To make in the crock pot, peel potatoes as desired. Add to crock pot with 2 cups of water. Cook overnight on low or on high for 10 hours. 1/2 hour to 1 hour prior to serving, blend the soup base ingredients in the blender. Add butter and chopped onion to a medium saucepan and saute for 5 minutes over medium high heat or until onion becomes translucent. Blend the milk, flour, salt and chicken bullion granules in the blender for 20-30 seconds. Add to the saucepan and simmer for a 3-4 minutes or until sauce thickens. While soup base is simmering to thicken, use a serving spoon to crush the potatoes to desired consistency, or remove potatoes to a cutting board and cut/crush and return to crock pot. Add the soup base to the crock pot. Stir in cheddar cheese, bacon, green onions and sour cream, or serve them as toppings.
