Ingredients
- Cooking spray
- 5-6 cups thinly sliced potatoes sliced to around ⅛-1/4 inch thickness
- 2 cups thin sliced onions
- 3 cups whole milk
- ⅓ cup flour
- 3 teaspoons Kosher salt
- ¾ teaspoons ground black pepper
- ¼ cup grated Romano cheese optional
Instructions
- Preheat the oven to 400 degrees. Spray a 9" x 13" baking pan with cooking spray. Spread a layer of potatoes along the bottom of the pan to cover it (they can and will overlap a bit).
- Sprinkle half of the onions, 1 teaspoon of salt and ¼ teaspoon of pepper onto the potatoes.
- Spread a layer of potatoes onto this.
- Sprinkle half of the onions, 1 teaspoon of salt and ¼ teaspoon of pepper on top.
- Layer the remaining potatoes on top and sprinkle with the remaining salt and pepper.
- 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.
- If using Romano cheese sprinkle it on top of the potato mixture.
- Bake for 1 hour until golden brown and crispy on top (if not using the Romano cheese, these won't get as brown). Cool for 10 minutes and serve immediately.

Notes
- Try to slice the potatoes as thin as possible. Your goal should be to get them to around ⅛-¼-inch in thickness.
- Slice the onions as thinly as possible too, and they’ll melt right into the dish!
- Spray down the baking pan with nonstick cooking spray to help prevent sticking. You could also apply olive oil with a clean paper towel.
- When creating the layers of potatoes, try to make it as even but slightly shingled.
- You want the milk to almost cover the potatoes, but not completely. Start with 2.5 cups. If you need a little more, go for it.
- Bake uncovered so that they get nice and golden brown on top. Adding the cheese also helps with this!
- Ingredients to prep ahead- You can clean the potatoes and slice the onions ahead of time.
- Leftovers and storage- Let the potatoes cool completely before adding any leftovers to an airtight container. You can store them in the refrigerator for up to 4 days. Reheat in 30-second bursts in the microwave, or covered in the oven at 350 degrees F until heated through.
