Place 2 pounds chicken breasts in the bottom of a 6?quart crock pot. Pour 2 cups heavy whipping cream and 4 cups chicken broth over the chicken. Add 4 tablespoons butter, 2 tablespoons Cajun seasoning, and ½ teaspoon garlic powder to the crock pot. Stir gently to combine with the liquids and chicken.
Cover and cook on low for 4-6 hours or on high for 2-3 hours until the chicken is cooked through (has an internal temperature of 165 degrees F).
Remove the chicken from the crock pot and shred or dice it into large pieces.
Remove the chicken from the crock pot and shred it using two forks; return the shredded chicken back to the crock pot. Add 1 pound penne pasta to the crock pot with the shredded chicken. Stir to combine.
Cover and cook on high for 20-30 minutes until the pasta is tender and cooked through.
Stir in 1 cup grated Parmesan cheese until melted and evenly mixed into the creamy sauce.
Serve warm and enjoy!
