Instructions
Preheat oven to 350°
Wash and slice potatoes to 1/4"- 3/8".
Arrange potatoes in a 12" cast iron skillet or 13x9 pan.
In a medium saucepan over medium-high heat, melt butter then stir in onion and garlic.
Cook for 1 minute, then add in flour and stir until combined.
Slowly pour in the milk and chicken broth and whisk to combine the sauce so it's smooth and creamy.
Let the sauce come to a simmer over medium heat.
Add a pinch of salt and pepper.
Add any additional items at this time and blend well.
Pour sauce over potatoes.
Cover with foil.
Bake at 350° for 30 minutes, remove the cover, and continue baking for 25 minutes, until golden and bubbly. If you want it more golden brown broil on high for 1-2 minutes.
Remove from oven and allow to cool for 10 minutes before serving, this will allow the sauce to thicken.
Top with sliced green onion or fresh herbs, salt, and pepper if desired.
Notes
add a cut or two grated cheese to the sauce for Au Gratin potatoes.
