Peel and dice the potatoes into even-sized pieces.
Place the diced potatoes in the crock pot.
Sprinkle the ranch seasoning mix evenly over the potatoes.
Add the shredded cheddar cheese and crumbled bacon on top of the potatoes.
Pour the chicken broth over the layered ingredients, ensuring the liquid just covers them.
Cover the crock pot and cook on low for 7-8 hours or on high for 4 hours, or until the potatoes are tender.
Stir in the heavy cream.
Season with salt and pepper to taste.
Serve hot, garnished with extra cheese, bacon, or green onions if desired.
