In a small mixing bowl, mix the cream, chicken broth, garlic and salt and pepper.
Spray your crock pot with non cooking spray.
Put a layer of the potatoes in the bottom of your crock pot (⅓ of your total amount of potatoes).
Top with ⅓ of the cream mixture and ⅓ of each of the cheddar cheese and parmesan cheese amounts.
Continue these process until all the ingredients have been layered in the crock pot.
Cover and cook on high for 3-4 hours until the potatoes are tender.
Top with parsley (optional).
Serve immediately.
