Pre-heat oven to 400 degrees

Wash and dry potatoes 

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 

Top with cheese and bake at 400 degrees on middle rack for 35-40 minutes 

If you want the top to brown even more, move dish to top rack in the oven for last 10 minutes
