Peel and dice the potatoes into even-sized pieces.
In the crock pot, layer the diced potatoes at the bottom. Sprinkle ranch seasoning over the potatoes. Add shredded cheese and crumbled bacon on top.
Pour the broth over the layered ingredients, ensuring the liquid covers them.
Cook on low for 7-8 hours or on high for 4 hours, until the potatoes are tender.
Stir in heavy cream, season with salt and pepper. For a smoother soup, use an immersion blender.
Serve with optional garnishes like extra cheese, bacon bits, or chopped green onions.
