  • 3 pounds potatoes, thinly sliced
  • ½ onion, thinly sliced
  • 9 tablespoons all-purpose flour, divided
  • 6 tablespoons butter, diced and divided
  • Salt and ground black pepper to taste
  • 3 cups whole milk, or as needed


  1. Preparation:
    Preheat your oven to 375 degrees F (190 degrees C) and generously grease a 9×13-inch baking dish.
  2. Layering:
    Spread about 1/3 of the potato slices on the bottom of the prepared baking dish, followed by 1/3 of the sliced onions. Sprinkle 3 tablespoons of flour over the potatoes and onions, and arrange 2 tablespoons of diced butter atop the flour. Season the entire layer with salt and pepper. Repeat this layering process twice more.
  3. Milk Mixture:
    Heat the whole milk in a saucepan until warm. Pour enough warm milk over the layers in the baking dish so that the top of the liquid is level with the final layer of potatoes.
  4. Baking:
    Bake in the preheated oven until the potatoes are tender, approximately 45 to 60 minutes.


  • Potato Thickness:
    Ensure uniform potato slices for even cooking. Using a mandoline slicer can help achieve the desired thickness.
  • Cheese Variation:
    For a cheesy twist, sprinkle a layer of your favorite shredded cheese between the potato layers.
  • Herb Infusion:
    Experiment with adding herbs like thyme or rosemary to enhance the flavor profile.
