No fail Scalloped Potatoes

Ingredients:

3 pounds potatoes, thinly sliced

1 onion, thinly sliced

9 Tbsp. all-purpose flour, divided

6 Tbsp. butter, diced and divided

salt and freshly ground black pepper to taste

3 cups whole milk, or as needed

Method:

1. Preheat oven to 375 degrees F. Grease a 9x13-inch baking dish.

2. Spread about 1/3 of the potato slices onto the bottom of the prepared dish. Top with about 1/3 of the onion slices. Sprinkle 3 tbsp. flour over the potato and onion.  Arrange 2 tbsp. butter over the flour. Season the layer with salt and pepper. Repeat the step 2 more times.

3. Heat milk in a saucepan until warm. Pour enough warm milk over the mixture in the baking dish so the top of the liquid is level with the final layer of potatoes.

4. Bake in oven until potatoes are tender, about 40-60 minutes.

Note:

You can substitute potatoes with yam or sweet potato.
