Depending on the number of people you will have to decide on the number of Potatoes you will need.
Scrub the potatoes (I usually use Gold Potatoes) and dice. (Leaving the skins on the potatoes)
1-2 onions chopped.
Put them together in your slow cooker and add enough water to cover by about 2 inches. Cook on high until the potatoes and onions are almost completely cooked.
Add, Garlic Salt, Dried Basil, and 2-3 cans of Chicken Broth.
Add, 3-4 Cups of Grated Cheese - - I use 1/2 Cheddar 1/2 Pepperjack.
Turn on Low, and cook for about 2 hours -- slightly mash the potatoes and onions and add 2 Cups of Milk- - continue cooking on low until you are ready to bring out the bowls and spoons.....Enjoy!
