These Au Gratin Potatoes with American Cheese are a classic comfort food side dish recipe from my family's Chicago supper club restaurant. This tasty side dish is loaded with cheeses, milk, potatoes, and spices! Served in casserole dishes or individual ramekins for the perfect accompaniment to your dinner.
Peel potatoes, and boil them in a pot of hot water for about 30-40 minutes, until tender. Drain and set aside to cool.
Once cool, grate the potatoes with a regular cheese grater.
In a pan over medium heat: melt butter, add flour and blend slowly. Add 1/2 of the milk and all of the cheese. When cheese is melted add salt and remaining milk. Add grated potatoes and mix well until a medium custard consistency forms.
Place potatoes in individual casserole dishes or ramekins. Sprinkle parmesan cheese and paprika on top. Bake in hot over or broiler until cheese is bubbling. Enjoy!
