Make sure to peel and chop all of the potatoes into about 1-inch cubes.
To the slow cooker, add in the broth, cubed potatoes, butter, onion, garlic, salt, and pepper.
Cover and cook on high for about 4-5 hours or low for about 6-7 hours. It's done when potatoes will mash easily with a fork.
Once done, add in the room temperature cream cheese and using an immersion hand blender, blend cream cheese and potatoes until soup is smooth and creamy. (if you only have a blender, take about 2 cups at a time from crockpot and blend together in blender, until all the soup is pureed and smooth)
Serve warm, topped with shredded cheddar cheese, sour cream and bacon bits and all your favorite potato toppings! Drizzle in some heavy cream to add creaminess and to cool off for little ones.
