3-4 small russet potatoes, very thinly sliced, or sliced using a mandoline
¾ cup diced ham
Instructions
Preheat oven to 350 degrees.
In a medium saucepan, melt butter over medium-low heat. Once melted, add 4 tbsp. flour and whisk quickly to incorporate. After 30 seconds, add half & half and milk; stir. Whisk constantly, until mixture thickens. Once thick, add cheese and whisk together. Season with salt and pepper.
In a small skillet, melt 1 tbsp. butter then add diced onion. Cook until translucent and aromatic, about 3-4 minutes.
Thinly slice potatoes using a knife or madoline, then add slices to a large bowl of water. Soak potatoes 5-10 minutes, then drain and dab slices dry.
