is tender. This is when your kitchen will smell irresistible!
Turn the heat off and stir in freshly grated Parmesan cheese. Place the lid back on for five minutes to allow the cheese to melt fully into the sauce.
Plate the pasta, and don’t forget to garnish with extra Parmesan and a sprinkle of Cajun seasoning for added flair. Dinner is served!
