Instructions

Preheat the oven to 400°F and grease a 9×13 inch baking dish with cooking spray.
Layer half the sliced potatoes in the dish, followed by half the onions, 1 teaspoon of salt, and 1/4 teaspoon pepper. Repeat the layers, finishing with the remaining potatoes, salt, and pepper.
In a separate bowl, whisk together the flour and milk until smooth. Pour over the layered potatoes until nearly covered.
Sprinkle Romano cheese on top if using. Bake uncovered for 1 hour until golden and bubbly.
Let the dish cool for 10 minutes before serving to allow it to set.

Notes

For a cheesy twist, add cheddar or Gruyère to the sauce.
Minced garlic deepens the flavor when mixed into the milk.
Herbs like thyme or rosemary add a rustic note.
Sour cream or cream cheese can be added for extra creaminess.
Use vegan cheese and almond milk for a dairy-free version.
