First, gather your bacon (1 cup out of the cooked 1¼), frozen diced potatoes, chicken broth, cream of chicken soup, cubed cream cheese, ranch dressing mix, pepper, and onion powder. I put them into my 6-quart crock pot so everything starts mingling.
I cover the slow cooker and set it on LOW for 5–6 hours (or HIGH for 2–3 hours) so the potatoes cook through and flavors deepen.
About 15 minutes before serving, I lift the lid, stir to fold in the softened cream cheese fully, then add the half and half and shredded sharp cheddar. I close the lid again to let the cheese melt totally.
Finally, I ladle the soup into bowls, garnish with the remaining ¼ cup of bacon, some extra shredded cheese, and chopped green onion. That final touch makes the presentation and flavour pop.
