In a mixing bowl, whisk together the heavy cream, parmesan cheese, minced garlic, italian seasoning, salt, and black pepper.
Place the chicken breasts in the slow cooker.
Pour the alfredo sauce mixture over the chicken in the slow cooker, making sure they are well-coated.
Cover the slow cooker and cook on LOW for 6-8 hours until the chicken is cooked through and tender. (I don’t recommend cooking this recipe on high as the cheese will burn in the sauce).
Remove the chicken breasts from the slow cooker and shred them using two forks. Return the shredded chicken to the slow cooker and stir it into the alfredo sauce. Stir in the cooked penne pasta.
Serve the slow cooker chicken alfredo and garnish with fresh chopped parsley. Enjoy!

Notes
You can customize this recipe by adding your favorite vegetables or other additions such as cooked bacon, broccoli, sauteed mushrooms, spinach, or sun-dried tomatoes.
If the alfredo sauce is too thick, you can thin it out by adding a little chicken broth or pasta water.
Adjust the seasoning according to your taste preferences. Feel free to add more salt, pepper, or Italian seasoning as desired.
This recipe is specifically designed for cooking on low heat in the slow cooker. Cooking on high heat may cause the cheese to burn.
Leftover slow cooker chicken alfredo can be stored in an airtight container in the refrigerator for up to 3-4 days.
To reheat, you can use the microwave or heat it gently on the stovetop, adding a splash of cream to restore the creamy consistency.
