Some key quantitative measurements for potato bake include slicing the potatoes to a uniform thickness of about 1/8 inch, maintaining a cream-to-potato ratio of 1:1 for desired creaminess, using a cheese-to-potato ratio of 1 cup per 2 pounds of potatoes, and baking at 350F (175C) for approximately 1 to 1.5 hours for thorough cooking and a golden crust.
