Using either a sharp knife, mandolin, or a slicer attachment to a food processor, slice potatoes very thin at around ⅛ inch thickness
Measure out 1 cup of milk and add in garlic. Stir together.
Grease your baking dish and start with the first layer of potatoes, stacking them like dominos on top of each other. Add salt and pepper to potatoes and then add a layer of milk.
Repeat this until all ingredients have been added to baking dish
