Begin by washing the potatoes thoroughly to remove any dirt. Peel them if desired, then slice them thinly, about 1/8 inch thick, for uniform cooking.

In your slow cooker, start layering the sliced potatoes neatly, allowing them to overlap slightly. Pour a generous amount of heavy cream over the potatoes, then sprinkle garlic powder evenly throughout.

Sprinkle salt and pepper over the layered ingredients to enhance the flavors.

Cover the slow cooker with its lid, set it to low heat, and let it cook for about 3 hours.

Once the cooking time is complete, gently stir the scalloped potatoes to mix the creamy sauce throughout.
