Description
A delicious scalloped potato dish perfect for gatherings.
Ingredients
Scale
- Cooking spray
- 5–6 cups thinly sliced Yukon Gold potatoes (sliced to around ⅛-inch thickness (use a mandolin for consistency))
- 2 cups very thin sliced sweet onions
- 3 cups whole milk
- ⅓ cup flour
- 2–3 teaspoons Kosher salt
- ¾ teaspoon ground black pepper
- 1 cup grated Sharp cheddar cheese
- ¼ cup grated Romano cheese
- 2 teaspoons fresh chopped parsley
Instructions
- Preheat the oven to 400 degrees and spray a 9×13-inch baking pan with cooking spray.
- Arrange a single layer of the sliced potatoes along the bottom of the prepared pan, allowing them to overlap slightly, if needed.
- Evenly distribute half of the sliced sweet onions over this potato layer, then season with 1 teaspoon of Kosher salt and ¼ teaspoon of ground black pepper.
- Add another layer of potatoes on top, followed by the remaining half of the onions, another 1 teaspoon of salt, and another ¼ teaspoon of pepper.
- Place the final layer of remaining potatoes over the onions and give it just a light sprinkle of salt and pepper.
- In a separate bowl, whisk the flour into the 3 cups of whole milk until smooth.
- Pour this milk mixture evenly over the layered potatoes in the pan. The liquid should almost, but not completely, cover the potatoes (add a splash more milk if needed).
- Sprinkle the top evenly with the grated Sharp cheddar cheese, the grated Romano cheese, and the fresh chopped parsley.
- Place the pan in the oven and bake for 1 hour, or until the top is golden brown and crispy.
- Once baked, allow the scalloped potatoes to rest for 15-20 minutes before serving to ensure a rich, thickened sauce and prevent a watery dish.
Notes
- Allowing the dish to rest is important for a perfect texture.
- Can substitute ingredients based on preference (e.g., different types of cheese).
