1 1/2 pounds potatoes (about 8 small), sliced
1 1/2 teaspoons kosher salt
1/4 teaspoon ground black pepper
1 teaspoon garlic powder
1/2 cup sour cream
1/2 cup grated parmesan
1/4 cup butter
Place potatoes in a large pot with enough water to cover them and add one teaspoon of the salt. Bring to a boil, then reduce heat, cover and simmer for about 20-25 minutes. Meanwhile place the remaining salt, pepper, garlic powder sour cream, parmesan cheese and butter in the bowl of an electric mixer. When the potatoes pierce easily remove from heat and drain. Add the potatoes to the other bowl and mix on medium speed until smooth.
These potatoes were so good that I forgot to get a picture of them until after everybody ate.
