Ingredients

  • Cooking spray
  • 5-6 cups thinly sliced potatoes sliced to around 1/8-1/4 inch thickness
  • 2 cups extra thin sliced onions
  • 2 1/2 - 3 cups milk start with 2 1/2 cups and add a little more if necessary
  • 1/4 cup flour
  • 3 teaspoons salt
  • 3/4 teaspoons pepper
  • 1/4 heaping cup grated Romano cheese optional

Instructions

  1. Spray a 9" x 13" baking pan with cooking spray.
  2. Spread a layer of potatoes along the bottom of the pan to cover it (they can and will overlap a bit).
  3. Sprinkle half of the onions, 1 teaspoon of salt and 1/4 teaspoon of pepper onto the potatoes.
  4. Spread a layer of potatoes onto this.
  5. Sprinkle half of the onions, 1 teaspoon of salt and 1/4 teaspoon of pepper on top.
  6. Layer the remaining potatoes on top and sprinkle with the remaining salt and pepper.
  7. Whisk together the flour and milk and pour it over the layers of potatoes. It should almost but not completely cover them and you can add a little more milk if needed.
  8. If using Romano cheese sprinkle it on top of the potato mixture.
  9. At this point you can cover and refrigerate until you're ready to bake.
  10. When you're ready to bake them, preheat the oven to 400 degrees.
  11. Bake for 1 hour until golden brown and crispy on top (if not using the Romano cheese, these won't get as brown).
  12. Serve immediately.
