Slice your potatoes into thin slices (1/8 inch is awesome). The easiest way to do this is with a food processor. A mandolin comes in second place for ease, a cheese grater third, and a knife in very last place.
Place your potato slices in a medium-sized mixing bowl. Pour in the cream and stir in the crushed garlic, parmesan cheese, nutmeg, salt, and pepper. Stir together until everything is coated and then transfer it all to a
slow cooker
Cook on low for 6-8 hours or on high for 3-4 hours.
**Optional, top with shredded cheddar cheese 1 hour before you plan on serving. A little more cheese sounds just about right.
