Preheat oven to 350˚F.
Sauce
To make the sauce, melt butter, onion and garlic over medium low heat. Cook until onion is softened, about 3 minutes. Add flour and cook for 1-2 minutes.
Reduce heat to low. Combine milk and broth. Add a small amount at a time whisking to thicken. The mixture will become very thick, continue adding a little bit of liquid at a time whisking until smooth.
Once all of the liquid has been added, bring to a boil over medium heat while continuing to whisk. Stir in salt and pepper and let boil 1 minute.
Assembly
Grease a 9″x13″ baking dish. Place ⅓ of the potatoes in the bottom and season with salt and pepper. Pour ⅓ of the cream sauce sauce over top.
Repeat layers ending with cream sauce. Cover and bake for 45 minutes.
Uncover and bake for an additional 35-45 minutes or until golden brown and potatoes are tender. Broil for 3-4 minutes to obtain a golden top.
Allow to rest for 15 minutes before serving.
