Prepare the Potatoes: Peel and dice the potatoes into even-sized pieces to ensure uniform cooking.
Layer the Ingredients: In the crock pot, place the diced potatoes at the bottom. Sprinkle the ranch seasoning evenly over the potatoes. Add the shredded cheese and crumbled bacon on top.
Add the Broth: Pour the chicken or vegetable broth over the layered ingredients, ensuring that the liquid just covers them.
Cook the Soup: Cover the crock pot and set it to cook on low for 7-8 hours or on high for 4 hours. The soup is ready when the potatoes are tender and easily mashed.
Add Cream and Season: Once the potatoes are cooked, stir in the heavy cream. Season with salt and pepper to taste. For a smoother soup, you can use an immersion blender to puree the soup to your desired consistency.
Serve: Ladle the hot soup into bowls. Garnish with extra cheese, bacon bits, and chopped green onions or chives, if desired.
