1 onion (again, I puree all my onions, but you don't have to, you could dice them instead)
5 smaller, semi peeled potatoes (cut into pieces. smaller sized if you want to cook faster)
Garlic cloves or garlic powder to your preference
Optional (chives, red pepper, cayenne pepper, etc...)
Put ingredients in pot or crockpot and put enough water in to cover the potatoes. Boil until potatoes are soft enough to mash with a whisk and add milk. I like my soup a bit chunkier so I don't add that much milk.
